Okay, so... this one is interesting. RGB LEDs are very common, and we
need to have some kind of support for them. Multicolor is for
arbitrary set of LEDs in one package, RGB is for LEDs that can produce
full range of colors. We do not have real multicolor LED that is not
RGB in the pipeline, so that one is disabled for now.
You can expect this saga to continue with next pull requests.

====================
misc bug fixes for the hso driver
1. Code reuse led to an unregistration of a net driver that has not been
registered
2. The kernel complains generically if kmalloc with GFP_KERNEL fails
3. A race that can lead to an URB that is in use being reused or
a use after free
====================
Signed-off-by: David S. Miller <davem@davemloft.net>
This check an inherent race. It opens a race where
an error code has already been set or cleared yet
the URB has not been given back. We cannot do
such an optimization and must unlink unconditionally.

If this fails, kmalloc() will print a report including
a stack trace. There is no need for a separate complaint.

The driver tries to reuse code for disconnect in case
of a failed probe.
If resources need to be freed after an error in probe, the
netdev must not be freed because it has never been registered.
Fix it by telling the helper which path we are in.

Before switch from discontigmem to sparsemem, there always was
CONFIG_NEED_MULTIPLE_NODES=y because it was selected by DISCONTIGMEM.
Without DISCONTIGMEM it is possible to have SPARSEMEM without NUMA for
SGI_IP27 and as many things there rely on custom node definition, the
build breaks.
As Thomas noted "... there are right now too many places in IP27 code,
which assumes NUMA enabled", the simplest solution would be to always
enable NUMA for SGI-IP27 builds.

This series adds reporting of the page table order from hmm_range_fault()
and some optimization of migrate_vma():
- Report the size of the page table mapping out of hmm_range_fault(). This
makes it easier to establish a large/huge/etc mapping in the device's
page table.
- Allow devices to ignore the invalidations during migration in cases
where the migration is not going to change pages. For instance migrating
pages to a device does not require the device to invalidate pages
already in the device.
- Update nouveau and hmm_tests to use the above

- Split out the sysfs code into its own file.
- Split out the character device code into its own file, then
make a set of refactorings and improvements to this code.
We are setting the stage to revamp the userspace API a bit
in the next cycle.
- Fix a whole slew of kerneldoc that was wrong or missing.
New drivers:
- The PCA953x driver now supports the PCAL9535.
Driver improvements:
- A host of incremental modernizations and improvements to the
PCA953x driver.
- Incremental improvements to the Xilinx Zynq driver.
- Some improvements to the GPIO aggregator driver.
- I ran all over the place switching all threaded and other
drivers requesting their own IRQ while using the core
GPIO IRQ helpers to pass the GPIO irq chip as a template
instead of calling the explicit set-up functions. Next merge
window we may retire the old code altogether.

Merge tag 'gpio-v5.9-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio
Pull GPIO updates from Linus Walleij:
"This is the bulk of GPIO changes for the v5.9 kernel cycle.
There is nothing too exciting in it, but a new macro that fixes a
build failure on a minor ARM32 platform that appeared yesterday is
part of it so we better merge it.
Core changes:
- Introduce the for_each_requested_gpio() macro to help in dependent
code all over the place. Also patch a few locations to use it while
we are at it.
- Split out the sysfs code into its own file.
- Split out the character device code into its own file, then make a
set of refactorings and improvements to this code. We are setting
the stage to revamp the userspace API a bit in the next cycle.
- Fix a whole slew of kerneldoc that was wrong or missing.
New drivers:
- The PCA953x driver now supports the PCAL9535.
Driver improvements:
- A host of incremental modernizations and improvements to the
PCA953x driver.
- Incremental improvements to the Xilinx Zynq driver.
- Some improvements to the GPIO aggregator driver.
- I ran all over the place switching all threaded and other drivers
requesting their own IRQ while using the core GPIO IRQ helpers to
pass the GPIO irq chip as a template instead of calling the
explicit set-up functions. Next merge window we may retire the old
code altogether"

The msg_zerocopy test pins the sender and receiver threads to separate
cores to reduce variance between runs.
But it hardcodes the cores and skips core 0, so it fails on machines
with the selected cores offline, or simply fewer cores.
The test mainly gives code coverage in automated runs. The throughput
of zerocopy ('-z') and non-zerocopy runs is logged for manual
inspection.
Continue even when sched_setaffinity fails. Just log to warn anyone
interpreting the data.

selftests: rtnetlink: Fix for false-negative return values
This patchset will address the false-negative return value issue
caused by the following:
1. The return value "ret" in this script will be reset to 0 from
the beginning of each sub-test in rtnetlink.sh, therefore this
rtnetlink test will always pass if the last sub-test has passed.
2. The test result from two sub-tests in kci_test_encap() were not
being processed, thus they will not affect the final test result
of this test.

kci_test_encap() is actually composed by two different sub-tests,
kci_test_encap_vxlan() and kci_test_encap_fou()
Therefore we should check the test result of these two in
kci_test_encap() to let the script be aware of the pass / fail status.
Otherwise it will generate false-negative result like below:

Although we can detect the chip revision 100% at runtime, it is useful
to specify it in the device tree compatible string too, because
otherwise there would be no way to assess the correctness of device tree
bindings statically, without booting a board (only some switch versions
have internal RGMII delays and/or an SGMII port).
But for testing the P/Q/R/S support, what I have is a reworked board
with the SJA1105T replaced by a pin-compatible SJA1105Q, and I don't
want to keep a separate device tree blob just for this one-off board.
Since just the chip has been replaced, its RGMII delay setup is
inherently the same (meaning: delays added by the PHY on the slave
ports, and by PCB traces on the fixed-link CPU port).
For this board, I'd rather have the driver shout at me, but go ahead and
use what it found even if it doesn't match what it's been told is there.
[ 2.970826] sja1105 spi0.1: Device tree specifies chip SJA1105T but found SJA1105Q, please fix it!

Without ub->ifindex set for ipv6 address in tipc_udp_enable(),

never be created.
So fix it by getting the right netdev and setting ub->ifindex,

This reverts commit 71130f2997.
In commit 71130f2997 ("vxlan: fix tos value before xmit") we want to
make sure the tos value are filtered by RT_TOS() based on RFC1349.
0 1 2 3 4 5 6 7
+-----+-----+-----+-----+-----+-----+-----+-----+
| PRECEDENCE | TOS | MBZ |
+-----+-----+-----+-----+-----+-----+-----+-----+
But RFC1349 has been obsoleted by RFC2474. The new DSCP field defined like
0 1 2 3 4 5 6 7
+-----+-----+-----+-----+-----+-----+-----+-----+
| DS FIELD, DSCP | ECN FIELD |
+-----+-----+-----+-----+-----+-----+-----+-----+
So with
IPTOS_TOS_MASK 0x1E
RT_TOS(tos) ((tos)&IPTOS_TOS_MASK)
the first 3 bits DSCP info will get lost.
To take all the DSCP info in xmit, we should revert the patch and just push
all tos bits to ip_tunnel_ecn_encap(), which will handling ECN field later.

"Biggest" thing in here is the device link exposure in sysfs, to help
to tame the madness that is SoC device tree representations and driver
interactions with it.
Other stuff in here that is interesting is:
- device probe log helper so that drivers can report problems in
a unified way easier.
- devres functions added
- DEVICE_ATTR_ADMIN_* macro added to make it harder to write
incorrect sysfs file permissions
- documentation cleanups
- ability for debugfs to be present in the kernel, yet not
exposed to userspace. Needed for systems that want it
enabled, but do not trust users, so they can still use some
kernel functions that were otherwise disabled.
- other minor fixes and cleanups

syzbot has revealed that the "phylink" keyword exists in non-phylink
related contexts in the bluetooth stack. To avoid receiving
inappropriate notifications, change the keyword matching regexp to
something which avoids this, while still allowing changes to networking
drivers that make use of phylink to be detected.

- Adds a generic kunit_resource API extending it to support
resources that are passed in to kunit in addition kunit
allocated resources. In addition, KUnit resources are now
refcounted to avoid passed in resources being released while
in use by kunit.
- Add support for named resources.

this has been brought into a shape which is maintainable and actually
works.
This final version was done by Sasha Levin who took it up after Intel
dropped the ball. Sasha discovered that the SGX (sic!) offerings out there
ship rogue kernel modules enabling FSGSBASE behind the kernels back which
opens an instantanious unpriviledged root hole.
The FSGSBASE instructions provide a considerable speedup of the context
switch path and enable user space to write GSBASE without kernel
interaction. This enablement requires careful handling of the exception
entries which go through the paranoid entry path as they cannot longer rely
on the assumption that user GSBASE is positive (as enforced via prctl() on
non FSGSBASE enabled systemn). All other entries (syscalls, interrupts and
exceptions) can still just utilize SWAPGS unconditionally when the entry
comes from user space. Converting these entries to use FSGSBASE has no
benefit as SWAPGS is only marginally slower than WRGSBASE and locating and
retrieving the kernel GSBASE value is not a free operation either. The real
benefit of RD/WRGSBASE is the avoidance of the MSR reads and writes.
The changes come with appropriate selftests and have held up in field
testing against the (sanitized) Graphene-SGX driver.

Pull x86 conversion to generic entry code from Thomas Gleixner:
"The conversion of X86 syscall, interrupt and exception entry/exit
handling to the generic code.
Pretty much a straight-forward 1:1 conversion plus the consolidation
of the KVM handling of pending work before entering guest mode"
* tag 'x86-entry-2020-08-04' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
x86/kvm: Use __xfer_to_guest_mode_work_pending() in kvm_run_vcpu()
x86/kvm: Use generic xfer to guest work function
x86/entry: Cleanup idtentry_enter/exit
x86/entry: Use generic interrupt entry/exit code
x86/entry: Cleanup idtentry_entry/exit_user
x86/entry: Use generic syscall exit functionality
x86/entry: Use generic syscall entry function
x86/ptrace: Provide pt_regs helper for entry/exit
x86/entry: Move user return notifier out of loop
x86/entry: Consolidate 32/64 bit syscall entry
x86/entry: Consolidate check_user_regs()
x86: Correct noinstr qualifiers
x86/idtentry: Remove stale comment
entry/exit functionality based on the recent X86 effort to ensure
correctness of entry/exit vs. RCU and instrumentation.
As this functionality and the required entry/exit sequences are not
architecture specific, sharing them allows other architectures to benefit
instead of copying the same code over and over again.
This branch was kept standalone to allow others to work on it. The
conversion of x86 comes in a seperate pull request which obviously is based
on this branch.

- Prevent unnecessary timer softirq invocations by extending the tracking

functionality. The tracking overhead at enqueue time is within the
noise, but on sensitive workloads the avoidance of the soft interrupt
invocation is a measurable improvement.

If the accelerated networking SRIOV VF device has lost carrier
use the synthetic network device which is available as backup
path. This is a rare case since if VF link goes down, normally
the VMBus device will also loose external connectivity as well.
But if the communication is between two VM's on the same host
the VMBus device will still work.
