-Subject: [PATCH] Revert "MIPS: smp-mt: Use CPU interrupt controller IPI IRQ
- domain support"
-
-The problem is that the Lantiq IRQ controller gets registered first and
-it directly handles the MIPS native SW1/2 and HW0 - HW5 IRQs. It looks
-like this controller already registers IRQ 0 - 7 and the generic driver
-only gets the following IRQs starting later.
-
-The upstream discussion can be found at https://www.linux-mips.org/archives/linux-mips/2017-05/msg00059.html
-
-This reverts kernel commit 1eed40043579 ("MIPS: smp-mt: Use CPU interrupt
-controller IPI IRQ domain support").
