staging: comedi: amplc_dio200: dio200_common_attach() return 0

Change the successful return value of `dio200_common_attach()` from 1 to
0.  This is propagated as the return value from the driver's "attach"
(`dio200_attach()`) or "auto_attach" (`dio200_auto_attach()`) handler.
Any non-negative value will do, but 0 is more conventional than 1.

staging: comedi: amplc_dio200: embed board layout in board structure

The amplc_dio200 driver supports both ISA and PCI boards, some of which
are quite similar.  The driver takes advantage of this by defining a
"board layout" structure `struct dio200_layout` along with an array of
this structure `dio200_layouts[]` and an enumerated type for the indices
into this array `enum dio200_layout_idx`.  The main board information
structure `struct dio200_board` contains a `layout` member holding an
enumerated index into the array of layouts and the enumerated layout
values are used to designate the indices in the initializer of
`dio200_layouts[]`.

We would like to split the ISA and PCI support into separate driver
modules and having the shared layouts makes this slightly awkward as the
enumerated values are condionally present depending on whether the
driver is configured to support ISA, PCI, or both.

Embed the `struct dio200_layout` into the main board information
structure `struct dio200_board` to make things simpler, discarding
`dio200_layouts[]` and the `enum dio200_layout_idx` in the process.
Only two of the layouts were used by more than one board anyway (each of
which was used by one ISA and one PCI board).

While we're at it, change the `has_int_sce`, `has_clk_gat_sce` and
`has_enhancements` members of `struct dio200_layout` to `bool:1`
bit-fields to save a few bytes.

staging: comedi: amplc_dio200: Simplify PCI board look-up

Set the `driver_data` member of each element (apart from the sentinel)
of our PCI device table `dio200_pci_table[]` to the index of the
corresponding element of our private PCI board details
`dio200_pci_boards[]`.  This index appears in the context parameter of
our auto_attach routine `dio200_auto_attach()`.  In this function,
nename the parameter to `context_model` and use it to set
`dev->board_ptr` to point to an element of `dio200_pci_boards[] directly
by index instead of calling `dio200_find_pci_board()` to search for the
element whose `devid` member matches the PCI device ID.

Remove `dio200_find_pci_board()` and the `devid` member of `struct
dio200_board`.  Also remove the `model` member of `struct dio200_board`
and the `enum dio200_model` type as we can do without them.  The only
function that uses the `model` member is `dio200_auto_attach()`, so use
the `context_model` parameter instead.

Define the enumerated value for each PCI board in new type `enum
dio200_pci_model` which replaces `enum dio200_model` minus the
enumerated values for the ISA boards (so the numeric values for the PCI
boards have changed).  Use these enumerated values to designate the
initializer for each element of `dio200_pci_boards[]`.

staging: comedi: amplc_dio200: don't check bus type in attach

Since the legacy attach routine `dio200_attach()` is only called for board
names matching an entry in our array of ISA boards
`dio200_isa_boards[]`, and it is reasonable to expect all elements of
`dio200_isa_boards[]` to have their `bustype` member initialized
correctly to `isa_bustype`, don't bother checking the bus type in
`dio200_attach()`.  Add `if (!DO_ISA) return -EINVAL` to optimize out
the remainder of the function if `CONFIG_COMEDI_AMPLC_DIO200_ISA` is not
defined.

Similarly, don't bother checking the bus type in

(`dio200_isa_boards[]`).  The driver doesn't allow manual configuration

Merge tag 'iio-for-3.10a' of git://git./linux/kernel/git/jic23/iio into staging-next

Jonathan writes:

First set of IIO new drivers and cleanup for the 3.10 cycle.

New stuff

1) Add OF support for specifying mappings between iio devices and their
   in kernel consumers.
2) Driver for AD7923 (extra functionality and support for ad7904, ad7914 and
   ad7924 added later in series)
3) Driver for Exynos adc (dt suppor for phy added later in series).
4) Make iio_push_event save IRQ context - necessary if it is to be used
   within an interrupt handler.  Users of this functionality to follow.
5) For iio use the device tree node name to provide the hwmon name attribute
   if available.

Removal and moves out of staging

1) Drop the adt7410 driver from IIO now that there is a hmwon driver with
   equivalent support. This device is very much targeted at hardware
   monitoring so hwmon is a more appropriate host for the driver.
2) Move iio_hwmon driver to drivers/hwmon.

Cleanups

1) Minor cleanup in ST common library.
2) Large set of patches to break the info_mask element which previously used
odd and even bits to specify if a channel attribute was either shared across
similar channels or specific to only one.  Now we have two bitmaps, one for
those parameters that are specific to this channel and one for those shared
by all channels with the same type as this one.  This has no effect on the
userspace abi. It simplifies the core code and provides more space for new
channel parameters. It has been on the todo list for a long time!

Conflicts:
drivers/iio/dac/ad5064.c

hwmon: Move the IIO client driver for hwmon out of staging

This driver uses channel maps, defined either through device tree
or platform data, to create a hwmon driver which acts as a client
for the underlying IIO device channels.  Thus a general purpose
IIO adc driver can be used to provide hardware monitoring using a subset
of its channels.

 The only non move changes here concern the description and changes to the
 dependencies to IIO explicit and hwmon implicit.

 I'm proposing moving this into hwmon on the basis of placing drivers
 based on what they provide rather than what their underlying hardware
 is.

So far, all instances of iio_hwmon set their hwmon name attribute

perf,x86: fix wrmsr_on_cpu() warning on suspend/resume

Commit 1d9d8639c063 ("perf,x86: fix kernel crash with PEBS/BTS after
suspend/resume") fixed a crash when doing PEBS performance profiling
after resuming, but in using init_debug_store_on_cpu() to restore the
DS_AREA mtrr it also resulted in a new WARN_ON() triggering.

init_debug_store_on_cpu() uses "wrmsr_on_cpu()", which in turn uses CPU
cross-calls to do the MSR update.  Which is not really valid at the
early resume stage, and the warning is quite reasonable.  Now, it all
happens to _work_, for the simple reason that smp_call_function_single()
ends up just doing the call directly on the CPU when the CPU number
matches, but we really should just do the wrmsr() directly instead.

This duplicates the wrmsr() logic, but hopefully we can just remove the
wrmsr_on_cpu() version eventually.

iio:ad7923: Implement scale reporting

The driver already claims to support scale reporting in its channel spec, but
doesn't actually implement this yet. This patch uses the regulator API to get
the reference voltage and calculates the scale based on that. The patch also
moves the global configuration bits into a field in the ad7923_state struct,
since depending on the RANGE bit, the range goes either from 0 to VREF or from 0
to 2 * VREF. So we need to know the setting of the RANGE bit when calculating
