Dear David Jander,
In message <[email protected]> you wrote:
Complete workaround for DTLB errata in e300c2/c3/c4 processors.
Due to the bug, the hardware-implemented LRU algorythm always goes
to way
1 of the TLB. This fix implements the proposed software workaround
in
form of a LRW table for chosing the TLB-way.

What is the actual status of this patch?
Patchwork (http://patchwork.ozlabs.org/patch/24502/) says it's
"superseded" - but by what?
I can't see such code in mainline - what happened to it?
I can see the code in mainline ... but only in the -data- TLB miss
handler, not the instruction one...
Kumar ? Shouldn't we have the workaround in both ?
The errata was only for the d-side. The patch is in the mainline
kernel.
