The grows-up and grows-down cases had all the same issues, but
differered in the details. Additionlly, historical evolution of
the tests had caused the result to be pretty unreadable with some
rather long and complex conditionals.

Fix it all up in a more readable helper function.

This also adds the missing RLIMIT_MEMLOCK test.

We use a non-atomic kmap() to clear the page, which cannot be
used from atomic contexts.

It doesn't do the virtual cache synchronization that clear_user_highpage()
does.

Pointed out by Hugh Dickins.

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.
