[PATCH AUTOSEL 5.13 001/219] drm/vmwgfx: Fix subresource updates with new contexts

by Sasha Levin

From: Zack Rusin <zackr(a)vmware.com> [ Upstream commit a12be0277316ed923411c9c80b2899ee74d2b033 ] The has_dx variable was only set during the initialization which meant that UPDATE_SUBRESOURCE was never used. We were emulating it with UPDATE_GB_IMAGE but that's always been a stop-gap. Instead of has_dx which has been deprecated a long time ago we need to check for whether shader model 4.0 or newer is available to the device.

[PATCH 5.4] netns: protect netns ID lookups with RCU

by Håkon Bugge

From: Guillaume Nault <gnault(a)redhat.com> __peernet2id() can be protected by RCU as it only calls idr_for_each(), which is RCU-safe, and never modifies the nsid table. rtnl_net_dumpid() can also do lockless lookups. It does two nested idr_for_each() calls on nsid tables (one direct call and one indirect call because of rtnl_net_dumpid_one() calling __peernet2id()). The netnsid tables are never updated. Therefore it is safe to not take the nsid_lock and run within an RCU-critical section instead. Signed-off-by: Guillaume Nault <gnault(a)redhat.com> Signed-off-by: David S.

[PATCH AUTOSEL 4.4 1/2] dt-bindings: mtd: gpmc: Fix the ECC bytes vs. OOB bytes equation
