From 60e019eb37a8d989031ad47ae9810453536f3127 Mon Sep 17 00:00:00 2001 From: "H. Peter Anvin" Date: Mon, 29 Apr 2013 16:04:20 +0200 Subject: x86: Get rid of ->hard_math and all the FPU asm fu Reimplement FPU detection code in C and drop old, not-so-recommended detection method in asm. Move all the relevant stuff into i387.c where it conceptually belongs. Finally drop cpuinfo_x86.hard_math. [ hpa: huge thanks to Borislav for taking my original concept patch and productizing it ] [ Boris, note to self: do not use static_cpu_has before alternatives! ] Signed-off-by: H.
