Hi Linus,
I appreciate that it's extremely late in the cycle, but we've uncovered
a nasty bug in the arm64 KVM code which allows a badly behaved 32-bit
guest to bring down the host. The fix is simple (it's what I believe we
call a brown paper bag bug) and I don't think it makes sense to sit on
When injecting a fault into a misbehaving 32bit guest, it seems
rather idiotic to also inject a 64bit fault that is only going
to corrupt the guest state. This leads to a situation where we
perform an illegal exception return at EL2 causing the host
to crash instead of killing the guest.
Just fix

There is a downside of halt_poll_ns since poll is still happen for idle
VCPU which can waste cpu usage. This patchset add the ability to adjust
halt_poll_ns dynamically, grows halt_poll_ns if an interrupt arrives and
shrinks halt_poll_ns when idle VCPU is detected.
There are two new kernel
