I tried using:

$  gcc -E -D__GENKSYMS__ -DCONFIG_MODVERSIONS -DEXPORT_SYMTAB
crypto/api.c -I/tmp/linux-3.0.2/include
-I/tmp/linux-3.0.2/arch/x86/include -include
include/generated/autoconf.h  | ./scripts/genksyms/genksyms

and it returned the checksums like:

  __crc_crypto_alg_list = 0x86fb488e ;
  __crc_crypto_alg_sem = 0xb7865a4f ;
  __crc_crypto_chain = 0x2f947450 ;
  __crc_crypto_mod_get = 0x67cda209 ;
  ...

But, in Module.symvers there is only crypto_mod_get and its checksum
is 0x3286637f which is different from the one listed above.

This generated the api.symtypes file.

Sorry, I didn't understand. Can you elaborate on what needs to be done here?

Thanks for your reply,
