Description

In the Linux kernel, the following vulnerability has been resolved: KVM: SEV: Fix page dirtying in sev_gmem_post_populate() set_page_dirty() requires that the caller holds some kind of lock to ensure that the page's mapping does not concurrently go away. That is not the case for a random page we got from get_user_pages_fast(), so use set_page_dirty_lock(). [sean: tag for stable]
