Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2013-11-08drm/nouveau/i2c: use a custom bitbanging delay for the adt7473Martin Peres
This patch adds a way to define a custom delay when scanning for i2c devices because the adt7473 sometimes doesn't like the default bitbanging udelay. Signed-off-by: Martin Peres <martin.peres@labri.fr> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2013-11-08drm/nouveau/agp: add a quirk list to limit agp modesIlia Mirkin
Certain combinations of hardware can't actually support the maximum detected speed. Add a quirk list that lists pairs of hostbridge/chip pci ids and the mode that they should work with.

2013-11-08drm/nv50-nv86,nv92/mc: rearm msi via pci config space, rather than mmio mirrorBen Skeggs
This is what NVIDIA do on these chipsets, let's hope it works around the reported MSI failures for us on NV86. v2: updated to include G92, as per information provided by NVIDIA. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2013-11-08drm/nvc0,nvc4/mc: handle 0xc0's "special" msi rearmBen Skeggs

2013-11-08drm/nouveau/mc: bracket interrupt handler with NV_PMC_INTR_EN disable/re-enableBen Skeggs
This looks to be what NVIDIA do pretty much everywhere, since forever. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2013-11-08drm/nouveau/mc: have single entry and exit points to the interrupt handlerBen Skeggs

2013-11-08drm/nouveau/mc: msi rearm write via subdev, not deviceBen Skeggs
This way we can catch it with debugging on for PMC subdev. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2013-11-08drm/nouveau/therm: ack any pending IRQ at initMartin Peres
This is safe because ptherm hasn't been configured yet and will be a little further down the initialization path. Ptherm should be safe regarding to runtime reconfiguration. v2: - do not limit this patch to nv84-a3 and make it nv84+ v3: - move the ack to fini() - disable IRQs on fini() - silently ignore un-requested IRQs Signed-off-by: Martin Peres <martin.peres@labri.fr> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2013-11-08drm/nv31/mpeg: split the nv31 and nv40 dma setting implementationsIlia Mirkin
NV31 has different config bits than NV40+ do. Also fix the DMA_IMAGE VRAM-only setting to check the right bits. Signed-off-by: Ilia Mirkin <imirkin@alum.mit.edu> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2013-11-08drm/nv31/mpeg: store chan singleton in engine, use it for dispatchIlia Mirkin
This makes nv31+ able to actually perform the nv_call, since previously the inst was not available. Signed-off-by: Ilia Mirkin <imirkin@alum.mit.edu> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2013-11-08drm/nv40/mpeg: use the nv31-provided classesIlia Mirkin
Since nv40 only covers pre-nv44 now, it can use the nv31-provided functions. Signed-off-by: Ilia Mirkin <imirkin@alum.mit.edu> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2013-11-08drm/nv44/mpeg: create a copy of the nv31/nv40 implsIlia Mirkin
The nv31/nv40 impls are actually fairly nv44-specific, since they assume the presence of the instance register/context switching. Create a copy before nv31/nv40 get fixed. Signed-off-by: Ilia Mirkin <imirkin@alum.mit.edu> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2013-11-08drm/nv31/mpeg: no need to set compat mode differently for nv44 grIlia Mirkin

2013-11-08drm/nv10: fix chipset checks, mostly for the benefit of nv1aIlia Mirkin
NV1A is numerically higher than NV17 but generationally lower. Use the new card type to help disambiguate. Signed-off-by: Ilia Mirkin <imirkin@alum.mit.edu> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2013-11-08drm/nv10: introduce a new NV_11 card typeIlia Mirkin
NV11/17/1F/18 come after NV10/15/16/1A. In order to facilitate using numerical comparisons, split up the two sets into different card types. This change should be a no-op except that the relevant cards will see NV11 printed instead of NV10 for the family.

2013-11-08drm/nouveau: fix backlight mask on ppc powerbookIlia Mirkin
This code was originally moved to using nv_mask by d31e078d84. This should not have any actual effect since the mask isn't applied to the value. Signed-off-by: Ilia Mirkin <imirkin@alum.mit.edu> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

2013-11-08drm/nouveau/core: split lock into list+exec and enable refcount locksBen Skeggs
This fixes a reported locking inversion when interacting with the DRM core's vblank routines. Reviewed-by: Maarten Lankhorst <maarten.lankhorst@canonical.com> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2013-11-08drm/nouveau/core: convert event handler apis to split create/enable semanticsBen Skeggs
This is a necessary step towards being able to work with the insane locking requirements of the DRM core's vblank routines, and a nice cleanup as a side-effect. This is similar in spirit to the interfaces that Peter Hurley arrived at with his nouveau_event rcu conversion series. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

2013-11-08drm/nouveau/core: Allow asymmetric nouveau_event_get/_putPeter Hurley
Most nouveau event handlers have storage in 'static' containers (structures with lifetimes nearly equivalent to the drm_device), but are dangerously reused via nouveau_event_get/_put. For example, if nouveau_event_get is called more than once for a given handler, the event handler list will be corrupted.

2013-11-08drm/nouveau/core: Move event index check from critical sectionPeter Hurley
The index_nr field is constant for the lifetime of the event, so serialized access is unnecessary. Signed-off-by: Peter Hurley <peter@hurleysoftware.com> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2013-11-08drm/nouveau/core: Add priv field for event handlersPeter Hurley

2013-11-08ext4: use prandom_u32() instead of get_random_bytes()Theodore Ts'o
Many of the uses of get_random_bytes() do not actually need cryptographically secure random numbers. Replace those uses with a call to prandom_u32(), which is faster and which doesn't consume entropy from the /dev/random driver. Signed-off-by: "Theodore Ts'o" <tytso@mit.edu>
2013-11-08f2fs: fix memory leak after kobject init failed in fill_superChao Yu
If we failed to init&add kobject when fill_super, stats info and proc object of f2fs will not be released. We should free them before we finish fill_super. Signed-off-by: Chao Yu <chao2.yu@samsung.com> Signed-off-by: Jaegeuk Kim <jaegeuk.kim@samsung.com>

2013-11-07ext4: remove unreachable code after ext4_can_extents_be_merged()Eric Sandeen
Commit ec22ba8e ("ext4: disable merging of uninitialized extents") ensured that if either extent under consideration is uninit, we decline to merge, and ext4_can_extents_be_merged() returns false. So there is no need for the caller to then test whether the extent under consideration is unitialized; if it were, we wouldn't have gotten that far. The comments were also inaccurate; ext4_can_extents_be_merged() no longer XORs the states, it fails if *either* is uninit.

2013-11-07Merge branch 'pskb_put'David S. Miller
Mathias Krause says: ==================== move pskb_put (was: IPsec improvements) This series moves pskb_put() to the core code, making the code duplication in caif obsolete (patches 1 and 2). Patch 3 fixes a few kernel-doc issues. v2 of this series does no longer contain the skb_cow_data() patch and therefore no performance improvements for IPsec. The change is still under discussion, but otherwise independent from the above changes. Please apply! v2: - kernel-doc fixes for pskb_put, as noticed by Ben - dropped skb_cow_data patch as it's still discussed - added a kernel-doc fixes patch (patch 3) ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
