The problem is that the garbage collector for the 'host' structures
nlm_gc_hosts(), holds nlm_host_mutex while calling down to
nlmsvc_mark_resources, which, eventually takes the file->f_mutex.
We cannot therefore call nlmsvc_lookup_host() from within

humm... I think, it'd be safer to have something like the following
change in place.
The thing is that __pick_next_entity() must never be called when
first_fair(cfs_rq) == NULL. It wouldn't be a problem, should 'run_node'
be the very first field of 'struct sched_entity' (and it's the second).

Just to clarify, this is for when we use mknod to create normal,
non-device files, right? Your fix looks very correct to me.
I get this at umount, if there was a failed open():
WARNING: at fs/namespace.c:586 __mntput()
I think the problem is that may_open() calls mnt_want_write(), but if
open doesn't succeed, mnt_drop_write() will not be called.

- Support for all compound functions for virtual compound pages
(including the compound_nth_page() necessary for LBS mmap support)
- 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.

The page array is repeatedly indexed both in vunmap and vmalloc_area_node().
Add a temporary variable to make it easier to read (and easier to patch
later).

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 rel
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.

SLAB_VFALLBACK can be specified for selected slab caches. If fallback is
available then the conservative settings for higher order allocations are
overridden. We then request an order that can accomodate at mininum
100 objects. The size of an individual slab allocation is allowed to reach
up to 256
If we are in an interrupt context then simply defer the free via a workqueue.
Removing a virtual mappping *must* be done with interrupts enabled
since tlb_xx functions are called that rely on interrupts for
processor to processor communications.

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
Virtual fallbacks are rare and thus subtle bugs may creep in if we do not
test the fallbacks. CONFIG_VFALLBACK_ALWAYS makes all GFP_VFALLBACK
allocations fall back to virtual mapping.

Sparsemem currently attempts first to do a physically contiguous mapping
and then falls back to vmalloc. The same thing can now be accomplished
using GFP_VFALLBACK.
