Although this may not be an issue in practice, it would be more correct if the 64-bit version was used. Also, using the 64-bit version would make it easier to add support for 64-bit ubldr on MIPS.

SoCs and various chips (including, famously, their wifi chips.)
This is "just" (all 20,000 lines of it) code to enumerate the various
versions of busses inside these devices, including the PCI bridge and
the direct SIBA bridge found in MIPS chips.
It also includes shared code for some bus operations (suspend, resume, etc);
EEPROM/SROM/etc parsing and other things that are shared between chips.
Eventually this'll replace the code that bwi/bwn uses for the internal
bus, as well as some apparently upcoming mips74k broadcom SoC support
which uses bwn!
Thanks to Landon Fuller <landonf@landonf.org> for all this work!

The HDMI driver will attach a framebuffer device when a display is
connected. If the EDID can be read and contains a preferred mode, it
will be used. Otherwise the framebuffer will default to 800x600.
In addition, if the EDID contains a CEA-861 extension block and the
"basic audio" flag is set, audio playback at 48kHz 16-bit stereo is
enabled on the controller.

After calling the cap_init(3) function Casper will fork from it's original
process, using pdfork(2). Forking from a process has a lot of advantages:
1. We have the same cwd as the original process.
2. The same uid, gid and groups.
3. The same MAC labels.
4. The same descriptor table.
5. The same routing table.
6. The same umask.
7. The same cpuset(1).
From now services are also in form of libraries.
We also removed libcapsicum at all and converts existing program using Casper
to new architecture.

- The network controller verifies Rx TCP/UDP/SCTP checksums by default.
Communicate this to the stack when the packet is not marked as erroneous
to avoid redundant checksum calculation in kernel.
- It is not uncommon to get the mbuf with m_len that is less than
the minimal size for the IP, TCP, UDP, etc. when HW checsumming
is enabled. To avoid data corruption performed by the HW that is
intended to write IP and TCP/UDP/SCTP checksums to the data segment,
the mbuf needs to be pulled up by the required number of bytes.
- Make sure that one can modify the mbufs that require checsum calculation
rather than check for NULL mbuf on each transmission.

In the DIOCRSETADDRS ioctl() handler we allocate a table for struct pfr_addrs,
which is processed in pfr_set_addrs(). At the users request we also provide
feedback on the deleted addresses, by storing them after the new list
('bcopy(&ad, addr + size + i, sizeof(ad));' in pfr_set_addrs()).
This means we write outside the bounds of the buffer we've just allocated.
We need to look at pfrio_size2 instead (i.e. the size the user reserved for our
feedback). That'd allow a malicious user to specify a smaller pfrio_size2 than
pfrio_size though, in which case we'd still read outside of the allocated
buffer. Instead we allocate the largest of the two values.
