c2ddc52f2d The cache flush routines now take a CPU context parameter. This is going

079b83cafa Extend the matching routine to take a function pointer, so that additional 
(arbitrary) matching can be done.
Add match function and patch for Cycle 5 IP (Sparc 5 clone).

cc079cff49 release the kernel lock if trace_enter fails. 
XXX[1]: We need to fix all platforms that do this.
XXX[2]: x86 does not check for MPSAFE syscalls before grabbing the lock.

6f945ab887 Allow a `fast trap' handler installation to be undone if an interrupt level

argument to intr_establish().

c822c6bd84 Finish the switch to the softintr(9) framework. 
To make this work, we now have to use separate handler lists for hardware

an `interrupt handled' status.

Thanks to Matt Fredette for providing an initial set of patches on port-sparc.

38b8c5689a Use 0x07ffffff for LOADADDR mask. This still provides for 128MB (and 
given that PROM maps just 4 or 16 this is not going to be a bottle
neck).  Doesn't really affect normal kernels, need it for the changed
kernel base address (uncommitted) hack for broken javastation OFW.

1b719337bb Pass the `device class interrupt level' on to intr_establish() and use to 
raise the ipl in the interrupt handlers to the appropriate level. This avoids
interrupt handler interference if one of the devices actually interrupts at
a lower hardware level than the maximum level assined to a device class.

Based on code from Art Grabowski in openbsd.
