Merge tag 'for-linus-5.9-rc1b-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/xen/tip
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
