fixes some namespace pollution in general and breakage of modules that
aren't in the sys tree in particular (<machine/ipl.h> includes further
headers that aren't installed under /usr/include).
Reimplemented SPLASSERT() so that it is more machine independent and
less bloated and doesn't require the <machine/ipl.h> include spam.
In particular, don't assume that `cpl' can be printed using %08x
format. The alpha arch doesn't even have `cpl'. SPLASSERT() was
harmless on alphas because it isn't actually used.
run out of KVM through a mmap()/fork() bomb that allocates hundreds
of thousands of vm_map_entry structures.
Add panic to make null-pointer dereference crash a little more verbose.
Add a new sysctl, vm.max_proc_mmap, which specifies the maximum number
of mmap()'d spaces (discrete vm_map_entry's in the process). The value
defaults to around 9000 for a 128MB machine. The test is scaled for the
number of processes sharing a vmspace (aka linux threads). Setting
the value to 0 disables the feature.

1) Fix a bug in the int15 function 87 emulation where we only copied half
of what the BIOS asked for. This caused the Mylex RAID adapter to go
haywire and start trashing memory when you tried to boot from it.
2) Don't use interrupt 19 to reboot. Instead, set the reboot flag to a warm
boot and jump to the BIOS's reboot handler. int 19 doesn't clear memory
or restore the interrupt vector table, and thus really isn't safe. For
example, when booting off of PXE, the PXE BIOS eats up a chunk of memory
for its internal data and structures. Since we rebooted via int 19,
using the 'reboot' command in the loader resulted in that memory not
being reclaimed by the BIOS. Thus, after a few PXE boots, the system
was out of lower memory.
3) Catch any int 19 calls made by a BTX client or a user pressing
Ctrl-Alt-Delete and shutdown BTX and reboot the machine cleanly. This
fixes Ctrl-Alt-Delete in the loader and in boot2 instead of presenting
the user with a BTX fault.

This basically resurrects revision 1.106 from old /sys/i386/isa/isa.c.

1) Non-AST4 multiport cards were broken by bypassing the code that changes
`idev' to the multiport master device.
2) AST4 multiport cards apparently were broken by inverting the test for
the master device having an irq.
3) Error handling for nonexistent master devices was broken by removing a
check for a null pointer.
4) `int' error codes returned by bus_get_resource() were assigned directly
to the boolean variable com->no_irq. Probably harmless, since the
boolean is implemented as a u_char.

(potentially very bogus) switchtime from our own CPU to calculate
resource usage on another CPU.
This should remove some if not all calcru() related warnings on SMP.

Andrew's problems with SCSI on some alphas- do not call isp_update
directly to update parameters- just mark them as being ready to
update for the next command- the system would just hang on a READ
CAPACITY for a drive. Really annoying because it wouldn't even timeout
(and it has a timeout) so either the SET PARAMETERS call was nuking
things or the f/w was really dropping the ball.

- Remove all the code intended to deal with experimental
C1010 revisions. This code got useless due to commercial
chip revisions having been fixed.
Fixes:
- Rewrite/rework the WSR condition handling.
Previous drivers snooped on the BUS through the SBDL IO
register and this has been discovered to trigger a spurious
SCSI parity error when WSR had been set by chip and cleared
by SCRIPTS prior to reading SBDL bit [0...7].
On the other hand, the C1010 does not use the SWIDE register
when synchronous data transfers are taking place and
requires a CHMOV (1) WHEN DATA_IN to be performed in order
to move to memory the residual byte when WSR is set and
the residual byte is useful data.
BTW, the new WSR handling by the driver is simpler.
- No longer attempt to read from SCRIPTS the SBDL register.
This is intended to avoid to be victimized again by any other
issue regarding the handling of this register by 8xx chips.
Miscellaneous:
- The driver is now able to handle the WSR + IGN RESIDUE
condition at the end of a DATA IN I/O without need of a
programmed interrupt. It is a minor? optimization.
- A few other minor cosmetic changes.
This driver version fixes notably a permanent SCSI parity
error condition at boot that can be triggerred due to recent
changes in cam_xpt.c between 1.79 and 1.80.
Changes in CAM/XPT are fine, but the new handling of the full
INQUIRY may trigger the driver problem when a target returned
an odd value in the `additionnal length' field of the INQUIRY
response.
The diff against previous driver version is large, but it
consists approximatively in:
- 350 lignes removed and not compiled in previous drivers
(They addressed experimental C1010 revisions)
- 250 lignes added or changed, half being comments or empty
lines.
So, in fact, the real changes are about 120 lines of source.
About 80 lines address SCRIPTS changes and about 40 lines
address C code changes.
