5e54f665f0 - Found bug in min split point bundling which caused
incorrect, non-bundlable fragmentation.
- Added min residual to better control split points for
  both how big a msg must be as well as how much needs
  to be left over.
- With our new algo in place, we need to implicitly
  set "end of msg" on the sp-> structure otherwise we
  end up with "hung" associations.
- Room reserved up front in IP header by pushing IP
  header to back of mbuf.
- Fix so FR's peg count of retransmissions needed.
- Fix so an unlucky chunk that never gets across
  will kill the assoc via the kill timer and send an
  abort too.
- Fix bug in sctp_input which can result in a crash.
- Do not strip off IP options anymore.
- Clean up sctp_calculate_rto().
- Get rid of unused sysctl.
- Fixed so we discard all M-Cast
- Fixed so port check done AFTER checksum
- Fixed bug in fragmentation code that prevented
  us from fragmenting a small complete message when
  we needed to.
- Window probes were not marked back to unsent and
  flight adjusted when a sack came in with no
  window change or accepting of the probe data.
  We now fix this with having a mark on the net and
  the chunk so we can clear it out when the sack arrives
  forcing it to retran just like it was "new" this
  improves the handling of window probes, which were
  dropped by the receiver.
- Tighten AUTH protocol error checks during INIT/INIT-ACK exchange

bc5676e30c RTC_TIMR's RTC_SEC field is BCD. That makes it unsuitable for
GetSeconds().  Instead, use CRTR register shifted right 15.  This
gives us a range of 32 seconds we can do for timeout.

Shift to using == rather than < or > for calculating the timeout,
since if we can't read the ST_CTRT register twice in a second we have
even bigger problems to worry about, and == deals with the 'wrap'
issue.

This lets me type at the boot2 prompt again!  Woo Hoo!

304d0536ab All SD cards have a block size of 512. The READ_BL_LEN field in the
CSD is usually 512 (well, 9), but for 2GB (and the rogue 4GB SD cards)
it is 1024 (or 2048 for 4GB).  This value doesn't work for the block
read commands (which really want 512).  Hardcode 512 for those.  This
may break really old MMC cards that don't have a 512 block size (I've
never seen one: make my day and send me one :-), but since the MMC
side of the house is currently broken, it should only have the effect
that 2GB (and non-conforming 4GB) SD cards will work.

My 'non-conforming' 4GB SD card also works now too.  The
non-conforming 4GB SD cards were sold for a while before the SD
association was worried they would be (a) incompatible (different FAT
flavor on them) and (b) confusing for the new SDHC standard and
cracked down on suppliers' bogus use of the SD trademark...

	I also changed the strcpy of kname, so that it only happens if

ebecffe930 For embedded UARTs compatible with the ns8250 family it is possible
that the driver clock is identical to the processor or bus clock.
This is the case for the PowerQUICC processor. When the clock is
high enough, overflows happen in the calculation of the time it
takes to send 1/10 of a character, used in delay loops. Fix the
overflows so as to fix bugs in the delay loops that can cause either
insufficient delays or excessive delays.

1c5e367bcc When we match UARTs found during bus-enumeration with UARTs used for
system devices (i.e. console, debug port or keyboard), don't stop
after the first match. Find them all and keep track of the last.
The reason for this change is that the low-level console is always
added to the list of system devices first, with other devices added
later. Since new devices are added to the list at the head, we have
the console always at the end. When a debug port is using the same
UART as the console, we would previously mark the "newbus" UART as
a debug port instead of as a console. This would later result in a
panic because no "newbus" device was associated with the console.
By matching all possible system devices we would mark the "newbus"
UART as a console and not as a debug port.
While it is arguably better to be able to mark a "newbus" UART as
both console and debug port, this fix is lightweight and allows
a single UART to be used as the console as well as a debug port
with only the aesthetic bug of not telling the user about it also
being a debug port.

Now that we match all possible system devices, update the rclk of
the system devices with the rclk that was obtained through the
bus attachment. It is generally true that clock information is
more reliable when obtained from the parent bus than by means of
some hardcoded or assumed value used early in the boot. This by
virtue of having more context information.
