Anton Blanchard dc4fbba11e powerpc: Create disable_kernel_{fp,altivec,vsx,spe}()
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.

Kim Phillips 3265c4babe crypto: powerpc - move files to fix build error
The current cryptodev-2.6 tree commits:

d9850fc529 ("crypto: powerpc/sha1 - kernel config")
50ba29aaa7 ("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.
