Subject: [PATCH 0/2] KVM: SVM: convert get_user_pages() --> pin_user_pages(), bug fixes

Hi,

This is just for the SEV (Secure Encrypted Virtualization) part of KVM.
It converts the get_user_pages_fast() call, after fixing a couple of
small bugs in the vicinity.

Note that I have only compile-tested these two patches, so any run-time
testing coverage would be greatly appreciated.
