cd899aad76 Fix KBI breakage by r190520 which affects older linux.ko binaries:
1) Move the new field (brand_note) to the end of the Brandinfo structure.
2) Add a new flag BI_BRAND_NOTE that indicates that the brand_note pointer
   is valid.
3) Use the brand_note field if the flag BI_BRAND_NOTE is set and as old
   modules won't have the flag set, so the new field brand_note would be
   ignored.

beb3c3a9c5 Retire VM_PROT_READ_IS_EXEC. It was intended to be a micro-optimization,
but I see no benefit from it today.

VM_PROT_READ_IS_EXEC was only intended for use on processors that do not
distinguish between read and execute permission.  On an mmap(2) or
mprotect(2), it automatically added execute permission if the caller
specified permissions included read permission.  The hope was that this
would reduce the number of vm map entries needed to implement an address
space because there would be fewer neighboring vm map entries that differed
only in the presence or absence of VM_PROT_EXECUTE.  (See vm/vm_mmap.c
revision 1.56.)

Today, I don't see any real applications that benefit from
VM_PROT_READ_IS_EXEC.  In any case, vm map entries are now organized
as a self-adjusting binary search tree instead of an ordered list.  So,
the need for coalescing vm map entries is not as great as it once was.

8ba46ea415 Use Oxf0000000 instead of 0xff000000 to guess the physical address, relative
to the virtual one. I may had a reason at some point to use the later, but
can't remember which, and it can leads to issues.

339ccfb391 Hoist 802.11 encapsulation up into net80211:
o call ieee80211_encap in ieee80211_start so frames passed down to drivers
  are already encapsulated
o remove ieee80211_encap calls in drivers
o fixup wi so it recreates the 802.3 head it requires from the 802.11
  header contents
o move fast-frame aggregation from ath to net80211 (conditional on
  IEEE80211_SUPPORT_SUPERG):
  - aggregation is now done in ieee80211_start; it is enabled when the
    packets/sec exceeds ieee80211_ffppsmin (net.wlan.ffppsmin) and frames
    are held on a staging queue according to ieee80211_ffagemax
    (net.wlan.ffagemax) to wait for a frame to combine with
  - drivers must call back to age/flush the staging queue (ath does this
    on tx done, at swba, and on rx according to the state of the tx queues
    and/or the contents of the staging queue)
  - remove fast-frame-related data structures from ath
  - add ieee80211_ff_node_init and ieee80211_ff_node_cleanup to handle
    per-node fast-frames state (we reuse 11n tx ampdu state)
o change ieee80211_encap calling convention to include an explicit vap
  so frames coming through a WDS vap are recognized w/o setting M_WDS

With these changes any device able to tx/rx 3Kbyte+ frames can use fast-frames.

f060939f44 Small cleanup of memory resource allocation from Cambria branch:
o encode need for A4 bus space tag hackery according to the memory
  address; checking for "uart" breaks down with the GPS chip support
  which is also a uart but does not require the same hackery
o encode the correct memory window instead of carving up all of i/o
  space, potentially with a larger window than a device should have;
  this likely should be handled in the drivers by using a proper bus
  alloc call but since some drivers depend on the bus support to figure
  this out we cannot simply mod them
o add optional GPS and RS485 support (conditionally as the support
  isn't ready yet)

96c7367b9e The bounce zone sees its page number increased if multiple dma maps use it in
the same dma tag. However, it can happen multiple dma tags share the same
bounce zone too, so add a per-bounce zone map counter, and check it instead of
the dma tag map counter, to know if we have to alloc more pages.

047e5fdabc When bouncing pages, allow a new option to preserve the intra-page
offset.  This is needed for the ehci hardware buffer rings that assume
this behavior.

This is an interim solution, and a more general one is being worked
on.  This solution doesn't break anything that doesn't ask for it
directly.  The mbuf and uio variants with this flag likely don't work
and haven't been tested.

Universe builds with these changes.  I don't have a huge-memory
machine to test these changes with, but will be happy to work with
folks that do and hps if this changes turns out not to be sufficient.
