powerpc: Create disable_kernel_{fp,altivec,vsx,spe}()

2015-12-01T02:52:25+00:00

The enable_kernel_*() functions leave the relevant MSR bits enabled
until we exit the kernel sometime later. Create disable versions
that wrap the kernel use of FP, Altivec VSX or SPE.

While we don't want to disable it normally for performance reasons
(MSR writes are slow), it will be used for a debug boot option that
does this and catches bad uses in other areas of the kernel.

crypto: powerpc/md5 - use md5 IV MD5_HX instead of their raw value

2015-05-18T04:20:20+00:00

Since MD5 IV are now available in crypto/md5.h, use them.

crypto: powerpc - move files to fix build error

2015-03-09T10:06:19+00:00

The current cryptodev-2.6 tree commits:

d9850fc529ef ("crypto: powerpc/sha1 - kernel config")
50ba29aaa7b0 ("crypto: powerpc/sha1 - glue")

failed to properly place files under arch/powerpc/crypto, which
leads to build errors:

make[1]: *** No rule to make target 'arch/powerpc/crypto/sha1-spe-asm.o', needed by 'arch/powerpc/crypto/sha1-ppc-spe.o'.  Stop.
make[1]: *** No rule to make target 'arch/powerpc/crypto/sha1_spe_glue.o', needed by 'arch/powerpc/crypto/sha1-ppc-spe.o'.  Stop.
Makefile:947: recipe for target 'arch/powerpc/crypto' failed

Move the two sha1 spe files under crypto/, and whilst there, rename
other powerpc crypto files with underscores to use dashes for
consistency.

crypto: powerpc/md5 - glue

Glue code for crypto infrastructure. Call the assembler
code where required. Take a little care about small input
data. Kick out early for input chunks < 64 bytes and replace
memset for context cleanup with simple loop.

crypto: powerpc/md5 - assembler

2015-03-04T09:12:40+00:00

This is the assembler code for the MD5 implementation.
Handling of algorithm constants has been slightly
changed to reduce register usage and make better use
of cores with multiple ALUs. Thus they are stored as
delta values.
