Arnd Bergmann 1cb00f8c3b Qualcomm ARM64 DT updates for v5.8
For SDM845 this defines the IPA network accelerator and the CCI camera
 control bus, it defines the required UFS reset and adds WiFi for the
 Lenovo Yoga C630 and defines GPIO pin names and adds OV8856 and OC7251
 camera nodes for DB845c.
 
 For SC7180 it adds GPU support, defines the modem remoteproc, adds the
 IPA network accelerator, Coresight and ETM support, adds cpuidle low
 power states and updates the CPUs' compatible.
 
 For SM8250 it adds regulators from the PM8150, PM8150L and PM8009 and
 adds voltage corners, it defines the nodes for UFS PHY and controller
 and finally corrects a typo in the PDC node to make SPMI functional.
 
 For MSM8916 I2C1 and I2C5 are defined, a node for the CCI camera control
 interface bus is added and Coresight is disabled by default to match
 some product configurations. The Samsung A3U gained display support and
 Samsung A5U gained touchscreen support.
 
 MSM8996 now property describes the power supply chain for the GPU, the
 CCI camera control interface bus is added and the DB820c has the
 regulators of the secondary PMIC defined.
 
 For QCS404 USB PHYs and controllers are defined and wired up for the
 EVB.
 
 SDM630/SDM660 platform support is added and the Xiaomi Redmi Note 7
 defined.
 
 It also contains a number of changes throughout to improve DT binding
 compliance.

Double lock feature can have the following possible values.

0b1111 - Double lock not implemented

But in case of a conflict the safe value should be 0b1111. Hence this must
be a signed feature instead. Also change FTR_EXACT to FTR_LOWER_SAFE. While
here, fix the erroneous bit width value from 28 to 4.

Will Deacon a4eb355a3f arm64: vdso: Fix CFI directives in sigreturn trampoline
Daniel reports that the .cfi_startproc is misplaced for the sigreturn
trampoline, which causes LLVM's unwinder to misbehave:

  | I run into this with LLVM’s unwinder.
  | This combination was always broken.

This prompted Dave to question our use of CFI directives more generally,
and I ended up going down a rabbit hole trying to figure out how this
very poorly documented stuff gets used.

Move the CFI directives so that the "mysterious NOP" is included in
the .cfi_{start,end}proc block and add a bunch of comments so that I
can save myself another headache in future.

Will Deacon 9a96428557 arm64: vdso: Don't prefix sigreturn trampoline with a BTI C instruction
For better or worse, GDB relies on the exact instruction sequence in the
VDSO sigreturn trampoline in order to unwind from signals correctly.
Commit c91db232da ("arm64: vdso: Convert to modern assembler annotations")
unfortunately added a BTI C instruction to the start of __kernel_rt_sigreturn,
which breaks this check. Thankfully, it's also not required, since the
trampoline is called from a RET instruction when returning from the signal
handler

Remove the unnecessary BTI C instruction from __kernel_rt_sigreturn,
and do the same for the 32-bit VDSO as well for good measure.

Jon Hunter bba25915b1 arm64: tegra: Fix ethernet phy-mode for Jetson Xavier
The 'phy-mode' property is currently defined as 'rgmii' for Jetson
Xavier. This indicates that the RGMII RX and TX delays are set by the
MAC and the internal delays set by the PHY are not used.

If the Marvell PHY driver is enabled, such that it is used and not the
generic PHY, ethernet failures are seen (DHCP is failing to obtain an
IP address) and this is caused because the Marvell PHY driver is
disabling the internal RX and TX delays. For Jetson Xavier the internal
PHY RX and TX delay should be used and so fix this by setting the
'phy-mode' to 'rgmii-id' and not 'rgmii'.

Keno Fischer 1cf6022bd9 arm64: Fix PTRACE_SYSEMU semantics
Quoth the man page:
```
       If the tracee was restarted by PTRACE_SYSCALL or PTRACE_SYSEMU, the
       tracee enters syscall-enter-stop just prior to entering any system
       call (which will not be executed if the restart was using
       PTRACE_SYSEMU, regardless of any change made to registers at this
       point or how the tracee is restarted after this stop).
```

The parenthetical comment is currently true on x86 and powerpc,
but not currently true on arm64. arm64 re-checks the _TIF_SYSCALL_EMU
flag after the syscall entry ptrace stop. However, at this point,
it reflects which method was used to re-start the syscall
at the entry stop, rather than the method that was used to reach it.
Fix that by recording the original flag before performing the ptrace
stop, bringing the behavior in line with documentation and x86/powerpc.

James Morse 8fcc4ae6fa arm64: acpi: Make apei_claim_sea() synchronise with APEI's irq work
APEI is unable to do all of its error handling work in nmi-context, so
it defers non-fatal work onto the irq_work queue. arch_irq_work_raise()
sends an IPI to the calling cpu, but this is not guaranteed to be taken
before returning to user-space.

Unless the exception interrupted a context with irqs-masked,
irq_work_run() can run immediately. Otherwise return -EINPROGRESS to
indicate ghes_notify_sea() found some work to do, but it hasn't
finished yet.

With this apei_claim_sea() returning '0' means this external-abort was
also notification of a firmware-first RAS error, and that APEI has
processed the CPER records.

Frederic Weisbecker 28f6bf9e24 arm64: Prepare arch_nmi_enter() for recursion
When using nmi_enter() recursively, arch_nmi_enter() must also be recursion
safe. In particular, it must be ensured that HCR_TGE is always set while in
NMI context when in HYP mode, and be restored to it's former state when
done.

The current code fails this when interleaved wrong. Notably it overwrites
the original hcr state on nesting.

Fix these errors with help of the following rules:

1: Add nodename in the preferred form.

2: Always add a label that ends with '_led' to prevent conflicts
   with other labels such as 'power' and 'mmc'

3: If leds need pinctrl add a label that ends with '_led_pin'
   also to prevent conflicts with other labels.

patternProperties:
  # The first form is preferred, but fall back to just 'led'

Douglas Anderson b322c65f8c arm64: Call debug_traps_init() from trap_init() to help early kgdb
A new kgdb feature will soon land (kgdb_earlycon) that lets us run
kgdb much earlier.  In order for everything to work properly it's
important that the break hook is setup by the time we process
"kgdbwait".

Right now the break hook is setup in debug_traps_init() and that's
called from arch_initcall().  That's a bit too late since
kgdb_earlycon really needs things to be setup by the time the system
calls dbg_late_init().

We could fix this by adding call_break_hook() into early_brk64() and
that works fine.  However, it's a little ugly.  Instead, let's just
add a call to debug_traps_init() straight from trap_init().  There's
already a documented dependency between trap_init() and
debug_traps_init() and this makes the dependency more obvious rather
than just relying on a comment.

NOTE: this solution isn't early enough to let us select the
"ARCH_HAS_EARLY_DEBUG" KConfig option that is introduced by the
kgdb_earlycon patch series.  That would only be set if we could do
breakpoints when early params are parsed.  This patch only enables
"late early" breakpoints, AKA breakpoints when dbg_late_init() is
called.  It's expected that this should be fine for most people.

It should also be noted that if you crash you can still end up in kgdb
earlier than debug_traps_init().  Since you don't need breakpoints to
debug a crash that's fine.

Will Deacon 88485be531 scs: Move scs_overflow_check() out of architecture code
There is nothing architecture-specific about scs_overflow_check() as
it's just a trivial wrapper around scs_corrupted().

For parity with task_stack_end_corrupted(), rename scs_corrupted() to
task_scs_end_corrupted() and call it from schedule_debug() when
CONFIG_SCHED_STACK_END_CHECK_is enabled, which better reflects its
purpose as a debug feature to catch inadvertent overflow of the SCS.
Finally, remove the unused scs_overflow_check() function entirely.

This has absolutely no impact on architectures that do not support SCS
(currently arm64 only).

Marek Behún 7158780169 arm64: dts: marvell: armada-37xx: Set pcie_reset_pin to gpio function
We found out that we are unable to control the PERST# signal via the
default pin dedicated to be PERST# pin (GPIO2[3] pin) on A3700 SOC when
this pin is in EP_PCIE1_Resetn mode. There is a register in the PCIe
register space called PERSTN_GPIO_EN (D0088004[3]), but changing the
value of this register does not change the pin output when measuring
with voltmeter.

We do not know if this is a bug in the SOC, or if it works only when
PCIe controller is in a certain state.

Commit f4c7d053d7 ("PCI: aardvark: Wait for endpoint to be ready
before training link") says that when this pin changes pinctrl mode
from EP_PCIE1_Resetn to GPIO, the PERST# signal is asserted for a brief
moment.

So currently the situation is that on A3700 boards the PERST# signal is
asserted in U-Boot (because the code in U-Boot issues reset via this pin
via GPIO mode), and then in Linux by the obscure and undocumented
mechanism described by the above mentioned commit.

We want to issue PERST# signal in a known way, therefore this patch
changes the pcie_reset_pin function from "pcie" to "gpio" and adds the
reset-gpios property to the PCIe node in device tree files of
EspressoBin and Armada 3720 Dev Board (Turris Mox device tree already
has this property and uDPU does not have a PCIe port).

Add I2C support for Mediatek MT6797 SoC. There are a total of 8 I2C
controllers in this SoC (2 being shared) and they are same as the
controllers present in MT6577 SoC. Hence, the driver support is added with
DT fallback method.

As per the datasheet, there are controllers with _imm prefix like i2c2_imm
and i2c3_imm. These appears to be in different memory regions but sharing
the same pins with i2c2 and i2c3 respectively. Since there is no clear
evidence of what they really are, I've adapted the numbering/naming scheme
from the downstream code by Mediatek.

Marc Zyngier 5107000faa KVM: arm64: Make KVM_CAP_MAX_VCPUS compatible with the selected GIC version
KVM_CAP_MAX_VCPUS always return the maximum possible number of
VCPUs, irrespective of the selected interrupt controller. This
is pretty misleading for userspace that selects a GICv2 on a GICv3
system that supports v2 compat: It always gets a maximum of 512
VCPUs, even if the effective limit is 8. The 9th VCPU will fail
to be created, which is unexpected as far as userspace is concerned.

Fortunately, we already have the right information stashed in the
kvm structure, and we can return it as requested.

Keqian Zhu c862626e19 KVM: arm64: Support enabling dirty log gradually in small chunks
There is already support of enabling dirty log gradually in small chunks
for x86 in commit 3c9bd4006b ("KVM: x86: enable dirty log gradually in
small chunks"). This adds support for arm64.

x86 still writes protect all huge pages when DIRTY_LOG_INITIALLY_ALL_SET
is enabled. However, for arm64, both huge pages and normal pages can be
write protected gradually by userspace.

Under the Huawei Kunpeng 920 2.6GHz platform, I did some tests on 128G
Linux VMs with different page size. The memory pressure is 127G in each
case. The time taken of memory_global_dirty_log_start in QEMU is listed
below:

Page Size      Before    After Optimization
  4K            650ms         1.8ms
  2M             4ms          1.8ms
  1G             2ms          1.8ms

Besides the time reduction, the biggest improvement is that we will minimize
the performance side effect (because of dissolving huge pages and marking
memslots dirty) on guest after enabling dirty log.

Suzuki K Poulose 0529c90212 KVM: arm64: Unify handling THP backed host memory
We support mapping host memory backed by PMD transparent hugepages
at stage2 as huge pages. However the checks are now spread across
two different places. Let us unify the handling of the THPs to
keep the code cleaner (and future proof for PUD THP support).
This patch moves transparent_hugepage_adjust() closer to the caller
to avoid a forward declaration for fault_supports_stage2_huge_mappings().

Also, since we already handle the case where the host VA and the guest
PA may not be aligned, the explicit VM_BUG_ON() is not required.

Zenghui Yu 892713e97c KVM: arm64: Sidestep stage2_unmap_vm() on vcpu reset when S2FWB is supported
stage2_unmap_vm() was introduced to unmap user RAM region in the stage2
page table to make the caches coherent. E.g., a guest reboot with stage1
MMU disabled will access memory using non-cacheable attributes. If the
RAM and caches are not coherent at this stage, some evicted dirty cache
line may go and corrupt guest data in RAM.

Since ARMv8.4, S2FWB feature is mandatory and KVM will take advantage
of it to configure the stage2 page table and the attributes of memory
access. So we ensure that guests always access memory using cacheable
attributes and thus, the caches always be coherent.

So on CPUs that support S2FWB, we can safely reset the vcpu without a
heavy stage2 unmapping.

David Matlack cb953129bf kvm: add halt-polling cpu usage stats
Two new stats for exposing halt-polling cpu usage:
halt_poll_success_ns
halt_poll_fail_ns

Thus sum of these 2 stats is the total cpu time spent polling. "success"
means the VCPU polled until a virtual interrupt was delivered. "fail"
means the VCPU had to schedule out (either because the maximum poll time
was reached or it needed to yield the CPU).

To avoid touching every arch's kvm_vcpu_stat struct, only update and
export halt-polling cpu usage stats if we're on x86.

Exporting cpu usage as a u64 and in nanoseconds means we will overflow at
~500 years, which seems reasonably large.

Daniel Borkmann 0ebeea8ca8 bpf: Restrict bpf_probe_read{, str}() only to archs where they work
Given the legacy bpf_probe_read{,str}() BPF helpers are broken on archs
with overlapping address ranges, we should really take the next step to
disable them from BPF use there.

To generally fix the situation, we've recently added new helper variants
bpf_probe_read_{user,kernel}() and bpf_probe_read_{user,kernel}_str().
For details on them, see 6ae08ae3de ("bpf: Add probe_read_{user, kernel}
and probe_read_{user,kernel}_str helpers").

Given bpf_probe_read{,str}() have been around for ~5 years by now, there
are plenty of users at least on x86 still relying on them today, so we
cannot remove them entirely w/o breaking the BPF tracing ecosystem.

However, their use should be restricted to archs with non-overlapping
address ranges where they are working in their current form. Therefore,
move this behind a CONFIG_ARCH_HAS_NON_OVERLAPPING_ADDRESS_SPACE and
have x86, arm64, arm select it (other archs supporting it can follow-up
on it as well).

For the remaining archs, they can workaround easily by relying on the
feature probe from bpftool which spills out defines that can be used out
of BPF C code to implement the drop-in replacement for old/new kernels
via: bpftool feature probe macro

Miklos Szeredi c8ffd8bcdd vfs: add faccessat2 syscall
POSIX defines faccessat() as having a fourth "flags" argument, while the
linux syscall doesn't have it.  Glibc tries to emulate AT_EACCESS and
AT_SYMLINK_NOFOLLOW, but AT_EACCESS emulation is broken.

Add a new faccessat(2) syscall with the added flags argument and implement
both flags.

The value of AT_EACCESS is defined in glibc headers to be the same as
AT_REMOVEDIR.  Use this value for the kernel interface as well, together
with the explanatory comment.

Also add AT_EMPTY_PATH support, which is not documented by POSIX, but can
be useful and is trivial to implement.

Bjorn Andersson 1cacdf5d3b arm64: dts: qcom: db820c: Fix invalid pm8994 supplies
It's uncertain where the "vreg_s8a_l3a_input" comes from, but the supply
for VDD_L3_L11 on PM8994 should be VREG_S3A_1P3, so correct this - and
drop the vreg_s8a_l3a_input.

Michael Srba b3d6fd8f25 arm64: dts: qcom: msm8916: Disable coresight by default
On some msm8916 devices, attempts at initializing coresight cause the boot to
fail. This was fixed by disabling the coresight-related nodes in the board dts
files. However, a cleaner approach was chosen for fixing the same issue on
msm8998: disabling coresight by default, and enabling it in board dts files
where desired.

This patch implements the same solution for msm8916, removes now redundant
overwrites in board specific dts files and and enables coresight in db410c's
board dts in order to keep the current behavior.

Fabio Estevam e98ad55989 arm64: dts: imx8qxp-mek: Do not use underscore in node name
Underscores are not recommended to be used in node names, so change
the pinctrl IO expander node name.

This change also makes the pinctrl node names to follow the convention
used by other pinctrl group names.
