[git pull] m68knommu arch updates

[Greg Ungerer]

Hi Linus,

(I would normally send this from my gerg@xxxxxxxxxxxx email account,
but the server and routers for that have been under water recently :-(
Not sure when I will be able to get that back working again).

Can you please pull the m68knommu git tree, for-linus branch.

  git://git.kernel.org/pub/scm/linux/kernel/git/gerg/m68knommu.git 
for-linus

The most significant changes are:

1. using separate user and supervisor stack pointers on ColdFire
   parts that support it
2. reworking the CPU cache support, it now supports all forms of
   instruction and data cache on various ColdFire family members

Quite a few other cleanups and some random fixes in there too. The 548x
support has been made more generic and supports the 547x family as well.
A bit of dead code removal as well.

Thanks
Greg
