Hi all, We've seen a regression on several lts branches(at least 5.10,5.15,6.1) causing boot issues on cuttlefish/crossvm android emulation on arm64.
The offending patch is: PCI: Use preserve_config in place of pci_flags
It looks like this patch was added to stable by AUTOSEL but without the other 3 patches in the series: https://lore.kernel.org/all/20240508174138.3630283-1-vidyas@nvidia.com/
Applying the missing patches resolves the issue but they do not apply cleanly.
Can we revert this patch on the lts branches?

Sure, can you please send the revert with all of this information so we get it correct and you get proper credit for finding/fixing it?
thanks,

Thanks Greg, whats the best way to do that? Do you need a patch for each lts branch affected or just one based on stable?

One for each branch please, as the git ids for the commit is different on each one, right?
Look at commit acddb8762014 ("Revert "rcu-tasks: Fix access non-existent percpu rtpcp variable in rcu_tasks_need_gpcb()"") for an idea of how to write the header.
thanks,

Thanks that's what I assumed but wasn't sure if there was some script that did some magic.
Sent those to stable now, let me know if there are any issues.
Looks good, I'll get to them next week...
