More or less an Alliance Semiconductors ProMotion AT24 with some PCI-SBus
glue and 4MB framebuffer. No acceleration yet, just enough wsdisplay/vcons
setup and DAC programming to be functional.
A concrete result is enabling unpatched libpthread to run on the
rumprun stacks (e.g. Xen and bare metal) with a non-NetBSD scheduler.
Those schedulers hook into the existing _lwp_frobnitz() NetBSD syscall
interfaces (well, "syscall" interfaces in that scenario ;)
More specifically about the change itself:
1) instead of calling _lwp_makecontext() followed by _lwp_create()
and passing the entry point in ucontext_t (MD) through the calls, roll
the calls into pthread__makelwp() and allow alternate implementations
for that MI interface.
2) allow compile-time overriding of __lwp_gettcb_fast() or
__lwp_getprivate_fast, which are inline and leak MD scheduler/thread
details into libpthread
Additionally, two small nits:
I) define LIB=pthread before including mk.conf so that it's possible
to test for LIB==pthread in mk.conf
II) make it possible to leave out pthread_cancelstub.c. This is required
by the current implementation of rumprun-posix (i.e. rumprun on
POSIX hosts) due to symbol collisions. It needs to be fixed properly
some day, but for now allows an almost-correct libpthread to run.
I am sure @justin will be happy to explain the details ;)

0001. Do not recognize paths, mail folders, and pipes in mail addresses
by default. That avoids a direct command injection with syntactically
valid email addresses starting with |.
Such addresses can be specified both on the command line, the mail
headers (with -t) or in address lines copied over from previous
while replying.
This was assigned CVE-2014-7844 for some versions of BSD mailx. It is
documented behavior for Heirloom mailx, and was mentioned in an old
technical report about BSD mailx (which does not usually make its way
into operating system installations). The patch switches off this
processing and updates the documentation.
Added expandaddr option to explicitly enable this behavior.
0002. When invoking sendmail, prevent option processing for email
address arguments. This prevents changing e.g. the Postfix
configuration file in unexpected ways. This behavior was documented for
BSD mailx (sort of), but not for Heirloom mailx. We did not assign a
CVE to this because it is more of a missing feature, and code invoking
mailx needs adjustment in the caller as well.
Fixed.
0003. Make wordexp support mandatory. (No functional change.)
Fixed (replaced explicit shell pipe implementation).
0004. Prevent command execution in the expand function, which is IMHO
unexpected. (Not really required with patch 1, and there is still
information disclosure/DoS potential if this expansion occurs.) This is
a historic vulnerability already fixed in the Debian package,
retroactively assigned CVE-2004-2771:
Fixed (as part of the pipe replacement with wordexp).
to unwind the stack. Add a temporary workaround where we simply don't
allow the thread to exit (a kernel thread exit is a relatively uncommon
event in a rump kernel anyway).
- Allow signals while reading the user crontab file; doing "crontab -"
does not let you abort otherwise, and doing ^Z, kill %1 leaves turds
in /var/cron/tabs
Define the default, empty "build_kernel" target, so that old source trees,
whose sys/conf/Makefile.kern.inc don't have "build_kernel" .USE target, can
be built.
(When "build_kernel" is defined, the target is overriden, as far as
sys/conf/Makefile.kern.inc is included later than the "netbsd: ..." definition
in sys/arch/*/conf/Makefile.*.)
This should address PR bin/49389.
if_attach initializes an ifnet object and registers it to the system
(e.g., ifnet_list), however, if_attach doesn't complete the
initialization and the rest of it will be done by if_alloc_sadl
that is normally directly called by device drivers or called via
functions like ether_ifattach. So there is a race between
if_attach and if_alloc_sadl (A half-baked ifnet object may be
accessed, for example, via ioctl between them).
The aim of this fix is to register an initializing ifnet object
after completing its initializations. To this end, this fix
separates if_attach into an initialization part (if_initialize)
and a registration part (if_register) and call the latter after
if_alloc_sadl (ether_ifattach). So a typical usage of the two
new APIs is like this:
if_initialize(ifp); // was if_attach
ether_ifattach(ifp, enaddr);
if_register(ifp);
Nonetheless, changing every drivers to do so at once isn't
feasible. So we keep if_attach working as it used to be and
will change only some drivers that we need at this point.
Once we know the fix really works well, we'll change all
the others.
Some more information of the fix can be found here:

No objection on tech-kern and tech-net.
mappings of file objects. move vnode-specific details of mmap()ing a vnode
from uvm_mmap() to the new vnode-specific vn_mmap(). add new uvm_mmap_dev()
and uvm_mmap_anon() convenience functions for mapping character devices
and anonymous memory, and replace all other calls to uvm_mmap() with those.
use the new fileop in drm2 so that libdrm can use mmap() to map things
like on other platforms (instead of the ioctl that we have used so far).
