2015-04-07target: Add protected fabric + unprotected device supportNicholas Bellinger
This patch adds a new target_core_fabric_ops callback for allowing fabric drivers to expose a TPG attribute for signaling when a T10-PI protected fabric wants to function with an un-protected device without T10-PI. This specifically is to allow LIO to perform WRITE_STRIP + READ_INSERT operations when functioning with non T10-PI enabled devices, seperate from any available hw offloads the fabric supports. This is done using a new se_sess->sess_prot_type that is set at fabric session creation time based upon the TPG attribute. It currently cannot be changed for individual sessions after initial creation. Also, update existing target_core_sbc.c code to honor sess_prot_type when setting up cmd->prot_op + cmd->prot_type assignments.

2015-04-08x86, selftests: Add sigreturn selftestAndy Lutomirski
This is my sigreturn test, added mostly unchanged from its old home. It exercises the sigreturn(2) syscall, specifically focusing on its interactions with various IRET corner cases. It tests for correct behavior in several areas that were historically dangerously buggy. For example, it exercises espfix on kernels of both bitnesses under various conditions, and it contains testcases for several now-fixed bugs in IRET error handling. If you run it on older kernels without the fixes, your system will crash. It probably won't eat your data in the process. There is no released kernel on which the sigreturn_64 test will pass, but it passes on tip:x86/asm. I plan to switch to lib.mk for Linux 4.2. I'm not using the ksft_ helpers at all yet. I can do that later.

git://anongit.freedesktop.org/tegra/linux into drm-next drm/tegra: Changes for v4.1-rc1 Perhaps the most noteworthy change in this set is the implementation of a hardware VBLANK counter using host1x syncpoints. The SOR registers can now be dumped via debugfs, which can be useful while debugging. The IOVA address space maintained by the driver can also be dumped via debugfs. Other than than, these changes are mostly cleanup work, such as making register names more consistent or removing unused code (that was left over after the atomic mode-setting conversion). There's also a fix for eDP that makes the driver cope with firmware that already initialized the display (such as the firmware on the Tegra-based Chromebooks). * tag 'drm/tegra/for-4.1-rc1' of git://anongit.freedesktop.org/tegra/linux: drm/tegra: sor: Reset during initialization drm/tegra: gem: Return 64-bit offset for mmap(2) drm/tegra: hdmi: Name register fields consistently drm/tegra: hdmi: Resets are synchronous drm/tegra: dc: Document tegra_dc_state_setup_clock() drm/tegra: dc: Remove unused callbacks drm/tegra: dc: Remove unused function drm/tegra: dc: Use base atomic state helpers drm/atomic: Add helpers for state-subclassing drivers drm/tegra: dc: Implement hardware VBLANK counter gpu: host1x: Export host1x_syncpt_read() drm/tegra: sor: Dump registers via debugfs drm/tegra: sor: Registers are 32-bit drm/tegra: Provide debugfs file for the IOVA space drm/tegra: dc: Check for valid parent clock
