Alexander Potapenko 93324e6842 x86: kmsan: disable instrumentation of unsupported code 
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).

Completely omit KMSAN instrumentation 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.
