2015-06-20drm/exynos: split exynos_crtc->dpms in enable() and disable()Gustavo Padovan
To follow more closely the new atomic API we split the dpms() helper into the enable() and disable() helper to get exactly the same semantics. Signed-off-by: Gustavo Padovan <gustavo.padovan@collabora.co.uk> Signed-off-by: Inki Dae <inki.dae@samsung.com>

2015-06-20drm/exynos: atomic dpms supportGustavo Padovan
Run dpms operations through the atomic intefaces. This basically removes the .dpms() callback from econders and crtcs and use .disable() and .enable() to turn the crtc on and off. v2: Address comments by Joonyoung: - make hdmi code call ->disable() instead of ->dpms() - do not use WARN_ON on crtc enable/disable v3: - Fix build failure after the hdmi change in v2 - Change dpms helper of ptn3460 bridge v4: - remove win_commit() call from .enable() v5: - move .atomic_check() to the atomic PageFlip patch, and transform it in .atomic_begin() Signed-off-by: Gustavo Padovan <gustavo.padovan@collabora.co.uk> Reviewed-by: Joonyoung Shim <jy0922.shim@samsung.com> Tested-by: Tobias Jakobi <tjakobi@math.uni-bielefeld.de> Signed-off-by: Inki Dae <inki.dae@samsung.com>
2015-06-20drm/exynos: add exynos specific .atomic_commit()Gustavo Padovan
exynos needs to update planes with the crtc enabled (mainly for the FIMD case) so this specific atomic commit changes the order of drm_atomic_helper_commit_modeset_enables() and drm_atomic_helper_commit_planes() to commit planes after we enable crtc and encoders.

2015-06-19arm64: use private ratelimit state along with show_unhandled_signalsVladimir Murzin
printk_ratelimit() shares the ratelimiting state with other callers what may lead to scenarios where at the time we want to print out debug information we already limited, so nothing appears in the dmesg - this makes exception-trace quite poor helper in debugging. Additionally, we have imbalance with some messages limited with global ratelimit state and other messages limited with their private state defined via pr_*_ratelimited(). To address this inconsistency show_unhandled_signals_ratelimited() macro is introduced and caller sites are converted to use it.

If hardware doesn't support DecodeAssist - a feature that provides more information about the intercept in the VMCB, KVM decodes the instruction and then updates the next_rip vmcb control field. However, NRIP support itself depends on cpuid Fn8000_000A_EDX[NRIPS].

2015-06-19kvm: irqchip: Break up high order allocations of kvm_irq_routing_tableJoerg Roedel
The allocation size of the kvm_irq_routing_table depends on the number of irq routing entries because they are all allocated with one kzalloc call. When the irq routing table gets bigger this requires high order allocations which fail from time to time: qemu-kvm: page allocation failure: order:4, mode:0xd0 This patch fixes this issue by breaking up the allocation of the table and its entries into individual kzalloc calls. These could all be satisfied with order-0 allocations, which are less likely to fail. The downside of this change is the lower performance, because of more calls to kzalloc. But given how often kvm_set_irq_routing is called in the lifetime of a guest, it doesn't really matter much.
