6.17-stable review patch. If anyone has any objections, please let me know.
We have open regression reports about this, so I don't think we should backport it yet:

I've received a similar report for v6.17.3-rc1/ v6.17.3 (v6.17.2 was fine) on a Lenovo 82FG/ Ideapad 5-15ITL05 (i5-1135G7 and Xe graphics), failing to (UEFI-) boot already within the initramfs (Debian/ unstable, initramfs-tools).
Backing out (only) the changes to drivers/pci/msi/irqdomain.c and include/linux/msi.h from patch-6.17.3 fixes the regression again.

This is caused by the vmd driver, as vmd driver rely on the assumption that pci domain template does not set irq_startup()/irq_shutdown.
I think this may needs the following patch: https://lore.kernel.org/all/20251014014607.612586-1-inochiama@gmail.com
