Caused by commit
259231a04561 ("cpuidle: add poll_limit_ns to cpuidle_device structure")
I have added the following patch for today:
From: Stephen Rothwell <s...@canb.auug.org.au>
Date: Wed, 31 Jul 2019 15:29:52 +1000
Subject: [PATCH] cpuidle: header file stubs must be "static inline"
An x86_64 allmodconfig build produces these errors:
x86_64-linux-gnu-ld: kernel/sched/core.o: in function `cpuidle_poll_time':
core.c:(.text+0x230): multiple definition of `cpuidle_poll_time';
arch/x86/kernel/process.o:process.c:(.text+0xc0): first defined here
(and more)
