This is a followup to my patches that fixed this all over the tree quite some
time ago. This one went unnoticed for some reason.
TLB handling for CRIS contains local_irq_disable() after local_save_flags().
Turn this into local_irq_save().

something-bility is spelled as something-blity
so a grep for 'blit' would find these lines
this is so trivial that I didn't split it by subsystem / copy
additional maintainers - all changes are to comments
The only purpose is to get fewer false positives when grepping

This patch adds m68knommu support for getting the kernel command line
arguments from uboot, including the passing of an initrd image from uboot.
We use this on a 5270/5271 based board, and have used it on the 5271evb
development board. It is based on a patch found in the linux-2.6-denx
git tree, although that tree seems to have had lots of other changes
since which are not in the main Linus kernel. I believe this will work
on all coldfires, although other m68knommu might be missing the _init_sp
stuff in head.S as far as I can tell. I only have the coldfire to
test on.

Now that associative cache writes are no longer needed by the SH-4/SH-4A
cache flush code, associative write support can be explicitly disabled
for all SH-4A parts. This makes any associative write throw an exception,
as this behaviour can not be assumed to exist on future parts.

When flushing/invalidating the icache/dcache via the memory-mapped IC/OC
address arrays, the associative bit should only be used in conjunction with
virtual addresses. However, we currently flush cache lines based on physical
address, so stop using the associative bit.
It is a better strategy to use non-associative writes (and physical tags) for
flushing the caches anyway, because flushing by virtual address (as with the
A-bit set) requires a valid TLB entry for that virtual address. If one does not
exist in the TLB no exception is generated and the flush is silently ignored.
This is also future-proofing for SH-4A parts which are gradually phasing out
associative writes to the cache array due to the aforementioned case of certain
flushes silently turning in to nops.

A number of small optimisations to FPU handling, in particular:
- move the task USEDFPU flag from the thread_info flags field (which
is accessed asynchronously to the thread) to a new status field,
which is only accessed by the thread itself. This allows locking to
be removed in most cases, or can be reduced to a preempt_lock().
This mimics the i386 behaviour.
- move the modification of regs->sr and thread_info->status flags out
of save_fpu() to __unlazy_fpu(). This gives the compiler a better
chance to optimise things, as well as making save_fpu() symmetrical
with restore_fpu() and init_fpu().
- implement prepare_to_copy(), so that when creating a thread, we can
unlazy the FPU prior to copying the thread data structures.
Also make sure that the FPU is disabled while in the kernel, in
particular while booting, and for newly created kernel threads,
In a very artificial benchmark, the execution time for 2500000
context switches was reduced from 50 to 45 seconds.

The previous implementation of clear_user_highpage and copy_user_highpage
checked to see if there was a D-cache aliasing issue between the user
and kernel mappings of a page, but if there was they always did a
flush with writeback on the dirtied kernel alias.
However as we now have the ability to map a page into kernel space
with the same cache colour as the user mapping, there is no need to
write back this data.
Currently we also invalidate the kernel alias as a precaution, however
I'm not sure if this is actually required.
Also correct the definition of FIX_CMAP_END so that the mappings created
by kmap_coherent() are actually at the correct colour.
