Change x86 crypto implementations to use ENTRY()/ENDPROC() as linux/linkage.h 
recommends use of ENDPROC() for assembler functions.

While at it, also change jump targets to local labels for some implementations.

Jussi Kivilinna (12):
      crypto: x86/aes - assembler clean-ups: use ENTRY/ENDPROC, localize jump targets
      crypto: aesni-intel - add ENDPROC statements for assembler functions
      crypto: blowfish-x86_64: use ENTRY()/ENDPROC() for assembler functions and localize jump targets
