# HEAD: 41f45fb045bcc20e71eb705b361356e715682162 x86/asm: Make <asm/asm.h> valid on cross-builds as well
Changes for this cycle:
- 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
Thanks,
Ingo
------------------>
H. Peter Anvin (1):
x86/regs: Syscall_get_nr() returns -1 for a non-system call
H. Peter Anvin (Intel) (8):
x86/asm: Have the __ASM_FORM macros handle commas in arguments
x86/asm: Add _ASM_BYTES() macro for a .byte ... opcode sequence
x86/asm: Use _ASM_BYTES() in <asm/nops.h>
x86/entry: Unify definitions from <asm/calling.h> and <asm/ptrace-abi.h>
x86/entry: Reverse arguments to do_syscall_64()
x86/syscall: Unconditionally prototype {ia32,x32}_sys_call_table[]
x86/syscall: Maximize MSR_SYSCALL_MASK
x86/entry: Split PUSH_AND_CLEAR_REGS into two submacros
