Kay Sievers noted that the ALWAYS_USE_PERSISTENT_CLOCK config,
which enables some minor compile time optimization to avoid
uncessary code in mostly the suspend/resume path could cause
problems for userland.
In particular, the dependency for RTC_HCTOSYS on
!ALWAYS_USE_PERSISTENT_CLOCK, which avoids setting the time
twice and simplifies suspend/resume, has the side effect
of causing the /sys/class/rtc/rtcN/hctosys flag to always be
zero, and this flag is commonly used by udev to setup the
/dev/rtc symlink to /dev/rtcN, which can cause pain for
older applications.
While the udev rules could use some work to be less fragile,
breaking userland should strongly be avoided. Additionally
the compile time optimizations are fairly minor, and the code
being optimized is likely to be reworked in the future, so
lets revert this change.

efx_start_datapath() asserts that we can fit 2 RX scatter buffers plus
a software structure, each appropriately aligned, into a single page.
Where L1_CACHE_BYTES == 256 and PAGE_SIZE == 4096, which is the case
on s390, this assertion fails.
The current scatter buffer size is also not a multiple of 64 or 128,
which are more common cache line sizes. If we can make both the start
and end of a scatter buffer cache-aligned, this will reduce the need
for read-modify-write operations on inter- processor links.
Fix the alignment by reducing EFX_RX_USR_BUF_SIZE to 2048 - 256 ==
1792. (We could use 2048 - L1_CACHE_BYTES, but EFX_RX_USR_BUF_SIZE
also affects user-level networking where a larger amount of
housekeeping data may be needed. Although this version of the driver
does not support user-level networking, I prefer to keep scattering
behaviour consistent with the out-of-tree version.)
This still doesn't fix the s390 build because like most architectures
it has NET_IP_ALIGN == 2. When NET_IP_ALIGN != 0 we cannot achieve
cache line alignment at either the start or end of a scatter buffer,
so there is actually no point in padding the buffers to a multiple of
the cache line size. All we need is 4-byte alignment of the network
header, so do that.
Adjust the assertions accordingly.

Platform Data is invariably populated for this driver, even when
booting with Device Tree. Thus the Device Tree probing code encased
within the first check for Platform Data will never executed, causing
the driver to fail when DT is enabled.
This patch fixes the aforementioned regression by rejigging the
probe() semantics to attempt to extract a platform ID from Device Tree
if one can not be sourced from platform data.
A pointer to GPIO platform data is always passed to the driver now, so
there's little point in checking for 'pdata' and executing the DT case if
it's not there. The difference between booting with DT and !DT is when
booting with DT, plat_id is not populated. Thus, in the DT case we have
to use a DT match table in order to find out which platform we're
executing on. So, we're changing the semantics here to only use the
match table if no plat_id is supplied though platform data.

The DMA controller in Lynxpoint is enumerated as a regular ACPI device now. To
work properly it is using the LPSS root clock as a functional clock. That's why
we have to register the clock device accordingly to the ACPI ID of the DMA
controller. The acpi_lpss.c module is responsible to do the job.
This patch also removes hardcoded name of the DMA device in clk-lpt.c and the
name of the root clock in acpi_lpss.c.

"ni_mio_common.c" holds common code included by "ni_pcimio.c",
"ni_atmio.c" and "ni_mio_cs.c", including a common initialization
function `ni_E_init()`. Amongst other things, this initializes some
counter subdevices to support comedi instructions and asynchronous
commands. However, even though it sets up the handlers to support
asynchronous commands on these subdevices, the handlers will return an
error unless the `PCIDMA` macro is defined (which is defined only in
"ni_pcimio.c"). If the `PCIDMA` macro is not defined, the comedi core
will needlessly allocate buffers to support the asynchronous commands.
Also, `s->async_dma_dir` is set to `DMA_BIDIRECTIONAL`, causing the
physical pages for the buffers to be allocated using
`dma_alloc_coherent()`.
If the comedi core cannot call `dma_alloc_coherent()` because
`CONFIG_HAS_DMA` is not defined, it will fail to allocate the buffers,
which ultimately causes `ni_E_init()` to fail.
Avoid the wastage and prevent the failure by only setting up
asynchronous command support for the counter subdevices if the `PCIDMA`
macro is defined.

The core "comedi" module and the "mite" helper module for NI PCI devices
both have calls to `dma_alloc_coherent()` and `dma_free_coherent()`.
Those functions are only available if `CONFIG_HAS_DMA` is defined.
Apart from the "mite" module, the functions are only called for comedi
drivers that set `s->async_dma_dir` (where `s` is a pointer to a `struct
comedi_subdevice`) to anything other than `DMA_NONE`.
Change local helper functions `__comedi_buf_alloc()` and
`__comedi_buf_free()` to only call `dma_alloc_coherent()` and
`dma_free_coherent()` if `CONFIG_HAS_DMA` is defined.
Change the "Kconfig" to make the following configuration options depend
on `HAS_DMA`:
`COMEDI_MITE` - builds the "mite" module.
`COMEDI_NI_6527` - selects `COMEDI_MITE`.
`COMEDI_NI_65XX` - selects `COMEDI_MITE`.
`COMEDI_NI_670X` - selects `COMEDI_MITE`.

When a comedi device is successfully attached, those subdevices that
support asynchronous commands will have had buffers allocated
successfully. It is possible to resize the buffers afterwards, but if
the resize fails the subdevice is left with no buffer
(`s->async->prealloc_buf == NULL`). Currently, this also causes any
subsequent attempts to resize the buffer to fail with an error, which
seems like a bad idea.
Remove the check in `resize_async_buffer()` that causes the resize to
fail if the subdevice currently has no buffer (presumably due to the
failure of a previous resize attempt). Callers of
`resize_async_buffer()` have already checked that the subdevice is
allowed to have a buffer.

After merging the final tree, the next-20130424 build (powerpc
allyesconfig) failed like this:
drivers/staging/comedi/drivers/ni_labpc.c: In function 'labpc_ai_cmd':
drivers/staging/comedi/drivers/ni_labpc.c:980:9: error:
implicit declaration of function 'virt_to_bus'
[-Werror=implicit-function-declaration]
The virt_to_bus() is only needed for the ISA DMA support in this driver.
On powerpc, CONFIG_COMEDI_NI_LABPC_ISA cannot be enabled due to the
depends on VIRT_TO_BUS but the PCI driver, ni_labpc_pci, can be enabled.
That driver uses the ni_labpc driver for the common support code shared
by the ISA, PCI, and PCMCIA boards.
The ISA specific support, and the optional ISA DMA support, are currently
still in the common ni_labpc driver. The ISA specific code is protected
by #if IS_ENABLED(CONFIG_COMEDI_NI_LABPC_ISA) and the ISA DMA support
is protected by #ifdef CONFIG_ISA_DMA_API. This allows the ISA support
to be enabled on architectures that support VIRT_TO_BUS and optionally
enables ISA DMA support if ISA_DMA_API is enabled.
Unfortunately, the ISA DMA code uses virt_to_bus(). This results in
the build failure for architectures that enable ISA_DMA_API but do not
have VIRT_TO_BUS.
Add a new member to the private data, dma_addr, to hold the phys_addr_t
returned by virt_to_bus() and initialize it in the ISA specific
labpc_attach().
For architectures that enable ISA_DMA_API but not VIRT_TO_BUS, this
will fix the build error. This is also safe for architectures the
enable both options but don't enable COMEDI_NI_LABPC_ISA because the
dma channel (devpriv->dma_chan) is only initialized in the ISA
specific labpc_attach().

Add code to rbd_img_parent_read_full_callback() to detect when a
clone's parent image has disappeared, and re-submit the original
write request in that case. (See the previous commit for more
reasoning about why this is appropriate.)
Rename some variables in rbd_img_obj_parent_read_full_callback()
to match the convention used in the previous patch.
