2007-10-11[MIPS] Sibyte: Replace SB1 cachecode with standard R4000 class cache code.Ralf Baechle
It may not be perfect yet but the SB1 code is badly borken and has horrible performance issues. Downside: This seriously breaks support for pass 1 parts of the BCM1250 where indexed cacheops don't work quite reliable but I seem to be the last one on the planet with a pass 1 part anyway.

Note that the BCM4710 does not support the wait instruction, this is not a mistake in the code. It originally comes from the OpenWrt patches.

2007-07-29Remove fs.h from mm.hAlexey Dobriyan
Remove fs.h from mm.h. For this, 1) Uninline vma_wants_writenotify(). It's pretty huge anyway. 2) Add back fs.h or less bloated headers (err.h) to files that need it. As result, on x86_64 allyesconfig, fs.h dependencies cut down from 3929 files rebuilt down to 3444 (-12.3%).
