Pull writeback fixes from Fengguang Wu:
"Three trivial writeback fixes"
* 'writeback-for-next' of git://git.kernel.org/pub/scm/linux/kernel/git/wfg/linux:
CPU hotplug, writeback: Don't call writeback_set_ratelimit() too often during hotplug
writeback: correct comment for move_expired_inodes()
backing-dev: use kstrto* in preference to simple_strtoul

during hotplug
The CPU hotplug callback related to writeback calls writeback_set_ratelimit()
during every state change in the hotplug sequence. This is unnecessary
since num_online_cpus() changes only once during the entire hotplug operation.
So invoke the function only once per hotplug, thereby avoiding the
unnecessary repetition of those costly calculations.

The function scans @delaying_queue and stops at the first inode
whose dirtied_when is after *work->older_than_this. So the expired
ones being moved are those before *work->older_than_this. Correct
the comment here.

- initialize ncurses only once in menuconfig
- be able to jump to a search result in menuconfig

* 'kconfig' of git://git.kernel.org/pub/scm/linux/kernel/git/mmarek/kbuild:
kconfig: replace 'oldnoconfig' with 'olddefconfig', and keep the old name as an alias
menuconfig: Assign jump keys per-page instead of globally
menuconfig: Do not open code textbox scroll up/down
menuconfig: Add jump keys to search results
menuconfig: Extend dialog_textbox so that it can return to a scrolled position
menuconfig: Extend dialog_textbox so that it can exit on arbitrary keypresses
menuconfig: Remove superfluous conditionnal

As 67d34a6a391369269a2e5dba8a5f42cc4cd50231 said, 'oldnoconfig' doesn't
set new symbols to 'n', but instead sets it to their default values.
So, this patch replaces 'oldnoconfig' with 'olddefconfig', stop making
people confused, and keep the old name 'oldnoconfig' as an alias,
because people already are dependent on its behavior with the
counter-intuitive name.

For large kernel configurations (like a distribution kernel)
targz-pkg takes a quite long time to just do the compression.
I clocked it at 15+mins for a SUSE kernel like config on a fast
system. And tarxz and bzip2 are even slower.
The main reason is that the script that is doing the taring sets
the highest compression level (-9). When I change it to just
use the defaults the gzip time for the same kernel goes down
to ~3 mins. I haven't tested xz and bzip, but I expect those
to be much faster too.
I'm not willing to wait that long for a small compression
gain. So just change the script to use the defaults.

This error may happen when the user's id or path includes .ko string.
For example, user's id is xxx.ko and building test.ko module,
the test.mod file lists ko name and all object files.
/home/xxx.ko/kernel_dev/device/drivers/test.ko
/home/xxx.ko/kernel_dev/device/drivers/test_main.o
/home/xxx.ko/kernel_dev/device/drivers/test_io.o ...
Current Makefile.modpost and Makefile.modinst find and list up not
only test.ko but also other object files.
because all of object file's path includes .ko string.
This is a patch to fix it.

This is a respin of an older patch sent by Sam Ravnborg:
http://www.gossamer-threads.com/lists/linux/kernel/1530602
This patch removes the annoying warning:
Makefile:708: "WARNING: Appending $KCFLAGS (-Wno-sign-compare) from command
line to kernel $CFLAGS"
which is printed every time I use KCFLAFS. The commit which introduced the
warning:
69ee0b3 kbuild: do not pick up CFLAGS from the environment
tells about the problems when people have CFLAGS in their environment,
then switches to KCFLAFS which should be enough to solve the issue, but
it anyway introduces a warning. Drop this warning.

Omapdss driver changes for the 3.7 merge window.
Notable changes:
* Basic writeback support for DISPC level. Writeback is not yet usable, though,
as we need higher level code to actually expose the writeback feature to
userspace.
* Rewriting the omapdss output drivers. We're trying to remove the hard links
between the omapdss and the panels, and this rewrite work moves us closer to
that goal.
* Cleanup and restructuring patches that have been made while working on device
tree support for omapdss. Device tree support is still some way ahead, but
these patches are good cleanups in themselves.
* Basic OMAP5 DSS support for DPI and DSI outputs.
* Workaround for the problem that GFX overlay's fifo is too small for high
resolution scenarios, causing underflows.
* Cleanups that remove dependencies to omap platform code.

Writeback pipeline receives RGB data from one of the overlays or one of the
overlay managers. If the target color mode is YUV422 or NV12, we need to convert
the RGB pixels to YUV. The scaler in WB then converts it to the target color
mode.
Hence, the color conversion coefficients that need to be programmed are the ones
which convert a RGB24 pixel to YUV444. Program these coefficients for writeback
pipeline.
Rearrange the code a bit to configure different coefficients for overlays and
writeback.

Add functions to enable writeback, and set/check state of GO bit. These bits are
identical in behaviour with the corresponding overlay manager bits. Configure
them in a similar way to mgr_enable() and mgr_go_* functions. Add a helper to
get the FRAMEDONE irq corresponding to writeback.

Extend the DISPC fifo functions to also configure the writeback FIFO thresholds.
The most optimal configuration for writeback is to push out data to the
interconnect the moment writeback pushes enough pixels in the FIFO to form a
burst. This reduces the chance of writeback overflowing it's FIFO.

Configure some of the writeback specific parameters in dispc_wb_setup(). The
writeback parameters configured are:
truncation: This needs to be set if the color depth input to writeback is more
than the color depth of the color mode we want to store in memory.
writeback mode: This configures whether we want to use writeback in mem to mem
or capture mode. This information will be directly passed by APPLY later.

Create struct omap_dss_writeback_info, this is similar to omap_overlay_info,
the major difference is that there is no parameter which describes the input
size to writeback, this is because this is always fixed, and decided by the
connected overlay or overlay manager. One more difference is that screen_width
is renamed to buf_width, to give the value of stride the writeback buffer has.
Call dispc_ovl_setup_common() through dispc_wb_setup() to configure overlay-like
parameters. The parameters in dispc_ovl_setup_common() which do not hold for
writeback are filled passed as zeroes or false, the code takes care of not
configuring them as they won't possess the needed overlay caps.

Writeback can take input from either one of the overlays, or one of the overlay
managers. Add an enum which represents the channel_in for writeback, and maps
to the register field programming.
Add a function to configure channel in for writeback. This will be used later in
APPLY.

The bit YUVCHROMARESAMPLING isn't there for writeback in DISPC_WB_ATTRIBUTES2.
It isn't there because we don't upsample chroma like for video pipelines, we
downsample chroma in writeback to get YUV422 or NV12 formats from the YUV444
input.
Ignore this bit in dispc_ovl_set_scaling_uv() if the plane is OMAP_DSS_WB.

When converting YUYV444 content to YUV422 or NV12 formats through writeback
pipeline, the scaler needs to downscale the chroma plane. Ensure that chroma
is downscaled when the pipeline is writeback.

Writeback uses the WB_PICTURE_SIZE register to define the size of the content
written to memory, this is the output of the scaler. It uses the WB_SIZE
register to define the size of the content coming from the overlay/manager to
which it is connected, this is the input to the scaler. This naming is different
as compared to overlays.
Add checks for writeback in dispc_ovl_set_input_size() and
dispc_ovl_set_output_size() to write to the correct registers.

Since writeback has many overlay like properties, and most of it's registers are
similar to that of overlays, it's possible to reuse most of the overlay related
DISPC code for writeback when considering it as a plane. Writeback was added as
a plane in the omap_plane field as OMAP_DSS_WB.
Add the writeback register offsets in dispc.h, add minimal WB plane related info
needed in dss_features. Add a function which returns the number of writeback
pipelines an OMAP version has.

In the function dispc_plane_set_scaling_uv(), create a parameter which tells if
we want to upscale or downscale the chroma plane.
Downscaling of chroma is required by writeback pipeline for converting the input
YUV444 color format to YUV422 or NV12.

The scalers of overlays and writeback do not have any constraints on downscale
ratio when operating in memory to memory mode.
This is because in memory to memory mode, we aren't connected to a display which
needs data output at the rate of pixel clock. The scalers can perform as much
downscaling as needed, the rate at which the scaler outputs is adjusted
accordingly.
Relax constraints related to downscaling based on whether the input overlays are
connected to writeback in memory to memory mode. We pass a mem_to_mem boolean
parameter to dispc_ovl_setup() from APPLY. This is currently set to false, this
will later be configured to the correct value based on whether the overlay is
connected to writeback or not. Do the same later for writeback when writeback is
configured.
In the scaling calculation code, we calculate the minimum amount of core clock we
need to achieve the required downscaling. If we are in memory to memory mode, we
set this to a very small value(1 in this case), this value would always be
lesser than the actual DISPC core clock value, and hence the scaling checks
would succeed.
We take care that pixel clock isn't calculated for writeback and the overlays
connected to it when in memory to memory mode. A pixel clock in such cases
doesn't make sense.

dispc_ovl_setup_common() is to be used by both overlays and writeback. We pass
channel out to figure out what manager the overlay is connected to, to determine
the pixel clock rate. This is used to decide the scaling limitations for that
overlay.
writeback doesn't have a channel out, it has a channel in field which tells
where writeback gets its input from. These are 2 different fields, and this
prevents us reusing the overlay configuration code for writeback.
To overcome this, we now pass omap_plane to overlay related functions rather
than passing channel out. We create helper functions which can derive pclk/lclk
from the omap_plane id.

Add position and replication as overlay caps, and pass overlay caps as an
argument to the corresponding functions. Adding position and replication to
overlay caps seems a bit unnecessary, but it allows us to use the
corresponding functions for writeback too.
These caps will be set for all overlays, but not for writeback. This is done
so writeback can reuse dispc_ovl_setup() to the maximum.

Currently, the functions below take the omap_plane parameter and derive the
overlay caps within them. Pass the overlay caps as a parameter to the function
to allow these to be used by writeback too.
- dispc_ovl_set_zorder()
- dispc_ovl_set_pre_mult_alpha()
- dispc_ovl_setup_global_alpha()
- dispc_ovl_calc_scaling()
- dispc_ovl_setup()
These functions will be used for writeback later, and the caps will help in
deciding if they are to be used for writeback or not. This allows reuse of
overlay caps for writeback.
Using omap_overlay_caps for writeback seems a bit incorrect, but caps is
something already in use by users of OMAPDSS(omapfb/omap_vout), so we use
overlay caps for overlay like features of writeback too.

output sizes
The DISPC pipeline register names in the TRM for setting the buffer size and
the output size are a bit misleading, for example, there are different register
names for setting the buffer size for VID and GFX pipes. Things get more
confusing when considering writeback pipeline.
Rename the functions so that they tell whether they are configuring the input
to the scalar or the output. These will be extended later to support writeback
registers.
