Andrew Boie 999e706dba mvic: fix how local interrupts are programmed
MVIC has only one local interrupt: the timer IRQ. What IRQ line
to use is not fixed, instead it is programmed into the LVTTIMER
register. This is unlike LOAPIC which has a fixed IRQ for the timer
and instead the *vector* to use for it is programmed into LVTTIMER.

We don't want _loapic_int_vec_set() to do anything as the relationship
between IRQ lines and vectors is fixed and we do not want to be
programming vector numbers into bits 0-3 of LVTTIMER.

The IRQ line to use for timer interrupts is programmed into LVTTIMER
when the MVIC is initialized.

Andrew Boie a664aae335 x86: reduce static IRQ stub size
All of these stubs at the end pop the stack and tell the LOAPIC
that we are at EOI. Put this in common code which falls through to
_IntExit(). Saves 8 bytes per static IRQ stub. There is also small
constant savings in the common code for dynamic IRQs.

Andrew Boie 88808f1247 quark_se: apic: work around EOI forwarding issue
Quark SE Lakemont core has a hardware bug where the LOAPIC does
not properly notify the IOAPIC to clear the IRR bit for level-
triggered interrupts.

This patch introduces a workaround where the vector ID of the
in-service interrupt is manually written to the IOAPIC_EOI
register, resulting in the bit being cleared.

Unfortunately, in the context where EOI happens it's very difficult
to identify which IRQ line is being serviced, so this is done
unconditionally for all interrupts vectors whether they are registered
in the IOAPIC RTE table or not.

Andrew Boie c25d6c5d63 loapic: handle spurious interrupts
A special situation may occur when a processor raises its task
priority to be greater than or equal to the level of the
interrupt for which the processor INTR signal is currently
being asserted. If at the time the INTA cycle is issued, the
interrupt that was to be dispensed has become masked (programmed
by software), the local APIC will deliver a spurious-interrupt
vector. Dispensing the spurious-interrupt vector does not affect
the ISR, so the handler for this vector should return without an EOI.

vector as described in the x86 CPU manual volume 3 section 10.9.
Make this its own config option defaulting to 32.

MVIC doesn't have a spurious interrupt vector, and due to the
fixed IRQ-to-vector mapping for this controller, continue
to use the last available entry.
