2014-07-30ARM: nomadik: fix up double inversion in DTLinus Walleij2-4/+5
The GPIO pin connected to card detect was inverted twice: once by the argument to the GPIO line itself where it was magically marked as active low by the flag GPIO_ACTIVE_LOW (0x01) in the third cell, and also marked active low AGAIN by explicitly stating "cd-inverted" (a deprecated method). After commit 78f87df2b4f8760954d7d80603d0cfcbd4759683 "mmc: mmci: Use the common mmc DT parser" this results in the line being inverted twice so it was effectively uninverted, while the old code would not have this effect, instead disregarding the flag on the GPIO line altogether, which is a bug. I admit the semantics may be unclear but inverting twice is as good a definition as any on how this should work. So fix up the buggy device tree. Use proper #includes so the DTS is clear and readable. Cc: Ulf Hansson <ulf.hansson@linaro.org> Signed-off-by: Linus Walleij <linus.walleij@linaro.org> Signed-off-by: Olof Johansson <olof@lixom.net>

2014-07-29ARM: dts: Revert enabling of twl configuration for n900Tony Lindgren1-1/+1
Commit 9188883fd66e9 (ARM: dts: Enable twl4030 off-idle configuration for selected omaps) allowed n900 to cut off core voltages during off-idle. This however caused a regression where twl regulator vaux1 was not getting enabled for the LCD panel as we are not requesting it for the panel. Turns out quite a few devices on n900 are using vaux1, and we need to either stop idling it, or add proper regulator_get calls for all users. But until we have a proper solution implemented and tested, let's just disable the twl off-idle configuration for now for n900.

2014-07-19Btrfs: fix abnormal long waiting in fsyncLiu Bo1-0/+11
xfstests generic/127 detected this problem. With commit 7fc34a62ca4434a79c68e23e70ed26111b7a4cf8, now fsync will only flush data within the passed range. This is the cause of the above problem, -- btrfs's fsync has a stage called 'sync log' which will wait for all the ordered extents it've recorded to finish. In xfstests/generic/127, with mixed operations such as truncate, fallocate, punch hole, and mapwrite, we get some pre-allocated extents, and mapwrite will mmap, and then msync. And I find that msync will wait for quite a long time (about 20s in my case), thanks to ftrace, it turns out that the previous fallocate calls 'btrfs_wait_ordered_range()' to flush dirty pages, but as the range of dirty pages may be larger than 'btrfs_wait_ordered_range()' wants, there can be some ordered extents created but not getting corresponding pages flushed, then they're left in memory until we fsync which runs into the stage 'sync log', and fsync will just wait for the system writeback thread to flush those pages and get ordered extents finished, so the latency is inevitable. This adds a flush similar to btrfs_start_ordered_extent() in btrfs_wait_logged_extents() to fix that.

2014-07-19random: check for increase of entropy_count because of signed conversionHannes Frederic Sowa1-3/+14
The expression entropy_count -= ibytes << (ENTROPY_SHIFT + 3) could actually increase entropy_count if during assignment of the unsigned expression on the RHS (mind the -=) we reduce the value modulo 2^width(int) and assign it to entropy_count. Trinity found this. [ Commit modified by tytso to add an additional safety check for a negative entropy_count -- which should never happen, and to also add an additional paranoia check to prevent overly large count values to be passed into urandom_read(). ] Reported-by: Dave Jones <davej@redhat.com> Signed-off-by: Hannes Frederic Sowa <hannes@stressinduktion.org> Signed-off-by: Theodore Ts'o <tytso@mit.edu> Cc: stable@vger.kernel.org
2014-07-18ARM: EXYNOS: Fix core ID used by platsmp and hotplug codeTomasz Figa2-19/+25
When CPU topology is specified in device tree, cpu_logical_map() does not return core ID anymore, but rather full MPIDR value. This breaks existing calculation of PMU register offsets on Exynos SoCs. This patch fixes the problem by adjusting the code to use only core ID bits of the value returned by cpu_logical_map() to allow CPU topology to be specified in device tree on Exynos SoCs.
