   3 Subject: [PATCH] i386/bits/syscalls.h: allow immediate values as 6th syscall
   4  arg
   5
   6 Allow use of immedate values as the 6th syscall argument. Otherwise we must
   7 store the arg on memory. This gives gcc more options to optimize better.
   8
   9 This also works around an issue with posix_fallocate.
