Here are 13 patches against the 'next-20221014' tag of the 'linux-next.git'
repo. I'm not sure how this cross-arch series should be merged -- perhaps
thru Andrew Morton's tree?
user_regset_copyin_ignore() apparently cannot fail and so always returns 0.

Commit 78e5a3399421 ("cpumask: fix checking valid cpu range") has
started issuing warnings[*] when cpu indices equal to nr_cpu_ids - 1
are passed to cpumask_next* functions. seq_read_iter() and cpuinfo's
start and next seq operations implement a pattern like
