Use LOG2_ID_PAGE_SIZE again for the identity mapping in regions 6 & 7.
Make the default translation size the same as the PBVM page size to
avoid inserting overlapping translations in the TC. That generally is
very bad.
Kernel config for Wandboard.
Perform media change after setting IFF_DRV_RUNNING flag. Without it,
driver would ignore the first link state update if controller
already established a link.

prison_check_ip4() can take const arguments.
Cleanup in_ifscrub(), which is just an entry to in_scrubprefix().
in_ifadown() can be void.
Make getenv_*() functions and respectively TUNABLE_*_FETCH() macros not
allocate memory and so not require sleepable environment.  getenv() has
already used on-stack temporary storage, so just use it more rationally.
getenv_string() receives buffer as argument, so don't need another one.
Remove the dependency on procfs.

sh: Reorder union node to reduce its size on 64-bit platforms.
Add -f support to 'pkg bootstrap' and 'pkg add' to force installation
of pkg(8) even if already installed.

This is useful if you somehow messup pkg(8) and need to reinstall from
remote with it already being registered in the pkg(8) /var/db/pkg database.

Also add some sanity checks to 'pkg add'.

Add support for queued invalidation.

Right now, the semaphore write is scheduled after each batch, which is
not optimal and must be tuned.

small cleanup for building picobsd-head without CLANG.

Note that svn 257268 gnu/usr.bin/binutils/ld/Makefile
seems to break the "toolchain" target when building HEAD
on RELENG_9, so until this is solved you may want to

    svn update -r 257267 gnu/usr.bin/binutils/ld/Makefile

before building picobsd
Somehow fix LINT-NOIP.
OpenBSD 5.4 added.
TI sdhci driver improvements, mostly related to fdt data...

Use the published compatible strings (our own invention, "ti,mmchs" is
still accepted as well, for now).

Don't blindly turn on 8-bit bus mode, because even though the conroller
supports it, the board has to be wired appropriately as well.  Use the
published property (bus-width=<n>) and honor all the valid values (1,4,8).

The eMMC device on a Beaglebone Black is wired for 8-bit, update the dts.

The mmchs controller can inherently do both 1.8v and 3.0v on the first
device and 1.8v only on other devices, unless an external transceiver is
used.  Set the voltage automatically for the first device and honor
the published fdt property (ti,dualvolt) for other devices.

Thanks go to Ilya Bakulin for figuring out the voltage compatibility stuff.
The ability to do 8-bit implies 4-bit capability too.  Rearrange the cases
and add a fallthrough comment to make that happen.
Convert the random entropy harvesting code to use a const void * pointer
rather than just void *.

Then, as part of this, convert a couple of mbuf m->m_data accesses
to mtod(m, const void *).

update to the latest netmap snapshot.
This includes the following:
- use separate memory regions for VALE ports
- locking fixes
- some simplifications in the NIC-specific routines
- performance improvements for the VALE switch
- some new features in the pkt-gen test program
- documentation updates

There are small API changes that require programs to be recompiled
(NETMAP_API has been bumped so you will detect old binaries at runtime).

In particular:
- struct netmap_slot now is 16 bytes to support an extra pointer,
  which may save one data copy when using VALE ports or VMs;
- the struct netmap_if has two extra fields;
