    powerpc/crypto: Fix aes-gcm-p10 link errors · 81d358b1
    Michael Ellerman authored
    The recently added P10 AES/GCM code added some files containing
    CRYPTOGAMS perl-asm code which are near duplicates of the p8 files
    found in drivers/crypto/vmx.
    
    In particular the newly added files produce functions with identical
    names to the existing code.
    
    When the kernel is built with CONFIG_CRYPTO_AES_GCM_P10=y and
    CONFIG_CRYPTO_DEV_VMX_ENCRYPT=y that leads to link errors, eg:
    
      ld: drivers/crypto/vmx/aesp8-ppc.o: in function `aes_p8_set_encrypt_key':
      (.text+0xa0): multiple definition of `aes_p8_set_encrypt_key'; arch/powerpc/crypto/aesp8-ppc.o:(.text+0xa0): first defined here
      ...
      ld: drivers/crypto/vmx/ghashp8-ppc.o: in function `gcm_ghash_p8':
      (.text+0x140): multiple definition of `gcm_ghash_p8'; arch/powerpc/crypto/ghashp8-ppc.o:(.text+0x2e4): first defined here
    
    Fix it for now by renaming the newly added files and functions to use
    "p10" instead of "p8" in the names.
