Re: [RFC][PATCH v5] MPC5121 TLB errata workaround

[David Jander <david.jander@protonic.nl>]

In this patch, I placed the LRW table in SPRG6 like before, but Kumar's code 
seems a little more compact, so I decided to use that one and fix it ;-)

It's a pity we seem to have one register short in the handler, so we need to 
load SPRN_SRR1 twice :-(

Allthough the code-path now has 1 instruction less than my previous version 
most of the time (and 2 instructions more when way is not adjusted), 
benchmark results are barely affected by this:

1.- mplayer: Total time: 50.392s (50.316s previous patch)

2.- prboom timedemo: 20.1 fps (19.9 fps previous patch)

3.- memcpy speed: 179 MByte/s (180 Mbyte/s previous patch)

Conclusion: difference not measurable between v4 and v5.

Best regards,
