Subject: [PATCH v2 0/5] x86: Lift create_exception_frame() up out of C
Date: Tue, 27 Feb 2018 14:50:31 +0000	[thread overview]
Message-ID: <1519743036-11600-1-git-send-email-andrew.cooper3@citrix.com> (raw)

This has finally undergone performance testing.  No measureable difference in
any lmbench test on either 32 or 64bit PV guests.

Andrew Cooper (5):
  x86/entry: Correct comparisons against boolean variables
  x86/pv: Drop int80_bounce from struct pv_vcpu
  x86/pv: Introduce pv_create_exception_frame()
  x86/pv: Drop {compat_,}create_bounce_frame() and use the C version instead
  x86/pv: Implement the failsafe callback using the general path
