The value of FP registers in the core dump file comes from the
thread.fstate. However, kernel saves the FP registers to the thread.fstate
only before scheduling out the process. If no process switch happens
during the exception handling process, kernel will not have a chance to
save the latest value of FP registers to thread.fstate. It will cause the
value of FP registers in the core dump file may be incorrect. To solve this
problem, this patch force lets kernel save the FP register into the
thread.fstate if the target task_struct equals the current.

We found a hang, the steps to reproduce are as follows:

2. dd if=/dev/sda of=/mnt/t.log bs=1M count=10
3. echo none > /sys/block/sda/queue/scheduler
4. echo "running" >/sys/block/sda/device/state
Step 3 and 4 should complete after step 4, but they hang.

In early erratas this issue only covered port 0 when changing from
[x]MII (rev A 3.6). In subsequent errata versions this errata changed to
cover the additional "Hardware reset in CPU managed mode" condition, and
removed the note specifying that it only applied to port 0.
In designs where the device is configured with CPU managed mode
(CPU_MGD), on reset all SERDES ports (p0, p9, p10) have a stuck power
down bit and require this initial power up procedure. As such apply this
errata to all three SERDES ports of the mv88e6393x.

After investigation the problem turned out to be that ucount_max for
the rlimits in init_user_ns was being set to the initial rlimit value.
The practical problem is that ucount_max provides a limit that
applications inside the user namespace can not exceed. Which means in
practice that rlimits that have been converted to use the ucount
infrastructure were not able to exceend their initial rlimits.
Solve this by setting the relevant values of ucount_max to
RLIM_INIFINITY. A limit in init_user_ns is pointless so the code
should allow the values to grow as large as possible without riscking
an underflow or an overflow.
As the ltp test case was a bit of a pain I have reproduced the rlimit failure
and tested the fix with the following little C program:

Commit 457f44363a ("bpf: Implement BPF ring buffer and verifier support
for it") extended check_map_func_compatibility() by enforcing map -> helper
function match, but not helper -> map type match.
Due to this all of the bpf_ringbuf_*() helper functions could be used with
a wrong map type such as array or hash map, leading to invalid access due
to type confusion.
Also, both BPF_FUNC_ringbuf_{submit,discard} have ARG_PTR_TO_ALLOC_MEM as
argument and not a BPF map. Therefore, their check_map_func_compatibility()
presence is incorrect since it's only for map type checking.

This reverts commit 819fbd3d8e.
It turns out that some user-space applications use these uapi header
files, so even though the only user of the interface is an old driver
that was moved to staging, moving the header files causes unnecessary
pain.
Generally, we really don't want user space to use kernel headers
directly (exactly because it causes pain when we re-organize), and
instead copy them as needed. But these things happen, and the headers
were in the uapi directory, so I guess it's not entirely unreasonable.

For this adapter we call ax88178_bind() and ax88772_unbind(), which is

resulting in segfaults. Prior to this patch IS_ERR was also checked on
required_opp_tables[i] before reading ->is_genpd inside
_opp_table_alloc_required_tables, which is at the same time the
predicate to add this table to the lazy list. This segfault is solved
by reordering the checks to bail on lazy pending tables before reading
->is_genpd.

The recent commit
064855a690 ("x86/resctrl: Fix default monitoring groups reporting")
caused a RHEL build failure with an uninitialized variable warning
treated as an error because it removed the default case snippet.
The RHEL Makefile uses '-Werror=maybe-uninitialized' to force possibly
uninitialized variable warnings to be treated as errors. This is also
reported by smatch via the 0day robot.
The error from the RHEL build is:
arch/x86/kernel/cpu/resctrl/monitor.c: In function ‘__mon_event_count’:
arch/x86/kernel/cpu/resctrl/monitor.c:261:12: error: ‘m’ may be used
uninitialized in this function [-Werror=maybe-uninitialized]
m->chunks += chunks;
^~
The upstream Makefile does not build using '-Werror=maybe-uninitialized'.
So, the problem is not seen there. Fix the problem by putting back the
default case snippet.
[ bp: note that there's nothing wrong with the code and other compilers
do not trigger this warning - this is being done just so the RHEL compiler
is happy. ]

79419e13e8 ("x86/boot/compressed/64: Setup IDT in startup_32 boot path")
introduced an IDT into the 32-bit boot path of the decompressor stub.
But the IDT is set up before ExitBootServices() is called, and some UEFI
firmwares rely on their own IDT.
Save the firmware IDT on boot and restore it before calling into EFI
functions to fix boot failures introduced by above commit.

"Regularly scheduled fixes. The ttm one solves a problem of GPU drivers
failing to load if debugfs is off in Kconfig, otherwise the i915 and
mediatek, and amdgpu fixes all fairly normal.
Nouveau has a couple of display fixes, but it has a fix for a
longstanding race condition in it's memory manager code, and the fix
mostly removes some code that wasn't working properly and has no
userspace users. This fix makes the diffstat kinda larger but in a
good (negative line-count) way.
