[PATCH 0/2] arm64: make it possible to enable threadirqs

Hi,

This patchset makes it possible to pass "threadirqs" on the CONFIG_CMDLINE to
make IRQs threaded.
This is safe to use now because all timer interrupts and the perf interrupt are
marked NO_THREAD.

NOTE: I had to add this patch [1] to be able to test this on a juno board.
Without this patch, I see unhandled IRQs in mainline. However, it is unclear
whether or not this will be the actual fix that appears in mainline [2].

Cheers,
Anders
