Subject: [PATCH v2 0/4] vmalloc: Improve vmalloc(4MB) performance

I may have gone a little too far with the first patch.  It turns out we
have a lot of code using the vmalloc caller functionality, and I decided
to convert it all to unsigned long instead of leaving some paths as void *
and casting later.

I can redo that if necessary.  I've tested arm32, sh4 and powerpc32 builds
as well as x86, but I wouldn't be surprised if the buildbots tell me I
missed something.

Matthew Wilcox (Oracle) (4):
  mm/vmalloc: Change the 'caller' type to unsigned long
  mm/util: Add kvmalloc_node_caller
  mm/vmalloc: Use kvmalloc to allocate the table of pages
  MAINTAINERS: Add Vlad Rezki as vmalloc maintainer
