| H A D | calling.h | 30907fd1 Sun Feb 11 04:49:46 CST 2018 Dominik Brodowski <linux@dominikbrodowski.net> x86/entry/64: Use PUSH_AND_CLEAN_REGS in more cases
entry_SYSCALL_64_after_hwframe() and nmi() can be converted to use
PUSH_AND_CLEAN_REGS instead of opencoded variants thereof. Due to
the interleaving, the additional XOR-based clearing of R8 and R9
in entry_SYSCALL_64_after_hwframe() should not have any noticeable
negative implications.
