"clk: divider: fix rate calculation for fractional rates" patch (and
similar for TI specific divider) fixes the clk-divider's rounding. This
patch updates the DSS driver to round the rates accordingly.
This fixes the DSS's warnings about clock rate mismatch, and also fixes
the wrong fclk rate being set.

perf stat did initialize the stats structure used to compute
stddev etc. incorrectly. It merely zeroes it. But one member
(min) needs to be set to a non zero value. This causes min
to be not computed at all. Call init_stats() correctly.
It doesn't matter for stat currently because it doesn't use
min, but it's still better to do it correctly.
The other users of statistics are already correct.

As Namhyung reported(https://lkml.org/lkml/2014/4/1/89),
current perf-probe -L option doesn't handle errors in line-range
searching correctly. It causes a SEGV if an error occured in the
line-range searching.
----
$ perf probe -x ./perf -v -L map__load
Open Debuginfo file: /home/namhyung/project/linux/tools/perf/perf

New line range: 153 to 2147483647

Segmentation fault (core dumped)
----
This is because line_range_inline_cb() ignores errors
from find_line_range_by_line() which means that lr->path is
already freed on the error path in find_line_range_by_line().
As a result, get_real_path() accesses the lr->path and it
causes a NULL pointer exception.
This fixes line_range_inline_cb() to handle the error correctly,
and report it to the caller.
Anyway, this just fixes a possible SEGV bug, Namhyung's patch
is also required.

At the moment the omap_crtc_pre_apply() handles the enabling, disabling
and configuring of encoders and panels separately from the CRTC (i.e.
the overlay manager).
However, this doesn't work correctly. The encoder driver has to be in
control of its video input (i.e. the crtc) for correct operation.
This problem causes bugs with (at least) HDMI: the HDMI encoder supplies
pixel clock for DISPC, and DISPC supplies video stream for HDMI. The
current code first enables the HDMI encoder, and CRTC after that.
However, the encoder expects the video stream to start during the
encoder's enable, and if it doesn't, there will be sync lost errors.
The encoder enables its video source by calling src->enable(), and this
call goes to omapdrm (omap_crtc_enable), but omapdrm doesn't do anything
in that function. Similarly for disable, which goes to
omap_crtc_disable().
This patch moves the code to setup and enable/disable the crtc to
omap_crtc_enable. and omap_crtc_disable().

At module unload, omap_fbdev_free() gets called which releases the
framebuffers. However, the framebuffers are still used by crtcs, and
will be released only later at vsync. The driver doesn't wait for this,
and goes on to release the rest of the resources, which often
causes a crash.
This patchs adds a omap_crtc_flush() function which waits until the crtc
has finished with its apply queue and page flips.
The function utilizes a simple polling while-loop, as the performance is
not an issue here.

At the moment it's quite easy to get the following errors when the HDMI
output is enabled or disabled:
[drm:omap_crtc_error_irq] *ERROR* tv: errors: 00008000
The reason for the errors is that the omapdrm driver doesn't properly
handle the sync-lost irqs that happen when enabling the DIGIT crtc,
which is used for HDMI and analog TV. The driver does disable the
sync-lost irq properly, but it fails to wait until the output has been
fully enabled (i.e. the first vsync), so the sync-lost errors are still
seen occasionally.
This patch makes the omapdrm act the same way as the omapfb does:
- When enabling a display, we'll wait for the first vsync.
- When disabling a display, we'll wait for framedone if available, or
odd and even vsyncs.
These changes make sure the output is fully enabled or disabled at the
end of the function.

nft_cmp_fast is used for equality comparisions of size <= 4. For
comparisions of size < 4 byte a mask is calculated that is applied to
both the data from userspace (during initialization) and the register
value (during runtime). Both values are stored using (in effect) memcpy
to a memory area that is then interpreted as u32 by nft_cmp_fast.
This works fine on little endian since smaller types have the same base
address, however on big endian this is not true and the smaller types
are interpreted as a big number with trailing zero bytes.
The mask therefore must not include the lower bytes, but the higher bytes
on big endian. Add a helper function that does a cpu_to_le32 to switch
the bytes on big endian. Since we're dealing with a mask of just consequitive
bits, this works out fine.

size. This doesn't take into account the fact that we may have
already made successful writes to the same page (in the case of block
size < page size) and hence we can truncate the page cache away from
blocks with valid data in them. If these blocks are delayed
allocation blocks, we now have a mismatch between the page cache and
the extent tree, and this will trigger - at minimum - a delayed
block count mismatch assert when the inode is evicted from the cache.
We can also trip over it when block mapping for direct IO - this is
the most common symptom seen from fsx and fsstress when run from
xfstests.

When a write fails, if we don't clear the delalloc flags from the
buffers over the failed range, they can persist beyond EOF and cause
problems. writeback will see the pages in the page cache, see they
are dirty and continually retry the write, assuming that the page
beyond EOF is just racing with a truncate. The page will eventually
be released due to some other operation (e.g. direct IO), and it
will not pass through invalidation because it is dirty. Hence it
will be released with buffer_delay set on it, and trigger warnings
in xfs_vm_releasepage() and assert fail in xfs_file_aio_write_direct
because invalidation failed and we didn't write the corect amount.
This causes failures on block size < page size filesystems in fsx
and fsstress workloads run by xfstests.
Fix it by completely trashing any state on the buffer that could be
used to imply that it contains valid data when the delalloc range
over the buffer is punched out during the failed write handling.

Since there are SD-card support in u300, it's reasonable to
support partitions for block devices as default.
While updating the defconfig, we rebase it towards Kconfig changes.

There are both (e)MMC/SD-card support in ux500, thus it's reasonable to
support partitions for block devices as default.

Have the KB(),MB(),GB() macros produce unsigned longs to avoid
unintended sign extension issues with the gen2 memory size
detection.
What happens is first the uint8_t returned by
read_pci_config_byte() gets promoted to an int which gets
multiplied by another int from the MB() macro, and finally the
result gets sign extended to size_t.
Although this shouldn't be a problem in practice as all affected
gen2 platforms are 32bit AFAIK, so size_t will be 32 bits.

Running:
make O=dir x86_64_defconfig
make O=dir kvmconfig
the second command dirties the source tree with file ".config",
symlink "source" and objects in folder "scripts".
Fixed by using properly prefixed paths in the arch Makefile.
