vger 2.2.10 compile failures

vger 2.2.10 compile failures

[Benjamin Herrenschmidt]

I'm getting link errors when compiling today's vger 2.2.10 with xmon
support enabled:

arch/ppc/xmon/x.o: In function `backtrace':
arch/ppc/xmon/x.o(.text+0x129e): undefined reference to `ret_from_int'
arch/ppc/xmon/x.o(.text+0x12a2): undefined reference to `ret_from_syscall_1'
arch/ppc/xmon/x.o(.text+0x12a6): undefined reference to `ret_from_int'
arch/ppc/xmon/x.o(.text+0x12aa): undefined reference to `ret_from_syscall_1'
arch/ppc/xmon/x.o(.text+0x12ae): undefined reference to `ret_from_syscall_2'
arch/ppc/xmon/x.o(.text+0x12b6): undefined reference to `ret_from_syscall_2'

Apparently, the name of those symbols changed, I'll try to fix xmon here,
but maybe someone already did it (Paul ?)

BTW. Here's the patch (it compiles, I beleive it works too but I didn't
test xmon yet):

I got tricked by cvs about this, maybe you have too.  I had a stable
(linux_2_2) cvs tree, and when I did `cvs update -dP', I got an xmon
directory, but it was the xmon from the head of the tree, i.e. the
devel branch.  I should have been doing `cvs update -dP -rlinux_2_2',
of course.  If you do that it should give you the xmon from the stable
branch (which didn't actually exist until yesterday, but now has the
xmon.c with the correct contents).

Paul.
