Unlike most other PHYs there is no easy way to know which media
type the PHY supports on Marvell PHYs. MIIF_HAVEFIBER flags is now
passed via bus-specific instance variable of a device. While I'm
here add 88E1112 specific work around to set SIGDET polarity low.

Who knew that "svn export" was an actual command, or that I would have
vfs_export.c stuck in my mind deep enough to type "export" instead of
"commit"?

are currently two problems with the use of 1GB page mappings by the direct
map. First, at least one device driver uses pmap_extract() rather than
DMAP_TO_PHYS() to translate a direct map address to a physical address.
Unfortunately, neither pmap_extract() nor pmap_kextract() yet support 1GB
page mappings. Second, pmap_bootstrap() needs to interrogate the MTRRs to
ensure that a 1GB page mapping doesn't span two MTRRs of different types.

- F_READAHEAD: specify the amount for sequential access. The amount is
specified in bytes and is rounded up to nearest block size.
- F_RDAHEAD: Darwin compatible version that use 128KB as the sequential
access size.
A third argument of zero disables the read-ahead behavior.
Please note that the read-ahead amount is also constrainted by sysctl
variable, vfs.read_max, which may need to be raised in order to better
utilize this feature.
Thanks Igor Sysoev for proposing the feature and submitting the original
version, and kib@ for his valuable comments.

contained only SLIST_HEAD as its member, thus sizeof(struct klist) would
equal to sizeof(struct klist *), so this change makes the code more
correct in terms of semantics, but should be a no-op to compiler at this
time.

- clean up USB detach logic. There seems to be some problems detaching multiple
USB HUBs connected in series from the root.
- after this patch the rule is:
1) Always use device_detach() on the USB HUB first.
2) Never just device_delete_child() on the USB HUB, because that function
will traverse to all the device leaves and free them first, and then the USB
stack will free the devices twice which doesn't work very well.
- make sure the did DMA delay gets set after the timeout has elapsed to make
logic more clear. There is no functional difference.

fstab: /etc/fstab:0: No such file or directory
and from dump(8) when setfsent(3) fails due to /etc/fstab not existing:
DUMP: Can't open /etc/fstab for dump table information: No such...
This makes daily and security periodic runs somewhat cleaner in jails
which lack /etc/fstab files.

The most important test is the mapping fixed at address 0 depending on the
new sysctl.
Things will be updated and possibly converted to m4/.t style once the
details about the kernel patch will be shaken out.

umount, and mdconfig.
- Remove trap handler again after we have unconfigured the memory
device etc. Before we could end up running the trap handler if a
later stage failed, which was a bit confusing and not really useful.

Right now if applications want to use the mouse on the command line,
they use sysmouse(4) and install a signal handler in the kernel to
deliver signals when mouse events arrive. This conflicts with my plan to
change to TERM=xterm, so implement proper VT200-style mouse input.
Because mouse input is now streamed through the TTY, it means you can
now SSH to another system on the console and use the mouse there as
well. The disadvantage of the VT200 mouse protocol, is that it doesn't
seem to generate events when moving the cursor. Only when pressing and
releasing mouse buttons.
There are different protocols as well, but this one seems to be most
commonly supported.

This is done to make it harder to exploit kernel NULL pointer security
vulnerabilities. While this of course does not fix vulnerabilities,
it does mitigate their impact.
Note that this may break some applications, most likely emulators or
similar, which for one reason or another require mapping memory at
zero.
This restriction can be disabled with the security.bsd.mmap_zero
sysctl variable.
