* KVM: Fix gfn_to_page() acquiring mmap_sem twiceAnthony Liguori2008-01-301-4/+18
| | | | | | | | | | | | KVM's nopage handler calls gfn_to_page() which acquires the mmap_sem when calling out to get_user_pages(). nopage handlers are already invoked with the mmap_sem held though. Introduce a __gfn_to_page() for use by the nopage handler which requires the lock to already be held. This was noticed by tglx.

* KVM: VMX: Enable memory mapped TPR shadow (FlexPriority)Sheng Yang2008-01-301-17/+39
| | | | | | | | | | This patch based on CR8/TPR patch, and enable the TPR shadow (FlexPriority) for 32bit Windows. Since TPR is accessed very frequently by 32bit Windows, especially SMP guest, with FlexPriority enabled, we saw significant performance gain.

* KVM: Portability: Move control register helper functions to x86.cCarsten Otte2008-01-301-219/+0Star
| | | | | | | | | | | | | | | | | | This patch moves the definitions of CR0_RESERVED_BITS, CR4_RESERVED_BITS, and CR8_RESERVED_BITS along with the following functions from kvm_main.c to x86.c: set_cr0(), set_cr3(), set_cr4(), set_cr8(), get_cr8(), lmsw(), load_pdptrs() The static function wrapper inject_gp is duplicated in kvm_main.c and x86.c for now, the version in kvm_main.c should disappear once the last user of it is gone too. The function load_pdptrs is no longer static, and now defined in x86.h for the time being, until the last user of it is gone from kvm_main.c.
