Subject: [x86] [MCE] Updated 32bit merge for tip x86 mce2 branch
Hi,
This patchkit finishes the 32bit/64bit merge of the MCE code
that is in the x86 tip x86/mce2 branch.
This is all based on earlier patches I posted to linux-kernel several
times for merging 32bit/64bit
I first fixed some bugs in mce2 (make it compile and some other problems)
and then forward ported my old 32bit merge patches on top of it.
The 32bit merge patches port all the bug workarounds in the 32bit
code to the 64bit code and then enable the 64bit mce code
for 32bit too.
This is currently a CONFIG option for easier forward-backwards
testing, but that CONFIG will go away after one major release.
I also added the basic MCE inject infrastructure because I needed
that for testing.
The branch needs a rebase for HEAD and a merge for some bug fixes in linus'
tree, but that's easily done (I didn't do it so far)
Also my fixes for mce2 could be collapsed into the earlier changes
there (I didn't do this to make it clear what I changed), feel free to do that.
I also reverted one patch where the patch author agreed it should
be reverted.
I addressed all feedback I got on earlier versions of this I believe.
Could this tree please be merged into tip and enabled for linux-next?
I will post the other pending MCE improvements on top then once
that is in.
That's all 2.6.31 material.
Thanks,
-Andi
