Peter Grehan a48c333805 Allow the PIC's IMR register to be read before ICW initialisation. ... As of git submit e179f6914152eca9, the Linux kernel does a simple probe of the PIC by writing a pattern to the IMR and then reading it back, prior to the init sequence of ICW words. The bhyve PIC emulation wasn't allowing the IMR to be read until the ICW sequence was complete. This limitation isn't required so relax the test. With this change, Linux kernels 3.15-rc2 and later won't hang on boot when calibrating the local APIC. Reviewed by: tychon MFC after: 3 days		2014-09-27 01:15:24 +00:00
