Linus,

Miscellaneous x86 fixes:

- Improve Qemu MCE-injection behavior by only using
AMD SMCA MSRs if the feature bit is set.

- Fix the relative path of gettimeofday.c inclusion
in vclock_gettime.c

- Fix a boot crash on UV clusters when a socket is
marked as 'deconfigured' which are mapped to the
SOCK_EMPTY (0xffff [short -1]) node ID by the UV firmware,
while Linux APIs expect NUMA_NO_NODE (0xffffffff [int -1]).

Thanks,

Ingo
