Additionally, x86 maintainers: is there a particular reason this (or any functionally equivalent patch) isn't upstream yet? As indicated before, I had not been able to find any discussion, and hence I see no reason why this is a patch we effectively carry privately in our distro branches (and likely other distros do so too).
The patch was merged 6 weeks ago and is now upstream:
71c208dd54ab: x86/xen: Zero MSR_IA32_SPEC_CTRL before suspend
I'm sorry, but no, this isn't the patch I was inquiring about. Instead I'm wondering of the disposition of the patch disabling IBRS around a CPU going idle.
Got any specific link or subject line for that submission?
Sure, as written in the original response to Jürgen's patch: https://patchwork.kernel.org/patch/10153843/
Argh, indeed you did!
In any case, this submission from Tim Chen:
[PATCH v3 0/5] IBRS patch series
Contained a glaring bug in patch #2 which Thomas pointed out, and AFAICS the series was never resubmitted to lkml so it got lost.
In any case thanks for the reminder!
Thanks,
Ingo
