I was unable to find any of the arches having subarch-specific NR_syscalls macros, so generic NR_syscalls is used. SH's syscall_get_arch seems to only have the 32-bit subarch implementation. I'm not sure if this is expected. This series has not been tested; I have not built all the cross compilers necessary to build test, let alone run the kernel or benchmark the performance, so help on making sure the bitmap cache works as expected would be appreciated. The series applies on top of Kees's for-next/seccomp branch.
