Subject: [ARM] Remove needless linux/ptrace.h includes

Lots of places in arch/arm were needlessly including linux/ptrace.h,
resumably because we used to pass a struct pt_regs to interrupt
handlers.  Now that we don't, all these ptrace.h includes are
redundant.

Subject: [ARM] sa1100: use mutexes rather than semaphores

Use a mutex in the sa1100 clock support rather than a semaphore.
Remove the unused "module" field.
