Supply the old termios, along with the max and min acceptable baud
rate to uart_get_baud_rate().  uart_get_baud_rate() will now try to
find a baud rate that satisfies the max and min constraint out of
(requested rate, old rate, 9600 baud).

We remove the code which performed a similar act in uart_get_divisor()
and pass an appropriate min and max baud rate to uart_get_baud_rate()
based on the UART clock rate.

set_termios matches the style used for the other methods.  It should
have been this from the start.

Several serial drivers want to obtain the numeric baud rate when
configuring their serial ports.  Currently, two methods are used
to "work around" this inadequacy in the change_speed API:

	baud = tty_get_baud_rate(port->info->tty);

	baud = BAUD_BASE / (16 * quot);

Passing the termios structure down means that we can use 
uart_get_baud_rate() instead.  We can also ensure that the various
termios flags for options we don't support are correctly set.

Lastly, this also provides 8250.c with a clean method for supporting
divisors that are greater than the baud_base.

UPF_FLAGS is confusing - rename it to UPF_CHANGE_MASK.
Add uart_update_timeout, uart_get_baud_rate and uart_get_divisor
prototypes.

Use ".init.plt" section consistently, and mark plt sections executable.

I've merged changes from both 2.4 and 2.5 with direct submissions to my
repository and deleted a few entries which are obviously wrong.

The attached patch fixes the crash top or cat /proc/*/wchan produces
when using KALLSYMS it's a buffer overrun that should not happen.

This was originally added in rev 1.26.1.2, then dropped 
during a merge in rev 1.33.  Please be more careful with
those merges, people.

This patch adds support for enable/disable_irq_wake for the SA11x0
CPUs, allowing drivers or other code to select which IRQs are able
to wake the CPU from sleep mode.

This brings the ARM dma mapping functionality into line with
the current generic interface, allowing any struct device to
be passed into the dma_* functions.

Further cleanups will be possible when the USB layer is
converted to use the dma_* API.

RTH's final complaint (so far 8) was that we should sort the module
sections: archs might require some sections to be adjacent, so they can
all be reached by a relative pointer (ie.  GOT pointer).  This
implements that reordering, and simplfies the module interface for
architectures as well.

Previously an arch could specify it wanted extra space, but not where
that space would be.  The new method (used only by PPC so far) is to
allocate an empty section (in asm/module.h or by setting LDFLAGS_MODULE
to use an arch specific linker script), and expand that to the desired
size in "module_frob_arch_sections()".

From: Richard Henderson <rth@twiddle.net>

Richard points out that we should be using sh_addr to hold the address,

The original patch used to overload sh_offset to a pointer to the
location of the section.  This uses sh_addr, which is more correct
and less surprising.

As RTH pointed out, we use -fno-common for the kernel (otherwise we'd
have to sort out the small symbols anyway).

So the common section allocation in the module code is pointless.

Only set IRQ type after a successful request_irq().
Driver now known as sa1111-pcmcia in driverfs.

- Add missing include files.
- Fail to set pcmcia socket state for invalid socket numbers.
- Fix locla_ typo.
- Make pcmcia_jornada720_exit __devexit, not __exit.
- Don't initialise jornada720 machine specifics if not running
  on jornada720.

bios32.c uses outb(), and therefore should have asm/io.h included.
