Hi all,

---[ end trace 49ed8f97d467e164 ]---
Kernel panic - not syncing: Attempted to kill init! exitcode=0x00000005
-----------------------------------------------------------------------------
The BUG is:
BUG_ON(page_shift != PAGE_SIZE);
in the !CONFIG_HAVE_ARCH_HUGE_VMAP version of vmap_hpages_range().
I am guessing this is something to do with the vmalloc changes in Andrew's
patches (or it could be the fixup I did to Nick's patch).
I have reverted
c353e2997976 ("mm/vmalloc: hugepage vmalloc mappings")
a826492f28d9 ("mm: move ioremap page table mapping function to mm/")
(and my fix up) for today and things seem to work (if only because the
BUG() has been removed :-)).

Good to know, maybe I didn't test powerpc without later enabling
patches...
The series also has a compile bug on ARM I have to work out, so
yeah drop those for now, I'll post a v2. The large system map patches
that I posted in that series can stay I think.
Thanks,
Nick

OK, I have removed them from the akpm-current tree today.

That fixes it for me. I will use that in linux-next today instead of
the reverts.

And to be clear I reproduced the issue and this patch fixes it for me
