in the buffer cache.
When the Dynamic Buffer Cache has been introduced bread_cluster()
became the replacement of cluster_read(). However this function
did not consider the B_CACHE flag of the first buffer of a cluster
like its predecessor did.
This improves a lot read operations on MSDOSFS while reducing the
number of DMA operations.

link_maxhdr is best explained as the space reserved before an ip
packet payload for link headers, the most common of which is ethernet.
16 was a good choice when the only traffic we really did was ip
over ethernet, but now there are commonly used transports that are
bigger, specifically 802.11 traffic and vlan/vlan encapsulations,
that justify bumping it up.
i chose 64 because it would also allow enough space for encapsulations
like etherip or gif.
this reduces the size of the smallest packet that can fit into an
mbuf before more storage needs to be suffixed, but because most
traffic is either full sized (ie, already bigger than a single mbuf)
or tiny packets (think tcp ACKS, keystrokes over ssh, or dns requests)
the impact is negligible.

if a physical interface receives a multicast/broadcast packet and
has carp interfaces on it, that packet needs to be copied for
reception by each of those carp interfaces.
previously it was using m_copym2, but that doesn't respect the
alignment of the source packet. this meant the ip header in the
copies were aligned incorrectly for the network stack, which breaks
strict alignment archs.
m_dup_pkt lets carp specify that the payload needs an ETHER_ALIGN
adjustment, so the ip header inside will be aligned correctly.
reported and tested by anthony eden who hit this on armv7
i reproduced the problem on sparc64 and verified the fix on amd64

Use 115200 the default speed for buffer sizing in ttymalloc(). A lot
of devices call ttymalloc(0) so this affects quite a few of them.
Increases the buffer size for 9600 < baud <= 115200 from 1k to 4k.
Make ppp use the lo/hi watermarks from the tty layer which are
adjusted according to speed + buffer size. The previous fixed values
of 100 and 400 were way too small
Make pty call ttymalloc() with baud == 1000000, which is the common
value used in the tree for "fast".

This will allow to pledge vmd(8)'s vmm and vm processes, so that VMs

It will remain disabled for now (in userland) to not get into the way

basically only the ioctls that Linux allows on the so-called "render nodes".
For now, it also allows DRM_IOCTL_GET_MAGIC and DRM_IOCTL_GEM_OPEN, as we
don't implement prime/dma-buf yet in OpenBSD. That still leaves a big gaping
hole, so they will be removed as soon as we can.

behaviour of the chromium GPU process, with some further suggestions by

oflags & 3 == 3 case. Therefore this depends on vn_open() blocking the
operation later. Probably this meant the ni_pledge request would be too
high, causing transient operation failure, rather than transient operation
passage). Instead of initializing based on the oflags value use the
result of FFLAGS(). I should have done this from the start.

to tputchar() and could crash the kernel. Better use cnwrite() in
sendsyslog2() for writing to console. It takes a struct uio which
does the copyin() automatically. In addition cnwrite() outputs to
the real console or to a redirected one, whichever is appropriate.
One drawback is that the syslog priority cannot be stripped off
easily.
