Hi Christoph,
commit e18d65f0500b95d8724b17d8ea9f1116cf390bbe
"slub: Remove static kmem_cache_cpu array for boot"
made my ARM 926 UP system hang at boot, if I revert this (have
to back out a lot of SLUB patches for that) it comes back up. (Same if I
switch to SLAB.)
Any hints on how I can get patch around this in a nice way?
Yours,
Linus Walleij

It's in -next via some means.

This is UP right? Any more details on this one? Does ARM have
earlyprintk?
Tejun also has some patches that make the percpu allocator work on UP so
that we do not need the hack (you must have the hack which is commit
c23e5ad729ac43f5e2fbc080f94cf61f07b4d45f as well to make UP work right!).
I am not sure if they are already in -next though.

Yes, they should be in linux-next. I haven't pulled the changes to
slab.git, though. Linus, do things work in linux-next if you revert
commit 5249d039500f05a5ab379286b1d23ab9b04d3f2c ("Slub: UP bandaid")?

Linus, care to retest linux-next on your configuration? The above
commit has now been replaced with proper UP per-cpu allocator support
by Tejun Heo.

For various administrative reasons I have lost contact with the hardware,
hang on and I'll retest as soon as I can!
