2015-12-14gpu: host1x: Add Tegra210 supportThierry Reding8-1/+768
The host1x unit found in Tegra210 SoCs is very similar to the unit in Tegra124, but it has 2 additional channels for a total of 14 channels. Signed-off-by: Thierry Reding <treding@nvidia.com>
2015-12-14gpu: host1x: Remove core driver on unregisterThierry Reding1-0/+2
When unregistering a host1x driver, make sure to unregister the core driver as well to prevent it from sticking around and oppose reloading of the driver. Signed-off-by: Thierry Reding <treding@nvidia.com>
2015-12-14gpu: host1x: Use platform_register/unregister_drivers()Thierry Reding1-14/+8
These new helpers simplify implementing multi-driver modules and properly handle failure to register one driver by unregistering all previously registered drivers. Signed-off-by: Thierry Reding <treding@nvidia.com>

[Al Viro] The bug is in being too enthusiastic about optimizing ->setattr() away - instead of "copy verbatim with metadata" + "chmod/chown/utimes" (with the former being always safe and the latter failing in case of insufficient permissions) it tries to combine these two. Note that copyup itself will have to do ->setattr() anyway; _that_ is where the elevated capabilities are right. Having these two ->setattr() (one to set verbatim copy of metadata, another to do what overlayfs ->setattr() had been asked to do in the first place) combined is where it breaks.

2015-12-05x86/signal: Fix restart_syscall number for x32 tasksDmitry V. Levin1-7/+10
When restarting a syscall with regs->ax == -ERESTART_RESTARTBLOCK, regs->ax is assigned to a restart_syscall number. For x32 tasks, this syscall number must have __X32_SYSCALL_BIT set, otherwise it will be an x86_64 syscall number instead of a valid x32 syscall number. This issue has been there since the introduction of x32. Reported-by: strace/tests/restart_syscall.test Reported-and-tested-by: Elvira Khabirova <lineprinter0@gmail.com> Signed-off-by: Dmitry V.

2015-12-05x86/mpx: Fix instruction decoder conditionDave Hansen1-3/+3
MPX decodes instructions in order to tell which bounds register was violated. Part of this decoding involves looking at the "REX prefix" which is a special instrucion prefix used to retrofit support for new registers in to old instructions. The X86_REX_*() macros are defined to return actual bit values: #define X86_REX_R(rex) ((rex) & 4) *not* boolean values. However, the MPX code was checking for them like they were booleans. This might have led to us mis-decoding the "REX prefix" and giving false information out to userspace about bounds violations. X86_REX_B() actually is bit 1, so this is really only broken for the X86_REX_X() case. Fix the conditionals up to tolerate the non-boolean values.

into drm-next A few more last minute fixes for 4.4 on top of my pull request from earlier this week. The big change here is a vblank regression fix due to commit 4dfd6486 "drm: Use vblank timestamps to guesstimate how many vblanks were missed". Beyond that, a hotplug fix and a few VM fixes. * 'drm-fixes-4.4' of git://people.freedesktop.org/~agd5f/linux: drm/amdgpu: Fixup hw vblank counter/ts for new drm_update_vblank_count() (v3) drm/radeon: Fixup hw vblank counter/ts for new drm_update_vblank_count() (v2) drm/radeon: Retry DDC probing on DVI on failure if we got an HPD interrupt drm/amdgpu: add spin lock to protect freed list in vm (v2) drm/amdgpu: partially revert "drm/amdgpu: fix VM_CONTEXT*_PAGE_TABLE_END_ADDR" v2 drm/amdgpu: take a BO reference for the user fence drm/amdgpu: take a BO reference in the display code drm/amdgpu: set snooped flags only on system addresses v2 drm/amdgpu: fix race condition in amd_sched_entity_push_job drm/amdgpu: add err check for pin userptr add blacklist for thinkpad T40p drm/amdgpu: fix VM page table reference counting drm/amdgpu: fix userptr flags check
