x86: Fix ASM_X86__ header guards Change header guards named "ASM_X86__" to "_ASM_X86_" since: a. the double underscore is ugly and pointless. b. no leading underscore violates namespace constraints.

x86, xsave: save/restore the extended state context in sigframe On cpu's supporting xsave/xrstor, fpstate pointer in the sigcontext, will include the extended state information along with fpstate information. Presence of extended state information is indicated by the presence of FP_XSTATE_MAGIC1 at fpstate.sw_reserved.magic1 and FP_XSTATE_MAGIC2 at fpstate + (fpstate.sw_reserved.extended_size - FP_XSTATE_MAGIC2_SIZE). Extended feature bit mask that is saved in the memory layout is represented by the fpstate.sw_reserved.xstate_bv For RT signal frames, UC_FP_XSTATE in the uc_flags also indicate the presence of extended state information in the sigcontext's fpstate pointer.

x86: remove all now-duplicate header files All files that have been made identical to the asm-generic version in the previous patches can now be removed, guaranteeing that this does not introduce semantic changes.
