If one of the OEM flags becomes set in the flags from the hardware, the
driver could hang if no OEM handler was set. Fix the code to handle this.
This was tested by setting the flags by hand after they were fetched.

When the ipmi_si module is loaded on a system without any ipmi device, it
fails with nodev. It would be fine if all resources were freed. A call to
device_unregister() is missing, resulting to a oops when you remove the
ipmi_msghandler.

No other tty driver will print on the console when the open of it fails.
On systems that happen to be configured for both ttyS0 and hvc0 console,
this will keep flooding the console output. This is most likely to
happen with systems booted between with and without hypervisor from the
same filesystem.
Let's just remove it. When it's really needed (i.e. when the open fails
and someone is trying to debug it), noone will see the output anyway. And
init will report the opens failing in due time through the syslog.

Olaf Kirch of SuSE tracked down a problem where module unloads of the IPMI
driver would occasionally result in Oopses. He tracked that down to a
variable that wasn't always initialized properly in some situations. This
patch initializes that variable. Olaf sent a patch that kzalloc-ed the
data, but this structure is large enough that I would perfer to not do
that. Thanks Olaf!

Unlike the other tty comment patch this one has code changes. Specifically
it limits the queue size for a tty to 64K characters (128Kbytes) worst case
even if the tty is ignoring tty->throttle. This is because certain drivers
don't honour the throttle value correctly, although it is a useful
safeguard anyway.

When reading /dev/vcsa while a font with more than 256 characters is
loaded, one of the attribute bits records the 9th bit of the character.
But depending on the console driver (vgacon or fbcon for instance), that's
bit 3 or bit 0. And there is no way for userland to know that, thus no way
for userland to safely grab the screen content. So here is a (tested)
patch:
Add a VT_GETHIFONTMASK ioctl for knowing which bit is the 9th bit for VC
text (vc_hi_font_mask field of the vc_data structure).

While testing Moxa C218T/PCI on PowerPC 405EP I found that loading firmware
using the linux kernel driver fails because calculation of the checksum is
not endianess independent in the original code.
After I fixed this I found that uploading firmware in a system with
multiple cards causes a kernel oops. I had a look in the recent moxa
sources and found that they do some kind of locking there. Applying this
lock fixed the problem.
Alan sayeth:
Checksum changes are clearly correct. Other changes is an improvement but
not I think enough to handle malicious firmware attacks. That said such an
attacker has CAP_SYS_RAWIO anyway so that part is irrelevant except for
neatness.

A set of tty line discipline cleanup patches were introduced before the
dawn of time, in kernel version 2.4.21. This patch performs that cleanup
for the hvsi driver.
The hvsi driver is used only on IBM pSeries PowerPC boxes. The driver was
originally written by Hollis Blanchard, who has delegated maintainership to
me. So this my first and maybe only patch in this official new role,
because this driver is otherwise bug-free :-)
Alan: "Actually its also a bug fix, tty->ldisc should be locked by refcounting
and the helpers do this for you."

Remove the scx200_gpio's cdev-array & ksalloc, replacing it with a single
static struct cdev, which is sufficient for all the pins.
cdev_put is commented out since kernel wont link properly with it, and its
apparently not needed.

this patch is mostly cleanup of scx200_gpio :
- drop #include <linux/config.h>
- s/DEVNAME/DRVNAME/ apparently a convention
- replace variable num_pins with #define MAX_PINS
- s/dev/devid/ to clarify that its a dev_t, not a struct device dev.
- move devid = MKDEV(major,0) into branch where its needed.
2 minor 'changes' :
- reduced MAX_PINS from 64 to 32. Ive never tested other pins, and
theyre all multiplexed with other functions, some of which may be in use
on my soekris 4801, so I dont know what testing should yield.
- +EXPORT_SYMBOL(scx200_access);
This exposes the driver's vtable, which another driver can use along
with #include <linux/nsc_gpio.h>, to manipulate a gpio-pin.
