The structure returned from r600_audio_status() is only partially initialized, and older gcc versions (4.3 and 4.4) warn about this: drivers/gpu/drm/radeon/r600_hdmi.c: In function 'r600_audio_status': drivers/gpu/drm/radeon/r600_hdmi.c:108: error: 'status.id' is used uninitialized in this function drivers/gpu/drm/radeon/r600_hdmi.c:108: error: 'status.connected' is used uninitialized in this function drivers/gpu/drm/radeon/r600_hdmi.c:108: error: 'status.offset' is used uninitialized in this function This is harmless and surprisingly correct in C99, as the caller only accesses the fields that got initialized, so newer compilers don't warn about it, but initializing the entire structure feels like the right thing to do here and avoids the warning.

However, when $clsname is 'matchall', a systematic crash can be observed in htb_classify(). HTB and classful qdiscs don't assign initial value to struct tcf_result, but then they expect it to contain valid values after filters have been run. Thus, current 'matchall' ignores the TCA_MATCHALL_CLASSID attribute, configured by user, and makes HTB (and classful qdiscs) dereference random pointers. By assigning head->res to *res in mall_classify(), before the actions are invoked, we fix this crash and enable TCA_MATCHALL_CLASSID functionality, that had no effect on 'matchall' classifier since its first introduction.

This reverts commit bbdf0b2ff32a ("drm/i915/bxt: Disable device ready before shutdown command"). Disable device ready before shutdown command was added previously to avoid a split screen issue seen on dual link DSI panels. As of now, dual link is not supported and will need some rework in the upstream code. For single link DSI panels, the change is not required. This will cause failure in sending SHUTDOWN packet during disable. Hence reverting the change. Will handle the change as part of dual link enabling in upstream.

If no spinlock debugging options (CONFIG_GENERIC_LOCKBREAK, CONFIG_DEBUG_SPINLOCK, CONFIG_DEBUG_LOCK_ALLOC) are enabled on a UP platform (e.g. m68k defconfig), arch_spinlock_t is an empty struct, hence using ARRAY_SIZE(nf_nat_locks) causes a division by zero: net/netfilter/nf_nat_core.c: In function ‘nf_nat_setup_info’: net/netfilter/nf_nat_core.c:432: warning: division by zero net/netfilter/nf_nat_core.c: In function ‘__nf_nat_cleanup_conntrack’: net/netfilter/nf_nat_core.c:535: warning: division by zero net/netfilter/nf_nat_core.c:537: warning: division by zero net/netfilter/nf_nat_core.c: In function ‘nf_nat_init’: net/netfilter/nf_nat_core.c:810: warning: division by zero net/netfilter/nf_nat_core.c:811: warning: division by zero net/netfilter/nf_nat_core.c:824: warning: division by zero Fix this by using the CONNTRACK_LOCKS definition instead.

2017-09-18arm64: ensure the kernel is compiled for LP64Andrew Pinski
The kernel needs to be compiled as a LP64 binary for ARM64, even when using a compiler that defaults to code-generation for the ILP32 ABI. Consequently, we need to explicitly pass '-mabi=lp64' (supported on gcc-4.9 and newer).

2017-09-18drm/i915/guc: Cleanup adding GuC work itemsMichał Winiarski
We can just operate on the wq_tail directly (in the process descriptor). This allows us to remove the duplicated tail from the client. While I'm here let's also remove the constants kept in the client and document our locking requirements. This causes a small change in one of GuC debugfs files. We're no longer reporting constant values (which I don't think is a problem), but we're also no longer reporting the tail (does anyone care?). v2: Update tail after wqi contents.

2017-09-18drm/i915/guc: Simplify GuC doorbell logicMichał Winiarski
All we're really doing is incrementing a simple counter in a doorbell_info struct. We can do without extra variables and a separate counter kept in guc_client. Since it's gone, we're also removing its debugfs. The only functional change here, is that we're no longer treating 0 as a special value. GuC doesn't seem to care, why should we? v2: Restore desc->tail update. v3: Drop the retry loop, assert that doorbell cookie doesn't change behind our back. v4: WARN rather than BUG, use xchg.

2017-09-18drm/i915/guc: Submit GuC workitems containing coalesced requestsMichał Winiarski
To create an upper bound on number of GuC workitems, we need to change the way that requests are being submitted. Rather than submitting each request as an individual workitem, we can do coalescing in a similar way we're handlig execlist submission ports. We also need to stop pretending that we're doing "lite-restore" in GuC submission (we would create a workitem each time we hit this condition). This allows us to completely remove the reservation, replacing it with a compile time check. v2: Also coalesce when replaying on reset (Daniele) v3: Consistent wq_resv - per-request (Daniele) v4: Squash removing wq_resv v5: Reflect i915_guc_submit argument changes in doc v6: Rebase on top of execlists reset/restart fix (Chris,Michał) References: https://bugs.freedesktop.org/show_bug.cgi?id=101873 Cc: Chris Wilson <chris@chris-wilson.co.uk> Cc: Daniele Ceraolo Spurio <daniele.ceraolospurio@intel.com> Cc: Jeff McGee <jeff.mcgee@intel.com> Cc: Michal Wajdeczko <michal.wajdeczko@intel.com> Cc: Oscar Mateo <oscar.mateo@intel.com> Signed-off-by: Michał Winiarski <michal.winiarski@intel.com> Reviewed-by: Chris Wilson <chris@chris-wilson.co.uk> Link: https://patchwork.freedesktop.org/patch/msgid/20170914083216.10192-2-michal.winiarski@intel.com Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
