2014-05-23drm: Add 800x600 (SVGA) screen resolution to the built-in EDIDsfeatures/edid-svgaDaniel Thompson
The 800x600 (SVGA) screen resolution was lacking in the set of built-in selectable EDID screen resolutions that can be used to repair misbehaving monitor firmware. This patch adds the related data set and expands the documentation. Note that the SVGA bit occupies a different byte to all the existing users of the established timing bits forcing a rework of the ESTABLISHED_TIMINGS_BITS macro. Tested new EDID on an aged (and misbehaving) industrial LCD panel; existing EDIDs still pass edid-decode's checksum checks.

Two ACPICA regression fixes (one recent and one for a 3.14 commit), a fix for an ACPI-related regression in TPM (introduced in 3.14), a revert of the ACPI AC driver conversion in 3.13 that went wrong for an unknown reason, two reverts of commits that attempted to remove an old user space interface in /proc and broke some utilities, in 3.13 too, a fix for a CPU hotplug bug in the ACPI processor driver (stable material), two (stable candidate) fixes for intel_pstate and a few new blacklist entries, mostly for systems that shipped with Windows 8. Specifics: - ACPICA fix for a stale pointer access introduced by a recent commit in the XSDT validation code from Lv Zheng. - ACPICA fix for the default value of the command line switch to favor 32-bit FADT addresses (in case there's a conflict between a 64-bit and a 32-bit address). The previous default was that the 32-bit version would take precedence and we tried to change it to the other way around and it didn't work. From Lv Zheng. - A TPM commit related to ACPI _DSM in 3.14 caused the driver to refuse to load if a specific _DSM was missing and that broke resume from system suspend on Chromebooks that require the TPM hardware to be restored to a working state during resume by the OS. Restore the old behavior to load the driver if the _DSM in question is not present, but prevent it from using the feature the _DSM is for. - ACPI AC driver conversion in 3.13 broke thermal management on at least one machine and has to be reverted. From Guenter Roeck. - Two reverts of 3.13 commits that attempted to remove the old ACPI battery interface in /proc, but turned out to break some utilities still using that interface. From Lan Tianyu. - ACPI processor driver fix to prevent acpi_processor_add() from modifying the CPU device's .offline field which leads to breakage if the initial online of the CPU fails. From Igor Mammedov. - Two intel_pstate fixes, one to take a BayTrail documentation update into account and one to avoid forcing the maximum P-state on init which causes CPU PM trouble on systems with P-states coordination when one of the CPU cores is initialized after an offline/online cycle triggered by user space. Both stable candidates, from Dirk Brandewie. - Fix for the ACPI video DMI blacklist entry for Dell Inspiron 7520 from Aaron Lu. - Two new ACPI video blacklist entries for machines shipping with Win8 that need to use native backlight so that it can be controlled in a usual way (which doesn't work otherwise due bugs in the ACPI tables) from Hans de Goede. - Two ACPI _OSI quirks for systems that need them to work correctly with Linux from Edward Lin and Hans de Goede" * tag 'pm+acpi-3.15-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: ACPI / video: Revert native brightness quirk for ThinkPad T530 intel_pstate: remove setting P state to MAX on init ACPICA: Tables: Restore old behavor to favor 32-bit FADT addresses.

2014-05-20sysfs: make sure read buffer is zeroedTejun Heo
13c589d5b0ac ("sysfs: use seq_file when reading regular files") switched sysfs from custom read implementation to seq_file to enable later transition to kernfs. After the change, the buffer passed to ->show() is acquired through seq_get_buf(); unfortunately, this introduces a subtle behavior change. Before the commit, the buffer passed to ->show() was always zero as it was allocated using get_zeroed_page(). Because seq_file doesn't clear buffers on allocation and neither does seq_get_buf(), after the commit, depending on the behavior of ->show(), we may end up exposing uninitialized data to userland thus possibly altering userland visible behavior and leaking information. Fix it by explicitly clearing the buffer.

2014-05-19ahci: imx: PLL clock needs 100us to settle downShawn Guo
The commit e783c51 (ahci: imx: software workaround for phy reset issue in resume) calls imx_sata_phy_reset() to reset phy immediately after SATA MPLL is enabled. It seems working fine mostly, but fails in some case as below. ... ahci-imx 2200000.sata: failed to reset phy: -110 ahci-imx: probe of 2200000.sata failed with error -110 After talking to the designer, we learnt that when enabling i.MX6Q SATA MPLL, we need to wait 100us for it to settle down for safety.

2014-05-17target: fix memory leak on XCOPYMikulas Patocka
On each processed XCOPY command, two "kmalloc-512" memory objects are leaked. These represent two allocations of struct xcopy_pt_cmd in target_core_xcopy.c. The reason for the memory leak is that the cmd_kref field is not initialized (thus, it is zero because the allocations were done with kzalloc). When we decrement zero kref in target_put_sess_cmd, the result is not zero, thus target_release_cmd_kref is not called. This patch fixes the bug by moving kref initialization from target_get_sess_cmd to transport_init_se_cmd (this function is called from target_core_xcopy.c, so it will correctly initialize cmd_kref). It can be easily verified that all code that calls target_get_sess_cmd also calls transport_init_se_cmd earlier, thus moving kref_init shouldn't introduce any new problems.

2014-05-15Target/iscsi,iser: Avoid accepting transport connections during stop stageSagi Grimberg
When the target is in stop stage, iSER transport initiates RDMA disconnects. The iSER initiator may wish to establish a new connection over the still existing network portal. In this case iSER transport should not accept and resume new RDMA connections. In order to learn that, iscsi_np is added with enabled flag so the iSER transport can check when deciding weather to accept and resume a new connection request. The iscsi_np is enabled after successful transport setup, and disabled before iscsi_np login threads are cleaned up.

2014-05-15Target/iser: Fix iscsit_accept_np and rdma_cm racy flowSagi Grimberg
RDMA CM and iSCSI target flows are asynchronous and completely uncorrelated. Relying on the fact that iscsi_accept_np will be called after CM connection request event and will wait for it is a mistake. When attempting to login to a few targets this flow is racy and unpredictable, but for parallel login to dozens of targets will race and hang every time. The correct synchronizing mechanism in this case is pending on a semaphore rather than a wait_for_event. We keep the pending interruptible for iscsi_np cleanup stage.

2014-05-15parisc: Improve LWS-CAS performanceJohn David Anglin
The attached change significantly improves the performance of the LWS-CAS code in syscall.S. This allows a number of packages to build (e.g., zeromq3, gtest and libxs) that previously failed because slow LWS-CAS performance under contention. In particular, interrupts taken while the lock was taken degraded performance significantly. The change does the following: 1) Disables interrupts around the CAS operation, and 2) Changes the loads and stores to use the ordered completer, "o", on PA 2.0. "o" and "ma" with a zero offset are equivalent. The latter is accepted on both PA 1.X and 2.0. The use of ordered loads and stores probably makes no difference on all existing hardware, but it seemed pedantically correct. In particular, the CAS operation must complete before LDCW lock is released. As written before, a processor could reorder the operations. I don't believe the period interrupts are disabled is long enough to significantly increase interrupt latency. For example, the TLB insert code is longer. Worst case is a memory fault in the CAS operation. Signed-off-by: John David Anglin <dave.anglin@bell.net> Cc: stable@vger.kernel.org # 3.13+ Signed-off-by: Helge Deller <deller@gmx.de>
