_PAGE_COHERENT is now always set in _PAGE_RAM resp. PAGE_KERNEL.
Thus it has to be masked out, if the BAT mapping should be non
cacheable or CPU_FTR_NEED_COHERENT is not set.
This will work on normal SMP setups because we force-set
CPU_FTR_NEED_COHERENT as part of CPU_FTR_COMMON on SMP.

In the VIO bus code the wrappers for dma alloc_coherent and free_coherent
calls are rounding to IOMMU_PAGE_SIZE. Taking a look at the underlying
calls, the actual mapping is promoted to PAGE_SIZE. Changing the
rounding in these two functions fixes under-reporting the entitlement
used by the system. Without this change, the system could run out of
entitlement before it believes it has and incur mapping failures at the
firmware level.
Also in the VIO bus code, the wrapper for dma map_sg is not exiting in
an error path where it should. Rather than fall through to code for the
success case, this patch adds the return that is needed in the error path.

Fix cache flushing for the 527x ColdFire processors

Along with this add support for flushing the 523x cache, which uses
the same format as the 527x ColdFire's, and was missing flush support.

Part of the code that did not make sense to me got removed by Greg.
This is part two:
The first compare is to check whether the interrupts are disabled or not.
Depending on the result we exectute the RESTORE_ALL macro is not only
restoring the stack but also returning to caller.
The test for pending softirq has been removed because it is allready done
in irq_exit().
Since system_call() is allso using the SAVE_ALL macro and returning via
ret_from_exception label I see no reason why we could not do this here
as well. This is also handy because if we return from the timer interrupt
and we need to resched than we check for this :)
