This patch removes the crashkernel parsing from arch/sh/kernel/machine_kexec.c

Yes.
I'm curious, do you have a normal program that uses mknod(2) this way?

- Support for all compound functions for virtual compound pages

- Fix various bugs
- Fix i386 build
Currently there is a strong tendency to avoid larger page allocations in
the kernel because of past fragmentation issues
We already have page table manipulation for vmalloc in vmalloc.c. Move the
vmalloc_to_page() function there as well.
Move the definitions for vmalloc related functions in mm.h to before the
functions dealing with compound pages because they will soon need to use
them.

Make vmalloc functions work the same way as kfree() and friends that
take a const void * argument.

pgtable.h does not include highmem.h but uses various constants from
highmem.h. We cannot include highmem.h because highmem.h will in turn
include many other include files that also depend on pgtable.h
So move the definitions from highmem.h into pgtable.h.

Make vunmap return the page array that was used at vmap. This is useful
if one has no structures to track the page array but simply stores the
virtual address somewhere. The disposition of the page array can be
decided upon after vunmap. vfree() may now also be used instead of
vunmap which will
Sometimes we need to figure out which vmalloc address is in use
for a certain page struct. There is no easy way to figure out
the vmalloc address from the page struct. So simply search through
the kernel page tables to find the address. This is a fairly expensive
process. Use sparingly (or provide
Currently vmalloc is used for the zone wait table possibly generating the need
to generate lots of TLBs to access the tables. We can now use GFP_VFALLBACK to
attempt the use of a physically contiguous page that can then use the large
kernel TLBs.

This is in particular useful for large I/Os because it will allow 100
allocs from the SLUB fast path without having to go to the page allocator.

SLAB_VFALLBACK can be specified for selected slab caches. If fallback is

In an interrupt context we cannot wait for the vmlist_lock in
__get_vm_area_node(). So use a trylock instead. If the trylock fails
then the atomic allocation will fail and subsequently be retried.
This only works because the flush_cache_vunmap in use for
allocation is never performing any IPIs in
