The upcomming crypto user configuration api needs to identify
crypto instances. This patch adds a flag that is set if the
algorithm is an instance that is build from templates.

Patch adds 3-way parallel x86_64 assembly implementation of twofish as new
module. New assembler functions crypt data in three blocks chunks, improving
cipher performance on out-of-order CPUs.
Patch has been tested with tcrypt and automated filesystem tests.
Summary of the tcrypt benchmarks:
Twofish 3-way-asm vs twofish asm (128bit 8kb block ECB)
encrypt: 1.3x speed
decrypt: 1.3x speed
Twofish 3-way-asm vs twofish asm (128bit 8kb block CBC)
encrypt: 1.07x speed
decrypt: 1.4x speed
Twofish 3-way-asm vs twofish asm (128bit 8kb block CTR)
encrypt: 1.4x speed
Twofish 3-way-asm vs AES asm (128bit 8kb block ECB)

This needed by 3-way twofish patch to be able to easily use one block
assembler functions. As glue code is shared between i586/x86_64 apply
change to i586 assembler too. Also export assembler functions for
3-way parallel twofish module.

This patch adds improved F-macro for 4-way parallel functions. With new
F-macro for 4-way parallel functions, blowfish sees ~15% improvement in
speed tests on AMD Phenom II (~5% on Intel Xeon E7330).
However when used in 1-way blowfish function new macro would be ~10%
slower than original, so old F-macro is kept for 1-way functions.
Patch cleans up old F-macro as it is no longer needed in 4-way part.
Patch also does register macro renaming to reduce stack usage.

Patch adds x86_64 assembly implementation of blowfish. Two set of assembler
functions are provided. First set is regular 'one-block at time'
encrypt/decrypt functions. Second is 'four-block at time' functions that
gain performance increase on out-of-order CPUs. Performance of 4-way
functions should be equal to 1-way functions with in-order CPUs.

As cryptd is depeneded on by other algorithms such as aesni-intel,
it needs to be registered before them. When everything is built
as modules, this occurs naturally. However, for this to work when
they are built-in, we need to use subsys_initcall in cryptd.

This is an assembler implementation of the SHA1 algorithm using the
Supplemental SSE3 (SSSE3) instructions or, when available, the
Advanced Vector Extensions (AVX).
Testing with the tcrypt module shows the raw hash performance is up to
2.3 times faster than the C implementation, using 8k data blocks on a
Core 2 Duo T5500. For the smalest data set (16 byte) it is still 25%
faster.
Since this implementation uses SSE/YMM registers it cannot safely be
used in every situation, e.g. while an IRQ interrupts a kernel thread.
The implementation falls back to the generic SHA1 variant, if using
the SSE/YMM registers is not possible.
With this algorithm I was able to increase the throughput of a single
IPsec link from 344 Mbit/s to 464 Mbit/s on a Core 2 Quad CPU using
the SSSE3 variant -- a speedup of +34.8%.
Saving and restoring SSE/YMM state might make the actual throughput
fluctuate when there are FPU intensive userland applications running.
For example, meassuring the performance using iperf2 directly on the
machine under test gives wobbling numbers because iperf2 uses the FPU
for each packet to check if the reporting interval has expired (in the
above test I got min/max/avg: 402/484/464 MBit/s).
Using this algorithm on a IPsec gateway gives much more reasonable and
stable numbers, albeit not as high as in the directly connected case.
Here is the result from an RFC 2544 test run with a EXFO Packet Blazer
FTB-8510:
frame size sha1-generic sha1-ssse3 delta
64 byte 37.5 MBit/s 37.5 MBit/s 0.0%
128 byte 56.3 MBit/s 62.5 MBit/s +11.0%
256 byte 87.5 MBit/s 100.0 MBit/s +14.3%
512 byte 131.3 MBit/s 150.0 MBit/s +14.2%
1024 byte 162.5 MBit/s 193.8 MBit/s +19.3%
1280 byte 175.0 MBit/s 212.5 MBit/s +21.4%
1420 byte 175.0 MBit/s 218.7 MBit/s +25.0%
1518 byte 150.0 MBit/s 181.2 MBit/s +20.8%
The throughput for the largest frame size is lower than for the
previous size because the IP packets need to be fragmented in this
case to make there way through the IPsec tunnel.

Export the update function as crypto_sha1_update() to not have the need
to reimplement the same algorithm for each SHA-1 implementation. This
way the generic SHA-1 implementation can be used as fallback for other
implementations that fail to run under certain circumstances, like the
need for an FPU context while executing in IRQ context.

When loading aes via the module alias, a padlock module failing to
load due to missing hardware is not particularly notable. With
v2.6.27-rc1~1107^2~14 (crypto: padlock - Make module loading quieter
when hardware isn't available, 2008-07-03), the padlock-aes module
suppresses the relevant messages when the "quiet" flag is in use; but
better to suppress this particular message completely, since the
administrator can already distinguish such errors by the absence of a
message indicating initialization failing or succeeding.
This avoids occasional messages in syslog of the form
padlock_aes: VIA PadLock not detected.

exit_mm() sets ->mm == NULL then it does mmput()->exit_mmap() which
frees the memory.
However select_bad_process() checks ->mm != NULL before TIF_MEMDIE,
so it continues to kill other tasks even if we have the oom-killed
task freeing its memory.
Change select_bad_process() to check ->mm after TIF_MEMDIE, but skip
the tasks which have already passed exit_notify() to ensure a zombie
with TIF_MEMDIE set can't block oom-killer. Alternatively we could
probably clear TIF_MEMDIE after exit_mmap().

The first packet that gdb sends when the kernel is in kdb mode seems
to change with every release of gdb. Instead of continuing to add
many different gdb packets, change kdb to automatically look for any
thing that looks like a gdb packet.
Example 1 cold start test:
echo g > /proc/sysrq-trigger
$D#44+
Example 2 cold start test:
echo g > /proc/sysrq-trigger
$3#33
The second one should re-enter kdb's shell right away and is purely a

When switching from kdb mode to kgdb mode packets were getting lost
depending on the size of the fifo queue of the serial chip. When gdb
initially connects if it is in kdb mode it should entirely send any
character buffer over to the gdbstub when switching connections.
Previously kdb was zero'ing out the character buffer and this could
lead to gdb failing to connect at all, or a lengthy pause could occur
on the initial connect.

Move reading to separate function and remove csocket variable.
Also change semantic in a little: goto incomplete_rcv only when
we get -EAGAIN (or a familiar error) while reading rfc1002 header.
In this case we don't check for echo timeout when we don't get whole
header at once, as it was before.

Introduce new helper functions which try kmalloc, and then fall back
to vmalloc if necessary, and use them for allocating and deallocating
s_flex_groups.
