Subject: crypto x86/camellia_aesni_avx: Fix CPU feature checks
|
||||
Bug-Debian: https://bugs.debian.org/800934
|
||||
Forwarded: http://mid.gmane.org/1444131093.2956.122.camel@decadent.org.uk
|
||||
|
||||
We need to explicitly check the AVX and AES CPU features, as we can't
|
||||
infer them from the related XSAVE feature flags. For example, the
|
||||
Core i3 2310M passes the XSAVE feature test but does not implement
|
||||
AES-NI.
