This is required by the generic loader code in newer versions of Mesa
even when we aren't building any nouveau drivers.
The way these headers are used on Linux is with a kernel version
and a libdrm version which are largely identical with the *_drm.h
headers always installed by libdrm when libdrm is built with autoconf.
In OpenBSD we have a single version of the _drm.h headers that
are shared by the kernel and userspace and have our own simple
Makefile for the libdrm build.

Move all legacy MAP_FOO values behind #ifndef _KERNEL and redefine
them to either be aliases for existing flags (e.g., MAP_COPY ->
MAP_PRIVATE) or 0.
Also, add MAP_OLDFOO defines (behind #ifndef _KERNEL) so the kernel
and kdump can remain compatible with current OpenBSD binaries.

(we need to make them signed to spot controller overruns), and fix format
strings accordingly.
While there, make sure every runtime printf is prefixed by either the complete
target information, if available, or at least the driver name with the
proper instance number - supported systems with > 1 wdsc are quite common.

an interface. Two other operations are performed when issuing a
SIOCDIFADDR{_IN6,} ioctl: call the address hook and the per-driver
ioctl function.
Since carp(4) relies on an address hook to recalculate its hash, make
sure to call this hook when IFXF_NOINET6 is set or when the rdomain is
changed.

width that isn't compatible with the alignment of the region:
OperationRegion (SATC, SystemMemory, 0xE008800A, 0x04)
Field (SATC, DWordAcc, NoLock, Preserve)
{
STCL, 16
}
DWordAcc means 4-byte access, but 0xE008800A is only 2-byte aligned.
Moreover, the region itself is 4 bytes long. From this I conclude
that 4-byte wide access to a 2-byte aligned address is really wanted
in cases like this.

is no link-local address assigned by default, which - by default, since
INET6 is in the GENERIC kernels - makes the machine and services on it
reachable. No such thing in IPv4 land.
since assigning an inet6 address manually or running rtsol(d) etc resets the
NOINET6 flag and causes the link-local to be assigned, this really is a noop
for all inet6 users with the exception of those ONLY using the default
link-local address. These needs to run "ifconfig <if> inet6 eui64" or put
the equivalent in hostname.if.

Modern compiler toolchains are capable of optimizing even across
translation unit boundaries, so simply moving the memory clearing into
a separate function is not guaranteed to clear memory.
To avoid this, we take advantage of ELF weak symbol semantics, and
insert a call to an empty, weakly named function. The semantics of
calling this function aren't determinable until load time, so the
compiler and linker need to keep the memset() call.
There are still ways a toolchain might defeat this trick (e.g.,
optimistically expecting the weak symbol to not be overloaded, and
only calling memset() if it is; promoting weak symbols to strong
symbols at link-time when emitting a static binary because they won't
be interposed; implementing load-time optimizations). But at least
for the foreseeable future, these seem unlikely.

DP 1.2 compatible displays may report a 5.4Gbps maximum bandwidth which
the driver will treat as an invalid value and use 1.62Gbps instead. Fix
this by capping to 2.7Gbps for sinks reporting a 5.4Gbps max bw.
Also add a warning for reserved values.

without an intervening STRIOCRESCWD, release the current values instead
of the saved values, so as to effectively emulate a STRIOCRESCWD.
While here, make sure the fdc->fd_[cr]dir members are updated before
vrele()ing their old values, so that they can't be caught as dangling refs.
