Subject: [PATCH v2 0/3] Optimisation on 8xx prior to hugepage implementation

This serie is a prologue of hugepage implementation on the 8xx.
It some how optimises the DTLBMiss handler while allowing at the
same time to hook the hugepage handling that will be introduced in
a subsequent patch serie.

v1 of those patches was part of a serie identified
"powerpc/8xx: implementation of huge pages"

Christophe Leroy (3):
  powerpc/8xx: use r3 to scratch CR in ITLBmiss
  powerpc/8xx: Move additional DTLBMiss handlers out of exception area
  powerpc/8xx: make user addr DTLB miss the short path
