- Require sun_family to be set to AF_UNIX (also in unp_connect())
- Ensure internal sockaddr_un's always have their length set to
sizeof(struct sockaddr_un) regardless of the user specified length,
implicitly extending with NUL characters as necessary.
- Normalize sun_path to never contain a non-NUL character after a
NUL character.
Lack of NUL termination on truncated sockaddrs issue pointed out by
Michael Kerrisk on the Austin Group mailing list.

without virtual aliasing, or for pages which are not currently mapped
cached. 1+% speed increase on sgi IP27 and loongson kernels.
Tested on LS2F, R4400, R5000, R12000 and R16000.

- correctly gather version information. When reading device registers is a two
step process (write address, read data), it is a very bad idea to call a
wrapper around these two operations (to read register B) between the two
operations inline (to read register A). Unless you want to know the version
information for your garbage latches, that is. Now Indy 8-bit devices
no longer get reported as 24-bit devices, and Indy 24-bit devices no longer
get reported as 8-bit devices. (not that it mattered much anyway)
- define and use symbolic constants when parsing the video mode settings to
figure out the display resolution. This code still itches, but much less now.

that it can now tell ID-less framebuffers apart correctly. Therefore, we can
use direct configuration instead of ugly games. Frame buffer drivers match
routines now only need to check for the fake ID they receive.
Tested on various newport and grtwo setups (including multihead configurations)

- replace masking with large `power of two minus one' constants with a pair of
shifts, this is shorter code and does not require the at register.
- merge R5000 and RM52xx setup, as the configuration register layout is the same
on both processors.
- In Mips5k_IOSyncDCache(), delay building the call frame until we know we
will not perform a leaf call. Replace leaf calls with jumps to the
appropriate routines.
Tested on R5000, RM5271 and RM7000.

.S code when masking the upper bits, instead of hardcoding them. Makes code
easier to understand (and also I might have a need to reduce PFN width on
some particular CPU models in the future).
No change in generated code.

the size (internalized ones can be larger on some architectures) for
fitting into the socket. Avoid getting confused by sb_hiwat as well.
This fixes a variety of issues where sendmsg() would fail to deliver
a fd set or fail to wait; even leading to file leakage.
Worked on this with claudio for about a week...

to a trap)' dance before invoking trapsignal(), which will mess with the pc
too. My bug initially, can't believe I never noticed; fixed first in NetBSD.
This makes libsqlite3 build.

to pass both the virtual and physical addresses of the page to clean to
SyncDCachePage, which is the only routine using `Index' operations on the data
cache, which might be virtually indexed at some levels but physically indexed
at others. On the other hand, it does not make any sense to pass a physical
address to routines using `Hit' operations (and they were discarding them
anyway).
In addition to making things cleaner, this fixes sporadic userland misbehaviour
(read: SIGSGEV) on RM7000 O2 systems.

8:8:8, and use the fast putchar code unconditionally: it turns out it
expects the background color as 4:8:4. This fixes the `character background
is too green and too light' effect that caused this code path to only be used
for black background, and the slower code for the rest.

(That means the misplaced optimization is back in.) It broke mips and

bus-specific attachment; impactreg.h and impactvar.h move from sgi/xbow/ to
sgi/dev/.
Teach the generic impact code how to code with pre-ImpactSR boards, which have
a slightly different register layout (information obtained from Peter Fuerst's
Linux IP28 patches).
Add an impact@gio attachment (unfortunately untested, no Impact GIO boards
here). All Indigo 2 graphics options should be supported now (assuming the
Extreme/Ultra will actually work with grtwo(4) out of the box).
Tested not to disturb operation on IP30.
** ATTENTION! If you are building IP27 or IP30 kernels, be sure to rm impact.d
** before building a new kernel.

identifier is actually the first word of the boards' shared ram, and might
have a legit value. Be sure to probe for the signature register before
deciding we have found a GIO board.
While there, if we have a glass console attached, don't bother probing it
again at autoconf time, since we have already identified it.

and can return completely bogus values; writing these values back to the
register can have unexpected and hilarious side effects, such as disabling the
frame buffer.
Workaround this `feature' by reading the register in a loop until we read
twice the same value, and the value looks legit; then cache this value in a
global variable and handle the register from now on, as a write-only register.

thread information.
Add a KERN_PROC_SHOW_THREADS flag that has to be set in order to get the
thread info and make it off by default. This creates backwards compatibility
for applications that relied on a given size/number of items to be returned.
Modify ps(1) and top(1) accordingly.

The optimization goes through great lengths to use less optimized code

(NG1, XL, XGE) frame buffer.
Adapted from NetBSD; newport extended to support underline and fonts wider than
8 pixels, such as the default 12x22 Gallant font. Framebuffer depth computation
seems to be wrong on Indy models, to be investigated later (but doesn't prevent
text console from working).

false positives.
Do not look for framebuffers past GIO EXP1, there shouldn't be anything there.
Add the console code machinery to attach a glass console on IP22, when the
appropriate drivers will exist.
On multihead systems, get console framebuffer address (well, sort of) from a
completely undocumented interface (knowledge taken from Linux, confirmed to
work on a dual-head Indigo 2 here).
While there, get frame buffer names from ARCBios whenever possible, to be used
in dmesg eventually.
