b53bc74c6c Revert "ANDROID: cpu-hotplug: Always use real time scheduling when hotplugging a CPU"
This reverts commit c6e5f9d7cf.

This causes merge problems with 5.19-rc1 and should no longer be needed
anymore.

If it is needed, please work to get the needed changes upstream first,
these should not be sticking around in the Android tree for no good
reason.

3d41a21a35 ANDROID: irq-gic-v3: remove all out-of-tree changes
There have been a lot of out-of-tree changes to the irq-gic-v3.c driver
that never got merged upstream.  But other changes have been merged
upstream so resolving these merges has gotten way too complex.

So drop all out-of-tree changes for now to make merges easier.  If the
out-of-tree changes really are needed, they can be added back later
(after they are at least submitted upstream first.)

1c569481ec ANDROID: uapi: icmp: Bionic compat with __unused
Building CONFIG_UAPI_HEADER_TEST=y with a Bionic (Android's libc) based
sysroot produces the following warning:

In file included from <built-in>:1:
./usr/include/linux/icmp.h💯3: warning: declaration does not declare
anything [-Wmissing-declarations]
__be16  __unused;
^~~~~~

This is because Bionic defines __unused to expand to
__attribute__((__unused__)). Bionic pre-processes kernel headers and
redefines __unused to __linux_unused.

Do so here to avoid issues that only appear for Bionic based sysroot
UAPI header tests.

Linus Torvalds
cfe1cb014b A set of patches to prevent crashes in SGX enclaves under heavy memory
pressure:
 
 SGX uses normal RAM allocated from special shmem files as backing storage
 when it runs out of SGX memory (EPC).  The code was overly aggressive when
 freeing shmem pages and was inadvertently freeing perfectly good data.
 This resulted in failures in the SGX instructions used to swap data back
 into SGX memory.
 
 This turned out to be really hard to trigger in mainline.  It was
 originally encountered testing the out-of-tree "SGX2" patches, but later
 reproduced on mainline.
 
 Fix the data loss by being more careful about truncating pages out of
 the backing storage and more judiciously setting pages dirty.

3a755ebcc2 Intel Trust Domain Extensions
This is the Intel version of a confidential computing solution called
 Trust Domain Extensions (TDX). This series adds support to run the
 kernel as part of a TDX guest. It provides similar guest protections to
 AMD's SEV-SNP like guest memory and register state encryption, memory
 integrity protection and a lot more.
 
 Design-wise, it differs from AMD's solution considerably: it uses
 a software module which runs in a special CPU mode called (Secure
 Arbitration Mode) SEAM. As the name suggests, this module serves as sort
 of an arbiter which the confidential guest calls for services it needs
 during its lifetime.
 
 Just like AMD's SNP set, this series reworks and streamlines certain
 parts of x86 arch code so that this feature can be properly accomodated.
