      m68knommu: set NO_DMA · e0212e72
      Adrian Bunk authored 
      m68knommu does not set the Kconfig NO_DMA variable, but also does
not provide the required functions, resulting in the following
build error triggered by commit a40c24a1
(net: Add SKB DMA mapping helper functions.):

      m68knommu: fix cache flushing for the 527x ColdFire processors · a1a9bcb5

      Fix cache flushing for the 527x ColdFire processors
Its CACR register format is slightly different.

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.

      m68knommu: fix ColdFire 5272 serial baud rates in mcf.c · 26a4bc66
      John Adamson authored 
      I noticed (the hard way) that the mcf.c driver doesn't support the fractional precision register on the MCF5272.  This makes the console dicey at 115200 baud and a system clock of 66.0 MHz.  On the other hand, if your hardware is running at 66.666 MHz, it probably isn't a problem.

      m68knommu: use one exist from execption · c7bcd0df
      Sebastian Siewior authored 
      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 :)

      Introduced by 8adb711f ("debugfs:
introduce stub for debugfs_create_size_t() when DEBUG_FS=n") and due to
a simple missing "static inline".
