  KVM: LAPIC: Fix pv ipis out-of-bounds access (2018-09-07 18:38:43 +0200)

----------------------------------------------------------------
KVM fixes for 4.19-rc3

ARM:
 - Fix a VFP 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 loop when emulating a nested guest page fault
   and improve the surrounding emulation code
 - Two minor cleanups
