e7a46b4d08 atm: expose ATM device index in sysfs
It's currently exposed only through /proc which, besides requiring
screen-scraping, doesn't allow userspace to distinguish between two
identical ATM adapters with different ATM indexes.  The ATM device index
is required when using PPPoATM on a system with multiple ATM adapters.

8d08dab786 eCryptfs: Allow 2 scatterlist entries for encrypted filenames
The buffers allocated while encrypting and decrypting long filenames can
sometimes straddle two pages. In this situation, virt_to_scatterlist()
will return -ENOMEM, causing the operation to fail and the user will get
scary error messages in their logs:

kernel: ecryptfs_write_tag_70_packet: Internal error whilst attempting
to convert filename memory to scatterlist; expected rc = 1; got rc =
[-12]. block_aligned_filename_size = [272]
kernel: ecryptfs_encrypt_filename: Error attempting to generate tag 70
packet; rc = [-12]
kernel: ecryptfs_encrypt_and_encode_filename: Error attempting to
encrypt filename; rc = [-12]
kernel: ecryptfs_lookup: Error attempting to encrypt and encode
filename; rc = [-12]

The solution is to allow up to 2 scatterlist entries to be used.

Return -ENODATA when trying to read a user.* attribute which cannot

Likewise, return -ENODATA when an unprivileged process tries to read a

invisible (listxattr() won't include them).

However this is a fix to avoid kernel errors. In the long term another solution

aa38572954 fs: pass exact type of data dirties to ->dirty_inode
Tell the filesystem if we just updated timestamp (I_DIRTY_SYNC) or
anything else, so that the filesystem can track internally if it
needs to push out a transaction for fdatasync or not.

This is just the prototype change with no user for it yet.  I plan
to push large XFS changes for the next merge window, and getting
this trivial infrastructure in this window would help a lot to avoid
tree interdependencies.

Also remove incorrect comments that ->dirty_inode can't block.  That
has been changed a long time ago, and many implementations rely on it.

4d94aee577 REGULATOR: TWL6025: add support to twl-regulator
Adding support for the twl6025. Major difference in the twl6025 is the
group functionality has been removed from the chip so this affects how
regulators are enabled and disabled.

The names of the regulators also changed.

The DCDCs of the 6025 are software controllable as well.

Since V1

Use the features variable passed via platform data instead of calling
global function.

Change the very switch like if statements to be a more readable
switch statement.

Since V2

twl6025 doesn't use remap so remove it from the macros.

Since V3

enable/disable functions for 4030/6030 were seperated upstream so rebase
on top of this. Change DCDC reference to SMPS as this is used in TRM.
Change list_voltage slightly to have less code.

ecb9c4f595 regulator: Remove MAX8997_REG_BUCK1DVS/MAX8997_REG_BUCK2DVS/MAX8997_REG_BUCK5DVS macros
In current implementation, the original macro implementation assumes the caller
pass the parameter starting from 1 (to match the register names in datasheet).
Thus we have unneeded plus one then minus one operations

This patch removes these macros to avoid unneeded plus one then minus one operations

4aa922c024 regulator: Only apply voltage constraints from consumers that set them
When applying the set_voltage() requests from consumers skip over those
consumers that haven't set anything, otherwise we'll come out with a
maximum voltage of zero.

a4b4148379 regulator: If we can't configure optimum mode we're always in the best one
If either a regulator driver can't tell us what the optimum mode is (or
doesn't have modes in the first place) or the system doesn't allow DRMS
changes then it's more helpful for users to just say that we're in the
optimal mode, even if it's from a selection of one.

Still report errors if the process of picking and setting a mode changes as
this may indicate that we're stuck in a low power mode and unable to deliver
a higher current that the consumer just asked for.

77fa44d0e1 regulator: Fix desc_id for tps65023/6507x/65910
The desc_id variable should not be a static variable.

The rest of the code assumes the desc_id must less than TPSxxxxx_NUM_REGULATOR.
If we set desc_id to be a static variable, checking the return value of
rdev_get_id() may return error.

Following patch should fix the dependency problems. Please review:

From: Jorge Eduardo Candelaria <jedu@slimlogic.co.uk>
[PATCH] MFD: TPS65910: Fix I2C dependency

TPS65910 driver can only be compiled built-in, so the I2C driver
should be as well.

327e15af15 Revert "regulator: Move VCOINCELL to be the last element of mc13892_regulators array"
I check this patch again and found this actually is not a bug
because MC13xxx_DEFINE explictly defines the order of each entry in the array.

Thus revert the patch.

The following patch should solve this:

From: Jorge Eduardo Candelaria <jedu@slimlogic.co.uk>
MFD: Fix TPS65910 build

Support for tps65910 as a module is not available. The driver can
only be compiled as built-in. OTOH, the regulator driver can still
be built as module without breaking the compilation.
