BUG with proposed fix Re: [uml-devel] Can't compile under vanilla 2.6.11

[Ian McDonald <imcdnzl@gmail.com>]

OK after much further investigation, redownloading of source
(2.6.11.4) and looking at what you have said I know why it is
breaking....

I had assumed (wrongly of course) that ARCH_SYSCALLS was a one line
symbol definition but it is much more than this.

The problem occurs because in both
arch/um/include/sysdep-i386/syscalls.h and in
arch/um/kernel/sys_call_table.c a number of the elements are defined
in BOTH files.

I presume the reason why this doesn't break others systems is that
they are not using the same version of gcc as me (2.95.4). I would
guess that with a later gcc in an enum you can redefine an element and
it doesn't complain...

Anyway I believe the proper fix is to delete the lines from
arch/um/kernel/sys_call_table.c and here is a patch to do that:

255d254
< 	[ __NR_statfs64 ] = (syscall_handler_t *) sys_statfs64,
258,260d256
< 	[ __NR_utimes ] = (syscall_handler_t *) sys_utimes,
< 	[ __NR_fadvise64_64 ] = (syscall_handler_t *) sys_fadvise64_64,
< 	[ __NR_vserver ] = (syscall_handler_t *) sys_vserver,

Can somebody verify that and if correct submit to whoever (this is my
first ever attempt at fixing something in the kernel so not quite sure
what to do next!!)

Regards,

Ian

PS still have some linking issues and I will report on them as I work
out why....
