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@xxxxxxxxxxxxx
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,
