This implements the simultaneous read of the isochronous cycle timer and
the system clock (in usecs). This allows to express the exact receive
time of an ISO packet as a system time with microsecond accuracy.

The counterpart patch for libraw1394 can be found at
http://thread.gmane.org/gmane.linux.kernel.firewire.devel/8934
Patch update (Stefan R.): Disable preemption and local interrupts.
Prevent integer overflow. Add paranoid error checks and kerneldoc to
hpsb_read_cycle_timer. Move it to other ieee1394_core high-level API
functions. Change comments. Adjust whitespace. Rename struct
_raw1394_cycle_timer.

The Lubbock platform uses both a PXA25x and a SA1111 at the same time.
Both chips have the same "Serial Audio Controller" registers although
the SA1111 one is never expected to be used in preference to the PXA25x
one. So let's disable the SA1111 defines whenever compilation is for a
PXA architecture and make the PXA defines always defined.
This removes a bunch of "already defined" warnings as well since the
current hack to prevent them depended on include ordering which wasn't
always right.
While at it, clean up the SA1111 defines allowing to get rid of the
__CCREG() macro.

In copy_siginfo_from_user32:
Use compat_uptr_t. Use compat_ptr().
In copy_siginfo_to_user32:
Use compat_int_t. Use ptr_to_compat().
The sigevent_t structure has a 64-bit si_ptr field
that when copied to a 32-bit si_ptr will copy the wrong
word. For the compat copy use the si_int field instead.

show_stack() was calling kzalloc() to allocate a struct pt_regs.
This meant that *really* early stack dumps would cause a null pointer
dereference. x86_64 allocates its pt_regs on the stack, so do the same.

Al Viro did this for x86-64 and reduced the number of dependencies on
sched.h significantly. We had a couple of files which were relying on
uaccess.h pulling in sched.h, so they need explicit dependencies added.
