percpu_xxx funcs are duplicated with this_cpu_xxx funcs, so replace them for further code clean up. And in preempt safe scenario, __this_cpu_xxx funcs has a bit better performance since __this_cpu_xxx has no redundant preempt_disable() Signed-off-by:

This patch cleans and simplifies kvm_dev_ioctl_get_supported_cpuid by using a table instead of duplicating code as Avi suggested. This patch also fixes a bug where kvm_dev_ioctl_get_supported_cpuid would return -E2BIG when amount of entries passed was just right. Signed-off-by:

Intel latest cpu add 6 new features, refer http://software.intel.com/file/36945 The new feature cpuid listed as below: 1. FMA CPUID.EAX=01H:ECX.FMA[bit 12] 2. MOVBE CPUID.EAX=01H:ECX.MOVBE[bit 22] 3. BMI1 CPUID.EAX=07H,ECX=0H:EBX.BMI1[bit 3] 4. AVX2 CPUID.EAX=07H,ECX=0H:EBX.AVX2[bit 5] 5. BMI2 CPUID.EAX=07H,ECX=0H:EBX.BMI2[bit 8] 6. LZCNT CPUID.EAX=80000001H:ECX.LZCNT[bit 5] This patch expose these features to guest. Among them, FMA/MOVBE/LZCNT has already been defined, MOVBE/LZCNT has already been exposed. This patch defines BMI1/AVX2/BMI2, and exposes FMA/BMI1/AVX2/BMI2 to guest. Signed-off-by:

This fixes byte accesses to IOAPIC_REG_SELECT as mandated by at least the ICH10 and Intel Series 5 chipset specs. It also makes ioapic_mmio_write consistent with ioapic_mmio_read, which also allows byte and word accesses. Signed-off-by:
