commit 034f4a7877c32a8efd6beee4d71ed14e424499a9 upstream.
gcc-13 may generate calls for __bswap{si,di}2. This breaks the kernel
build when optimization for size is selected. Add __bswap{si,di}2
helpers to fix that.

xtensa: add __umulsidi3 helper2023-01-07T10:11:46+00:00Max Filippovjcmvbkbc@gmail.com2022-12-05T21:19:21+00:00urn:sha1:aa3e7a48e921aeb6a0e01c3a474db50de6c9bcac
commit 8939c58d68f97ce530f02d46c9f2b56c3ec88399 upstream.
xtensa gcc-13 has changed multiplication handling and may now use
__umulsidi3 helper where it used to use __muldi3. As a result building
the kernel with the new gcc may fail with the following error:
linux/init/main.c:1287: undefined reference to `__umulsidi3'
Fix the build by providing __umulsidi3 implementation for xtensa.

xtensa: enable KCSAN2022-05-02T02:51:22+00:00Max Filippovjcmvbkbc@gmail.com2019-10-05T06:33:31+00:00urn:sha1:725aea873261e8d986e527838fde2a721f0962d8
Prefix arch-specific barrier macros with '__' to make use of instrumented
generic macros.
Prefix arch-specific bitops with 'arch_' to make use of instrumented
generic functions.
Provide stubs for 64-bit atomics when building with KCSAN.
Disable KCSAN instrumentation in arch/xtensa/boot.

xtensa: add helpers for division, remainder and shifts2022-03-09T22:02:40+00:00Max Filippovjcmvbkbc@gmail.com2021-10-18T11:29:27+00:00urn:sha1:dbf4ed894c0fd85d421f7b3b9758ce95398d2925
Don't rely on libgcc presence, build own versions of the helpers with
correct ABI.
