dcbz, dcbf, dcbi, dcbst and icbi do not set DAR when they
cause a DTLB Error. Dectect this by tagging DAR with 0x00f0
at every exception exit that modifies DAR.
Test for DAR=0x00f0 in DataTLBError and bail
to handle_page_fault().

This is an assembler version to fixup DAR not being set

uses selfmodifing code(default), the other uses

Update the TLB asm to make proper use of _PAGE_DIRY and _PAGE_ACCESSED.
Pros:
- I/D TLB Miss never needs to write to the linux pte.
- _PAGE_ACCESSED is only set on TLB Error fixing accounting
- _PAGE_DIRTY is mapped to 0x100, the changed bit, and is set directly
when a page has been made dir
OK, here is the next try att fixing the MPC8xx MMU

DataTLBError currently does:
if ((err & 0x0200) == 0)
DSI();
This won't handle a store with no valid translation.
Change this to
if ((err & 0x4800) != 0)
DSI();
that is, branch to DSI if either !permission or
!translation.

This patch updates percpu related symbols in powerpc such that percpu
symbols are unique and don't clash with local symbols. This serves
two purposes of decreasing the possibility of global percpu symbol
collision and allowing dropping per_cpu__ prefix from percpu symbols.
