management bits, and doesn't support older controllers, but that shouldn't

the value fusubail in the pcb_onfault field of the wrong process if a
profiling timer interrupt happened to occur inside cpu_switch() at a
point where curproc had been updated to point to the new process but
curpcb still pointed to the old one. trap() would then fail to ignore
any page fault in fuswintr/suswintr and the system would lock up.
This bug only affected systems with kern_clock.c 1.72 or newer, as
earlier versions only call addupc_intr from interrupts that occur in
user mode. Fixed by assigning to curproc->p_addr->u_pcb.pcb_onfault
instead of curpcb->pcb_onfault, as the former is what trap() checks.
npxprobe1(), set npxdna_func to new npxdna_empty(). This function just

deal with shortages of the VM maps where the backing pages are mapped
(usually kmem_map). Try to deal with this:
* Group all information about the backend allocator for a pool in a
separate structure. The pool references this structure, rather than
the individual fields.
* Change the pool_init() API accordingly, and adjust all callers.
* Link all pools using the same backend allocator on a list.
* The backend allocator is responsible for waiting for physical memory
to become available, but will still fail if it cannot callocate KVA
space for the pages. If this happens, carefully drain all pools using
the same backend allocator, so that some KVA space can be freed.
* Change pool_reclaim() to indicate if it actually succeeded in freeing
some pages, and use that information to make draining easier and more
efficient.
* Get rid of PR_URGENT. There was only one use of it, and it could be
dealt with by the caller.

of removing the duplicate variables, make sure that any duplicate

While we're here, enable RAIDframe (and RAID_AUTOCONFIG) by default for
architectures that I'm comfortable can deal with it being on by default.
Also: bump the number of 'raid' devices from 4 to 8, since 4 seems to
be insufficient in practise.
Raising math exception from fpu_save causes machine reboots.
Also, this fwait would cause incorrect results, as pending exceptions
are to be handled later after fxrstor.
configuration of devices logically attached to the ISA bus:
* Change the isa_attach_args to have arrays of io, mem, irq, drq
resources.
* Add a "pnpnames" and a linked list of "pnpcompatnames" to the
isa_attach_args. If either of these members are non-NULL,
direct configuration of the bus is being performed. Add an
ISA_DIRECT_CONFIG() macro to test for this.
* Drivers are not allowed to modify the isa_attach_args unless
direct configuration is not being performed and the probe fucntion
is returning success.
* Adapt device drivers -- currently, all driver probe routines return
"no match" if ISA_DIRECT_CONFIG() evaluates to true.

- I added bsd.obj.mk and made it work with objdirs.
- I added an entry point to the linker to fix a warning.
- I made the backup of biostramp.inc silent.
- I added missing clean targets.
This needs to be tested further.
Any problems reported by testers have been fixed, and massive
