controllers combine multiple TX requests into single one if there
is room in TX buffer of controller. Updating TX packet counter at
the end of TX completion resulted in incorrect TX packet counter as
axe(4) thought it sent 1 packet. There is no easy way to know how
many combined TX were completed in the callback.
Because this change updates TX packet counter before actual
transmission, it may not be ideal one. But I believe it's better
than showing fake 8kpps under high TX load. With this change, TX
shows 221kpps on Linksus USB200M.
'inline' to 'static inline'. Otherwise, a C99 compiler (such as clang)
will output an undefined symbol for those functions in the resulting
object file. (Even gcc will do this, when you use "-std=c99".)
This should fix the "undefined reference to `set4pixels'" errors that
some people were seeing during ports building, when their world was
compiled with clang.

addresses that is greater than a superpage in size but not a multiple of
the superpage size, then vm_map_find() is not always expanding the kernel
pmap to support the last few small pages being allocated. These failures
are not commonplace, so this was first noticed by someone porting FreeBSD
to a new architecture. Previously, we grew the kernel page table in
vm_map_findspace() when we found the first available virtual address.
This works most of the time because we always grow the kernel pmap or page
table by an amount that is a multiple of the superpage size. Now, instead,
we defer the call to pmap_growkernel() until we are committed to a range
of virtual addresses in vm_map_insert(). In general, there is another
reason to prefer calling pmap_growkernel() in vm_map_insert(). It makes
it possible for someone to do the equivalent of an mmap(MAP_FIXED) on the
kernel map.

PLT support, I forgot to update the PLT icache synchronization code to cover
the extended PLT instead of just the basic PLT.

suspicious about 'l' and '1' being confused in numeric constants.
The fear being that some old fart programmer might still think that
he is using a Remmington Noiseless as input terminal device.
An easy way to placate this fear is to use capital 'L' or to put
the 'u' in unsigned constants in front of the 'l'.

Unlike actual MTRR, this only controls the mapping attributes for
subsequent mmap() of /dev/mem. Nonetheless, the support is sufficiently
MTRR-like that Xorg can use it, which translates into an enormous increase
in graphics performance on PowerPC.

trap frame when trap initiated kdb entry, incorrectly calculated the
value of %rsp for trapped thread.
According to Intel(R) 64 and IA-32 Architectures Software Developer's Manual
Volume 3A: System Programming Guide, Part 1, rev. 035, 6.14.2 64-Bit Mode
Stack Frame, "64-bit mode ... pushes SS:RSP unconditionally, rather than
only on a CPL change."
Even assuming the conditional push of the %ss:%rsp, the calculation
was still wrong because sizeof(tf_ss) + sizeof(tf_rsp) == 16 on amd64.
Always use the tf_rsp from trap frame. The change supposedly fixes
stepping when using kgdb backend for kdb.

interface is also backwards compatible to USB2.0 and USB1.0 and will
evntually replace the OHCI/UHCI and EHCI drivers.
There will be follow-up commits during the coming week to link the
driver into the default kernel build and add missing USB3.0
functionality in the USB core. Currently only the driver files are

- Update message ring handler registration, use the real device station id
for registering interrupts.
- rge/nlge: update for the new message ring registration code.
- rge/nlge: use 2 message ring stations for incoming packets, this will
allow more messages to be queued.

The split is almost trivial, as the code is almost perfectly
non-intertwined. The only adjustment needed was to move the UMA
zone allocation out of vfs_mountroot() [in vfs_mountroot.c] and
into vfs_mount.c, where it had to be done as a SYSINIT [see
vfs_mount_init()].

supporting isolation in mii_mediachg() and just ignore it rather than
panicing, which should sufficient given that a) things are likely to
just work anyway if one doesn't plug in more than one port at a time and
b) refusing to attach in this case just leaves us in a unknown but most
likely also not exactly correct configuration (besides several drivers

setting this flag for no real reason).

using sc->mii_anegticks instead of hardcoded values etc.
