From d1e509660c690597edb7e15efd22a5e78b8e2fd5 Mon Sep 17 00:00:00 2001 From: Ingo Molnar Date: Tue, 28 Apr 2015 10:11:24 +0200 Subject: [PATCH] x86/fpu, crypto x86/sha1_ssse3: Simplify the sha1_ssse3_mod_init() xfeature checks Use the new 'cpu_has_xfeatures()' function to query AVX CPU support. This has the following advantages to the driver: - Decouples the driver from FPU internals: it's now only using . - Removes detection complexity from the driver, no more raw XGETBV instruction - Shrinks the code a bit. - Standardizes feature name error message printouts across drivers There are also advantages to the x86 FPU code: once all drivers are decoupled from internals we can move them out of common headers and we'll also be able to remove xcr.h.
