Commit 225ae5fd9a
"MIPS: Malta: Fix interupt number of CBUS UART"
fixed the IRQ number for the ttyS2 CBUS UART. However, this now
conflicts with the GIC IPI1 interrupt in CMP platforms. The Malta
interrupt code arbitrarily binds IPIs to INT2 and INT3 and since
ttyS2 uses the INT2 IRQ line, closing the device disables the
INT2 interrupt and this effectively disables the IPI1 interrupt
as well. This patch is mainly a workaround until the Malta code
is fixed properly.

CPUs implementing MIPS32 R2 may include a 64-bit FPU, just as MIPS64 CPUs
do. In order to preserve backwards compatibility a 64-bit FPU will act
like a 32-bit FPU (by accessing doubles from the least significant 32
bits of an even-odd pair of FP registers) when the Status.FR bit is
zero, again just like a mips64 CPU. The standard O32 ABI is defined
expecting a 32-bit FPU, however recent toolchains support use of a
64-bit FPU from an O32 MIPS32 executable. When an ELF executable is
built to use a 64-bit FPU a new flag (EF_MIPS_FP64) is set in the ELF
header.
With this patch the kernel will check the EF_MIPS_FP64 flag when
executing an O32 binary, and set Status.FR accordingly. The addition
of O32 64-bit FP support lessens the opportunity for optimisation in
the FPU emulator, so a CONFIG_MIPS_O32_FP64_SUPPORT Kconfig option is
introduced to allow this support to be disabled for those that don't
require it.
Inspired by an earlier patch by Leonid Yegoshin, but implemented more
cleanly & correctly.

Investigating, I found that the inode->i_security was NULL, and the
dereference of it caused the oops.
in selinux_inode_permission():
isec = inode->i_security;
rc = avc_has_perm_noaudit(sid, isec->sid, isec->sclass, perms, 0, &avd);
Note, the crash came from stressing the deletion and reading of debugfs
files. I was not able to recreate this via normal files. But I'm not
sure they are safe. It may just be that the race window is much harder
to hit.
What seems to have happened (and what I have traced), is the file is
being opened at the same time the file or directory is being deleted.
As the dentry and inode locks are not held during the path walk, nor is
the inodes ref counts being incremented, there is nothing saving these
structures from being discarded except for an rcu_read_lock().
The rcu_read_lock() protects against freeing of the inode, but it does
not protect freeing of the inode_security_struct. Now if the freeing of
the i_security happens with a call_rcu(), and the i_security field of
the inode is not changed (it gets freed as the inode gets freed) then
there will be no issue here. (Linus Torvalds suggested not setting the
field to NULL such that we do not need to check if it is NULL in the
permission check).
Note, this is a hack, but it fixes the problem at hand. A real fix is
to restructure the destroy_inode() to call all the destructor handlers
from the RCU callback. But that is a major job to do, and requires a
lot of work. For now, we just band-aid this bug with this fix (it
works), and work on a more maintainable solution in the future.

Pull xfs bugfixes from Ben Myers:
"Here we have a bugfix for an off-by-one in the remote attribute
verifier that results in a forced shutdown which you can hit with v5
superblock by creating a 64k xattr, and a fix for a missing
destroy_work_on_stack() in the allocation worker.
It's a bit late, but they are both fairly straightforward"

leds: lp5521/5523: Remove duplicate mutex
- Recent commits modifying the lists of C-states in the intel_idle
driver introduced bugs leading to crashes on some systems. Two
fixes from Jiang Liu.
- The ACPI AC driver should receive all types of notifications, but
recent change made it ignore some of them. Fix from Alexander Mezin.
- intel_pstate's validity checks for MSRs it depends on are not
sufficient to catch the lack of support in nested KVM setups, so
they are extended to cover that case. From Dirk Brandewie.
- NEC LZ750/LS has a botched up _BIX method in its ACPI tables, so our
ACPI battery driver needs a quirk for it. From Lan Tianyu.
- The tpm_ppi driver sometimes leaks memory allocated by acpi_get_name().
Fix from Jiang Liu.

intel_idle: close avn_cstates array with correct marker
Revert "intel_idle: mark states tables with __initdata tag"
ACPI / Battery: Add a _BIX quirk for NEC LZ750/LS
intel_pstate: Add X86_FEATURE_APERFMPERF to cpu match parameters.
ACPI / TPM: fix memory leak when walking ACPI namespace
ACPI / AC: change notification handler type to ACPI_ALL_NOTIFY
It only contains one fix for the rtsx_pcr driver. Without it we see a
kernel panic on some machines, when resuming from suspend to RAM.

It only contains one fix for the rtsx_pcr driver. Without it we see a

mfd: rtsx_pcr: Disable interrupts before cancelling delayed works
It can be a problem when a pattern is loaded via the firmware interface.
LP55xx common driver has already locked the mutex in 'lp55xx_firmware_loaded()'.
So it should be deleted.
On the other hand, locks are required in store_engine_load()
on updating program memory.
