      perf s390: Move syscall.tbl check into check-headers.sh · 22ffc3f5
      Tiezhu Yang authored 
      It is better to check syscall.tbl for s390 in check-headers.sh, it is
similar with commit c9b51a01 ("perf tools: Move syscall_64.tbl check
into check-headers.sh").

The new MSR has a pattern that wasn't matched to avoid a clash with
IA32_UCODE_REV, change the regex to prefer the more relevant AMD_
