[PATCH 04/18] KVM: X86: Introduce a tdp_set_cr3 function
This patch introduces a special set_tdp_cr3 function pointer in kvm_x86_ops which is only used for tpd enabled mmu contexts. This allows to remove some hacks from svm code.

[PATCH 18/18] KVM: X86: Add KVM_CAP_SVM_CPUID_FIXED
This capability shows userspace that is can trust the values of cpuid[0x8000000A] that it gets from the kernel. Old behavior was to just return the host cpuid values which is broken because all additional svm-features need support in the svm emulation code.

[PATCH 03/18] KVM: MMU: Make set_cr3 a function pointer in kvm_mmu
This is necessary to implement Nested Nested Paging. As a side effect this allows some cleanups in the SVM nested paging code.

[BUG #15248] Please apply the suggested fix
Hi, My notebook has an I855GME video card, this video card is one of the affected by the bug #15248 which produces a hard freeze shorly after the load of the i915 kernel module. A git bisect showed that the affecting patch producing the hard freeze was: commit b42d4c5c6a872815d711e5d51a600f5122c38eee Author... 3 Mar 2010 14:09
