Mateusz Guzik f0648bcc04 amd64: get rid of the pessimized bcopy in syscall arg copy ... The code was unnecessarily conditionally copying either 5 or 6 args. It can blindly copy 6, which also means the size is known at compilation time and the operation can be depessimized. Note the entire syscall handling code is rather slow. Tested on Skylake, sample result for getppid (calls/s): without pti: 7310106 -> 10653569 with pti: 3304843 -> 4148306 Some syscalls (like read) did not note any difference, other have typically very modest wins.		2018-05-04 04:05:07 +00:00
