No need to wait, we can do that now:
#regzbot fix: x86/cpu/amd: Make the NODEID_MSR union actually work
But ideally Thomas would add Link: or Closes: tag to the patch description (e.g.
Closes: https://lore.kernel.org/all/20240322175210.124416-1-laura.nao@collabora.com/
) just like Linus asked him to do a while ago already[1], as then this would not be necessary at all. ;) (SCNR)
Ciao, Thorsten (wearing his 'the Linux kernel's regression tracker' hat)
