2.5.35 undefined reference to `wait_task_inactive'

2.5.35 undefined reference to `wait_task_inactive'

[Skip Ford]

A call to wait_task_inactive was added to fs/exec.c but that function is
not defined for UP.

I haven't seen a fix for this yet?

Err, I've done and sent a possible patch to LKML, I'm simply not sure if 
this is the right thing to do:

BTW, ACPI needs a few tunings too to be able to compile the stuff as

simply did a quick hack to have a running and bootable 2.5.35 kernel:

Actually the correct fix seems to be already in Linus' tree:

ChangeSet@1.564, 2002-09-15 22:53:19-07:00, david@gibson.dropbear.id.au
   [PATCH] Remove CONFIG_SMP around wait_task_inactive()

So after all, my patch wasn't all that wrong, just a little ... ;).

As it seems also the ieee1394 patches went in and the USB storage 
compilation problem is also fixed.

Btw, why not put the #ifdef in the header file that defines 
ACPI_MODULE_NAME(x) instead of littering more #ifdefs around code?

Right, stupid me. With that I even catch those modules I didn't 
explicitly set to 'm' in the ACPI subtree. But I guess this is up to the 
Intel guys anyway. If they don't patch it by 2.5.36 I'll submit a clean 
patch myself.
