Subject[PATCH 0/3] x86/pti-ish syscall cleanups
Date
Three changes in here:
- Get rid of the SYSCALL64 fast path as suggested by Linus.

- Move TS_COMPAT into the same cacheline as thread_info::flags, also
suggested by Linus.

- Document SYSCALL_DEFINE a bit better.

Andy Lutomirski (3):
x86/entry/64: Remove the SYSCALL64 fast path
x86/asm: Move 'status' from thread_struct to thread_info
syscalls: Add a bit of documentation to __SYSCALL_DEFINE
