[PATCH] MIPS updates 

 o General updates of MIPS to 2.6.10-rc2
 o Remove the Baget platform due to lack of maintenance over several years.
   Some of the drivers remain and will be removed in a separate patch.
 o Remove the HP Laserjet platform.  No user reports ever and no patches from
   the original submitters made this port a neat hack - and a directory full
   of clutter.
 o SMP support for the PMC-Sierra.

this problem, but it will currently (2/95) cause BFD to allocate
