The bug was in fb_ddc and was fixed by commit
b64d70825abbf706bbe80be1b11b09514b71f45e (fb_ddc: fix DDC lines quirk) so
the workaround in radeonfb can be removed now.

Add a new internal mechanism to gpiolib to support low power
operations by letting gpio_chip instances see when their GPIOs
are in use. When no GPIOs are active, chips may be able to
enter lower powered runtime states by disabling clocks and/or
power domains.

This updates most of the OMAP drivers which are in mainline to switch to
using the cross-platform GPIO calls instead of the older OMAP-specific
ones.
This is all fairly brainless/obvious stuff. Probably the most interesting
bit is to observe that the omap-keypad code seems to now have a portable
core that could work with non-OMAP matrix keypads. (That would improve
with hardware IRQ debouncing enabled, of course...)

Add a new gpiolib mechanism: gpio_chip instances can provide mappings
between their (input) GPIOs and any associated IRQs. This makes it easier
for platforms to support IRQs that are provided by board-specific external
chips instead of as part of their core (such as SOC-integrated GPIOs).
Also update the irq_to_gpio() description, saying to avoid it because it's
not always supported.

Make the I2C external GPIO expander drivers register themselves at
subsys_initcall() time when they're statically linked.
SOC-integrated GPIOs are available starting very early -- early in
arch_initcall() at latest, but often even before initcalls start to run --
so this improves consistency, so more subsystems can rely on GPIOs in
their own subsys_initcall() code.
(This isn't a theoretical problem. This is one of several patches needed
to resolve oopsing observed when statically linking kernels on a DaVinci
EVM. Its pcf857x GPIOs needed to be available well before some other
drivers initialized.)

Add support for M41T65 Real Time Clock chip.
The main differences I see between the M41T65 and M41T80 are that:
1) The M41T65 watchdog timer has three bits controlling resolution
(versus two for the M41T80).
2) There is no register 0x13 for controlling square-wave output.

Make the rtc framework consistent about disabling 1/second update IRQs
that may have been activated through the /dev interface, when that /dev
file is closed. (It may have closed because of coredump, etc.) This was
previously done only for emulated update IRQs ... now, do it always.
Also comment the current policy: repeating IRQs (periodic, update) that
userspace enabled will be cleanly disabled, but alarms are left alone.
Such repeating IRQs are a constant and pointless system load.
Update some RTC drivers to remove now-needless release() methods. Most
such methods just enforce that policy. The others all seem to be buggy,
and mistreat in-kernel clients of periodic or alarm IRQs.

Ricoh Japan and described at:
http://www.ricoh.co.jp/LSI/product_rtc/2wire/r2025x/

rtc-rs5c372 presently depends on I2C master mode transfers, despite the
fact that these RTCs frequently find themselves on SMBus-only adapters.
Given that the only capabilities that were checked were for I2C_FUNC_I2C,
it's assumed that most of the adapters that are currently using this
driver are fairly sane, and are able to handle SMBus emulation (though we
adjust the default capabilities to check for I2C_FUNC_SMBUS_EMUL anyways,
which is the vast majority of them. The adapters that don't have their
own ->smbus_xfer() fall back on the ->master_xfer() through the emulated
transfer).
The special case is iop3xx, which has more than its fair share of hacks
within this driver, it remains untested -- though also claims to support
emulated SMBus accesses. The corner case there is rs5c_get_regs() which
uses access mode #3 for transferring the register state, while we use mode
#1 for SMBus.

HPET_RTC_IRQ is no longer needed; HPET_EMULATE_RTC suffices and is more
correct. (http://bugzilla.kernel.org/show_bug.cgi?id=11111)
Note that when using the legacy RTC driver, platforms don't really do a
dynamic switch between HPET and non-HPET modes based on whether HPET
hardware actually exists ... only rtc-cmos (using the new RTC framework)
currently switches that way.
So this reflects bitrot in that legacy code, for x86/ia64: kernels with
HPET support configured (e.g. for a clocksource) can't get IRQs from the
legacy RTC driver unless they really have HPET hardware. (The obvious
workaround is to not use the legacy RTC driver on those platforms when you
configure HPET ... unless you know the target really has a HPET.)

Add a miscellaneous device to the autofs4 module for routing ioctls. This
provides the ability to obtain an ioctl file handle for an autofs mount
point that is possibly covered by another mount.
The actual problem with autofs is that it can't reconnect to existing
mounts. Immediately one things of just adding the ability to remount
autofs file systems would solve it, but alas, that can't work. This is
because autofs direct mounts and the implementation of "on demand mount
and expire" of nested mount trees have the file system mounted on top of
the mount trigger dentry.
To resolve this a miscellaneous device node for routing ioctl commands to
these mount points has been implemented in the autofs4 kernel module and a
library added to autofs. This provides the ability to open a file
descriptor for these over mounted autofs mount points.
Please refer to Documentation/filesystems/autofs4-mount-control.txt for a
discussion of the problem, implementation alternatives considered and a
description of the interface.

The I2O ioctls assume 32bits. In itself that is fine as they are old
cards and nobody uses 64bit. However on LKML it was noted this
assumption is also made for allocated memory and is unsafe on 64bit
systems.
Fixing this is a mess. It turns out there is tons of crap buried in a
header file that does racy 32/64bit filtering on the masks.
So we:
- Verify all callers of the racy code can sleep (i2o_dma_[re]alloc)
- Move the code into a new i2o/memory.c file
- Remove the gfp_mask argument so nobody can try and misuse the function
- Wrap a mutex around the problem area (a single mutex is easy to do and
none of this is performance relevant)
- Switch the remaining problem kmalloc holdout to use i2o_dma_alloc

Make the SPI external GPIO expander drivers register themselves at
subsys_initcall() time when they're statically linked, and make the SPI
core do its driver model initialization earlier so that's safe.
SOC-integrated GPIOs are available starting very early -- often before
initcalls start to run, or earily in arch_initcall() at latest -- so this
improves consistency, letting more subsystems rely on GPIOs being usable
by their own subsys_initcall() code.

We are missing 'simple' values which include square brackets. Refactor to
ensure we handle nesting correctly and detect these simple forms.

When we hit and #else or #elif we know we are meeting an alternative piece
of code. All bets are off on indent if we did not see the open of the
control so stop checking.

Within the type checker we have a number of common kernel types which must
be implemented as typedefs. Pull those out so that we can use the same
expressions to trigger exclusions.

We are likely going to have 24 bit types. Expand the type matcher to
match any size.

We often see macros which define structure members, these are not complex
and necessarily do not have braces or brackets. For example:
#define _PLIST_HEAD_INIT(head) \
.prio_list = LIST_HEAD_INIT((head).prio_list), \
.node_list = LIST_HEAD_INIT((head).node_list)
