Subject: [SPARC64]: Disable IRQ forwarding.
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=41832a08feca695158e15a6e58c26b224a7bfae2;p=GitHub%2FLineageOS%2Fandroid_kernel_samsung_universal7580.git

[SPARC64]: Disable IRQ forwarding.

There is some race whereby IRQs get stuck, the IRQ status
is pending but no processor actually handles the IRQ vector
and thus the interrupt.

This is a temporary workaround.
