Pull the initial preempt_count value into a single

Maintainers for: alpha, ia64 and m68k, please have a look,
your arch code is funny.
The header magic is a bit odd, but similar to the KERNEL_DS
one, CPP waits with expanding these macros until the
INIT_THREAD_INFO macro itself is expanded, which is in
arch/*/kernel/init_task.c where we've already included
sched.h so we're good.

Implement the TIF_NOTIFY_RESUME thread flag, making it call do_notify_resume()
which then clears it. This will be made use of later by tracehooks in the
new-style ptrace implementation
Also discard TIF_IRET as that's not used by FRV.
