30# Bignum configuration (BIGNUM_CFG):
31#   PSR_MUL:
32#       There is a processor-specific implementation bignum multiply functions
33#   HWCAP:
34#       There are multiple implementations of bignum functions, and the
35#	appropriate one must be chosen at run time, based on testing
36#	hardware capabilites.
37#   MMX_MANAGE:
38#	Multimedia registers must be saved and restored.
39#	Normally MMX_MANAGE iff _KERNEL, but for testing purposes,
40#	MMX_MANAGE can be defined in userland.
