macro for transformation.

Please drop this patch Julia.

I misunderstood what you suggested and it works fine using
`--macro-file` flag:

himanshu@himanshu-Vostro-3559:~/zephyr$ cat mymacros.h; spatch --sp-file test.cocci drivers/dma/dma_handlers.c --macro-file mymacros.h
#define Z_SYSCALL_HANDLER int xxx
init_defs_builtins: /usr/local/bin/../lib/coccinelle/standard.h
init_defs: mymacros.h
HANDLING: drivers/dma/dma_handlers.c
_impl_dma_start
_impl_dma_stop


Sorry for the noise.
