From ddcd6b175793839e51fdd55debb670a9f512c448 Mon Sep 17 00:00:00 2001 From: Paolo 'Blaisorblade' Giarrusso Date: Sun, 1 May 2005 08:58:55 -0700 Subject: [PATCH] uml: quick fix syscall table for x86_64 Fix the moved syscall table for the x86_64 SUBARCH: - redirect __NR_chown and such to versions aware of 32-bit UIDs, - avoid the useless hack for sys_nfsservctl, - use sys_sendfile64 in the table rather than sys_sendfile. - __NR_uselib is sys_ni_syscall on x86_64 (which does not support A.OUT). - __NR_getrlimit is sys_getrlimit, not sys_old_getrlimit Signed-off-by: Paolo 'Blaisorblade' Giarrusso Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds --- arch/um/sys-x86_64/sys_call_table.c | 53 +++++++++++++++++-------------------- 1 file changed, 24 insertions(+), 29 deletions(-) (limited to 'arch/um') diff --git a/arch/um/sys-x86_64/sys_call_table.c b/arch/um/sys-x86_64/sys_call_table.c index 3f5efbfb46d..a31e0dffb27 100644 --- a/arch/um/sys-x86_64/sys_call_table.c +++ b/arch/um/sys-x86_64/sys_call_table.c @@ -14,12 +14,6 @@ #include "sysdep/syscalls.h" #include "kern_util.h" -#ifdef CONFIG_NFSD -#define NFSSERVCTL sys_nfsservctl -#else -#define NFSSERVCTL sys_ni_syscall -#endif -
