[patch 3/7] uml: fix syscall table by including $(SUBARCH)'s one, for x86-64

From: blaisorblade
Date: Sun Apr 24 2005 - 13:59:39 EST

Next message: blaisorblade: "[patch 6/7] uml: commentary about forking flag"
Previous message: blaisorblade: "[patch 1/7] uml: fix syscall table by including $(SUBARCH)'s one, for i386"
Messages sorted by: [ date ] [ thread ] [ subject ] [ author ]

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.
