Chao Yu fa4320cefb f2fs: move ioctl interface definitions to separated file
Like other filesystem does, we introduce a new file f2fs.h in path of
include/uapi/linux/, and move f2fs-specified ioctl interface definitions
to that file, after then, in order to use those definitions, userspace
developer only need to include the new header file rather than
copy & paste definitions from fs/f2fs/f2fs.h.

llseek() reports invalid block address access, the root cause is if
file has inline data, f2fs_seek_block() will access inline data regard
as block address index in inode block, which should be wrong, fix it.

Linus Torvalds 31f020064f Char/Misc fixes/removals for 5.10-rc2
Here's some small fixes for 5.10-rc2 and a big driver removal.
 
 The fixes are for some reported issues in the interconnect and coresight
 drivers, nothing major.
 
 The "big" driver removal is the MIC drivers have been asked to be
 removed as the hardware never shipped and Intel no longer wants to
 maintain something that no one can use.  This is welcomed by many as the
 DMA usage of these drivers was "interesting" and the security people
 were starting to question some issues that were starting to be found in
 the codebase.
 
 Note, one of the subsystems for this driver, the "VOP" code, will
 probably come back in future kernel versions as it was looking to
 potentially solve some PCIe virtualization issues that a number of other
 vendors were wanting to solve.  But as-is, this codebase didn't work for
 anyone else so no actual functionality is being removed.
 
 All of these have been in linux-next with no reported issues.

Linus Torvalds 9c75b68b91 Driver core / Documentation fixes for 5.10-rc2
Here is one tiny debugfs change to fix up an API where the last user was
 successfully fixed up in 5.10-rc1 (so it couldn't be merged earlier),
 and a much larger Documentation/ABI/ update to the files so they can be
 automatically parsed by our tools.
 
 The Documentation/ABI/ updates are just formatting issues, small ones to
 bring the files into parsable format, and have been acked by numerous
 subsystem maintainers and the documentation maintainer.  I figured it
 was good to get this into 5.10-rc2 to help with the merge issues that
 would arise if these were to stick in linux-next until 5.11-rc1.
 
 The debugfs change has been in linux-next for a long time, and the

Vitaly Kuznetsov 064eedf2c5 KVM: VMX: eVMCS: make evmcs_sanitize_exec_ctrls() work again
It was noticed that evmcs_sanitize_exec_ctrls() is not being executed
nowadays despite the code checking 'enable_evmcs' static key looking
correct. Turns out, static key magic doesn't work in '__init' section
(and it is unclear when things changed) but setup_vmcs_config() is called
only once per CPU so we don't really need it to. Switch to checking
'enlightened_vmcs' instead, it is supposed to be in sync with
'enable_evmcs'.

Opportunistically make evmcs_sanitize_exec_ctrls '__init' and drop unneeded
extra newline from it.

Add a regression test for commit 671ddc700f ("KVM: nVMX: Don't leak
L1 MMIO regions to L2").

First, check to see that an L2 guest can be launched with a valid
APIC-access address that is backed by a page of L1 physical memory.

Next, set the APIC-access address to a (valid) L1 physical address
that is not backed by memory. KVM can't handle this situation, so
resuming L2 should result in a KVM exit for internal error
(emulation).

Gustavo A. R. Silva 290562075d net/mlx5: Replace zero-length array with flexible-array member
There is a regular need in the kernel to provide a way to declare having a
dynamically sized set of trailing elements in a structure. Kernel code should
always use “flexible array members”[1] for these cases. The older style of
one-element or zero-length arrays should no longer be used[2].

There is a regular need in the kernel to provide a way to declare having a
dynamically sized set of trailing elements in a structure.  Kernel code
should always use “flexible array members”[1] for these cases.  The
older style of one-element or zero-length arrays should no longer be
used[2].

Refactor the code according to the use of a flexible-array member in
struct gve_stats_report, instead of a zero-length array, and use the
struct_size() helper to calculate the size for the resource allocation.

This is a fairly large set of bug fixes on top of -rc1,

 	espressobin board

 	one bugfix for camera interface power-down
 
 NXP i.MX:
 	Re-enable the GPIO driver on all defconfigs
 
 ST STM32MP1:
 	Fix random crashes from incorrect voltage settings
 
 Synaptics Berlin:
 	Enable the correct hardware timer driver
 
 Texas Instruments K2G:
 	fix a boot regression in the power domain code
 
 TEE drivers:

 MAINTAINERS file:

 	Masahiro Yamada is stepping down as Uniphier maintainer
 
 I did not include a series of patches that work around a

 that resulted in an inadvertent DT binding change. This is

Takashi Iwai d383b3146d KVM: x86: Fix NULL dereference at kvm_msr_ignored_check()
The newly introduced kvm_msr_ignored_check() tries to print error or
debug messages via vcpu_*() macros, but those may cause Oops when NULL
vcpu is passed for KVM_GET_MSRS ioctl.

Fix it by replacing the print calls with kvm_*() macros.

(Note that this will leave vcpu argument completely unused in the
 function, but I didn't touch it to make the fix as small as
 possible.  A clean up may be applied later.)

Chris reported that commit 24d5a3bffef1 ("lockdep: Fix
usage_traceoverflow") breaks the nr_unused_locks validation code
triggered by /proc/lockdep_stats.

By fully splitting LOCK_USED and LOCK_USED_READ it becomes a bad
indicator for accounting nr_unused_locks; simplyfy by using any first
bit.

Peter Zijlstra d48e385003 locking/lockdep: Remove more raw_cpu_read() usage
I initially thought raw_cpu_read() was OK, since if it is !0 we have
IRQs disabled and can't get migrated, so if we get migrated both CPUs
must have 0 and it doesn't matter which 0 we read.

And while that is true; it isn't the whole store, on pretty much all
architectures (except x86) this can result in computing the address for
one CPU, getting migrated, the old CPU continuing execution with another
task (possibly setting recursion) and then the new CPU reading the value
of the old CPU, which is no longer 0.

Similer to:

Qais Yousef 22f553842b KVM: arm64: Handle Asymmetric AArch32 systems
On a system without uniform support for AArch32 at EL0, it is possible
for the guest to force run AArch32 at EL0 and potentially cause an
illegal exception if running on a core without AArch32. Add an extra
check so that if we catch the guest doing that, then we prevent it from
running again by resetting vcpu->arch.target and return
ARM_EXCEPTION_IL.

We try to catch this misbehaviour as early as possible and not rely on
an illegal exception occuring to signal the problem. Attempting to run a
32bit app in the guest will produce an error from QEMU if the guest
exits while running in AArch32 EL0.

Tested on Juno by instrumenting the host to fake asym aarch32 and
instrumenting KVM to make the asymmetry visible to the guest.

Ming Lei 65ff5cd045 blk-mq: mark flush request as IDLE in flush_end_io()
Mark flush request as IDLE in its .end_io(), aligning it with how normal
requests behave. The flush request stays in in-flight tags if we're not
using an IO scheduler, so we need to change its state into IDLE.
Otherwise, we will hang in blk_mq_tagset_wait_completed_request() during
error recovery because flush the request state is kept as COMPLETED.
