Update sa1100_ir to use new dma-mapping subsystem.  Register a
system device for the SIR/FIR uart port, and a device driver for
this driver.

set_irq_type is redundant for many SA1111 drivers.  The active edge
is setup by the core SA1111 code for the common case.

SA1111 driver names are lower case.  Make the sa1111 ohci driver
reflect this.

Add sa1100_wdt watchdog support.

Remove the pci_dma functionality from the Acorn SCSI drivers, and
replace with the new DMA API, passing in the generic struct device.

Add 00-INDEX and booting documentation, remove obsolete DMA
documentation.

This adds knowledge of the relevant Intel errata

-	450NX rev B0 we must not do IDE DMA
-	450NX rev C0 we must ensure restreaming is off or risk corruption
-	ICH0-ICH2 have a data corrupting hardware bug in the old old MWDMA0
	mode, so we avoid MWDMA0 on such devices

Add empty statements to avoid warning.

This also avoids the nasty warnings that nobody seems to bother
to fix.

programs still depend on it and in fact do install a different signal
restorer than the standard kernel version.

At bootup, one_page_table_init() pulls the rug out from under the kernel
by installing a new page table before setting it up.  With big TLB's, it
can go unnoticed, but a 486 has a small TLB so any miss will cause a
triple fault and reset.

cpu-sa11x0: CPUFREQ_ALL_CPUS shouldn't be passed as argument to
cpufreq_notify_transition() any more, but the exact CPU number.

mach-integrator: cpufreq_notify_transition() isn't called -- which
means that the transition notifiers are not informed. This patch adds
these callbacks. Also, CPUFREQ_ALL_CPUS can't passed to
cpufreq_driver->set_policy any longer, so some code can safely be
removed.

The patch below removes #if'd kernel 2.0 code from
drivers/isdn/divert/divert_init.c.

This patch makes isdn_tty HZ aware.
The first change changes 3000 jiffies (now 3 seconds) to 30 seconds according to
the comment.
I dont know, if the second change (schedule_timeout(50);) has to be half a
second but this was the value used in 2.4.

Instead of having "switch (subtype)" in just about every function,
rather use separate functions and invoke the right one using
the now existing struct card_ops infrastructure.

All IRQ handlers for IPAC based cards were basically the same (not
a big surprise, since the chip is the same), so we can share
the IRQ handler.

IPAC is basically a combined HSCX/ISAC chip, so we can generate
the D- and B-channel access functions knowing how to access the IPAC.
  
For performance reasons, this happens in a macro.

Just renaming and introducing some helpers makes them look very similar
to each other..

Except for a minor performance penalty, using the same IRQ handler
for cards which used the same code anyway seems perfectly natural...

Again, just killing some duplicated code.

Same change which happened for the B-channel earlier.

This mostly finishes splitting up the multiplexing ->cardmsg.

Since we now have a per-card ops struct, use it to provide the
irq handler function, too.

Some drivers actually drive more than one specific hardware card,
instead of having "switch (cs->subtyp)" scattered around, we rather
aim at having different card_ops structures which just provide the
right functions for the hardware. Of course, this patch is only the
beginning of that separation, but allows for some cleaning already.

Linux normally uses separate callbacks instead of a multiplexing
function like "cardmsg". So start to break that into pieces.

The patch arranges for constant 1, 2 and 4-byte copy_*_user() invokations to
be inlined.

It's hard to tell really, but the AIM9 creat_clo, signal_test and dir_rtns_1
numbers went up by 3%-9%, which is to be expected.

set_page_dirty() is racy if the caller has no reference against
page->mapping->host, and if the page is unlocked.  This is because
another CPU could truncate the page off the mapping and then free the
mapping.

Usually, the page _is_ locked, or the caller is a user-space process which
holds a reference on the inode by having an open file.

The exceptional cases are where the page was obtained via
get_user_pages().  The patch changes those to lock the page around the
set_page_dirty() call.
