Fix various typos in comments, log messages and documentation.

Add missed "rasops1" attribute to smg(4) rasops'fied a year ago.

This fixes silent boot failure on VS3100 with smg(4) framebuffer console.
Should be pulled up to netbsd-10.

Add a support for gpx(4) color framebuffer found on VAXstation 3100.

Poted from OpenBSD/vax. Note smg(4) monochrome onboard framebuffer
driver is also changed attached only if gpx(4) is not installed
or flags 1 is specified in config files, as OpenBSD did.

Tested on my VAXstation 3100/m30 with and without 8bpp gpx(4).
Revied on port-vax@ and "Please go ahead!" from ragge@.

Worth to pullup to netbsd-10.

Retire compat_ibcs2, as discussed on tech-kern@. FreeBSD did the same
recently.

Add cpu_in_cksum.S.

USB for vax (similar to pmax; no/negligible impact on legacy):
* Add USB device files/majors.
* Make kernel configs with USB work.
* Provide a USB-enabled kernel config.

Make VAXstation 4000 TURBOchannel adaptor work.
PIO and IRQ tested on VS4000/60 and /96 with TC-USB (slhci) and PMAD-AA (le).
DMA is untested.
vax needs space to be mapped out, so memory space is pre-mapped for TC option
drivers not bus_space'ified yet, also providing custom bus_space methods for
this kludge.

Configury support for QVSS (from Charles Dickman)

Add audio support for VAXstation VLC, 60 and 90 machines. Originally rom
Blaz Antonic and ported from OpenBSD by Björn Johannesso. Tested on VLC
and 4000/60.

Welcome to 5.99.53! Merge rmind-uvmplock branch:

Welcome to 5.99.53! Merge rmind-uvmplock branch:

- Reorganize locking in UVM and provide extra serialisation for pmap(9).
New lock order: [vmpage-owner-lock] -> pmap-lock.

- Simplify locking in some pmap(9) modules by removing P->V locking.

- Use lock object on vmobjlock (and thus vnode_t::v_interlock) to share
the locks amongst UVM objects where necessary (tmpfs, layerfs, unionfs).

- Rewrite and optimise x86 TLB shootdown code, make it simpler and cleaner.
Add TLBSTATS option for x86 to collect statistics about TLB shootdowns.

- Unify /dev/mem et al in MI code and provide required locking (removes
kernel-lock on some ports). Also, avoid cache-aliasing issues.

Thanks to Andrew Doran and Joerg Sonnenberger, as their initial patches
formed the core changes of this branch.

A big bunch of bugfixes from Johnny Billquist. Highlights:
- Makes the VAX8600 work as expected (500kg of hardware :-)
- Fix a hard-tracked bug causing VAXen to hang at splhigh.

- add siginfo translation for all arithmetic faults and traps.
- skip the current instruction for all faults, to avoid infinite loops on
SIGFPE (from OpenBSD)

compile them only when the relevant config options are set.

- Provide a sendsig_sigcontext() implementation using the existing vax
signal code; it already does the correct thing.

Rototill the vax code. Switch to devicet/PRIV_ALLOC. Cleanup vax autoconf
code. Move to prototype definitions. staticfy, constify, avoid casting.
Use device_* accessors.

Revert last change.

them in the mi "files" file, and remove include statements from md files.

Since files.wscons et al. are included by ~all ports anyway, include
them in the mi "files" file, and remove include statements from md files.
These shouldn't pull in additional kernel code when not in use, so it
shouldn't do any harm except a risk of namespace collisions which
should be easy to fix.

Preliminatry TC support.

Refactor in_cksum/in4_cksum/in6_cksum implementations:
- All three functions are included in the kernel by default.
They call a backend function cpu_in_cksum after possibly
computing the checksum of the pseudo header.
- cpu_in_cksum is the core to implement the one-complement sum.
The default implementation is moderate fast on most platforms
and provides a 32bit accumulator with 16bit addends for L32 platforms
and a 64bit accumulator with 32bit addends for L64 platforms.
It handles edge cases like very large mbuf chains (could happen with
native IPv6 in the future) and provides a good base for new native
implementations.
- Modify i386 and amd64 assembly to use the new interface.

This disables the MD implementations on !x86 until the conversion is
done. For Alpha, the portable version is faster.

Partially adapt the VAX port to the newlock2 changes. These are untested
but they do at least compile.

Remove RASTERCONSOLE support from the pmax port.
