For multiple buffers speed tests, the number of buffers, or
requests, used actually sets the level of parallelism a tfm
provider may utilize to hide latency. The existing number
(of 8) is good for some software based providers but not
enough for many HW providers with deep FIFOs.
Add a module parameter that allows setting the number of
multiple buffers/requests used, leaving the default at 8.

The AEAD speed test pretended to support decryption, however that support

The multi buffer ahash speed test was allocating multiple
buffers for use with the multiple outstanding requests
it was starting but never actually using them (except
to free them), instead using a different single statically
allocated buffer for all requests.
Fix this by actually using the allocated buffers for the test.
It is noted that it may seem tempting to instead remove the
allocation and free of the multiple buffers and leave things as
they are since this is a hash test where the input is read
only. However, after consideration I believe that multiple
buffers better reflect real life scenario with regard
to data cache and TLB behaviours etc.

The tcrypt AEAD cycles speed tests disables irqs during the test, which is
broken at the very least since commit
'1425d2d17f7309c6 ("crypto: tcrypt - Fix AEAD speed tests")'
adds a wait for completion as part of the test and probably since
switching to the new AEAD API.
While the result of taking a cycle count diff may not mean much on SMP
systems if the task migrates, it's good enough for tcrypt being the quick

changes return 0 for interrupted_kernel_fpu_idle() and the in_interrupt()

Thus resulting in the WARN_ON().
Remove the local_bh_disable/enable() calls around the existing

percpu.h is included by sched.h and module.h and thus ends up being
included when building most .c files. percpu.h includes slab.h which
in turn includes gfp.h making everything defined by the two files
universally available and complicating inclusion dependencies.
percpu.h -> slab.h dependency is about to be removed. Prepare for
this change by updating users of gfp and slab facilities include those
headers directly instead of assuming availability. As this conversion
needs to touch large number of source files, the following script is
used as the basis of conversion.
http://userweb.kernel.org/~tj/misc/slabh-sweep.py
The script does the followings.
* Scan files for gfp and slab usages and update includes such that
only the necessary includes are there. ie. if only gfp is used,
gfp.h, if slab is used, slab.h.
* When the script inserts a new include, it looks at the include
blocks and try to put the new include such that its order conforms
to its surrounding. It's put in the include block which contains
core kernel includes, in the same order that the rest are ordered -
alphabetical, Christmas tree, rev-Xmas-tree or at the end if there
doesn't seem to be any matching order.
* If the script can't find a place to put a new include (mostly
because the file doesn't have fitting include block), it prints out
an error message indicating which .h file needs to be added to the
file.
The conversion was done in the following steps.
1. The initial automatic conversion of all .c files updated slightly
over 4000 files, deleting around 700 includes and adding ~480 gfp.h
and ~3000 slab.h inclusions. The script emitted errors for ~400
files.
2. Each error was manually checked. Some didn't need the inclusion,
some needed manual addition while adding it to implementation .h or
embedding .c file was more appropriate for others. This step added
inclusions to around 150 files.
3. The script was run again and the output was compared to the edits
from #2 to make sure no file was left behind.
4. Several build tests were done and a couple of problems were fixed.
e.g. lib/decompress_*.c used malloc/free() wrappers around slab
APIs requiring slab.h to be added manually.
5. The script was run on all .h files but without automatically
editing them as sprinkling gfp.h and slab.h inclusions around .h
files could easily lead to inclusion dependency hell. Most gfp.h
inclusion directives were ignored as stuff from gfp.h was usually
wildly available and often used in preprocessor macros. Each
slab.h inclusion directive was examined and added manually as
necessary.
6. percpu.h was updated not to include slab.h.
7. Build test were done on the following configurations and failures
were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my
distributed build env didn't work with gcov compiles) and a few
more options had to be turned off depending on archs to make things
build (like ipr on powerpc/64 which failed due to missing writeq).
* x86 and x86_64 UP and SMP allmodconfig and a custom test config.
* powerpc and powerpc64 SMP allmodconfig
* sparc and sparc64 SMP allmodconfig
* ia64 SMP allmodconfig
* s390 SMP allmodconfig
* alpha SMP allmodconfig
* um on x86_64 SMP allmodconfig
8. percpu.h modifications were reverted so that it could be applied as
a separate patch and serve as bisection point.
Given the fact that I had only a couple of failures from tests on step
6, I'm fairly confident about the coverage of this conversion patch.
If there is a breakage, it's likely to be something in one of the arch
headers which should be easily discoverable easily on most builds of
the specific arch.

This adds the 'alg' module parameter to be able to test an
algorithm by name. If the algorithm type is not ad-hoc
clear for a algorithm (e.g. pcrypt, cryptd) it is possilbe
to set the algorithm type with the 'type' module parameter.

At present, the tcrypt module always exits with an -EAGAIN upon
successfully completing all the tests its been asked to run. In fips
mode, integrity checking is done by running all self-tests from the
initrd, and its much simpler to check the ret from modprobe for
success than to scrape dmesg and/or /proc/crypto. Simply stay
loaded, giving modprobe a retval of 0, if self-tests all pass and
we're in fips mode.
A side-effect of tracking success/failure for fips mode is that in
non-fips mode, self-test failures will return the actual failure
return codes, rather than always returning -EAGAIN, which seems more
correct anyway.
The tcrypt_test() portion of the patch is dependent on my earlier
pair of patches that skip non-fips algs in fips mode, at least to
achieve the fully intended behavior.
Nb: testing this patch against the cryptodev tree revealed a test
failure for sha384, which I have yet to look into...
