The FPU_STAT_CREATE_EX() macro used 114 times in debugfs_fpuemu()
declares a 32 byte char array to hold the name of a debugfs file. Since
each use of the macro declares a new char array out of the scope of all
the other uses, we end up with an unnecessarily large stack frame of
3648 bytes (ie. 114*32) plus the size of 2 pointers
(fpuemu_debugfs_base_dir & fpuemu_debugfs_inst_dir). This is enough to
trigger the frame size warnings from GCC in common configurations.
Avoid the unnecessary stack bloat by using a single name char array
which each usage of FPU_STAT_CREATE_EX() will reinitialize via the
strcpy() in adjust_instruction_counter_name().

During rename exchange we might have successfully log the new name in the
source root's log tree, in which case we leave our log context (allocated
on stack) in the root's list of log contextes. However we might fail to
log the new name in the destination root, in which case we fallback to
a transaction commit later and never sync the log of the source root,
which causes the source root log context to remain in the list of log
contextes. This later causes invalid memory accesses because the context
was allocated on stack and after rename exchange finishes the stack gets
reused and overwritten for other purposes.
The kernel's linked list corruption detector (CONFIG_DEBUG_LIST=y) can
detect this and report something like the following:

There are mixed LOONGSON3/LOONGSON64 usages in recently changes, let's
establish some rules:
1, In Kconfig symbols, we only use CPU_LOONGSON64, MACH_LOONGSON64 and
SYS_HAS_CPU_LOONGSON64, all other derived symbols use "LOONGSON3" since
they all not widely-used symbols and sometimes not suitable for all
64-bit Loongson processors. E.g., we use symbols LOONGSON3_ENHANCEMENT,
CPU_LOONGSON3_WORKAROUNDS, etc.
2, Hide GSx64/GSx64E in Kconfig title since it is not useful for
general users. However, in the full description we use a more detailed
manner. E.g., GS264/GS464/GS464E/GS464V.
All Kconfig titles and descriptions of Loongson processors and machines
have also been updated in this patch for consistency.

nvme devices report temperature information in the controller information
(for limits) and in the smart log. Currently, the only means to retrieve
this information is the nvme command line interface, which requires
super-user privileges.
At the same time, it would be desirable to be able to use NVMe temperature
information for thermal control.
This patch adds support to read NVMe temperatures from the kernel using the
hwmon API and adds temperature zones for NVMe drives. The thermal subsystem
can use this information to set thermal policies, and userspace can access
it using libsensors and/or the "sensors" command.
Example output from the "sensors" command:
nvme0-pci-0100
Adapter: PCI adapter
Composite: +39.0°C (high = +85.0°C, crit = +85.0°C)
Sensor 1: +39.0°C

On ia64 ioremap_nocache fails if attributes don't match. Not other

So get rid of the special semantics and define ioremap_nocache in
terms of ioremap as no portable driver could rely on the behavior
anyway.
However x86 implements ioremap_uc in a similar way as the ia64
version of ioremap_nocache, in that it ignores the firmware tables.

When a jump_whitelist bitmap is reused, it needs to be cleared.
Currently this is done with memset() and the size calculation assumes
bitmaps are made of 32-bit words, not longs. So on 64-bit
architectures, only the first half of the bitmap is cleared.
If some whitelist bits are carried over between successive batches
submitted on the same context, this will presumably allow embedding
the rogue instructions that we're trying to reject.
Use bitmap_zero() instead, which gets the calculation right.

This patch avoids that core component modules are being unloaded
while the related configfs interface has active items in its directories.
It is needed to prevent the situation where the core module cannot
be unloaded anymore, because the reference count 'used by' indicates that
the module is still being used and the usage count cannot be decreased by
calling rmdir, as the configfs directory has already been removed.

This patch moves the declarations of the configfs subsystems to
a superordinate container structure. This is done to get access
to private subsystem data.

The driver only binds by SDIO device-ids, all the ACPI device-id does
is causing the driver to load unnecessarily on devices where the DSDT
contains a bogus OBDA8723 device.

Add 024c:0525 to the list of SDIO device-ids, based on a patch found
in the Android X86 kernels. According to that patch this device id is
used on the Alcatel Plus 10 device.

Do not copy the extended supported rates in 'param->supp_rates' if the
array is already full with basic rates values. The array size check
helped to avoid possible illegal memory access [1] while copying to
'param->supp_rates' array.

Similar to commit 46c9a946d7 ("shmem: use monotonic time for i_generation")
we should not use the deprecated get_seconds() interface for i_generation.
prandom_u32() is the replacement used in other file systems.

For both PASID-based-Device-TLB Invalidate Descriptor and
Device-TLB Invalidate Descriptor, the Physical Function Source-ID
value is split according to this layout:
PFSID[3:0] is set at offset 12 and PFSID[15:4] is put at offset 52.
Fix the part laid out at offset 52.
