include/linux/random.h: In function 'add_latent_entropy':
include/linux/random.h:25:46: error: 'latent_entropy' undeclared
Caused by commit 36d4b36b6959 ("lib/nodemask: inline next_node_in() and
node_random()"). Fix is at:
https://www.spinics.net/lists/kernel/msg4468633.html
===========
qemu tests:
Crashes:
Various crashes in pl011_probe() due to commit f2d3b9a46e0e ("ARM: 9220/1:
amba: Remove deferred device addition"). The suggested fix is at
https://lore.kernel.org/lkml/20220811190747.797081-1-isaacmanjarres@google.com/T/
and mostly works but exposes or introduces another crash. The suggested fix for
that crash introduces yet another crash. See
https://lore.kernel.org/lkml/20220811195234.GA4018948@roeck-us.net/T/#m2192446c13d46612a00c4d499da7896d692db75c
for details.
Note: I just saw v2 of the proposed fix. I'll need to retest.
