A quick look at the change history and two tests are suggesting that the 
right one already is in cc.

commit

f7fa7ae x86/irq: Avoid memory allocation in __assign_irq_vector()

fails while

af87bae x86/htirq: Use new irqdomain interfaces to allocate/free IRQ

works. Inbetween almost all changes are from Jiang Liu.

Haven't bisected it up to now but might do it later.
