clock management code to honor these hardware limitations while choosing hz,
stathz and profhz values.
- Fixed the interface probe routine to only attach to USB interfaces the driver
actually supports. This allows other drivers to attach to things like
MicroSD slots etc.
- Fixed network interface enumeration to be globally sequential instead of
relying on the USB interface numbers. This make sure the first network
interface always is at uhso0 and the second at usho1 and so on.
- Added a radio kill switch; exposed through sysctl.
- Updated the manual page to be verbose about the number of serial ports and
include iCON 452 in the set of tested hardware.

take advantage of efficient synchronization for architectures that
support that feature.

too obvious, these functions are exclusively used to access memory mapped
IO in ACPICA.
According to ACPICA User Guide and Programmer Reference, the read data must
be zero extended to fill the 64-bit return value even if the bit width of
the location is less than 64.

r165114 added that code and that change ignored the same logic
committed in r135772. In addition, data FIFO protection should be
selectively enabled instead of applying to all PCIe devices.
While I'm here add BCM5785 to devices that do not require this
fix.
and remove a buffer overflow:
- Remove the array of per-type dispatch functions. Instead, pass each
structure to a single callback. The callback should check the type of
each table entry to take appropriate action. This matches the behavior
of other table walkers such as for the MP Table and MADT.
- Don't attempt to save an array of string pointers for each structure
entry. Instead, just skip the strings. If this code is reused to
provide a generic SMBIOS table walker in the future we could provide
a method that looks up a specific string N for a given structure record
instead of pre-populating an array of pointers. This fixes a buffer
overflow for structure entries with more than 20 strings.

The code in question verifies that all register write operations only change
bits that are defined (in the register definition file) for that effected
register. The bug effectively disabled this checking.
o Fix the check by testing the opcode against all supported read ("and" based)
operands.
o Add missing bit definitions to the aic7xxx and aic79xx register definition
files so that the warning (treated as a fatal error) does not spuriously
fire.
