Merge tag 'x86-asm-2021-06-28' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull x86 asm updates from Ingo Molnar:
- Micro-optimize and standardize the do_syscall_64() calling convention
- Make syscall entry flags clearing more conservative
- Clean up syscall table handling
- Clean up & standardize assembly macros, in preparation of FRED
- Misc cleanups and fixes

x86/entry: Split PUSH_AND_CLEAR_REGS into two submacros
x86/syscall: Maximize MSR_SYSCALL_MASK
x86/syscall: Unconditionally prototype {ia32,x32}_sys_call_table[]
x86/entry: Reverse arguments to do_syscall_64()
x86/entry: Unify definitions from <asm/calling.h> and <asm/ptrace-abi.h>
