Phoenix Lite is based on the twl6030 family of PMICs. It has mostly the
same feature set of twl6030 but with small changes. The codec block has
also been removed. It also has a new charger block and new features in
its ADC block. VUSB handling also differs.

Add support for the irq controller in Qualcomm 8xxx pmic. The 8xxx
interrupt controller provides control for gpio and mpp configured as
interrupts in addition to other subdevice interrupts. The interrupt
controller also provides a way to read the real time status of an
interrupt. This real time status is the only way one can get the
input values of gpio and mpp lines.

Allow the GPIO mode of WM831x devices to be configured using platform data.
Users may provide a table of GPIO register values in gpio_defaults[]. In
order to allow 0 to be set explicitly out of range values are accepted and
masked off, with a WM831X_GPIO_CONFIGURE define provided to set an out of
range value.
This can be used to configure higher numbered GPIOs or override values set
in OTP for GPIOs configured using OTP.

Cell pointers are passed through device->mfd_cell and platform data
is passed through the MFD cell platform_data pointer.
Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>

With the addition of a platform device mfd_cell pointer, MFD drivers
can go back to passing platform data back to their sub drivers.
This allows for an mfd_cell->mfd_data removal and thus keep the sub drivers
MFD agnostic. This is mostly needed for non MFD aware sub drivers.

Now that we have a way to pass MFD cells down to the sub drivers,
we can gradually get rid of mfd_data by putting the platform pointer

There is quite a lot of code which does copy_from_user() + strict_strto*()
or simple_strto*() combo in slightly different ways.
Before doing conversions all over tree, let's get final API correct.
Enter kstrtoull_from_user() and friends.
Typical code which uses them looks very simple:
TYPE val;
int rv;
rv = kstrtoTYPE_from_user(buf, count, 0, &val);
if (rv < 0)
return rv;
[use val]
return count;
There is a tiny semantic difference from the plain kstrto*() API -- the
latter allows any amount of leading zeroes, while the former copies data
into buffer on stack and thus allows leading zeroes as long as it fits
into buffer.
This shouldn't be a problem for typical usecase "echo 42 > /proc/x".
The point is to make reading one integer from userspace _very_ simple and
very bug free.

This function makes a deep copy of the platform data to allow it to live
in init memory. For a kernel that supports several machines and so
includes the definition for several leds-gpio devices this saves quite
some memory because all but one definition can be free'd after boot.
As the function is used by arch code it must be builtin and so cannot go
into leds-gpio.c.

Allow unused leds on pca9532 to be used as gpio. The board I am working
on now has no less than 6 pca9532 chips. One chips is used for only leds,
one has 14 leds and 2 gpio and the rest of the chips are gpio only.
There is also one board in mainline which could use this capabilty;
arch/arm/mach-iop32x/n2100.c
232 { .type = PCA9532_TYPE_NONE }, /* power OFF gpio */
233 { .type = PCA9532_TYPE_NONE }, /* reset gpio */
This patch defines a new pin type, PCA9532_TYPE_GPIO, and registers a
gpiochip if any pin has this type set. The gpio will registers all chip
pins but will filter on gpio_request.

On larger systems, because of the numerous ACPI, Bootmem and EFI messages,
the static log buffer overflows before the larger one specified by the
log_buf_len param is allocated. Minimize the overflow by allocating the
new log buffer as soon as possible.
On kernels without memblock, a later call to setup_log_buf from
kernel/init.c is the fallback.

On larger systems, information in the kernel log is lost because there is
so much early text printed, that it overflows the static log buffer before
the log_buf_len kernel parameter can be processed, and a bigger log buffer
allocated.
Distros are relunctant to increase memory usage by increasing the size of
the static log buffer, so minimize the problem by allocating the new log
buffer as early as possible.
This patch:
Add an error return if CONFIG_HAVE_MEMBLOCK is not set instead of having
to add #ifdef CONFIG_HAVE_MEMBLOCK around blocks of code calling that
function.

af4f136056c9 ("security: move LSM xattrnames to xattr.h") moved the
XATTR_CAPS_SUFFIX define from capability.h to xattr.h. This makes sense
except it was previously exports to userspace but xattr.h does not export
it to userspace. This patch exports these headers to userspace to fix the
ABI regression.
There is some slight possibility that this will cause problems in other
applications which used these #defines differently (wrongly) and I could
JUST export the capabilities xattr name that we broke. Does anyonehave an
idea how exposing these headers could cause a problem?
Below is what is being exposed to userspace, included here since it isn't
clear exactly what is going to be made available from the patch.

Manually adjusting the smp_affinity for IRQ's becomes unwieldy when the
cpu count is large.
Setting smp affinity to cpus 256 to 263 would be:
echo 000000ff,00000000,00000000,00000000,00000000,00000000,00000000,00000000 > smp_affinity
instead of:
echo 256-263 > smp_affinity_list
Think about what it looks like for cpus around say, 4088 to 4095.
We already have many alternate "list" interfaces:
/sys/devices/system/cpu/cpuX/indexY/shared_cpu_list
/sys/devices/system/cpu/cpuX/topology/thread_siblings_list
/sys/devices/system/cpu/cpuX/topology/core_siblings_list
/sys/devices/system/node/nodeX/cpulist
/sys/devices/pci***/***/local_cpulist
Add a companion interface, smp_affinity_list to use cpu lists instead of
cpu maps. This conforms to other companion interfaces where both a map
and a list interface exists.
This required adding a bitmap_parselist_user() function in a manner
similar to the bitmap_parse_user() function.

Apps are increasingly using more than 1024 file descriptors. See
discussion in several distro bug trackers, e.g. BugLink:
http://bugs.launchpad.net/bugs/663090
https://issues.rpath.com/browse/RPL-2054
You don't want to raise the default soft limit, since that might break
apps that use select(), but it's safe to raise the default hard limit;
that way, apps that know they need lots of file descriptors can raise
their soft limit without needing root, and without user intervention.
Ubuntu is doing this with a kernel change because they have a policy of
not changing kernel defaults in userland.
While 4096 might not be enough for *all* apps, it seems to be plenty for
the apps I've seen lately that are unhappy with 1024.

The copy_to_user_page() function is supposed to flush the icache on the
memory that was written, but the current asm-generic version lacks that
logic. While normally it isn't a big deal as the asm-generic version of
icache flushing is a stub, it is a deal for ports that want to use the
asm-generic version as a baseline and then overlay its own specific parts
(like icache flushing).
