[Xen-devel] [PATCH v2 for-4.7 0/5] Fixes for invlpg handling for HVM guests

[Andrew Cooper <andrew.cooper3@xxxxxxxxxx>]

Turns out there are a lot of broken corner cases.

Changes in v2:
 * Some improvements to commit messages
 * Split part of the original patch 4 out, to make the new patch 5 clearer
 * Add vcpu parameter to new invlpg() function, and avoid assuming 'current'
 * Modify paging_invlpg() to be void, and issue the PV TLB flush as well

Andrew Cooper (5):
  x86/hvm: Always return the linear address from
    hvm_virtual_to_linear_addr()
  x86/hvm: Raise #SS faults for %ss-based segmentation violations
  x86/hvm: Correct the emulated interaction of invlpg with segments
  x86/svm: Don't unconditionally use a new ASID in
    svm_invlpg_intercept()
  x86/hvm: Fix invalidation for emulated invlpg instructions
