Use the real-time status registers of the Winbond W83782D, W83783S and
W83627HF chips, instead of the interrupt status registers. Interrupts
cannot be trusted at least for voltage inputs, as they are two-times
triggers (as opposed to comparator mode, which we want.) The w83627hf
driver was fixed in a similar way some times ago.

- tipar_open(): fix unsigned comparison
- tipar_open(): don't permit NULL pardevice (probably unneeded given the
above fix).
- tipar_init_module(): handle the situation where parport_register_driver()
failed to register any devices (parport_register_driver() drops the ->attach
return value on the floor).
This probably makes fixes#1 and #2 unneeded.
- tipar_init_module(): fix various error-path resource leaks.

When the sclp interface takes very long to serve a request, the sclp core
driver will report a failed request to the sclp tty driver even though the
request is still being processed by the sclp interface. Eventually the sclp
interface completes the request and updates some fields in the request buffer
which leads to a corrupted tty pages list. The next time function
sclp_tty_write_room is called, the corrupted list will be traversed, resulting
in an oops.
To avoid this remove the busy retry limit and increase retry intervals.

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.

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.
