- Fixed arm mcount/arm_return_addr so they aren't under OABI_COMPAT ifdefs .
- adds a new NR_syscalls macro, converts the old one into __NR_syscalls for
calculating the table padding .
- removes old semaphore __MUTEX_INITIALIZER()
- depends blocker on X86
- updates clockfw_lock to a raw_spinlock_t
Looks like arm hasn't been compiled in a while .. Needs an updated for
generic irqs too. There's still some struct semaphore usage , shouldn't
they be either compat_semaphore or mutex types now ?
