[Xen-devel] [PATCH 0/3] x86: XSA-109/110 follow-up (to be considered for 4.5)

["Jan Beulich" <JBeulich@xxxxxxxx>]

1: tighten page table owner checking in do_mmu_update()
2: don't ignore foreigndom input on various MMUEXT ops
3: HVM: don't crash guest upon problems occurring in user mode

Reason to request considering this for 4.5: Tightened argument
checking (as done in the first two patches) reduces the chances
of them getting abused. Not unduly crashing the guest (as done
in the third one) may avoid future security issues of guest user
mode affecting the guest kernel.
