Previously we've been handling udivdi3 references and wrapping
them in to div64_32() automatically. This doesn't get a lot of
use, however, and as akpm noted in the recent thread on l-k:
http://lkml.org/lkml/2007/2/27/241
we're better off simply ripping it out and going the do_div()
route if there happen to be any places that need it.

This adds support for the L-BOX RE2 router.
http://www.nttcom.co.jp/l-box/
L-BOX RE2 is a SH7751R-based router. It has CF, Cardbus, serial,
and LAN x2. This is one of the very few SH boards that a general
person can obtain now.
The L-BOX shipped with a 2.4.28 kernel, this is a rewritten patch
adding it to current git.

- pata_platform was supported in USL-5P.
- irq.c was rewritten.
- io.c was replaced with generic I/O routines.

With the GDB stub being entered via a special sysrq trigger,

This implements stricter and more compliant knightrider strobing in the

This adds preliminary support for the SH7785-based Highlander board.
Some of the Highlander support code is reordered so that most of it
can be reused directly.
This also plugs in missing SH7785 checks in the places that need it,
as this is the first board to support the CPU.

Each board sets the total number of IRQs that it's interested in via
the machvec. Previously we cared about the off vs on-chip IRQ range,
but any code relying on that is long dead. Set NR_IRQS to something
sensible given the vector range, and allow boards to cap it if they
really care.

SH7780 has a speculative execution mode where it can speculatively
perform an instruction fetch for subroutine returns, this allows it
to be enabled. There are some various pitfalls associated with this
mode, so it's left as depending on CONFIG_EXPERIMENTAL and not
enabled by default.

The kgdb thread support is woefully out of date (it predates
the pidhash), and needs a complete rewrite before it's useful
again. Just rip it out entirely.
Updating the unified kgdb stub is a more worthwhile endeavour
for anyone that happens to be interested in this, at present
it's just limping along.

* limit max PIO mode to PIO4, this driver doesn't support PIO5 and attempt
to setup PIO5 by it821x_tuneproc() could result in incorrect PIO timings
+ incorrect base clock being set for controller in the passthrough mode
* move code limiting max PIO according to the pair device capabilities from
config_it821x_chipset_for_pio() to it821x_tuneproc() so the check is also
applied for mode change requests coming through ->tuneproc and ->speedproc
interfaces
* set device speed in it821x_tuneproc()
* in it821x_tune_chipset() call it821x_tuneproc() also if the controller is
in the smart mode (so the check for pair device max PIO is done)
* rename it821x_tuneproc() to it821x_tune_pio(), then add it821x_tuneproc()
wrapper which does the max PIO mode check; it worked by the pure luck
previously, pio[4] and pio_want[4] arrays were used with index == 255
so random PIO timings and base clock were set for the controller in the
passthrough mode, thankfully PIO timings and base clock were corrected
later by config_it821x_chipset_for_pio() call (but it was not called for
PIO-only devices during resume and for user requested PIO autotuning)
* remove config_it821x_chipset_for_pio() call from config_chipset_for_dma()
as the driver sets ->autotune to 1 and ->tuneproc does the proper job now
* convert the last user of config_it821x_chipset_for_pio() to use
it821x_tuneproc(drive, 255) and remove no longer needed function

Teach the driver's tuneproc() method to do PIO auto-runing properly since it
treated 5 instead of 255 as auto-tune request, and also passed the mode limit
of PIO5 to ide_get_best_pio_mode() despite supporting up to PIO4 only.
While at it, also:
- remove the driver's wrong claim about supporting SWDMA modes;
- stop hooking ide_dma_timeout() method as the handler clearly doesn't fit for
the task...

mere call to it.
Start using faster versions of the ide_dma_end() and ide_dma_test_irq() methods
for the PCI0646U and newer chips that have the duplicate interrupt status bits
in the I/O mapped MRDMODE register, determing what methods to use at the driver
load time. Do some cleanup/renaming in the "old" ide_dma_test_irq() method too.

Fix several issues with the driver's procfs output:
- when testing if channel is enabled, the code looks at the "simplex" bits, not
at the real enable bits -- add #define for the primary channel enable bit;
- UltraDMA modes 0, 1, 3 for slave drive reported incorrectly due to using the
master drive's clock cycle resolution bit.
While at it, also perform the following cleanups:
- don't print extra newline before the first controller's dump;
- correct the chipset names (from CMDxxx to PCI-xxx)
- don't read from the registers which aren't used for dump;
- better align the table column sizes;
- rework UltraDMA mode dump code;
- remove PIO mode dump code that has never been finished;
- remove the duplicate interrupt status (the MRDMODE register bits mirror those
those in the CFR and ARTTIM23 registers) and fold the dump into single line;
- correct the style of the ?: operators...

The IDE core looks at the wrong bit when checking if the secondary channel is
enabled on PCI0646 -- CNTRL register bit 7 is read-ahead disable, bit 3 is the
correct one.
Starting with PCI0646U chip, the primary channel can also be enabled/disabled --
so, add 'enablebits' initializers to each 'ide_pci_device_t' structure, handling
the original PCI0646 via adding the init_setup() method and clearing the 'reg'
field there if necessary...
