Here is the big set of staging driver patches for 6.0-rc1.
Another round where we removed more lines of code than added, always a
nice progression. Some of that came from the movement of the vme code
back into staging, and removal of some other of the vme driver code as
there are no known users and it is very obsolete and unmaintained. It
can be added back easily if someone offers to maintain it.
Other than that this merge has lots of little things:
- huge cleanups for r8188eu driver
- minor cleanups for other wifi drivers
- tiny loop fixes for greybus code
- other small coding style fixes
All of these have been in linux-next for a while with no reported
issues.

Here is the big set of Thunderbolt and USB changes for 6.0-rc1.
Lots of little things here, nothing major, just constant development on
some new hardware support and cleanups of older drivers. Highlights of
this pull request are:
- lots of typec changes and improvements for new hardware
- new gadget controller driver
- thunderbolt support for new hardware
- the normal set of new usb-serial device ids and cleanups
- loads of dwc3 controller fixes and improvements
- mtu3 driver updates
- testusb fixes for longtime issues (not many people use this
tool it seems.)
- minor driver fixes and improvements over the USB tree
- chromeos platform driver changes were added and then reverted
as they depened on some typec changes, but the cross-tree
merges caused problems so they will come back later through
the platform tree.
All of these have been in linux-next for a while now with no reported
issues.

Remove the obsolete 'efivars' sysfs based interface to the EFI variable
store, now that all users have moved to the efivarfs pseudo file system,
which was created ~10 years ago to address some fundamental shortcomings
in the sysfs based driver.
Move the 'business logic' related to which EFI variables are important
and may affect the boot flow from the efivars support layer into the
efivarfs pseudo file system, so it is no longer exposed to other parts
of the kernel.

tl;dr: The Enhanced IBRS mitigation for Spectre v2 does not work as
documented for RET instructions after VM exits. Mitigate it with a new
one-entry RSB stuffing mechanism and a new LFENCE.
== Background ==
Indirect Branch Restricted Speculation (IBRS) was designed to help
mitigate Branch Target Injection and Speculative Store Bypass, i.e.
Spectre, attacks. IBRS prevents software run in less privileged modes
from affecting branch prediction in more privileged modes. IBRS requires
the MSR to be written on every privilege level change.
To overcome some of the performance issues of IBRS, Enhanced IBRS was
introduced. eIBRS is an "always on" IBRS, in other words, just turn
it on once instead of writing the MSR on every privilege level change.
When eIBRS is enabled, more privileged modes should be protected from
less privileged modes, including protecting VMMs from guests.
== Problem ==
Here's a simplification of how guests are run on Linux' KVM:
void run_kvm_guest(void)
{
// Prepare to run guest
VMRESUME();
// Clean up after guest runs
}
The execution flow for that would look something like this to the
processor:
1. Host-side: call run_kvm_guest()
2. Host-side: VMRESUME
3. Guest runs, does "CALL guest_function"
4. VM exit, host runs again
5. Host might make some "cleanup" function calls
6. Host-side: RET from run_kvm_guest()
Now, when back on the host, there are a couple of possible scenarios of
post-guest activity the host needs to do before executing host code:
* on pre-eIBRS hardware (legacy IBRS, or nothing at all), the RSB is not
touched and Linux has to do a 32-entry stuffing.
* on eIBRS hardware, VM exit with IBRS enabled, or restoring the host
IBRS=1 shortly after VM exit, has a documented side effect of flushing
the RSB except in this PBRSB situation where the software needs to stuff
the last RSB entry "by hand".
IOW, with eIBRS supported, host RET instructions should no longer be
influenced by guest behavior after the host retires a single CALL
instruction.
However, if the RET instructions are "unbalanced" with CALLs after a VM
exit as is the RET in #6, it might speculatively use the address for the
instruction after the CALL in #3 as an RSB prediction. This is a problem
since the (untrusted) guest controls this address.
Balanced CALL/RET instruction pairs such as in step #5 are not affected.
== Solution ==
The PBRSB issue affects a wide variety of Intel processors which
support eIBRS. But not all of them need mitigation. Today,
X86_FEATURE_RSB_VMEXIT triggers an RSB filling sequence that mitigates
PBRSB. Systems setting RSB_VMEXIT need no further mitigation - i.e.,
eIBRS systems which enable legacy IBRS explicitly.
However, such systems (X86_FEATURE_IBRS_ENHANCED) do not set RSB_VMEXIT
and most of them need a new mitigation.
Therefore, introduce a new feature flag X86_FEATURE_RSB_VMEXIT_LITE
which triggers a lighter-weight PBRSB mitigation versus RSB_VMEXIT.
The lighter-weight mitigation performs a CALL instruction which is
immediately followed by a speculative execution barrier (INT3). This
steers speculative execution to the barrier -- just like a retpoline
-- which ensures that speculation can never reach an unbalanced RET.
Then, ensure this CALL is retired before continuing execution with an
LFENCE.
In other words, the window of exposure is opened at VM exit where RET
behavior is troublesome. While the window is open, force RSB predictions
sampling for RET targets to a dead end at the INT3. Close the window
with the LFENCE.
There is a subset of eIBRS systems which are not vulnerable to PBRSB.
Add these systems to the cpu_vuln_whitelist[] as NO_EIBRS_PBRSB.
Future systems that aren't vulnerable will set ARCH_CAP_PBRSB_NO.

This KUnit update for Linux 5.20-rc1 consists of several fixes and an
important feature to discourage running KUnit tests on production
systems. Running tests on a production system could leave the system
in a bad state. This new feature adds:
- adds a new taint type, TAINT_TEST to signal that a test has been run.
This should discourage people from running these tests on production
systems, and to make it easier to tell if tests have been run
accidentally (by loading the wrong configuration, etc.)
- several documentation and tool enhancements and fixes.

This pull request contains the following branches:
doc.2022.06.21a: Documentation updates.
fixes.2022.07.19a: Miscellaneous fixes.
nocb.2022.07.19a: Callback-offload updates, perhaps most notably a new
RCU_NOCB_CPU_DEFAULT_ALL Kconfig option that causes all CPUs to
be offloaded at boot time, regardless of kernel boot parameters.
This is useful to battery-powered systems such as ChromeOS
and Android. In addition, a new RCU_NOCB_CPU_CB_BOOST kernel
boot parameter prevents offloaded callbacks from interfering
with real-time workloads and with energy-efficiency mechanisms.
poll.2022.07.21a: Polled grace-period updates, perhaps most notably
making these APIs account for both normal and expedited grace
periods.
rcu-tasks.2022.06.21a: Tasks RCU updates, perhaps most notably reducing
the CPU overhead of RCU tasks trace grace periods by more than
a factor of two on a system with 15,000 tasks. The reduction
is expected to increase with the number of tasks, so it seems
reasonable to hypothesize that a system with 150,000 tasks might
see a 20-fold reduction in CPU overhead.
torture.2022.06.21a: Torture-test updates.
ctxt.2022.07.05a: Updates that merge RCU's dyntick-idle tracking into
context tracking, thus reducing the overhead of transitioning to
kernel mode from either idle or nohz_full userspace execution
for kernels that track context independently of RCU. This is
expected to be helpful primarily for kernels built with
CONFIG_NO_HZ_FULL=y.

Pull random number generator updates from Jason Donenfeld:
"Though there's been a decent amount of RNG-related development during
this last cycle, not all of it is coming through this tree, as this
cycle saw a shift toward tackling early boot time seeding issues,
which took place in other trees as well.
Here's a summary of the various patches:
- The CONFIG_ARCH_RANDOM .config option and the "nordrand" boot
option have been removed, as they overlapped with the more widely
supported and more sensible options, CONFIG_RANDOM_TRUST_CPU and
"random.trust_cpu". This change allowed simplifying a bit of arch
code.
- x86's RDRAND boot time test has been made a bit more robust, with
RDRAND disabled if it's clearly producing bogus results. This would
be a tip.git commit, technically, but I took it through random.git
to avoid a large merge conflict.
- The RNG has long since mixed in a timestamp very early in boot, on
the premise that a computer that does the same things, but does so
starting at different points in wall time, could be made to still
produce a different RNG state. Unfortunately, the clock isn't set
early in boot on all systems, so now we mix in that timestamp when
the time is actually set.
- User Mode Linux now uses the host OS's getrandom() syscall to
generate a bootloader RNG seed and later on treats getrandom() as
the platform's RDRAND-like faculty.
- The arch_get_random_{seed_,}_long() family of functions is now
arch_get_random_{seed_,}_longs(), which enables certain platforms,
such as s390, to exploit considerable performance advantages from
requesting multiple CPU random numbers at once, while at the same
time compiling down to the same code as before on platforms like
x86.
- A small cleanup changing a cmpxchg() into a try_cmpxchg(), from
Uros.
- A comment spelling fix"
More info about other random number changes that come in through various
architecture trees in the full commentary in the pull request:

After v5.19 had all drivers converted to the new atomic API and nobody
has reported any breakage, this set of changes starts by dropping the
legacy support.
Some existing drivers get improvements and broader chip support and a
new driver is added that emulates a PWM controller using a clock output.
Other than that there's the usual bits of cleanups and minor fixes.

The big update this time around is some excellent work from David Jander
who went through the fast path and really eliminated overheads, meaning
that we are seeing a huge reduction in the time spent between transfers
for single threaded clients. Benchmarking has been coming out at about a
halving of overhead which is clearly visible in system level usage that
stresses SPI like some CAN and IIO applications, especially with small
transfers. Thanks to David for taking the time to drill down into this
and push the work upstream.
Otherwise there's been a bunch of new device support and the usual
- Optimisation of the fast path, particularly around the number and
types of locking operations, from David Jander.
- Support for Arbel NPCM845, HP GXP, Intel Meteor Lake and Thunder Bay,
MediaTek MT8188 and MT8365, Microchip FPGAs, nVidia Tegra 241 and
Samsung Exynos Auto v9 and 4210.

Instead of listing directly properties typical for SPI peripherals,
reference the spi-peripheral-props.yaml schema. This allows using all
properties typical for SPI-connected devices, even these which device
bindings author did not tried yet.
Remove the spi-* properties which now come via spi-peripheral-props.yaml
schema, except for the cases when device schema adds some constraints
like maximum frequency.
While changing additionalProperties->unevaluatedProperties, put it in
typical place, just before example DTS.

These drivers are rather uncomfortably hammered into the

This adds initial support for two SoC families that have been under
review for a while. In both cases, the origonal idea was to have a
minimally functional version, but we ended up leaving out the clk drivers
that are still under review and will be merged through the corresponding
subsystem tree.
The Nuvoton NPCM8xx is a 64-bit Baseboard Management Controller and
based on the 32-bit NPCM7xx family but is now getting added to
arch/arm64 as well.

As usual, the bulk of the changes for the SoC tree are devicetree file
updates, and most of these changes are for 64-bit embedded machines.
As before, there are a ton of style cleanups, and additional hardware
support for existing machines.
Looking only at the new SoC, the notable additions are:
- A whole family of Broadcom broadband SoCs, both 32-bit and 64-bit:
BCM63178, BCM63158, BCM4912, BCM6858, BCM6878, BCM6846, BCM63146,
BCM6856, BCM6855, BCM6756, BCM63148, and BCM6813.
Each SoC comes with a corresponding reference board.
- The new NXP i.MX93 SoC, the follow-up to the popular i.MX6 and
i.MX8 embedded SoCs, now using Cortex-A55 cores and the
Ethos-U65 NPU.
- Qualcomm Snapdragon 8cx Gen3 (SC8280XP), the current high end
of Arm based Laptop SoCs, and its automotive cousin, the
SA8540P. The SC8280XP is used in the Lenovo Thinkpad X13s
laptop that also gets added here in addition to the reference
boards.
- Allwinner H616, a newer version of the H6 SoC, targeted at
Set-top-box applications. It comes with dts files for the
Orange Pi zero2 single-board computer and the X96 Mate
set-top-box
- Marvell Prestera 98DX2530 (AlleyCat5), a network switch chip
in the Armada SoC family based on the Cortex-A55 core.
New machines based on previously supported SoCs include:
- Several new machines on NXP i.MX platforms: multiple Toradex
Colibri boards using the "Iris" and "Ixora" carriers,
DH electronics i.MX8M Plus DHCOM and PDK2, TQ-Systems
TQMa8MPQL, and phytech phyBOARD-Polis-i.MX8MM.
- Google Chameleon v3 FPGA board based on Intel Arria10 and
Stratix 10 Software Virtual platform, both in the SoCFPGA
platform.
- Two new wireless devices based on Broadcom SoCs:
The Asus GT-AX6000 Router and the Cisco Meraki MR26 access point
- Improved Chromebook support for both the Mediatek and Qualcomm
SoC families brought added machines: Acer Chromebook 514 (MT8192),
Acer Chromebook Spin 513 (MT8195) and a couple of SC7180 based
machines including the Lenovo IdeaPad Chromebook Duet 3.
- Xiaomi Mi Mix2s, LG G7 and LG V35 are mobile phones based on
Qualcomm SDM845, while Mi 5s Plus is based on MSM8996.
- Finally, there are a few development board on other chips:
PCB8309 (Microchip lan966x), Radxa Rock Pi S (Rockchips RK3308)
DH DRC Compact (ST STM32MP1) and Inforce IFC6560 (Qualcomm
SDM660)

Merge tag 'fs.idmapped.overlay.acl.v5.20' of git://git.kernel.org/pub/scm/linux/kernel/git/brauner/linux
Pull acl updates from Christian Brauner:
"Last cycle we introduced support for mounting overlayfs on top of
idmapped mounts. While looking into additional testing we realized
that posix acls don't really work correctly with stacking filesystems
on top of idmapped layers.
We already knew what the fix were but it would require work that is
more suitable for the merge window so we turned off posix acls for
v5.19 for overlayfs on top of idmapped layers with Miklos routing my
patch upstream in 72a8e05d4f ("Merge tag 'ovl-fixes-5.19-rc7' [..]").
This contains the work to support posix acls for overlayfs on top of
idmapped layers. Since the posix acl fixes should use the new
vfs{g,u}id_t work the associated branch has been merged in. (We sent a
pull request for this earlier.)
We've also pulled in Miklos pull request containing my patch to turn
of posix acls on top of idmapped layers. This allowed us to avoid
rebasing the branch which we didn't like because we were already at
rc7 by then. Merging it in allows this branch to first fix posix acls
and then to cleanly revert the temporary fix it brought in by commit
4a47c6385b ("ovl: turn of SB_POSIXACL with idmapped layers
temporarily").
The last patch in this series adds Seth Forshee as a co-maintainer for
idmapped mounts. Seth has been integral to all of this work and is
also the main architect behind the filesystem idmapping work which
ultimately made filesystems such as FUSE and overlayfs available in
containers. He continues to be active in both development and review.
I'm very happy he decided to help and he has my full trust. This
increases the bus factor which is always great for work like this. I'm
honestly very excited about this because I think in general we don't
do great in the bringing on new maintainers department"

ASoC: More updates for v5.20
More updates that came in since the last pull request I sent, a series
of driver specific changes:
- Support for AMD RPL, some Intel platforms and Mediatek MT8186.
KVM/s390, KVM/x86 and common infrastructure changes for 5.20
x86:
* Permit guests to ignore single-bit ECC errors
* Fix races in gfn->pfn cache refresh; do not pin pages tracked by the cache
* Intel IPI virtualization
* Allow getting/setting pending triple fault with KVM_GET/SET_VCPU_EVENTS
* PEBS virtualization
* Simplify PMU emulation by just using PERF_TYPE_RAW events
* More accurate event reinjection on SVM (avoid retrying instructions)
* Allow getting/setting the state of the speaker port data bit
* Refuse starting the kvm-intel module if VM-Entry/VM-Exit controls are inconsistent
* "Notify" VM exit (detect microarchitectural hangs) for Intel
* Cleanups for MCE MSR emulation
s390:
* add an interface to provide a hypervisor dump for secure guests
* improve selftests to use TAP interface
* enable interpretive execution of zPCI instructions (for PCI passthrough)
* First part of deferred teardown
* CPU Topology
* PV attestation
* Minor fixes
Generic:
* new selftests API using struct kvm_vcpu instead of a (vm, id) tuple
x86:
* Use try_cmpxchg64 instead of cmpxchg64
* Bugfixes
* Ignore benign host accesses to PMU MSRs when PMU is disabled
* Allow disabling KVM's "MONITOR/MWAIT are NOPs!" behavior
* x86/MMU: Allow NX huge pages to be disabled on a per-vm basis
* Port eager page splitting to shadow MMU as well
* Enable CMCI capability by default and handle injected UCNA errors
* Expose pid of vcpu threads in debugfs
* x2AVIC support for AMD
* cleanup PIO emulation
* Fixes for LLDT/LTR emulation
* Don't require refcounted "struct page" to create huge SPTEs
x86 cleanups:
* Use separate namespaces for guest PTEs and shadow PTEs bitmasks
* PIO emulation
* Reorganize rmap API, mostly around rmap destruction
* Do not workaround very old KVM bugs for L0 that runs with nesting enabled
* new selftests API for CPUID
- Check the IBPB feature flag before enabling IBPB in firmware calls
because cloud vendors' fantasy when it comes to creating guest
configurations is unlimited
- Unexport sev_es_ghcb_hv_call() before 5.19 releases now that HyperV
doesn't need it anymore
- Remove dead CONFIG_* items

Per task wakeup while not running (wwnr) monitor.
This model is broken, the reason is that a task can be running in the
processor without being set as RUNNABLE. Think about a task about to
sleep:
1: set_current_state(TASK_UNINTERRUPTIBLE);
2: schedule();
And then imagine an IRQ happening in between the lines one and two,
waking the task up. BOOM, the wakeup will happen while the task is
running.
Q: Why do we need this model, so?
A: To test the reactors.

The wakeup in preemptive (wip) monitor verifies if the
wakeup events always take place with preemption disabled:
|
|
v
#==================#
H preemptive H <+
#==================# |
| |
| preempt_disable | preempt_enable
v |
sched_waking +------------------+ |
+--------------- | | |
| | non_preemptive | |
+--------------> | | -+
+------------------+
The wakeup event always takes place with preemption disabled because
of the scheduler synchronization. However, because the preempt_count
and its trace event are not atomic with regard to interrupts, some
inconsistencies might happen.
The documentation illustrates one of these cases.

memory.reclaim is a cgroup v2 interface that allows users to proactively
reclaim memory from a memcg, without real memory pressure. Reclaim
operations invoke vmpressure, which is used: (a) To notify userspace of
reclaim efficiency in cgroup v1, and (b) As a signal for a memcg being
under memory pressure for networking (see
mem_cgroup_under_socket_pressure()).
For (a), vmpressure notifications in v1 are not affected by this change
since memory.reclaim is a v2 feature.
For (b), the effects of the vmpressure signal (according to Shakeel [1])
are as follows:
1. Reducing send and receive buffers of the current socket.
2. May drop packets on the rx path.
3. May throttle current thread on the tx path.
Since proactive reclaim is invoked directly by userspace, not by memory
pressure, it makes sense not to throttle networking. Hence, this change
makes sure that proactive reclaim caused by memory.reclaim does not
trigger vmpressure.

The ARCH_GENERIC_PCI_MMAP_RESOURCE symbol came up in a recent discussion,
and I noticed that this was left behind by an unfinished cleanup from 2017.
The only architecture that still relies on providing its own
pci_mmap_page_range() helper instead of using the generic
pci_mmap_resource_range() is sparc. Presumably the reasons for this have
not changed, but at least this can be simplified by converting sparc to use
the same interface as the others.
The only difference between the two is the device-specific offset that gets
added to or subtracted from vma->vm_pgoff.
Change the only caller of pci_mmap_page_range() in common code to subtract
this offset and call the modern interface, while adding it back in the
sparc implementation to preserve the existing behavior.
This removes the complexities of the dual interfaces from the common code,
and keeps it all specific to the sparc architecture code. According to
David Miller, the sparc code lets user space poke into the VGA I/O port
registers by mmapping the I/O space of the parent bridge device, which is
something that the generic pci_mmap_resource_range() code apparently does
not.

The bindings already offer a brcm,ccode-map property to describe the
mapping between the kernel's ISO3166 alpha 2 country code string and the
firmware's country code string and revision number. This is a
board-specific property and determined by the CLM blob firmware provided
by the hardware vendor.
However, in some cases the firmware will also use ISO3166 country codes
internally, and the revision will always be zero. This implies a trivial
mapping: cc -> { cc, 0 }.
For such cases, add an optional property brcm,ccode-map-trivial which
obviates the need to describe every trivial country code mapping in the
device tree with the existing brcm,ccode-map property. The new property
is subordinate to the more explicit brcm,ccode-map property.

change, led to a late rc6 fix being required. In order to avoid this
in the future we should document some expectations around
linux-firmware.
I was originally going to write this for drm, but it seems quite generic
advice.

While it's a lot of text, it always helps to keep it up to date when
it's by the source. (And not in a separate file.)
The documentation tooling also makes sure that all members of the
structure are documented. (If not, it complains loudly.)
Finally, there needs to be no comments inlined in the structure, so they
are dropped as they are superfluous now.
The compilation time of this header (tested with serial_core.c) didn't
change in my testing at all.

30312730bd ("cgroup: Add "no" prefixed mount options") added "no" prefixed
mount options to allow turning them off and 6a010a49b6 ("cgroup: Make
!percpu threadgroup_rwsem operations optional") added one more "no" prefixed
mount option. However, Michal pointed out that the "no" prefixed options
aren't necessary in allowing mount options to be turned off:
# grep group /proc/mounts
cgroup2 /sys/fs/cgroup cgroup2 rw,nosuid,nodev,relatime,nsdelegate,memory_recursiveprot 0 0
# mount -o remount,nsdelegate,memory_recursiveprot none /sys/fs/cgroup
# grep cgroup /proc/mounts
cgroup2 /sys/fs/cgroup cgroup2 rw,relatime,nsdelegate,memory_recursiveprot 0 0
Note that this is different from the remount behavior when the mount(1) is
invoked without the device argument - "none":
# grep cgroup /proc/mounts
cgroup2 /sys/fs/cgroup cgroup2 rw,nosuid,nodev,noexec,relatime,nsdelegate,memory_recursiveprot 0 0
# mount -o remount,nsdelegate,memory_recursiveprot /sys/fs/cgroup
# grep cgroup /proc/mounts
cgroup2 /sys/fs/cgroup cgroup2 rw,nosuid,nodev,noexec,relatime,nsdelegate,memory_recursiveprot 0 0
While a bit confusing, given that there is a way to turn off the options,
there's no reason to have the explicit "no" prefixed options. Let's remove
them.

Add DT schema documentation for the STM32G0 Type-C PD (Power Delivery)
controller.
STM32G0 provides an integrated USB Type-C and power delivery interface.
It can be programmed with a firmware to handle UCSI protocol over I2C
interface. A GPIO is used as an interrupt line.
It may be used as a wakeup source, so use optional "wakeup-source" and
"power-domains" properties to support wakeup.
The firmware itself may be flashed or later updated (optional). Choice is
let to the application to allow firmware update. A default firmware could
be already programmed in production and be customized (to not allow it).
So the firmware-name is made optional to represent this option.

During an LPM, while the memory transfer is in progress on the arrival
side, some latencies are generated when accessing not yet transferred
pages on the arrival side. Thus, the NMI watchdog may be triggered too
frequently, which increases the risk to hit an NMI interrupt in a bad
place in the kernel, leading to a kernel panic.
Disabling the Hard Lockup Watchdog until the memory transfer could be a
too strong work around, some users would want this timeout to be
eventually triggered if the system is hanging even during an LPM.
Introduce a new sysctl variable nmi_watchdog_factor. It allows to apply
a factor to the NMI watchdog timeout during an LPM. Just before the CPUs
are stopped for the switchover sequence, the NMI watchdog timer is set
to watchdog_thresh + factor%
A value of 0 has no effect. The default value is 200, meaning that the
NMI watchdog is set to 30s during LPM (based on a 10s watchdog_thresh
value). Once the memory transfer is achieved, the factor is reset to 0.
Setting this value to a high number is like disabling the NMI watchdog
during an LPM.

Extend interrupts and pinctrls for SDIO wakeup interrupt feature.
This feature allow SDIO devices alarm asynchronous interrupt to host
even when host stop providing clock to SDIO card. An extra wakeup
interrupt and pinctrl states for SDIO DAT1 pin state switching are
required in this scenario.

them and include instead in the SPI controller bindings. The controller
bindings will provide CPHA/CPOL type validation and one place for

Most of the callers of vfio_pin_pages() want "struct page *" and the
low-level mm code to pin pages returns a list of "struct page *" too.
So there's no gain in converting "struct page *" to PFN in between.
Replace the output parameter "phys_pfn" list with a "pages" list, to
simplify callers. This also allows us to replace the vfio_iommu_type1
implementation with a more efficient one.
And drop the pfn_valid check in the gvt code, as there is no need to
do such a check at a page-backed struct page pointer.
For now, also update vfio_iommu_type1 to fit this new parameter too.

The vfio_pin/unpin_pages() so far accepted arrays of PFNs of user IOVA.
Among all three callers, there was only one caller possibly passing in
a non-contiguous PFN list, which is now ensured to have contiguous PFN
inputs too.
Pass in the starting address with "iova" alone to simplify things, so
callers no longer need to maintain a PFN list or to pin/unpin one page
at a time. This also allows VFIO to use more efficient implementations
of pin/unpin_pages.
For now, also update vfio_iommu_type1 to fit this new parameter too,
while keeping its input intact (being user_iova) since we don't want
to spend too much effort swapping its parameters and local variables
at that level.

After all the soft validation of the region has completed, convey the
region configuration to hardware while being careful to commit decoders
in specification mandated order. In addition to programming the endpoint
decoder base-address, interleave ways and granularity, the switch
decoder target lists are also established.
While the kernel can enforce spec-mandated commit order, it can not
enforce spec-mandated reset order. For example, the kernel can't stop
someone from removing an endpoint device that is occupying decoderN in a
switch decoder where decoderN+1 is also committed. To reset decoderN,
decoderN+1 must be torn down first. That "tear down the world"
implementation is saved for a follow-on patch.
Callback operations are provided for the 'commit' and 'reset'
operations. While those callbacks may prove useful for CXL accelerators
(Type-2 devices with memory) the primary motivation is to enable a
simple way for cxl_test to intercept those operations.

The region provisioning process involves allocating DPA to a set of
endpoint decoders, and HPA plus the region geometry to a region device.
Then the decoder is assigned to the region. At this point several
validation steps can be performed to validate that the decoder is
suitable to participate in the region.

After a region's interleave parameters (ways and granularity) are set,
add a way for regions to allocate HPA (host physical address space) from
the free capacity in their parent root-decoder. The allocator for this
capacity reuses the 'struct resource' based allocator used for
CONFIG_DEVICE_PRIVATE.
Once the tuple of "ways, granularity, [uuid], and size" is set the
region configuration transitions to the CXL_CONFIG_INTERLEAVE_ACTIVE
state which is a precursor to allowing endpoint decoders to be added to
a region.

Currently when creating a specific group of trace events,

which means user must enter EVENT name, one example is:
echo 'p:usb_gadget/config_usb_cfg_link config_usb_cfg_link $arg1' >> kprobe_events
It is not simple if there are too many entries because the event name is
the same as symbol name.
This change allows user to specify no EVENT name, format changed as:
p:GRP/ [MOD:]KSYM[+OFFS]|KADDR [FETCHARGS]
It will generate event name automatically and one example is:
echo 'p:usb_gadget/ config_usb_cfg_link $arg1' >> kprobe_events.

3942a9bd7b ("locking, rcu, cgroup: Avoid synchronize_sched() in
__cgroup_procs_write()") disabled percpu operations on threadgroup_rwsem
because the impiled synchronize_rcu() on write locking was pushing up the
latencies too much for android which constantly moves processes between
cgroups.
This makes the hotter paths - fork and exit - slower as they're always
forced into the slow path. There is no reason to force this on everyone
especially given that more common static usage pattern can now completely
avoid write-locking the rwsem. Write-locking is elided when turning on and
off controllers on empty sub-trees and CLONE_INTO_CGROUP enables seeding a
cgroup without grabbing the rwsem.
Restore the default percpu operations and introduce the mount option
"favordynmods" and config option CGROUP_FAVOR_DYNMODS for users who need
lower latencies for the dynamic operations.

There's only one caller that checks its return value with a WARN_ON_ONCE,
while all other callers don't check the return value at all. Above that,
an undo function should not fail. So, simplify the API to return void by
embedding similar WARN_ONs.
Also for users to pinpoint which condition fails, separate WARN_ON lines,
yet remove the "driver->ops->unpin_pages" check, since it's unreasonable
for callers to unpin on something totally random that wasn't even pinned.
And remove NULL pointer checks for they would trigger oops vs. warnings.
Note that npage is already validated in the vfio core, thus drop the same
check in the type1 code.

This pull request contains a pair of commits that fix 282d8998e9 ("srcu:
Prevent expedited GPs and blocking readers from consuming CPU"), which
was itself a fix to an SRCU expedited grace-period problem that could
prevent kernel live patching (KLP) from completing. That SRCU fix for
KLP introduced large (as in minutes) boot-time delays to embedded Linux
kernels running on qemu/KVM. These delays were due to the emulation of
certain MMIO operations controlling memory layout, which were emulated
with one expedited grace period per access. Common configurations
required thousands of boot-time MMIO accesses, and thus thousands of
boot-time expedited SRCU grace periods.
In these configurations, the occasional sleeps that allowed KLP to proceed
caused excessive boot delays. These commits preserve enough sleeps to
permit KLP to proceed, but few enough that the virtual embedded kernels
still boot reasonably quickly.
This represents a regression introduced in the v5.19 merge window,
and the bug is causing significant inconvenience, hence this pull request.
