    Subject[PATCH 0/6] x86, fpu: cleanups, introduce non-lazy FPU restore for xsave
    Date
    These patches are against tip/x86/fpu. Few cleanups and more improtantly
    this series introduces the non-lazy FPU restore mechanism for processors
    supporting xsave feature. More details in the individual patch changelogs.

    Thanks.

    Suresh Siddha (6):
    x86, fpu: drop_fpu() before restoring new state from sigframe
    x86, fpu: remove unnecessary user_fpu_end() in save_xstate_sig()
    x86, kvm: use kernel_fpu_begin/end() in kvm_load/put_guest_fpu()
    x86, fpu: always use kernel_fpu_begin/end() for in-kernel FPU usage
    lguest, x86: handle guest TS bit for lazy/non-lazy fpu host models
    x86, fpu: use non-lazy fpu restore for processors supporting xsave
