Merge tag 'irq_urgent_for_v5.11_rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip 

Pull irq fixes from Borislav Petkov:

 - Fix a kernel panic in mips-cpu due to invalid irq domain hierarchy.

 - Fix to not lose IPIs on bcm2836.

 - Fix for a bogus marking of ITS devices as shared due to unitialized
   stack variable.

 - Clear a phantom interrupt on qcom-pdc to unblock suspend.

 - Small cleanups, warning and build fixes.
