mmc: omap_hsmmc: Avoid a regulator voltage change with dt
When booting with Device tree, the omap_hsmmc driver does not
program the pbias cell (inside OMAP control module) during
a regulator voltage change.
In case of non-dt boot, this is handled using callbacks
from within platform_data and implemented in machine code.
To be able to do this with device tree, without invoking
any machine code, a OMAP control module driver is needed
which is yet missing.
The pbias cell is used to provide a 1.8v or 3.0v reference
to the mmc/sd/sdio1 interface supporting both 1.8v and 3.0v
voltages.
Until a OMAP control module driver is available to handle this,
when booting with a device tree blob, never change the regulator
voltage which might then require a pbias cell re-program.
There are 2 instances where in the mmc regulator voltage can be
changed.
-1- when the regulator is turned OFF.
-2- when attempting a switch to 1.8v from 3.0v for dual volt cards
This patch avoids a voltage change in both cases when booting from
device tree, and hence compromises on power savings.
Once the OMAP control module driver is available and hsmmc driver
is modified to then do pbias programming even when booting
with device tree, these limitaions can be removed to achieve better
power savings.

Merge tag 'irqdomain-for-linus' of git://git.secretlab.ca/git/linux-2.6
Pull irq_domain support for all architectures from Grant Likely:
"Generialize powerpc's irq_host as irq_domain
This branch takes the PowerPC irq_host infrastructure (reverse mapping
from Linux IRQ numbers to hardware irq numbering), generalizes it,
renames it to irq_domain, and makes it available to all architectures.
Originally the plan has been to create an all-new irq_domain
implementation which addresses some of the powerpc shortcomings such
as not handling 1:1 mappings well, but doing that proved to be far
more difficult and invasive than generalizing the working code and
refactoring it in-place. So, this branch rips out the 'new'
irq_domain and replaces it with the modified powerpc version (in a
fully bisectable way of course). It converts all users over to the
new API and makes irq_domain selectable on any architecture.
No architecture is forced to enable irq_domain, but the infrastructure
is required for doing OpenFirmware style irq translations. It will
even work on SPARC even though SPARC has it's own mechanism for
translating irqs at boot time. MIPS, microblaze, embedded x86 and c6x
are converted too.
The resulting irq_domain code is probably still too verbose and can be
optimized more, but that can be done incrementally and is a task for
follow-on patches."

hfsplus: add an ioctl to bless files
Making an hfsplus partition bootable requires the ability to "bless" a
file by putting its inode number in the volume header. Doing this from
userspace on a mounted filesystem is impractical since the kernel will
write back the original values on unmount. Add an ioctl to allow userspace
to update the volume header information based on the target file.
