Konstantin Belousov 9a5d210cb4 It seems that at least some KVM versions advertise support for EIO
suppression but the version of the IOAPIC reported is 0x11 and neither
IOAPIC EOIR nor the Linux trick of temporal reprogramming of the pin
to edge-trigger mode to issue EOI work.

Disable eoi suppression if KVM is detected.  The mode can still be
forced with the tunable.
