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...)

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

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.)

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.

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.)

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
