To pick up the changes in:
ed5194c2732c ("x86/speculation/mds: Add basic bug infrastructure for MDS")
e261f209c366 ("x86/speculation/mds: Add BUG_MSBDS_ONLY")
That don't affect anything in tools/.
This silences this perf build warning:
Warning: Kernel ABI header at 'tools/arch/x86/include/asm/cpufeatures.h'
