Since set_pte() is now the only caller of set_pte_common(), merge the two functions. Signed-off-by: NAvi Kivity <avi@qumranet.com>

If the guest requests just a tlb flush, don't take the vm lock and drop the mmu context pointlessly. Signed-off-by: NAvi Kivity <avi@qumranet.com>

If all we're doing is increasing permissions on a pte (typical for demand paging), then there's not need to flush remote tlbs. Worst case they'll get a spurious page fault. Signed-off-by: NAvi Kivity <avi@qumranet.com>

I spent an hour worrying why I see so many guest page faults on FC6 i386. Turns out bypass wasn't implemented for nonpae. Implement it so it doesn't happen again. Signed-off-by: NAvi Kivity <avi@qumranet.com>

Split kvm_arch_vcpu_create() into kvm_arch_vcpu_create() and kvm_arch_vcpu_setup(), enabling preemption notification between the two. This mean that we can now do vcpu_load() within kvm_arch_vcpu_setup(). Signed-off-by: NAvi Kivity <avi@qumranet.com>

Instead of incrementally changing the mmu cache size for every memory slot operation, recalculate it from scratch. This is simpler and safer. Signed-off-by: NZhang Xiantao <xiantao.zhang@intel.com> Signed-off-by: NAvi Kivity <avi@qumranet.com>

Instead of fetching one byte at a time, prefetch 15 bytes (or until the next page boundary) to avoid guest page table walks. Signed-off-by: NAvi Kivity <avi@qumranet.com>

Theoretically used to acccess memory known to be ordinary RAM, it was never implemented. It is questionable whether it is possible to implement it correctly. Signed-off-by: NAvi Kivity <avi@qumranet.com>

Improve dirty bit setting for pages that kvm release, until now every page that we released we marked dirty, from now only pages that have potential to get dirty we mark dirty. Signed-off-by: NIzik Eidus <izike@qumranet.com> Signed-off-by: NAvi Kivity <avi@qumranet.com>

When we map a page, we check whether some other vcpu mapped it for us and if so, bail out. But we should decrease the refcount on the page as we do so. Signed-off-by: NIzik Eidus <izike@qumranet.com> Signed-off-by: NAvi Kivity <avi@qumranet.com>

Ensure that segment.base == segment.selector << 4 when entering the real mode on Intel so that the CPU will not bark at us.
