mfd: Add sharing for cs5535 acpi/pms cells

This enables sharing of cs5535-mfd cells via the new mfd_shared_* API.
Hooks for enable/disble of resources are added, with refcounting of
resources being automatically handled so that cs5535_mfd_res_enable/disable
are only called when necessary.

Clients of cs5535-mfd (in this case, olpc-xo1.c) are also modified to
use the mfd_shared API.  The platform drivers are also renamed to
olpc-xo1-{pms,acpi}, and resource enabling/disabling is replaced
with mfd_shared API calls.

mfd: add platform_device sharing support for mfd

This adds functions to enable platform_device sharing for mfd clients.

Each platform driver (mfd client) that wants to share an mfd_cell's
platform_device uses the mfd_shared_platform_driver_{un,}register()
functions instead of platform_driver_{un,}register().  Along with
registering the platform driver, these also register a new platform
device with the same characteristics as the original cell, but a different
name.  Given an mfd_cell with the name "foo", drivers that want to
share access to its resources can call mfd_shared_platform_driver_register
with platform drivers named (for example) "bar" and "baz".  This
will register two platform devices and drivers named "bar" and "baz"
that share the same cell as the platform device "foo".  The drivers
can then call "foo" cell's enable hooks (or mfd_shared_cell_enable)
to enable resources, and obtain platform resources as they normally
would.

This deals with platform handling only; mfd driver-specific details,
hardware handling, refcounting, etc are all dealt with separately.

mfd: Add refcounting support to mfd_cells

This provides convenience functions for sharing of cells across
multiple mfd clients.  Mfd drivers can provide enable/disable hooks
to actually tweak the hardware, and clients can call
mfd_shared_cell_{en,dis}able without having to worry about whether
or not another client happens to have enabled or disabled the
cell/hardware.

Note that this is purely optional; drivers can continue to use
the mfd_cell's enable/disable hooks for their own purposes, if
desired.

mfd-core: Unconditionally add mfd_cell to every platform_device

Previously, one would set the mfd_cell's platform_data/data_size to point
to the current mfd_cell in order to pass that information along to drivers.

This causes the current mfd_cell to always be available to drivers.  It
also adds a wrapper function for fetching the mfd cell from a platform
device, similar to what originally existed for mfd devices.

Drivers who previously used platform_data for other purposes can still
use it; the difference is that mfd_get_data() must be used to
access it (and the pdata structure is no longer allocated in
mfd_add_devices).

Note that mfd_get_data is intentionally vague (in name) about where
the data is stored; variable name changes can come later without having
to touch brazillions of drivers.

mfd: Leave acknowledgement of WM831x touchscreen IRQs to the driver

The WM831x touchscreen interrupts need acknowledgement even when using
direct signals to the CPU (which don't go through the core) so leave
the acknowledgement up to the touchscreen driver for simplicity.

bloat-o-meter: include read-only data section in report

I'm not sure why the read-only data section is excluded from the report,
it seems as relevant as the other data sections (b and d).

I've stripped the symbols starting with __mod_ as they can have their
names dynamically generated and thus comparison between binaries is not
possible.

zlib: slim down zlib_deflate() workspace when possible

Instead of always creating a huge (268K) deflate_workspace with the
maximum compression parameters (windowBits=15, memLevel=8), allow the
caller to obtain a smaller workspace by specifying smaller parameter
values.

For example, when capturing oops and panic reports to a medium with
limited capacity, such as NVRAM, compression may be the only way to
capture the whole report.  In this case, a small workspace (24K works
fine) is a win, whether you allocate the workspace when you need it (i.e.,
during an oops or panic) or at boot time.

I've verified that this patch works with all accepted values of windowBits
(positive and negative), memLevel, and compression level.

adfs: add hexadecimal filetype suffix option

ADFS (FileCore) storage complies with the RISC OS filetype specification
(12 bits of file type information is stored in the file load address,
rather than using a file extension).  The existing driver largely ignores
this information and does not present it to the end user.

It is desirable that stored filetypes be made visible to the end user to
facilitate a precise copy of data and metadata from a hard disc (or image
thereof) into a RISC OS emulator (such as RPCEmu) or to a network share
which can be accessed by real Acorn systems.

This patch implements a per-mount filetype suffix option (use -o
ftsuffix=1) to present any filetype as a ,xyz hexadecimal suffix on each
file.  This type suffix is compatible with that used by RISC OS systems
that access network servers using NFS client software and by RPCemu's host
filing system.

adfs: improve timestamp precision

ADFS (FileCore) storage complies with the RISC OS timestamp specification
(40-bit centiseconds since 01 Jan 1900 00:00:00).  It is desirable that
stored timestamp precision be maintained to facilitate a precise copy of
data and metadata from a hard disc (or image thereof) into a RISC OS
emulator (such as RPCEmu).

This patch implements a full-precision conversion from ADFS to Unix
timestamp as the existing driver, for ease of calculation with old 32-bit
compilers, uses the common trick of shifting the 40-bits representing
centiseconds around into 32-bits representing seconds thereby losing
precision.

adfs: fix E+/F+ dir size > 2048 crashing kernel

Kernel crashes in fs/adfs module when accessing directories with a large
number of objects on mounted Acorn ADFS E+/F+ format discs (or images) as
the existing code writes off the end of the fixed array of struct
buffer_head pointers.

Additionally, each directory access that didn't crash would leak a buffer
as nr_buffers was not adjusted correctly for E+/F+ discs (was always left
as one less than required).

The patch fixes this by allocating a dynamically-sized set of struct
buffer_head pointers if necessary for the E+/F+ case (many directories
still do in fact fit in 2048 bytes) and sets the correct nr_buffers so
that all buffers are released.

Addresses https://bugzilla.kernel.org/show_bug.cgi?id=26072

Tested by tar'ing the contents of my RISC PC's E+ format 20Gb HDD which

x86: allow CONFIG_ISA_DMA_API to be disabled

Not all 64-bit systems require ISA-style DMA, so allow it to be
configurable.  x86 utilizes the generic ISA DMA allocator from
kernel/dma.c, so require it only when CONFIG_ISA_DMA_API is enabled.

Disabling CONFIG_ISA_DMA_API is dependent on x86_64 since those machines
do not have ISA slots and benefit the most from disabling the option (and
on CONFIG_EXPERT as required by H.  Peter Anvin).

When disabled, this also avoids declaring claim_dma_lock(),
release_dma_lock(), request_dma(), and free_dma() since those interfaces
will no longer be provided.

sigma-firmware: loader for Analog Devices' SigmaStudio

Analog Devices' SigmaStudio can produce firmware blobs for devices with
these DSPs embedded (like some audio codecs).  Allow these device drivers
to easily parse and load them.

kstrto*: converting strings to integers done (hopefully) right

1. simple_strto*() do not contain overflow checks and crufty,
   libc way to indicate failure.
2. strict_strto*() also do not have overflow checks but the name and
   comments pretend they do.
3. Both families have only "long long" and "long" variants,
   but users want strtou8()
4. Both "simple" and "strict" prefixes are wrong:
   Simple doesn't exactly say what's so simple, strict should not exist
   because conversion should be strict by default.

The solution is to use "k" prefix and add convertors for more types.
Enter
kstrtoull()
kstrtoll()
kstrtoul()
kstrtol()
kstrtouint()
kstrtoint()

kstrtou64()
kstrtos64()
kstrtou32()
kstrtos32()
kstrtou16()
kstrtos16()
kstrtou8()
kstrtos8()

Include runtime testsuite (somewhat incomplete) as well.

strict_strto*() become deprecated, stubbed to kstrto*() and
eventually will be removed altogether.

Use kstrto*() in code today!

Note: on some archs _kstrtoul() and _kstrtol() are left in tree, even if
      they'll be unused at runtime. This is temporarily solution,
      because I don't want to hardcode list of archs where these
      functions aren't needed. Current solution with sizeof() and
      __alignof__ at least always works.
