04a1e62c2c x86/ptrace: make genregs[32]_get/set more robust
The loop condition is fragile: we compare an unsigned value to zero, and
then decrement it by something larger than one in the loop.  All the
callers should be passing in appropriately aligned buffer lengths, but
it's better to just not rely on it, and have some appropriate defensive
loop limits.

735eb93ae2 regulator: mc13783-regulator: correct the probing time.
When the mc13783-regulator driver is built in kernel, probing it during
the regulator subsystem initialisation result in a fault.

That is because regulator subsystem is planned to be initialised very early
in the boot process, before the mfd subsystem initialisation.

The mc12783-regulator probing process need to access to the mc13783-core
functionality to read/write mc13783 registers and so must be called after
the mc13783-core driver initialisation.

The way to do this is to let the kernel probe the mc13783-regulator driver when
mc13783-core register his regulator subdevice.

- properly namespace functions and structs
- fix locking as required by patch
  "mfd/mc13783: near complete rewrite"
- use platform_data as provided by "mfd/mc13783: near complete rewrite"
  instead of accessing struct mc13783
- struct mc13783_regulator_priv.desc is (and was) unused and so can go
  away
- use cpp magic to initialize mc13783_regulators
- bring MODULE_LICENSE in sync with actual copyright
- minor style fixes

This allows not including mc13783-private.h which I intend to remove
soon.

638f85c54f regulator: Handle regulators without suspend mode configuration
Since some regulators in the system may not support suspend mode
configuration we need to allow some regulators to have a missing
suspend mode configuration. Do this by requiring that disabled
regulators are explicitly flagged and then skip over regulators
that have no state specified.

Try to avoid surprises by warning the if we could set the state
but no configuration is provided.  This also ensures that an all
zeros configuration generates a warning rather than silently
disabling the regulator.

1083c39346 regulator: Factor out regulator name pretty printing
Some of the regulator API functions have code to allow the machine
constraints to override the device supplied name for the regulator
in the constraints in order to help tie logging to supplies on the
board and disambiguate when there is more than one regulator chip
in the system. Factor this code out into a new rdev_get_name()
function and use it throughout the regulator API so that we always
use the same name.

e24a04c44c regulator: Implement WM831x BuckWise DC-DC convertor DVS support
The BuckWise DC-DC convertors in WM831x devices support switching to
a second output voltage using the logic level on one of the device
pins. This is intended to allow rapid voltage switching for uses like
cpufreq, replacing the I2C or SPI write used to configure the voltage
of the regulator with a much faster GPIO status change.

This is implemented by keeping the DVS voltage configured as the
maximum voltage permitted for the regulator. If a request is made
for the maximum voltage then the GPIO is used to switch to the DVS
voltage, otherwise the normal ON voltage is updated and used. This
follows the idiom used by most cpufreq drivers, which drop the
minimum voltage as the core frequency is dropped but use a constant
maximum - raising the voltage should normally be fast, but lowering
it may be slower.

Configuration of the DVS MFP on the device should be done externally,
for example via OTP.

Support is present in the hardware for monitoring the status of the
transition using a second GPIO. This is not currently implemented
but platform data is provided for it - the driver currently assumes
that the device will be configured to transition immediately - but
platform data is provided to reduce merge issues once it is.

There is in fact one modular use of alloc_file() in the tree, in

61cf693159 [sysctl] Fix breakage on systems with older glibc
As predicted during code review, the sysctl(2) changes made systems with
old glibc nearly unusable.  About every command gives a:

  warning: process `ls' used the deprecated sysctl system call with 1.4

warning in the log.

I see this on a SUSE 10.0 system with glibc 2.3.5.

Don't warn for this common case.

3fc98b1ac0 XFS: Free buffer pages array unconditionally
The code in xfs_free_buf() only attempts to free the b_pages array if the
buffer is a page cache backed or page allocated buffer. The extra log buffer
that is used when the log wraps uses pages that are allocated to a different
log buffer, but it still has a b_pages array allocated when those pages
are associated to with the extra buffer in xfs_buf_associate_memory.

Hence we need to always attempt to free the b_pages array when tearing
down a buffer, not just on buffers that are explicitly marked as page bearing
buffers. This fixes a leak detected by the kernel memory leak code.

a5f9be58c2 xfs: kill xfs_bmbt_rec_32/64 types
For a long time we've always stored bmap btree records in the 64bit format,
so kill off the dead 32bit type, and make sure the 64bit type is named just
xfs_bmbt_rec everywhere, without any size postfix.
