SVN rev 187149 on 2009-01-13 15:41:58Z by raj
Rework BookE pmap towards multi-core support.
o Eliminate tlb0[] (a s/w copy of TLB0)
- The table contents cannot be maintained reliably in multiple MMU
environments, where asynchronous events (invalidations from other cores)
can change our local TLB0 contents underneath.
- Simplify and optimize TLB flushing: system wide invalidations are
performed using tlbivax instruction (propagates to other cores), for
local MMU invalidations a new optimized routine (assembly) is introduced.
o Improve and simplify TID allocation and management.
- Let each core keep track of its TID allocations.
- Simplify TID recycling, eliminate dead code.
- Drop the now unused powerpc/booke/support.S file.
o Improve page tables management logic.
o Simplify TLB1 manipulation routines.
o Other improvements and polishing.
