2014-06-11powerpc: Remove check for CONFIG_SERIAL_TEXT_DEBUGPaul Bolle
The Kconfig symbol SERIAL_TEXT_DEBUG was removed from arch/powerpc/Kconfig.debug in v2.6.22. (In v2.6.27 it was also removed from arch/ppc/Kconfig.debug.) So the check for its macro has evaluated to false for over five years now. Remove that check and the few lines of code hidden behind it.

2014-06-11powerpc: Add AT_HWCAP2 to indicate V.CRYPTO category supportBenjamin Herrenschmidt
The Vector Crypto category instructions are supported by current POWER8 chips, advertise them to userspace using a specific bit to properly differentiate with chips of the same architecture level that might not have them.

2014-06-11drm/nv50-: trigger update after all connectors disabledBen Skeggs
We were sending the necessary state changes to unset the mode, but never actually hit the big GO button unless another modeset happens afterwards. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

2014-06-11drm/nouveau/dp: fix support for dpmsBen Skeggs
SOR_PWR has no effect to power-off DP links, unlike other SOR protocols. Instead, on the source side, we cut power to the lanes after having put the sink into D3. Link training takes care of everything required to bring it back again. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2014-06-11drm/nouveau/disp/dp: maintain link in response to hpd signalBen Skeggs
This previously worked for the most part due to userspace doing a modeset in response to HPD interrupts. This will allow us to properly handle cases where sync is lost for other reasons, or if userspace isn't caring. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2014-06-11drm/g94-/disp: bash and wait for something after changing lane power regsBen Skeggs
Some kind of update? Needed to make the power-down take effect at least. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2014-06-11drm/nouveau/disp/dp: split link config/power into two stepsBen Skeggs
We want to be able to power down the lanes for DPMS off. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

2014-06-11drm/nouveau/disp: add internal representaion of output paths and connectorsBen Skeggs
This will, at some point, be used to replace various bits and pieces of code doing direct bios parsing. For now, it'll just be used for some DP improvements. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

2014-06-11drm/nouveau/i2c: introduce locking at a per-port levelBen Skeggs
There's also provisions to allow a pad to be locked with a specific routing, for an indefinite period of time. This will be used in future patches. The G94+ pad driver will now also power-down pads when not required. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2014-06-11drm/nouveau/i2c: balance port acquire/releaseBen Skeggs
This was a half-finished hack before, just enough to handle the shared aux/i2c pad thing on G94 and up. We got lucky with locking etc up until now, as this was (generally) all protected by the DRM mode_config lock. It's about to become a lot more likely to hit the races.

2014-06-10Merge branch 'cxgb4'David S. Miller
Hariprasad Shenai says: ==================== Adds support for CIQ and other misc. fixes for rdma/cxgb4 This patch series adds support to allocate and use IQs specifically for indirect interrupts, adds fixes to align ISS for iWARP connections & fixes related to tcp snd/rvd window for Chelsio T4/T5 adapters on iw_cxgb4. Also changes Interrupt Holdoff Packet Count threshold of response queues for cxgb4 driver. The patches series is created against 'net-next' tree. And includes patches on cxgb4 and iw_cxgb4 driver. Since this patch-series contains cxgb4 and iw_cxgb4 patches, we would like to request this patch series to get merged via David Miller's 'net-next' tree. We have included all the maintainers of respective drivers. Kindly review the change and let us know in case of any review comments. ==================== Signed-off-by: David S.

2014-06-10iw_cxgb4: don't truncate the recv window sizeHariprasad Shenai
Fixed a bug that shows up with recv window sizes that exceed the size of the RCV_BUFSIZ field in opt0 (>= 1024K). If the recv window exceeds this, then we specify the max possible in opt0, add add the rest in via a RX_DATA_ACK credits.
