The RGB444 format swapped the red and blue components, fix this.
Rather than making a new BGR444 format (as I proposed initially), Jon prefers
to just fix this and return the colors in the right order. I think that makes
sense in this case.
Since the RGB444 pixel format is deprecated due to the ambiguous specification
of the alpha component we use the XRGB444 pixel format instead (specified as having
no alpha channel).

Instead of using a vector of security operations
with explicit, special case stacking of the capability
and yama hooks use lists of hooks with capability and
yama hooks included as appropriate.
The security_operations structure is no longer required.
Instead, there is a union of the function pointers that
allows all the hooks lists to use a common mechanism for
list management while retaining typing. Each module
supplies an array describing the hooks it provides instead
of a sparsely populated security_operations structure.
The description includes the element that gets put on
the hook list, avoiding the issues surrounding individual
element allocation.
The method for registering security modules is changed to
reflect the information available. The method for removing
a module, currently only used by SELinux, has also changed.
It should be generic now, however if there are potential
race conditions based on ordering of hook removal that needs
to be addressed by the calling module.
The security hooks are called from the lists and the first
failure is returned.

In order to avoid having each driver adding their own
specific DT property to specify slope and offset,
this patch adds a basic coefficient reading from
DT thermal zone node. Right now, as the thermal
framework does not support multiple sensors,
the current coefficients apply only to the only
sensor in the thermal zone.
The supported equation is a simple linear model:
slope * <sensor reading> + offset.
slope and offset are read from the coefficients
DT property. In the same way as it is described in
the DT thermal binding.
So, as of today, the thermal framework will support
only cases like:
/* hotspot = 1 * adc + 6000 */
coefficients = <1 6000>;
Signed-off-by: Eduardo Valentin <edubezval@gmail.com>
It is common to have a linear extrapolation from
the current sensor readings and the actual temperature
value. This is specially the case when the sensor
is in use to extrapolate hotspots.
This patch adds slope and offset constants for
single sensor linear extrapolation equation. Because
the same sensor can be use in different locations,
from board to board, these constants are added
as part of thermal_zone_params.
The constants are available through sysfs.
It is up to the device driver to determine
the usage of these values.

In situations where there is an uneven number of cooling devices, the
division of power among them can lead to a milliwatt being dropped on
the floor due to rounding errors. This doesn't sound like a lot, but
some devices only grant the lowest cooling device state for their
maximum power. So for instance, if the granted_power is the maximum
power and all devices are getting their maximum power, one would get
max_power - 1, making it choose cooling device state 1, instead of 0.
Round the division to make the calculation more accurate.

Serialize against find_linux_pte_or_hugepte() which does lock-less
lookup in page tables with local interrupts disabled. For huge pages it
casts pmd_t to pte_t. Since the format of pte_t is different from pmd_t
we want to prevent transit from pmd pointing to page table to pmd
pointing to huge page (and back) while interrupts are disabled. We
clear pmd to possibly replace it with page table pointer in different
code paths. So make sure we wait for the parallel
find_linux_pte_or_hugepage() to finish.
Without this patch, a find_linux_pte_or_hugepte() running in parallel to
__split_huge_zero_page_pmd() or do_huge_pmd_wp_page_fallback() or
zap_huge_pmd() can run into the above issue. With
__split_huge_zero_page_pmd() and do_huge_pmd_wp_page_fallback() we clear
the hugepage pte before inserting the pmd entry with a regular pgtable
address. Such a clear need to wait for the parallel
find_linux_pte_or_hugepte() to finish.
With zap_huge_pmd(), we can run into issues, with a hugepage pte getting
zapped due to a MADV_DONTNEED while other cpu fault it in as small
pages.

Without this fix, and with iwarp port mapping enabled, each iw_cxgb4

Merge tag 'spi-fix-v4.1-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi
Pull spi fixes from Mark Brown:
"A number of driver specific fixes (including several missing
dependencies for randconfig type cases) plus two core fixes.
One makes the setup_transfer() callback optional which unbreaks some
drivers which had been merged with it omitted due to local versions of
this patch and another ensures that we don't corrupt data by leaking
internal dummy buffers to callers, causing the callers to think they
allocated those buffers"
* tag 'spi-fix-v4.1-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi:
spi: fsl-espi: fix behaviour for full-duplex xfers
spi: fsl-spi: fix devm_ioremap_resource() error case
spi: Kconfig: Add SOC_LS1021A to SPI_FSL_DSPI dependence
spi/omap2-mcpsi: Always call spi_finalize_current_message()
spi: fsl-spi: use devm_ioremap_resource() to map parameter ram on CPM1
spi: bitbang: Make setup_transfer() callback optional
spi: check tx_buf and rx_buf in spi_unmap_msg
spi: bcm2835: change timeout of polling driver to 1s
spi: bcm2835: Add GPIOLIB dependency
Fix a few AM43xx problems: add the VPFE hwmod data, which removes some
warnings; and fix the IP block hardreset implementation.
Basic build, boot, and PM test results are here:
http://www.pwsan.com/omap/testlogs/omap-hwmod-a-for-v4.1-rc/20150508130543/
Note that I do not have an AM43xx board in the testbed, and thus
cannot test on that platform.

ARM: OMAP2+: first set of hwmod fixes for v4.1-rc
Fix a few AM43xx problems: add the VPFE hwmod data, which removes some
warnings; and fix the IP block hardreset implementation.
Basic build, boot, and PM test results are here:
http://www.pwsan.com/omap/testlogs/omap-hwmod-a-for-v4.1-rc/20150508130543/
Note that I do not have an AM43xx board in the testbed, and thus
cannot test on that platform.
With recent changes to use determine_rate, the comparison of two
clocks won't work without clk_is_match that does __clk_get_hw
on the clocks first.
As we've been unconditionally already calling clk_set_parent
already because of the bogus comparison, let's just remove the
check as suggested by Stephen Boyd <sboyd@codeaurora.org>.
