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 arch/x86/include/asm/fpu-internal.h | 118 +++++++++++++++++++--------------- arch/x86/include/asm/i387.h | 1 + arch/x86/include/asm/xor_32.h | 56 +++-------------- arch/x86/include/asm/xor_64.h | 61 +++--------------- arch/x86/include/asm/xor_avx.h | 54 ++++------------ arch/x86/include/asm/xsave.h | 1 + arch/x86/kernel/i387.c | 20 +++++- arch/x86/kernel/process.c | 12 +++- arch/x86/kernel/process_32.c | 4 - arch/x86/kernel/process_64.c | 4 - arch/x86/kernel/traps.c | 5 +- arch/x86/kernel/xsave.c | 58 +++++++++++++---- arch/x86/kvm/x86.c | 3 +- drivers/lguest/x86/core.c | 10 ++- 14 files changed, 180 insertions(+), 227 deletions(-) -- 1.7.6.5 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
