A serial card might have been removed when the system is resumed.
This results in a suspended port being shut down, which results in
the ports shutdown method being called twice in a row.  This causes
BUGs.  Avoid this by tracking the suspended state separately from
the initialised state.

Unfortunately, pcmcia_dev_present() returns false when a device is
suspended, so checking this on resume does not work too well.  Omit
this test.

asm/serial.h is supposed to contain the definitions for the architecture
specific 8250 ports for the 8250 driver.  It may also define BASE_BAUD,
but this is the base baud for the architecture specific ports _only_.

Therefore, nothing other than the 8250 driver should be including this
header file.  In order to move towards this goal, here is a patch which
removes some of the more obvious incorrect includes of the file.

The patch below is necessary for 115200 baud on an OMAP1510 internal UART.
It's been in the linux-omap tree for some time and with it applied to a
vanilla Linus git tree the serial console on the Amstrad Delta (which is
OMAP1510 based and whose initial bootloader runs at 115200) works fine (it
doesn't without it).

According to the existing code, Nokia only make single-port cards,
but are detected as multi-port cards.  Handle this in roughly the
same way via the config quirk - forcing it to be a real single port
card (info->multi=0) changes the way we allocate the IO memory,
which might stop the card working.

- rename multi_id table to serial_quirk / quirks[]
- use named initialisers
- store a pointer to the quirk table in the serial_info structure

- apply multi-port quirk after the multi-port guessing code,
  but only if it's != -1.

m32r_sio re-uses a custom defined BASE_BAUD from asm/serial.h,
and replaces SERIAL_PORT_DFNS with its own driver private copy.
Since asm/serial.h is supposed to define 8250-based ports using
these symbols, this isn't a sane idea.

Hence, eliminate asm/serial.h from m32r_sio.c.

We only need the timestamp on COOKIE-ECHO chunks, so instead of always
timestamping every SCTP packet, let common code timestamp if the socket
option is set.  For COOKIE-ECHO, simply get the time of day if we don't
have a timestamp.  This introduces a small possibility that the cookie
may be considered expired, but it will be renegotiated.

Currently if the sender is sending small messages, it can cause a receiver
to run out of receive buffer space even when the advertised receive window
is still open and results in packet drops and retransmissions. Including
a overhead while updating the sender's view of peer receive window will
reduce the chances of receive buffer space overshooting the receive window.

MSI is defined to be 32-bit write.  The 5706 does 64-bit MSI writes
with byte enables disabled on the unused 32-bit word.  This is legal
but causes problems on the AMD 8132 which will eventually stop
responding after a while.

Without this patch, the MSI test done by the driver during open will
pass, but MSI will eventually stop working after a few MSIs are
written by the device.

AMD believes this incompatibility is unique to the 5706, and
prefers to locally disable MSI rather than globally disabling it
using pci_msi_quirk.
