Looking at your 2nd patch, '[PATCH 2/3] The syscall defines were not
compatible with older kernels, namely 3.0.x', this bit doesn't seem
correct at all:

Including <asm-generic/syscall.h> is highly suspicious. Did you try to
include <asm/syscall.h> and get errors? If so, we can work to fix those
errors. Not including your arch's real syscall.h file will cause errors
down the road.
