An earlier update changed some calls from simple_strotl to strict_strtol but
did not account for the differences in the syntax between the calls.
simple_strotl returns the integer; strict_strtol returns an error code and
takes a pointer to the result. As it was, NULL was being passed in place of
the result, which led to failures during kernel initialization when using
YAMON.

Fix several errors and warnings given by checkpatch.pl:
- use of C99 // comments;
- initialization of a 'static' variable to 0;
- space after opening and before closing parentheses;
- missing space between 'for' and opening parenthesis;
- macros with complex values not enclosed in parentheses;
- printk() without KERN_* facility level;
- unnecessary braces for single-statement block;
- using simple_strtol() where strict_strtol() could be used;
- line over 80 characters.
In addition to these changes, also do the following:
- mention DBAu1200 board in the Makefile;
- replace the group of #include/#ifdef directives by a single
#include <au1xxx.h> since this header contains the needed stuff;
- properly indent the blocks;
- insert spaces between operator and its operands, remove excess spaces
there;
- remove needless parentheses and add some for clarity;
- replace numeric literals/expressions with the matching macros;
- remove space after the type cast's closing parenthesis;
- reduce pb1200_setup_cascade() to the single 'return' statement;
- reduce the number of printed empty lines in the so-called CPLD
workaround;
- remove #undef AU1X00_EXTERNAL_INT since that macro is not defined
anywhere;
- replace spaces after the macro name with tabs in the #define directives;
- remove excess tabs after the macro name in the #define directives;
- fix typo in the BCSR_RESETS_PWMR1mUX macro's name;
- group all Pb1200 PCMCIA definitions together;
- put the function's result type and name/parameters on the same line;
- insert missing and remove excess new lines;
- make the multi-line comment style consistent with the kernel style
elsewhere by adding empty first line and/or adding space/asterisk on
their left side;
- fix typos/errors, capitalize acronyms, etc. in the comments;
- combine some comments;
- update MontaVista copyright;
- remove Pete Popov's old email address...

Since both the IDE interface and SMC 91C111 Ethernet chip are on-board
devices, not SOC devices, move the platform device registration form the
common to the board specific code.
While at it, remove semicolon (which didn't break compilation only by
chance) from the AU1XXX_ATA_DDMA_REQ macro and do some renaming:
- change 'au1200_ide0_' variable name prefix to the mere 'ide_';
- change 'smc91x_' variable name prefix to 'smc91c111_' since that's the
name of the chip used on the boards;
- drop 'AU1XXX_' prefix from the names of macros describing IDE and Ethernet
on-board devices;
- change 'SMC91111_' to 'SMC91C111_', change 'IRQ' to 'INT' in the names of
the macros describing the Ethernet chip for consistency with the IDE
macros;
- change 'ATA_' to 'IDE_' and 'OFFSET' to 'SHIFT' (since this value is
indeed a shift count) in the names of the macros describing the IDE
interface.

Fix havoc wrought by commit 56f621c7f6f735311eed3f36858b402013023c18 --
au_ffs() and ffs() are equivalent, that patch should have just replaced one
with another. Now replace ffs() with __ffs() which returns an unbiased bit
number.

remove asm/bitops.h includes
including asm/bitops directly may cause compile errors. don't include it
and include linux/bitops instead. next patch will deny including asm header
directly.

This patch-queue improves the generic IRQ layer to be truly generic, by adding
various abstractions and features to it, without impacting existing
functionality.
While the queue can be best described as "fix and improve everything in the
generic IRQ layer that we could think of", and thus it consists of many
smaller features and lots of cleanups, the one feature that stands out most is
the new 'irq chip' abstraction.
The irq-chip abstraction is about describing and coding and IRQ controller
driver by mapping its raw hardware capabilities [and quirks, if needed] in a
straightforward way, without having to think about "IRQ flow"
(level/edge/etc.) type of details.
This stands in contrast with the current 'irq-type' model of genirq
architectures, which 'mixes' raw hardware capabilities with 'flow' details.
The patchset supports both types of irq controller designs at once, and
converts i386 and x86_64 to the new irq-chip design.
As a bonus side-effect of the irq-chip approach, chained interrupt controllers
(master/slave PIC constructs, etc.) are now supported by design as well.
The end result of this patchset intends to be simpler architecture-level code
and more consolidation between architectures.
We reused many bits of code and many concepts from Russell King's ARM IRQ
layer, the merging of which was one of the motivations for this patchset.
This patch:
rename desc->handler to desc->chip.
Originally i did not want to do this, because it's a big patch. But having
both "desc->handler", "desc->handle_irq" and "action->handler" caused a
large degree of confusion and made the code appear alot less clean than it
truly is.
I have also attempted a dual approach as well by introducing a
desc->chip alias - but that just wasnt robust enough and broke
frequently.
So lets get over with this quickly. The conversion was done automatically
via scripts and converts all the code in the kernel.
This renaming patch is the first one amongst the patches, so that the
remaining patches can stay flexible and can be merged and split up
without having some big monolithic patch act as a merge barrier.
