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.

Several bug reports have come in, noting that disabling CONFIG_PCI_MSI
has fixed their problems with this driver. This may be generic system
issues, but there is also the probability of unimplemented hardware
errata workarounds. Until this ream of bug reports is sorted out, we
can get them going in non-MSI interrupt mode.
As such, this change adds an 'msi' module option, which defaults to off.

On occasion, a user will submit a patch that enables the "mod15write"
quirk for their device. Enabling this quirk has the effect of clamping
all ATA commands to no more than 15 sectors. The intended use of this
quirk is to stop the controller from generating FIS's of unusual size
("but Wesley, what about the FOUS's?"), which in turn works around
problems in a <list> of hard drives.
One side effect of this quirk is greatly decreased performance. Users
often enable the mod15write quirk to fix various system, power, chip,
and/or driver problems. For a few rare problematic cases, enabling this
has cured lockups or data corruption.
Rather than add bogus listings to the mod15write quirk list (I get a
patch every month doing such), we add a 'slow_down' module parameter.
This allows users to employ a performance sledgehammer in the hopes
of curing a problem. It defaults to off (0), of course.

There were two problems with enabling the PRINTK_TIME config
option:
1) The first calls to printk() occur before per-cpu data virtual
address is pinned into the TLB, so sched_clock() can fault.
2) sched_clock() is based on ar.itc, which may not be synchronized
across cpus.
Ken Chen started this patch, Tony Luck tinkered with it, and Jes
Sorensen perfected it.

If you set network interface down and up again, the IPv6 address
autoconfiguration does not work. 'ip addr' shows that the link-local
address is in tentative state. We don't even react to periodical router
advertisements.
During NETDEV_DOWN we clear IF_READY, and we don't set it back in
NETDEV_UP. While starting to perform DAD on the link-local address, we
notice that the device is not in IF_READY, and we abort autoconfiguration
process (which would eventually send router solicitations).

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.

Patch from Nicolas Pitre
Since:
if (unlikely(__res || __ex_flag))
produces worse code on ARM than:
if (unlikely(__res | __ex_flag))
I therefore made it more explicit:
__res |= __ex_flag;
if (unlikely(__res != 0))
so it is not seen as a typo again.
Also made everything static inline rather than macros for better readability
(both produce the same code after all).
And finally added missing \t from multi-line assembly code.

The pre ARMv5 implementation can be aborted if an exception occurs in

Patch from Nicolas Pitre
The cmpxchg emulation on pre-ARMv5 relies on user code executed from a
kernel address. If the operation cannot complete atomically, it is
aborted from the usr_entry macro by clearing the Z flag. This clearing
of the Z flag is done whenever the user pc is above TASK_SIZE.
However this "pc >= TASK_SIZE" test cannot work in the non MMU case.
Worse: the current code will corrupt the Z flag on every entry to the
kernel.
Let's disable it in the non MMU case for now. Using NPTL on non MMU
targets needs to be worked out anyway.
