x86, avx: don't use avx instructions with "noxsave" boot param
Clear AVX, AVX2 features along with clearing XSAVE feature bits, as part of the parsing "noxsave" parameter. Fixes the kernel boot panic with "noxsave" boot parameter. We could have checked cpu_has_osxsave along with cpu_has_avx etc, but Peter mentioned clearing the feature bits will be better for uses like static_cpu_has() etc. Signed-off-by: Suresh Siddha <suresh.b.siddha@intel.com> Link: http://lkml.kernel.org/r/1343755754.2041.2.camel@sbsiddha-desk.sc.intel.com Cc: <stable@vger.kernel.org> # v3.5 Signed-off-by: H.
