to built-ins, so eventually we will have one version of these files.
Special adjustments for the kernel to cope: machine/stdarg.h -> sys/stdarg.h
and machine/ansi.h needs to have a _BSD_VA_LIST_ for syslog* prototypes.
okay millert@, drahn@, miod@.

now call the poll backend. With this change we implement greater
poll(2) functionality instead of emulating it via the select backend.
Adapted from NetBSD and including some changes from FreeBSD.
Tested by many, deraadt@ OK

as sparc* do not use Xsun-compatible event interface anymore, and alpha only
used this for Xtga which we do not ship anymore.
Discussed long ago with matthieu@

the decode to be wrong.
|
|
- good start are fully decoding LDQF(A)/STQF(A)
|
|
|
|
T_ILLINST handler fetches instruction and decodes it. If it's stqf, ldqf,
stqfa, or ldqfa call emulation instead of SIGILL directly.
Note: this still SIGILL's in the end, the emulation isn't done yet.

associate a name with each interrupt handler. This is not visible
outside the kernel (yet).

pointers, and adapt creator to the fb api.

and eventually share some drivers.
This also brings us screen unblanking upon entering ddb, which can be really
useful at times...

rescinded 22 July 1999. Proofed by myself and Theo.

has arguments but no clobbers, then everything is clobbered. The in-tree
gcc also likes to insert redundant "sra"s. These changes help gcc generate
somewhat better code for the spl*() functions. This change shrank my GENERIC
kernel by 27136 bytes.
ok jason@

assym.h can do that for us.
mdw@ henric@ ok

everything (so gcc doesn't assume everything is clobbered).

trying to use the interrupt pin (or is it that the PCI
function?) as the interrupt vector, this computes the vector
from the PCI bus, slot, and pin. This will only change mappings
on psycho-based machines (*not* sabre, i.e., IIi/e) and only for
those vectors reported as nonsense INRs (INO 0-3).
This should fix the mapping of non-bridge expansion cards on U60
and E450, and other psycho boxen. U30 seems to do its own
thing.

them available via sysctl (doc update in a bit); ok millert.

both a "next" pointer for a singly-linked list and as an in-use flag.
This obviously does not work all that well. This change adds a separate
ih_busy flag to mark the handler as in-use, leaving ih_pending for use by
the list code.
Testing by *many* (thanks).

on faster systems under heavy network load. This replaces some of the
unreadable iommu functions with something a little less dense and a lot
less crash prone.
The bus_dma function pointer/cookie handling was broken. Change them
to work like the stacked bus_space drivers (where "work" is the key
word).
Tested my many (thanks).

Reduce the size of a GENERIC kernel by ~190k
Remove the nasty pointer/bus_space_handle_t casts
Adds debug bus_space code including the ability to trace
bus operations (it actually works now).
The following rules are now followed (and verfified by the debug
code):
1. A "bus_space_handle_t" may only be used with the
"bus_space_tag_t" that created it.
2. Only "bus_space_map()" may create "bus_space_handle_t"s.
3. A "bus_space_handle_t" may not be modified after it has
been created (other than being destroyed by "bus_space_unmap()").
Thanks to help from mcbride, marc, jason, drahn, to anyone that might
have slipped my mind at the moment.
ok jason@, deraadt@

store function pointers in the pci_chipset_tag_t (ie. fix an ugly hack
I did during the hackathon last year).

The only OSes I've seen that use SIZE_T_MAX are 4.4BSD-derived whereas
SYSV things seem to use SIZE_MAX. It is also consistent with SSIZE_MAX
(which we already have). deraadt@ OK

usage of cdev_decl() in the driver code is more tricky since i have
kqueue mods here and there and will fix that on that way through.

We will never have a.out kernels.
We will never have 32-bit kernels.
We will never have sun4c, sun4 and sun4m support in the sparc64 kernels.
We don't need support old netbsd libc.
The cpu will never be identified as some of the sun4c and sun4m types.
We don't need the gazillion of fields in cpuinfo that the sparc port uses.
Just generally remove dead code.
This is just a first step in making this meess readable.
