Sage Weil bba7881954 mm: remove broken 'kzalloc' mempool
The kzalloc mempool zeros items when they are initially allocated, but
does not rezero used items that are returned to the pool.  Consequently
mempool_alloc()s may return non-zeroed memory.

Since there are/were only two in-tree users for
mempool_create_kzalloc_pool(), and 'fixing' this in a way that will
re-zero used (but not new) items before first use is non-trivial, just
remove it.

Matthew Dobson f183323d38 [PATCH] mempool: add kzalloc allocator
Add another allocator to the common mempool code: a kzalloc/kfree allocator

This will be used by the next patch in the series to replace a mempool-backed
kzalloc allocator.  It is also very likely that there will be more users in
the future.

Matthew Dobson 53184082b0 [PATCH] mempool: add kmalloc allocator
Add another allocator to the common mempool code: a kmalloc/kfree allocator

This will be used by the next patch in the series to replace duplicate
mempool-backed kmalloc allocators in several places in the kernel.  It is also
very likely that there will be more users in the future.

Matthew Dobson 6e0678f394 [PATCH] mempool: add page allocator
This will be used by the next patch in the series to replace duplicate
mempool-backed page allocators in 2 places in the kernel.  It is also likely
that there will be more users in the future.

Al Viro dd0fc66fb3 [PATCH] gfp flags annotations - part 1
- added typedef unsigned int __nocast gfp_t;

 - replaced __nocast uses for gfp flags with gfp_t - it gives exactly
   the same warnings as far as sparse is concerned, doesn't change
   generated code (from gcc point of view we replaced unsigned int with
   typedef) and documents what's going on far better.

Christoph Lameter 1946089a10 [PATCH] NUMA aware block device control structure allocation
Patch to allocate the control structures for for ide devices on the node of
the device itself (for NUMA systems).  The patch depends on the Slab API
change patch by Manfred and me (in mm) and the pcidev_to_node patch that I
posted today.

Does some realignment too.

Linus Torvalds 1da177e4c3 Linux-2.6.12-rc2
Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
