Instrumenting some files with KMSAN will result in kernel being unable to link, boot or crashing at runtime for various reasons (e.g. infinite recursion caused by instrumentation hooks calling instrumented code again). Disable KMSAN in the following places: - arch/x86/boot and arch/x86/realmode/rm, as KMSAN doesn't work for i386; - arch/x86/entry/vdso, which isn't linked with KMSAN runtime; - three files in arch/x86/kernel - boot problems; - arch/x86/mm/cpu_entry_area.c - recursion; - EFI stub - build failures; - kcov, stackdepot, lockdep - recursion. Signed-off-by: Alexander Potapenko <glider@google.com> --- v4: - fix lockdep support by not instrumenting lockdep.c - unified comments with KCSAN v6: - rebase after KCSAN merge Link: https://linux-review.googlesource.com/id/Id5e5c4a9f9d53c24a35ebb633b814c414628d81b
