of the Intel IXP4xx networking processor series.
Supported ciphers: des, des3, aes
and a combination of them with md5 and sha1 hmac

Add support for the SEC available on a wide range of PowerQUICC devices,
e.g. MPC8349E, MPC8548E.
This initial version supports authenc(hmac(sha1),cbc(aes)) for use with IPsec.

Patch to add checking of DES3 test vectors using CBC mode. FIPS-140-2
compliance mandates that any supported mode of operation must include a self
test. This satisfies that requirement for cbc(des3_ede). The included test
vector was generated by me using openssl. Key/IV was generated with the
following command:
openssl enc -des_ede_cbc -P
input and output values were generated by repeating the string "Too many
secrets" a few times over, truncating it to 128 bytes, and encrypting it with
openssl using the aformentioned key. Tested successfully by myself

This patch converts the relevant code in the rmd implementations to
use the pointer form of the endian swapping operations. This allows
certain architectures to generate more optimised code. For example,
on sparc64 this more than halves the CPU cycles on a typical hashing
operation.
Based on a patch by David Miller.

Check whether the destination buffer is written to beyond the last
byte contained in the scatterlist.

This triggers a corruption in the HIFN driver and doesn't seem to

Move command descriptor setup to seperate function as preparation
for the following DMA setup fixes.
Note 1: also fix a harmless typo while moving it: sa_idx is initialized
to dma->resi instead of dma->cmdi.
Note 2: errors from command descriptor setup are not propagated back,
anymore, they can't be handled anyway and all conditions leading
to errors should be checked earlier.

When the CryptoAPI instantiates a new algorithm, it performs a lookup
by driver name. Since hifn uses the same name for all modes of one
algorithm, the lookup may return an incorrect algorithm.
Change the name to use <mode>-<algo>-<devicename> to provide unique
names for the different combinations and devices.

The check for misalignment of the scatterlist data has two bugs:
- the source buffer doesn't need to be aligned at all
- the destination buffer and its size needs to be aligned to a multiple
of 4, not to the crypto alg blocksize
Introduce symbolic constant for destination buffer alignment requirements,
use it instead of the crypto alg blocksize and remove the unnecessary
checks for source buffer alignment and change cra_alignmask to zero.

The change to iwch_provider.c in commit f4e91eb4 ("IB: convert struct
class_device to struct device") undid the fix done in commit 7f049f2f
("RDMA/cxgb3: Hold rtnl_lock() around ethtool get_drvinfo call"). It
removed the calls to rtnl_lock() that serialized the iw_cxgb3 ethtool
ops calls into the cxgb3 driver. This locking is needed to avoid
messing up the internal state of the cxgb3 driver.

invalidate_inode_pages2_range() takes page offset arguments, not byte
ranges.
Another thought is that individual pages might perhaps get evicted by VM
pressure, in which case we might perhaps want to re-read not only the
evicted page, but all subsequent pages too (in case the server returns
more/less data per page so that the alignment of the next entry
changes). We should therefore remove the condition that we only do this on
page->index==0.

Create Dirty Exclusive cache line operations even if only part of the
cache line was filled. This change avoids generating cache operations,
if only part of the cache line size is copied in one loop. It also
