Subject: [patch V4 00/15] entry, x86, kvm: Generic entry/exit functionality
 for host and guest

This is the 4rd version of generic entry/exit functionality for host and
guest.

The 3rd version is available here:

    https://lore.kernel.org/r/20200716182208.180916541@linutronix.de

Changes vs. V3:

  - Drop the architecture wrappers for seccomp and audit (Kees)
  - Move the user return notifier out of the loop
  - Bring I/O bitmap handling back
  - Use the existing helpers to get syscall number and return value
  - Drop dummy defines for SYSCALL_TRACE and NOTIFY_RESUME as all
    architectures define them
  - Fix TIF_SYSCALL_AUDIT dummy define
  - Adjust comments

The patches depend on:

    git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git x86/entry

The lot is also available from git:

    git://git.kernel.org/pub/scm/linux/kernel/git/tglx/devel.git x86/entry

Thanks,

	tglx
