[PATCH] uml: fix syscall table by including $(SUBARCH)'s one, for x86-64
Reuse asm-x86-64/unistd.h to build our syscall table, like x86-64 already does. Like for i386, we must add some #defines for all the (right!) changes UML does to x86-64 syscall table. Note: I noted a bogus: [ __NR_sched_yield ] = (syscall_handler_t *) yield, while doing this patch (which could only be a workaround for some strange bug, but I would ignore this possibility). I'm changing this without notice. Signed-off-by: Paolo 'Blaisorblade' Giarrusso <blaisorblade@yahoo.it> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
