2016-10-21arm/arm64: KVM: Map the BSS at HYPMarc Zyngier
When used with a compiler that doesn't implement "asm goto" (such as the AArch64 port of GCC 4.8), jump labels generate a memory access to find out about the value of the key (instead of just patching the code). The key itself is likely to be stored in the BSS. This is perfectly fine, except that we don't map the BSS at HYP, leading to an exploding kernel at the first access. The obvious fix is simply to map the BSS there (which should have been done a long while ago, but hey...).

2016-10-21arm64: KVM: Take S1 walks into account when determining S2 write faultsWill Deacon
The WnR bit in the HSR/ESR_EL2 indicates whether a data abort was generated by a read or a write instruction. For stage 2 data aborts generated by a stage 1 translation table walk (i.e. the actual page table access faults at EL2), the WnR bit therefore reports whether the instruction generating the walk was a load or a store, *not* whether the page table walker was reading or writing the entry. For page tables marked as read-only at stage 2 (e.g. due to KSM merging them with the tables from another guest), this could result in livelock, where a page table walk generated by a load instruction attempts to set the access flag in the stage 1 descriptor, but fails to trigger CoW in the host since only a read fault is reported. This patch modifies the arm64 kvm_vcpu_dabt_iswrite function to take into account stage 2 faults in stage 1 walks. Since DBM cannot be disabled at EL2 for CPUs that implement it, we assume that these faults are always causes by writes, avoiding the livelock situation at the expense of occasional, spurious CoWs. We could, in theory, do a bit better by checking the guest TCR configuration and inspecting the page table to see why the PTE faulted. However, I doubt this is measurable in practice, and the threat of livelock is real.

Currently it's entirely possible to go through the link training step without first determining the lane_count, which is silly since we end up doing a bunch of aux transfers of size = 0, as highlighted by WARN_ON(!msg->buffer != !msg->size), and can only ever result in a 'failed to update link training' message. This can be observed during intel_dp_long_pulse where we can do the link training step, but before we have had a chance to set the link params. To avoid this we add an extra check for the lane_count in intel_dp_check_link_status, which should prevent us from doing the link training step prematurely. v2: add WARN_ON_ONCE and FIXME comment (Ville) References: https://bugs.freedesktop.org/show_bug.cgi?id=97344 Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Cc: Mika Kahola <mika.kahola@intel.com> Signed-off-by: Matthew Auld <matthew.auld@intel.com> Link: http://patchwork.freedesktop.org/patch/msgid/1476912593-10019-1-git-send-email-matthew.auld@intel.com Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com>

2016-10-21drm/i915: Respect alternate_ddc_pin for all DDI portsVille Syrjälä
The VBT provides the platform a way to mix and match the DDI ports vs. GMBUS pins. Currently we only trust the VBT for DDI E, which I suppose has no standard GMBUS pin assignment. However, there are machines out there that use a non-standard mapping for the other ports as well. Let's start trusting the VBT on this one for all ports on DDI platforms. I've structured the code such that other platforms could easily start using this as well, by simply filling in the ddi_port_info.

2016-10-21drm/i915: Respect alternate_aux_channel for all DDI portsVille Syrjälä
The VBT provides the platform a way to mix and match the DDI ports vs. AUX channels. Currently we only trust the VBT for DDI E, which has no corresponding AUX channel of its own. However it is possible that some board might use some non-standard DDI vs. AUX port routing even for the other ports. Perhaps for signal routing reasons or something, So let's generalize this and trust the VBT for all ports. For now we'll limit this to DDI platforms, as we trust the VBT a bit more there anyway when it comes to the DDI ports. I've structured the code in a way that would allow us to easily expand this to other platforms as well, by simply filling in the ddi_port_info. v2: Drop whitespace changes, keep MISSING_CASE() for unknown aux ch assignment, include a commit message, include debug message during init Cc: stable@vger.kernel.org Cc: Maarten Maathuis <madman2003@gmail.com> Tested-by: Maarten Maathuis <madman2003@gmail.com> References: https://bugs.freedesktop.org/show_bug.cgi?id=97877 Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Link: http://patchwork.freedesktop.org/patch/msgid/1476208368-5710-2-git-send-email-ville.syrjala@linux.intel.com Reviewed-by: Jim Bride <jim.bride@linux.intel.com>

2016-10-21kernel/irq: Export irq_set_parent()Sudip Mukherjee
The TPS65217 driver grew interrupt support which uses irq_set_parent(). While it's not yet clear why this is used in the first place, building the driver as a module fails with: ERROR: ".irq_set_parent" [drivers/mfd/tps65217.ko] undefined! The correctness of the driver change is still investigated, but for now it's less trouble to export irq_set_parent() than dealing with the build wreckage.

2016-10-21target/tcm_fc: use CPU affinity for responsesHannes Reinecke
The libfc stack assigns exchange IDs based on the CPU the request was received on, so we need to send the responses via the same CPU. Otherwise the send logic gets confuses and responses will be delayed, causing exchange timeouts on the initiator side.
