Subject: x86/cpuid: add missing PCLMULQDQ dependency
X-Git-Url: http://xenbits.xensource.com/gitweb?a=commitdiff_plain;h=eeb31ee522c7bb8541eb4c037be2c42bfcf0a3c3;p=people%2Fpauldu%2Fxen.git

x86/cpuid: add missing PCLMULQDQ dependency

Since we can't seem to be able to settle our discussion for the wider
adjustment previously posted, let's at least add the missing dependency
for 4.12. I'm not convinced though that attaching it to SSE is correct.
