Log message:
amd64: cpu_info: rearrange members, keep ci_mds_tmp 32-byte aligned
ci_mds_tmp needs to be 32-byte aligned, otherwise we trip a CTASSERT
in amd64/cpu.c and break kernel compilation. However, ci_mds_tmp's
32-byte alignment is at risk: the size of schedstate_percpu is about
to change.
Move ci_curproc and ci_schedstate up just after ci_mds_buf. This puts
ci_mds_tmp at page offset 64 with no structs ahead of it in cpu_info.
With this arrangement it should remain 32-byte aligned without much
effort.
With input from guenther@.
