This not only makes sense, it fixes DEBUG_PAGEALLOC together with
the new page zeroing, since we must map the page before we zero it.

As per Chris Wright.

For some reason the asm versions of atomic_dec_and_test and friends were
masked by inefficient and big macros. With it I spare up to 8k in the text
size of my coldfire linux and 5k on my cpu32 version.

A number of small updates to the ColdFire serial driver:

. support the SNEHA platform
. set the default baud rate for console different on the FEITH boards
. add support for the 527x ColdFire CPU's
. schedule_timeout() should not add in current jiffies value
. optimize way that receive error characters are processed
. fix condition where receiver interrupts could be left disabled after flush

Remove duplicated definition of THREAD_SIZE, it is defined in page.h.
Also modify asm constraints to explicilty let gas know that the input
arg is a constant in the current_thread_info() function.

The 527[01] ColdFire devices and the 527[45] devices have a very similar

Patch from Nicolas Pitre

Those defines are incomplete and not using them by
instead using the explicit flags makes for clearer code.

Signed-off-by: Nicolas Pitre

Essentially, this set of changes:
1. makes the register usage in head.S more sane
2. makes way for passing the location of the tagged list via "r2"
   (as the booting document suggests)

This brings the latency back to previous levels, and in
fact seems to drive it a bit lower.

There were a few variants on the list trying to work out what the valid
ranges to verify for write are but they sort of missed the point, if you
can load new firmware you can have fun anyway.
