Subject: [PATCH 5.10 0/1] qrtr: Convert qrtr_ports from IDR to XArray

Syzkaller reports using smp_processor_id() in preemptible code at
radix_tree_node_alloc() in 5.10 stable releases. The problem has 
been fixed by the following patch which can be cleanly applied to 
the 5.10 branch.

Found by Linux Verification Center (linuxtesting.org) with Syzkaller.
