Currently we can hit following assert when running numa bench:
$ perf bench numa mem -p 3 -t 1 -P 512 -s 100 -zZ0cm --thp 1
perf: bench/numa.c:1577: __bench_numa: Assertion `!(!(((wait_stat) & 0x7f) == 0))' failed.
The assertion is correct, because we hit the SIGFPE in following line:
Thread 2.2 "thread 0/0" received signal SIGFPE, Arithmetic exception.
[Switching to Thread 0x7fffd28c6700 (LWP 11750)]

1257 td->speed_gbs = bytes_done / (td->runtime_ns / NSEC_PER_SEC) / 1e9;
We don't check if the runtime is actually bigger than 1 second,
and thus this might end up with zero division within FPU.
Adding the check to prevent this.

F/ix this by adding the platform architecture into the perf data header

The line numers for if-entries in the menu tree are off by one or more
lines which is confusing when debugging for correctness of unrelated changes.
According to the git log, commit a02f0570ae201c49 (kconfig: improve
error handling in the parser) was the last one that changed that part
of the parser and replaced
"if_entry: T_IF expr T_EOL"
by
"if_entry: T_IF expr nl"
but the commit message does not state why this has been done.
When reverting that part of the commit, only the line numers are
corrected (checked with cdebug = DEBUG_PARSE in zconf.y), otherwise
the menu tree remains unchanged (checked with zconfdump() enabled in
conf.c).
An example for the corrected line numbers:

It happens only when INT_MAX is passed there, as we're incrementing it
unconditionally. So the fix is trivial, check the value with
INT_MAX. Although the bug itself is fairly harmless, it's better to
fix it so that fuzzers won't hit this again later.

Smack: Mark inode instant in smack_task_to_inode
/proc clean-up in commit 1bbc55131e59bd099fdc568d3aa0b42634dbd188
resulted in smack_task_to_inode() being called before smack_d_instantiate.
This resulted in the smk_inode value being ignored, even while present
for files in /proc/self. Marking the inode as instant here fixes that.

After recieving MLD querys, we update idev->mc_maxdelay with max_delay
from query header. This make the later unsolicited reports have the same
interval with mc_maxdelay, which means we may send unsolicited reports with
long interval time instead of default configured interval time.
Also as we will not call ipv6_mc_reset() after device up. This issue will
be there even after leave the group and join other groups.

While debugging where things were going wrong with mapping
enabling/disabling interrupts with the lockdep state and actual real
enabling and disabling interrupts, I had to silent the IRQ
disabling/enabling in debug_check_no_locks_freed() because it was
always showing up as it was called before the splat was.
Use raw_local_irq_save/restore() for not only debug_check_no_locks_freed()
but for all internal lockdep functions, as they hide useful information
about where interrupts were used incorrectly last.

[ Upstream commit ba56bc3a0786992755e6804fbcbdc60ef6cfc24c ]
When booting a 64 KB pages kernel on a ACPI GICv3 system that
implements support for v2 emulation, the following warning is
produced
GICV size 0x2000 not a multiple of page size 0x10000
and support for v2 emulation is disabled, preventing GICv2 VMs
from being able to run on such hosts.
The reason is that vgic_v3_probe() performs a sanity check on the
size of the window (it should be a multiple of the page size),
while the ACPI MADT parsing code hardcodes the size of the window
to 8 KB. This makes sense, considering that ACPI does not bother
to describe the size in the first place, under the assumption that
platforms implementing ACPI will follow the architecture and not
put anything else in the same 64 KB window.
So let's just drop the sanity check altogether, and assume that
the window is at least 64 KB in size.

The Stratix10 platform has an additional reset line, OCP(Open Core Protocol),

Thus we need to update the Kconfig to include ARCH_STRATIX10 in order to build

Also, remove the redundant check for the reset controller pointer. The
reset driver already checks for the pointer and returns 0 if the pointer
is NULL.
