It is a frequent mistake to confuse the netlink port identifier with a
process identifier. Try to reduce this confusion by renaming fields
that hold port identifiers portid instead of pid.
I have carefully avoided changing the structures exported to
userspace to avoid changing the userspace API.
I have successfully built an allyesconfig kernel with this change.

This patch defines netlink_kernel_create as a wrapper function of
__netlink_kernel_create to hide the struct module *me parameter
(which seems to be THIS_MODULE in all existing netlink subsystems).

This reverts commit e6ccc727f30a02670f6a00df6d548942bc988f43.
Above commit caused performance regression for CAST6. Reverting gives
following increase in tcrypt speed tests (revert-vs-old ratios).

This patch add the 842 cryptographic API driver that
submits compression requests to the 842 hardware compression
accelerator driver (nx-compress).
If the hardware accelerator goes offline for any reason
(dynamic disable, migration, etc...), this driver will use LZO
as a software failover for all future compression requests.
For decompression requests, the 842 hardware driver contains
a software implementation of the 842 decompressor to support
the decompression of data that was compressed before the accelerator
went offline.

This patch adds a x86_64/avx assembler implementation of the Cast6 block
cipher. The implementation processes eight blocks in parallel (two 4 block
chunk AVX operations). The table-lookups are done in general-purpose registers.
For small blocksizes the functions from the generic module are called. A good
performance increase is provided for blocksizes greater or equal to 128B.
Patch has been tested with tcrypt and automated filesystem tests.

This patch adds the following structure:
struct netlink_kernel_cfg {
unsigned int groups;
void (*input)(struct sk_buff *skb);
struct mutex *cb_mutex;
};
That can be passed to netlink_kernel_create to set optional configurations
for netlink kernel sockets.
I've populated this structure by looking for NULL and zero parameters at the
existing code. The remaining parameters that always need to be set are still
left in the original interface.
That includes optional parameters for the netlink socket creation. This allows
easy extensibility of this interface in the future.
This patch also adapts all callers to use this new interface.

It has been observed that sometimes the crypto allocation code
will get stuck for 60 seconds or multiples thereof. This is
usually caused by an algorithm failing to pass the self-test.
If an algorithm fails to be constructed, we will immediately notify
all larval waiters. However, if it succeeds in construction, but
then fails the self-test, we won't notify anyone at all.
This patch fixes this by merging the notification in the case
where the algorithm fails to be constructed with that of the
the case where it pases the self-test. This way regardless of
what happens, we'll give the larval waiters an answer.

This patch changes u8 in struct arc4_ctx and variables to u32 (as AMD seems
to have problem with u8 array). Below are tcrypt results of old 1-byte block
cipher versus ecb(arc4) with u8 and ecb(arc4) with u32.
tcrypt results, x86-64 (speed ratios: new-u32/old, new-u8/old):
u32 u8
AMD Phenom II : x3.6 x2.7
Intel Core 2 : x2.0 x1.9
tcrypt results, i386 (speed ratios: new-u32/old, new-u8/old):
u32 u8
Intel Atom N260 : x1.5 x1.4
