freebsd kernel with SKQ

/usr/src/sys/i386/isa/clock.c: o Garrett's statclock changes. o Wire xxxintr, not Vclk. o Wire using register_intr(), not setidt(). /usr/src/sys/i386/isa/icu.s: o Garrett's statclock changes. o Removed unused variable high_imask. o Fake int 8 for rtc as well as int 0 for clk. Required for kernel profiling with statclock, harmless otherwise. /usr/src/sys/i386/isa/isa.c: o Allow isdp->id_irq and other things in *isdp to be changed by probes. Changing interrupts later requires direct calls to register_intr() and unregister_intr() and more care. ALLOW_CONFLICT_* is brought over from 1.1.5, except ALLOW_CONFLICT_IRQ is not supported. IRQ conflict checking is delayed until after probing so that drivers can change the IRQ to a free one; real conflicts require more cooperation between drivers to handle. o Too many details to list. o This file requires splitting and a lot more work. /usr/src/sys/i386/isa/isa_device.h: o Declare more things more completely. /usr/src/sys/i386/isa/sio.c: o Prepare to register interrupt handlers as fast. /usr/src/sys/i386/isa/vector.s: o Generate entry code for 16 fast interrupt handlers and 16 normal interrupt handlers. Changed some constants to variables: # $unit is now intr_unit[intr]. Type is int. Someday it should be a cookie suitable for the handler (e.g., a struct com_s for sio). # $handler is now intr_handler[intr]. # intrcnt_actv[id_num] is now *intr_countp[intr]. The indirection is required to get a contiguous range of counters for vmstat and so that the drivers depend more in the driver than on the interrupt number (drivers could take turns using an interrupt and the counts would remain correct). There is a separate counter for each device and for each stray interrupt. In 1.1.5, stray interrupt 7 clobbers the count for device 7 or something worse if there is no device 7 :-(. # mask is now intr_mask[intr] (was already indirect). o Entry points are now _XintrI and _XfastintrI (I = intr = 0-15), not _VdevU (U = unit). o Removed BUILD_VECTORS stuff. There's a trace of it left for the string table for vmstat but config now generates the string in one piece because nothing more is required. o Removed old handling of stray interrupts and older comments about it.
