Sebastian Andrzej Siewior c2ff9e9a3d x86/fpu: Merge the two code paths in __fpu__restore_sig() ... The ia32_fxstate case (32bit with fxsr) and the other (64bit frames or 32bit frames without fxsr) restore both from kernel memory and sanitize the content. The !ia32_fxstate version restores missing xstates from "init state" while the ia32_fxstate doesn't and skips it. Merge the two code paths and keep the !ia32_fxstate one. Copy only the user_i387_ia32_struct data structure in the ia32_fxstate.
