How did you send it?
Ugh, you bounced it? No wonder I didn't do anything with it at all, it looked exactly like a "this is being committed to the TIP tree" type message.
How was I supposed to know what to do with it?
Please be more specific next time, read: https://www.kernel.org/doc/html/latest/process/stable-kernel-rules.html for how to do this properly.
A simple "please commit git id XXXXX to the X.X tree" is all that is needed.
I'll definitely do this in the future.
For my info which "X.X" tree is significant? In this case I'm guessing that it would be the version where the breakage occurred? Or is it some other specific major or minor version change?
The end goal is for the distros to pull them in and they usually monitor certain stable trees for new commits for their own releases. But they generally don't share with us those details.
Wait, in looking closer at this:

Ok, that commit showed up in 4.16: $ git describe --contains bd47a85acd727e27b7283daff557865ad04c59f6 v4.16~2^2
But the commit this fixes:

x86/platform/UV: Fix critical UV MMR address error
A critical error was found testing the fixed UV4 HUB in that an MMR address was found to be incorrect. This causes the virtual address space for accessing the MMIOH1 region to be allocated with the incorrect size.
Fixes: 673aa20c55a1 ("x86/platform/UV: Update uv_mmrs.h to prepare for UV4A fixes")
Is in 4.16-rc1: $ git describe --contains 673aa20c55a1 v4.16-rc1~174^2~9
And is not backported to any other stable tree that I see: $ fr 673aa20c55a1 4.16 $ alias fr alias fr='~/linux/scripts/fix_in_what_release'
So what exactly am I supposed to do with this commit? What do you want to see done with it?
totally confused,
greg k-h
I am too. The earlier "breakage" was committed on Jan 8th and has been pulled into earlier releases by the distros. It was the initial patch for enabling UV4A HUB systems, so it was not a fix to software, but an update in response to fixed hardware (to allow NVDIMMS and Icelake CPUs).
Should this have been pushed to "stable" as well?
