corruption in 32-bit guest # - Add missing cache invalidation for CoW pages # - Two small cleanups # # s390: # - Fallout from the hugetlbfs support: pfmf interpretion and locking # - VSIE: fix keywrapping for nested guests # # PPC: # - Fix a bug where pages might not get marked dirty, causing guest # memory corruption on migration # - Fix a bug causing reads from guest memory to use the wrong guest # real address for very large HPT guests (>256G of memory), leading # to failures in instruction emulation. # # x86: # - Fix out of bound access from malicious pv ipi hypercalls # (introduced in rc1) # - Fix delivery of pending interrupts when entering a nested guest, # preventing arbitrarily late injection # - Sanitize kvm_stat output after destroying a guest # - Fix infinite
