| H A D | calling.h | f7bafa2b Sun Feb 11 04:49:44 CST 2018 Dominik Brodowski <linux@dominikbrodowski.net> x86/entry/64: Interleave XOR register clearing with PUSH instructions
Same as is done for syscalls, interleave XOR with PUSH instructions
for exceptions/interrupts, in order to minimize the cost of the
additional instructions required for register clearing.
