1. I'm seeing the following build failures on s390 due to,
## Build errors: arch/s390/include/asm/fpu-insn.h: In function 'fpu_vst': arch/s390/include/asm/fpu-insn.h:381:36: error: 'size' undeclared (first use in this function); did you mean 'ksize'? 381 | kmsan_unpoison_memory(vxr, size); | ^~~~ | ksize
The commit point to, s390/fpu: Fix false-positive kmsan report in fpu_vstl() [ Upstream commit 14e4e4175b64dd9216b522f6ece8af6997d063b2 ]
2. The clang-21 allyesconfig builds failed on on arm, arm64, riscv and x86_64 as it was reported on the 6.18.2-rc1 and 6.17.13-rc2.
