NFS may have some influence here, but I doubt it is the primary cause
for these variations. The n

Hello Joakim,
I tried your 4 patches on a MPC855M based system:
-bash-3.2# cat /proc/cpuinfo
processor : 0
cpu : 8xx
clock : 66.00MHz
revision: 0.0 (pvr 0050 )
bogomips: 8.25
timebase: 4125000
platform: TQM8xx
model : T
This set of tries to optimize the TLB code on 8xx even
more. If they work, it should be a noticable performance
boost.
I would be very happy if you could test them for me.
- v2:

them with my SOB.
Scott, can you "bless" these pa
