Here is a respin of previously posted patches that remove pinned
DTR per-cpu TLB requirement. Instead we use DTC to map that
translation.
With these two patches, we measured substantial performance gain
on a database benchmark, in the vicinity of 1.6%. I've also done
extensive performance measurement on two other industry standard
benchmarks (cpu, java), and have found to have small gain on those
workloads.
Detail description in the follow on patches.

Christoph's variable kernel page size support patch reminds me
this 10 month old patch:
http://marc.theaimsgroup.com/?l=linux-ia64&m\x114074826111970&w=2
I strongly believe it is stable enough for 2.6.19. Reposted here
for mainline consideration.
