| Subject: [PATCH] i386/bits/syscalls.h: allow immediate values as 6th syscall |
| arg |
| |
| Allow use of immedate values as the 6th syscall argument. Otherwise we must |
| store the arg on memory. This gives gcc more options to optimize better. |
| |
| This also works around an issue with posix_fallocate. |
