Pull more xen updates from Juergen Gross: - Remove support for running as 32-bit Xen PV-guest. 32-bit PV guests are rarely used, are lacking security fixes for Meltdown, and can be easily replaced by PVH mode. Another series for doing more cleanup will follow soon (removal of 32-bit-only pvops functionality). - Fixes and additional features for the Xen display frontend driver. * tag 'for-linus-5.9-rc1b-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/xen/tip: drm/xen-front: Pass dumb buffer data offset to the backend xen: Sync up with the canonical protocol definition in Xen drm/xen-front: Add YUYV to supported formats drm/xen-front: Fix misused IS_ERR_OR_NULL checks xen/gntdev: Fix dmabuf import with non-zero sgt offset x86/xen: drop tests for highmem in pv code x86/xen: eliminate xen-asm_64.S x86/xen: remove 32-bit Xen PV guest support

Pull module updates from Jessica Yu: "The most important change would be Christoph Hellwig's patch implementing proprietary taint inheritance, in an effort to discourage the creation of GPL "shim" modules that interface between GPL symbols and proprietary symbols. Summary: - Have modules that use symbols from proprietary modules inherit the TAINT_PROPRIETARY_MODULE taint, in an effort to prevent GPL shim modules that are used to circumvent _GPL exports. These are modules that claim to be GPL licensed while also using symbols from proprietary modules.

If you right-click the first row in the option tree, the pop-up menu shows up, but if you right-click the second row or below, the event is ignored due to the following check: if (e->y() <= header()->geometry().bottom()) { Perhaps, the intention was to show the pop-menu only when the tree header was right-clicked, but this handler is not called in that case. Since the origin of e->y() starts from the bottom of the header, this check is odd. Going forward, you can right-click anywhere in the tree to get the pop-up menu.

These icon data are used by ConfigItem, but stored in each instance of ConfigView. There is no point to keep the same data in each of 3 instances, "menu", "config", and "search".

To avoid some issues, for example RCU usage warning and double free, we should flush the flows under ovs_lock. This patch refactors table_instance_destroy and introduces table_instance_flow_flush which can be invoked by __dp_destroy or ovs_flow_tbl_flush.

After @blk_fill_in_prog_lock is acquired there is an early out vnet situation that can occur. In that case, the rwlock needs to be released. Also, since @blk_fill_in_prog_lock is only acquired when @tp_version is exactly TPACKET_V3, only release it on that exact condition as well. And finally, add sparse annotation so that it is clearer that prb_fill_curr_block() and prb_clear_blk_fill_status() are acquiring and releasing @blk_fill_in_prog_lock, respectively. sparse is still unable to understand the balance, but the warnings are now on a higher level that make more sense.
