This is a resend.. this latest respin is updated to apply on top of Mikeys
slb_mmu_size change.
(earlier Updates made per comments from Olof and Ben and Paul).
This version adds padding around the ESID and VSID fields, and the LLP bits
are display
.cpu_user_features = COMMON_USER_POWER7,
> + .cpu_user_features = COMMON_USER2_POWER7,
^ Oops here, I think.Please consider applying this on top.
Untested, but seems obvious.
Fix a typo in setting COMMON_USER2_POWER7 bits to .cpu_user_features2

This version adds padding around the ESID and VSID fields, and the LLP bits

I'm seeing some funky behavior on power5/power6 partitions with this

"/sbin/halt".
Anybody else seeing this, or is it time for me to call an exorcist for
my boxes?
