Dear stable kernel maintainers,
Please consider applying the following backports of commit
e0d5896bd356 ("arm64: lse: fix LSE atomics with LLVM's integrated
assembler") which first landed in v5.6-rc1 and was already picked up
into linux-5.4.y as f68668292496 in v5.4.22 (adjusted for a conflict
due to commit addfc38672c7 ("arm64: atomics: avoid out-of-line ll/sc
atomics") which landed in v5.4-rc1).
Also contains a fix for that first patch which cherry-picks cleanly,
commit dd1f6308b28e ("arm64: lse: Fix LSE atomics with LLVM").
The attached patches allow for Android and CrOS to build with
LLVM_IAS=1 for arm64 for v4.19.y (modulo one small patch that I will
send tomorrow).

Thanks,
~Nick Desaulniers
