b6adea334c 8250: fix boot hang with serial console when using with Serial Over Lan port
Intel 8257x Ethernet boards have a feature called Serial Over Lan.

This feature works by emulating a serial port, and it is detected by
kernel as a normal 8250 port.  However, this emulation is not perfect, as
also noticed on changeset 7500b1f602.

Before this patch, the kernel were trying to check if the serial TX is
capable of work using IRQ's.

This were done with a code similar this:

        serial_outp(up, UART_IER, UART_IER_THRI);
        lsr = serial_in(up, UART_LSR);
        iir = serial_in(up, UART_IIR);
        serial_outp(up, UART_IER, 0);

        if (lsr & UART_LSR_TEMT && iir & UART_IIR_NO_INT)
		up->bugs |= UART_BUG_TXEN;

This works fine for other 8250 ports, but, on 8250-emulated SoL port, the
chip is a little lazy to down UART_IIR_NO_INT at UART_IIR register.

Due to that, UART_BUG_TXEN is sometimes enabled.  However, as TX IRQ keeps
working, and the TX polling is now enabled, the driver miss-interprets the
IRQ received later, hanging up the machine until a key is pressed at the
serial console.

This is the 6 version of this patch.  Previous versions were trying to
introduce a large enough delay between serial_outp and serial_in(up,
UART_IIR), but not taking forever.  However, the needed delay couldn't be
safely determined.

At the experimental tests, a delay of 1us solves most of the cases, but
still hangs sometimes.  Increasing the delay to 5us was better, but still
doesn't solve.  A very high delay of 50 ms seemed to work every time.

However, poking around with delays and pray for it to be enough doesn't
seem to be a good approach, even for a quirk.

So, instead of playing with random large arbitrary delays, let's just
disable UART_BUG_TXEN for all SoL ports.

pci_serial_quirks contains a number of function pointers where the referenced

cd354f1ae7 [PATCH] remove many unneeded #includes of sched.h
After Al Viro (finally) succeeded in removing the sched.h #include in module.h
recently, it makes sense again to remove other superfluous sched.h includes.
There are quite a lot of files which include it but don't actually need
anything defined in there.  Presumably these includes were once needed for
macros that used to live in sched.h, but moved to other header files in the
course of cleaning it up.

To ease the pain, this time I did not fiddle with any header files and only
removed #includes from .c-files, which tend to cause less trouble.

Compile tested against 2.6.20-rc2 and 2.6.20-rc2-mm2 (with offsets) on alpha,
arm, i386, ia64, mips, powerpc, and x86_64 with allnoconfig, defconfig,
allmodconfig, and allyesconfig as well as a few randconfigs on x86_64 and all
configs in arch/arm/configs on arm.  I also checked that no new warnings were
introduced by the patch (actually, some warnings are removed that were emitted
by unnecessarily included header files).

The JC14xx are RS422/RS485-based cards, but in order for these to be
supported natively, we will need additional tweaks to the 8250 layers so
we can specify some values for the 950's registers.  Hence, these two

3ec9c59449 [SERIAL] SIIG 8-port serial boards support
This patch adds support for SIIG 8-port boards. These boards have 4 ports in
separate bars and another 4 ports in the single bar. Because of this strange
port arrangement these cards need special setup function. Fortunately no other
SIIG cards have more than 4 port, so this setup function could be used for them
too.

d9004eb466 [SERIAL] Add 8250 support for Decision Computer International Co. PCCOM2
There is a new device which is look like:

	Serial controller: Decision Computer International Co. PCCOM2 (rev 02) (prog-if 02 [16550])
	0700: 6666:0004 (rev 02) (prog-if 02)
	Flags: medium devsel, IRQ 177
	Memory at fe000000 (32-bit, non-prefetchable) [size=128]
	I/O ports at e880 [size=128]
	I/O ports at e400 [size=256]

It has two 16550A, and is not listed in kernel, although the
manufacturer clams that it is supported...

I've created the following patch, it only add the new PCI id and the
card to the repository, it seems to work.

db1de1595d [PATCH] serial: MRi MRI-PCIDS1 dual port serial card
Add support for the MRi PCIDS1 dual port serial card.  This card is a
little controversial since it is the subject of a PCI vendor/device ID
clash.  (See
http://www.ussg.iu.edu/hypermail/linux/kernel/0303.1/0516.html).  I have
for now just used the hex ID 0x950a.  The divisor was part calculated part
iterated, so may not be exactly correct (but works for me at all settings
between 300 - 115300 bps).
