: Log:
: Change the x86 interrupt code to suspend/resume interrupt controllers
: (PICs) rather than interrupt sources. This allows interrupt controllers
: with no interrupt pics (such as the 8259As when APIC is in use) to
: participate in suspend/resume.
: - Always register the 8259A PICs even if we don't use any of their pins.
: - Explicitly reset the 8259As on resume on amd64 if 'device atpic' isn't
: included.
: - Add a "dummy" PIC for the local APIC on the BSP to reset the local APIC
: on resume. This gets suspend/resume working with APIC on UP systems.
: SMP still needs more work to bring the APs back to life.
:
: The MFC after is tentative.
This likely obsoletes the pmtimer device.
