2016-03-09drm/radeon: disable runtime pm on PX laptops without dGPU power controlAlex Deucher
Some PX laptops don't provide an ACPI method to control dGPU power. On those systems, the driver is responsible for handling the dGPU power state. Disable runtime PM on them until support for this is implemented.

2016-03-09tracing: Fix check for cpu online when event is disabledSteven Rostedt (Red Hat)
Commit f37755490fe9b ("tracepoints: Do not trace when cpu is offline") added a check to make sure that tracepoints only get called when the cpu is online, as it uses rcu_read_lock_sched() for protection. Commit 3a630178fd5f3 ("tracing: generate RCU warnings even when tracepoints are disabled") added lockdep checks (including rcu checks) for events that are not enabled to catch possible RCU issues that would only be triggered if a trace event was enabled. Commit f37755490fe9b only stopped the warnings when the trace event was enabled but did not prevent warnings if the trace event was called when disabled. To fix this, the cpu online check is moved to where the condition is added to the trace event. This will place the cpu online check in all places that it may be used now and in the future.

2016-03-09arm64: hugetlb: partial revert of 66b3923a1a0fWill Deacon
Commit 66b3923a1a0f ("arm64: hugetlb: add support for PTE contiguous bit") introduced support for huge pages using the contiguous bit in the PTE as opposed to block mappings, which may be slightly unwieldy (512M) in 64k page configurations. Unfortunately, this support has resulted in some late regressions when running the libhugetlbfs test suite with 64k pages and CONFIG_DEBUG_VM as a result of a BUG: | readback (2M: 64): ------------[ cut here ]------------ | kernel BUG at fs/hugetlbfs/inode.c:446! | Internal error: Oops - BUG: 0 [#1] SMP | Modules linked in: | CPU: 7 PID: 1448 Comm: readback Not tainted 4.5.0-rc7 #148 | Hardware name: linux,dummy-virt (DT) | task: fffffe0040964b00 ti: fffffe00c2668000 task.ti: fffffe00c2668000 | PC is at remove_inode_hugepages+0x44c/0x480 | LR is at remove_inode_hugepages+0x264/0x480 Rather than revert the entire patch, simply avoid advertising the contiguous huge page sizes for now while people are actively working on a fix.

2016-03-09arm64: account for sparsemem section alignment when choosing vmemmap offsetArd Biesheuvel
Commit dfd55ad85e4a ("arm64: vmemmap: use virtual projection of linear region") fixed an issue where the struct page array would overflow into the adjacent virtual memory region if system RAM was placed so high up in physical memory that its addresses were not representable in the build time configured virtual address size. However, the fix failed to take into account that the vmemmap region needs to be relatively aligned with respect to the sparsemem section size, so that a sequence of page structs corresponding with a sparsemem section in the linear region appears naturally aligned in the vmemmap region. So round up vmemmap to sparsemem section size. Since this essentially moves the projection of the linear region up in memory, also revert the reduction of the size of the vmemmap region.

2016-03-09kvm: cap halt polling at exactly halt_poll_nsDavid Matlack
When growing halt-polling, there is no check that the poll time exceeds the limit. It's possible for vcpu->halt_poll_ns grow once past halt_poll_ns, and stay there until a halt which takes longer than vcpu->halt_poll_ns. For example, booting a Linux guest with halt_poll_ns=11000: ... kvm:kvm_halt_poll_ns: vcpu 0: halt_poll_ns 0 (shrink 10000) ... kvm:kvm_halt_poll_ns: vcpu 0: halt_poll_ns 10000 (grow 0) ... kvm:kvm_halt_poll_ns: vcpu 0: halt_poll_ns 20000 (grow 10000) Signed-off-by: David Matlack <dmatlack@google.com> Fixes: aca6ff29c4063a8d467cdee241e6b3bf7dc4a171 Cc: stable@vger.kernel.org Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>

Anyway, this is a collection of lots of small fixes that slipped from the previous pull request. All fixes are about ASoC, and the majority of changes are corrections of the wrong access types in ALSA ctl enum items. They are mostly harmless on 32bit architectures, but actually buggy on 64bit. So we addressed all these now in a shot. The rest are various small ASoC driver fixes. Among them, only two changes have been done to ASoC core, and both of them are trivial.

2016-03-08drm/amdgpu: Switch to drm_vblank_on/off (v2)Daniel Vetter
Equivalent change to the radeon driver. Note that with radeon this caught a bug in the dri3 DDX implementation, which asked for vblank interrupts when the pipe is off. That bug needs to be fixed before we can merge this patch (if amdgpu is affected too). Michel discovered this one. v2: agd: switch dce8 as well.

2016-03-08drm/radeon: Switch to drm_vblank_on/offDaniel Vetter
These should be functionally equivalent to the older per/post modeset functions, except that they block out drm_vblank_get right away. There's only the clock adjusting code (outside of pageflips) in readone which uses drm_vblank_get. But that code doesn't synchronize against concurrent modesets and instead handles any such races by waiting for the right vblank to arrive with a short timetout. The longer-term plan here is to switch all kms drivers to drm_vblank_on/off so that common code like pending event cleanup can be done there, while drm_vblank_pre/post_modeset will be purely drm internal for the old UMS ioctl. Note that with this patch Michel uncovered a bug in the dri3 implementation of the DDX (it does vblank waits when the pipe is off), which had to be fixed first.
