Move the ACPI PM timer emulation into vmm.ko. MFC r273706 Change the type of the first argument to the I/O emulation handlers to 'struct vm *'. MFC r273710 Add a comment explaining the intent behind the I/O reservation [0x72-0x77]. MFC r273744 Add foo_genassym.c files to DPSRCS so dependencies for them are generated. This ensures these objects are rebuilt to generate an updated header of assembly constants if needed. MFC r274045 If the start bit, PxCMD.ST, is cleared and nothing is in-flight then PxCI, PxSACT, PxCMD.CCS and PxCMD.CR should be 0. MFC r274076 Improve the ability to cancel an in-flight request by using an interrupt, via SIGCONT, to force the read or write system call to return prematurely. MFC r274330 To allow a request to be submitted from within the callback routine of a completing one increase the total by 1 but don't advertise it. MFC r274931 Change the lower bound for guest vmspace allocation to 0 instead of using the VM_MIN_ADDRESS constant. MFC r275817 For level triggered interrupts clear the PIC IRR bit when the interrupt pin is deasserted. MFC r275850 Fix 8259 IRQ priority resolver. MFC r275952 Various 8259 device model improvements. MFC r275965 Emulate writes to the IA32_MISC_ENABLE MSR.
