[PATCH 14/39] KVM: PPC: Pass program interrupt flags to the guest
From: Alexander Graf <agraf(a)suse.de> When we need to reinject a program interrupt into the guest, we also need to reinject the corresponding flags into the guest.

[PATCH 17/39] KVM: VMX: trace clts and lmsw instructions as cr accesses

[PATCH 24/39] KVM: SVM: Initialize fpu_active in init_vmcb()
init_vmcb() sets up the intercepts as if the fpu is active, so initialize it there. This avoids an INIT from setting up intercepts inconsistent with fpu_active.

[PATCH 15/39] KVM: PPC: Pass through program interrupts
From: Alexander Graf <agraf(a)suse.de> When we get a program interrupt in guest kernel mode, we try to emulate the instruction. If that doesn't fail, we report to the user and try again - at the exact same instruction pointer. So if the guest kernel really does trigger an invalid instruction, we loop forever. ... 13 Feb 2010 03:52

[PATCH 21/39] KVM: VMX: Give the guest ownership of cr0.ts when the fpu is active
If the guest fpu is loaded, there is nothing interesing about cr0.ts; let the guest play with it as it will. This makes context switches between fpu intensive guest processes faster, as we won't trap the clts and cr0 write instructions.
