Subject[PATCH v5 0/5] powerpc8xx: Further optimisation of TLB handling
This patchset provides a further optimisation of TLB handling in the 8xx.
Changes are:
- Not saving registers like CR when not needed
- Adding support to any TASK_SIZE

Only the last patch of the set is changed compared to v4

Christophe Leroy (5):
powerpc/8xx: macro for handling CPU15 errata
powerpc/8xx: Handle CR out of exception PROLOG/EPILOG
powerpc/8xx: dont save CR in SCRATCH registers
powerpc/8xx: Use SPRG2 instead of DAR for saving r3
powerpc/8xx: Add support for TASK_SIZE greater than 0x80000000
