- Use 32-bit function alignment as GCC does when using UltraSPARC I or
higher optimizations.
- Don't waste delay slots when possible.
Unfortunately, this still doesn't make libcompiler_rt a viable replacement
for libgcc on sparc64 though as once installed instead, buildworld times
increase by nearly 60% (which isn't related to these assembler functions).
used, when the code should actually protect the tested
variable with a mutex. Since the tsleep()s had a 10sec
timeout, the race would have only delayed the allocation
of a new clientid for a client. The sleeps will also
rarely occur, since having a callback in progress when
a client acquires a new clientid, is unlikely.
in practice, since having a callback in progress when
a fresh clientid is being acquired by a client is unlikely.

depending upon the bootloader initialising it.
The aim is to eventually support a full switch set and reinitialisation
rather than relying on a consistent bootloader setup.
Remove the port flood config from arswitch.c, it's not yet used and
it's totally incorrect.
Whilst I'm here, also add in a comment describing why the full switch
reset is disabled.

which carries fictitous managed pages. In particular, the consumers of
the new object type can remove all mappings of the device page with
pmap_remove_all().
The range of physical addresses used for fake page allocation shall be
registered with vm_phys_fictitious_reg_range() interface to allow the
PHYS_TO_VM_PAGE() to work in pmap.
Most likely, only i386 and amd64 pmaps can handle fictitious managed
pages right now.

for allocation of fictitious pages, for which PHYS_TO_VM_PAGE()
returns proper fictitious vm_page_t. The range should be de-registered
after consumer stopped using it.
De-inline the PHYS_TO_VM_PAGE() since it now carries code to iterate
over registered ranges.
A hash container might be developed instead of range registration
interface, and fake pages could be put automatically into the hash,
were PHYS_TO_VM_PAGE() could look them up later. This should be
considered before the MFC of the commit is done.

AFAICT, this makes FreeBSD the first operating system besides Nut/OS

* Add the etherswitch/rtl8366rb drivers;
* "fix" the USB GPIO configuration so USB actually works.
