CC: Andi Kleen <[email protected]>
I'm resending this patch again for 4th time since it wasn't merged nor it is
in -mm. The first time it didn't look right because of Andi looking at an
older tree, but it later was sorted out, and he Acked the patch.
Keeping this function does not makes sense because it's a copied (and buggy)
copy of sys_time. The only difference is that now.tv_sec (which is a time_t,
i.e. a 64-bit long) is copied (and truncated) into a int (32-bit).
The prototype is the same (they both take a long __user *), so let's drop this
and redirect it to sys_time (and make sure it exists by defining
__ARCH_WANT_SYS_TIME).
Only disadvantage is that the sys_stime definition is also compiled (may be
fixed if needed by adding a separate __ARCH_WANT_SYS_STIME macro, and defining
it for all arch's defining __ARCH_WANT_SYS_TIME except x86_64).
Not compile-tested, sorry.
