Aneesh Kumar K.V 85e0df240e fs/9p: Make sure we properly instantiate dentry.
For lookup if we get ENOENT error from the server we still
instantiate the dentry. We need to make sure we have dentry
operations set in that case so that a later dput on the dentry
does the expected. Without the patch we get the below error

#ln  -sf abc abclink
ln: creating symbolic link `abclink': No such file or directory

Now on the host do
$ touch abclink

Guest now gives ENOENT error.
# ls

Minchan Kim 6b65aaf302 slub: Use alloc_pages_exact_node() for page allocation
The alloc_slab_page() in SLUB uses alloc_pages() if node is '-1'.  This means
that node validity check in alloc_pages_node is unnecessary and we can use
alloc_pages_exact_node() to avoid comparison and branch as commit
6484eb3e2a ("page allocator: do not check NUMA node ID when the caller
knows the node is valid") did for the page allocator.

Eric Dumazet bbd7d57bfe slub: Potential stack overflow
I discovered that we can overflow stack if CONFIG_SLUB_DEBUG=y and use slabs
with many objects, since list_slab_objects() and process_slab() use
DECLARE_BITMAP(map, page->objects).

With 65535 bits, we use 8192 bytes of stack ...

Switch these allocations to dynamic allocations.

Also fixed up one line in arch/powerpc/kernel/vio.c to use the

Grant Likely 44504b2beb of: change of_match_device to work with struct device
The of_node pointer is now stored directly in struct device, so
of_match_device() should work with any device, not just struct of_device.

This patch changes the interface to of_match_device() to accept a
struct device instead of struct of_device.

Grant Likely 4018294b53 of: Remove duplicate fields from of_platform_driver
.name, .match_table and .owner are duplicated in both of_platform_driver
and device_driver.  This patch is a removes the extra copies from struct
of_platform_driver and converts all users to the device_driver members.

This patch is a pretty mechanical change.  The usage model doesn't change
and if any drivers have been missed, or if anything has been fixed up
incorrectly, then it will fail with a compile time error, and the fixup
will be trivial.  This patch looks big and scary because it touches so
many files, but it should be pretty safe.

This patch allows any driver to provide an OF match table when CONFIG_OF
