cap_t() appears to be defined under ifdef __KERNEL__. Which makes
sense since it takes a struct kernel_cap_t :) I don't have the
source code you're compiling, and don't know what would be the "right"
way to fix it, but to get your code to compile I'd just put a
#define cap(x) (x).cap
at the top of the .c files needing it.
