6dcc5627f6 x86/asm: Change all ENTRY+ENDPROC to SYM_FUNC_*
These are all functions which are invoked from elsewhere, so annotate
them as global using the new SYM_FUNC_START and their ENDPROC's by
SYM_FUNC_END.

Make sure ENTRY/ENDPROC is not defined on X86_64, given these were the
last users.

b46c9d7176 crypto: x86/camellia - Fix RBP usage
Using RBP as a temporary register breaks frame pointer convention and
breaks stack traces when unwinding from an interrupt in the crypto code.

Use R12 instead of RBP.  Both are callee-saved registers, so the
substitution is straightforward.

0b95ec56ae crypto: camellia - add assembler implementation for x86_64
Patch adds x86_64 assembler implementation of Camellia block cipher. Two set of
functions are provided. First set is regular 'one-block at time' encrypt/decrypt
functions. Second is 'two-block at time' functions that gain performance increase
on out-of-order CPUs. Performance of 2-way functions should be equal to 1-way
functions with in-order CPUs.

Patch has been tested with tcrypt and automated filesystem tests.

Tcrypt benchmark results:
