Serial drivers in general should not write uart_info->flags - they're
private to serial_core. Serial drivers have no need to fiddle with
tty->alt_speed, nor manipulate TTY_IO_ERROR in tty->flags. Fix the
ioc4 serial driver for both these points by simply removing the
offending code.

This patch contains help text updates including the following:
- XFree86 * -> X

option and having "If unsure, say Y/N." in the chip specific
options.

Prevent stalled processing of received data when a driver allocates tty
buffer space but does not immediately follow the allocation with more data
and a call to schedule receive tty processing. (example: hvc_console) This
bug was introduced by the first locking patch for the new tty buffering.

On some embedded PowerPC (MPC834x) systems an extra byte would some
times be required to flush data out of the fifo.
serial8250_console_write() was updating the IER in hardware without
also updating the copy in uart_8250_port. This causes issues functions
like serial8250_start_tx() and __stop_tx() to misbehave.

This patch adds a windfarm module, windfarm_pm112, for the dual core G5s
(both 2 and 4 core models), keeping the machine from getting into
vacuum-cleaner mode ;) For proper credits, the patch was initially
written by Paul Mackerras, and slightly reworked by me to add overtemp
handling among others. The patch also removes the sysfs attributes from
windfarm_pm81 and windfarm_pm91 and instead adds code to the windfarm
core to automagically expose attributes for sensor & controls.

MTD_XIP depends on having working asm/mtd-xip.h; it's not just per-architecture

well. Introduced a new symbol (ARCH_MTD_XIP) set by arch Kconfig; MTD_XIP
depends on it.

Further, there's an additional issue that I saw in testing:
ipoib_mcast_send may get called when priv->broadcast is NULL (e.g. if
the device was downed and then upped internally because of a port
event).
If this happends and the send-only join request gets completed before
priv->broadcast is set, we get an oops.

Fix the following race scenario:
- Device is up.
- Port event or set mcast list triggers ipoib_mcast_stop_thread,
this cancels the query and waits on mcast "done" completion.
- Completion is called and "done" is set.
- Meanwhile, ipoib_mcast_send arrives and starts a new query,
re-initializing "done".
Fix this by adding a "multicast started" bit and checking it before
starting a send-only join.

This does not show up unless you #define DEBUG in the file, which most
people wouldn't do. On PPC405, at least, "sector_t" is unsigned long,
which doesn't match %llx/%llu. Since sector# may well be >32 bits, promote
the value to match the format.

The at76c651 and tda80xx frontends are currently completely unused, IOW
their only effect is making the kernel larger for people accitentially
enabling them.
