Subject: [patch 9/9] x86/callthunks: Use EXPORT_PER_CPU_SYMBOL_GPL() for per CPU variables
Date: Mon,  4 Mar 2024 11:12:29 +0100 (CET)	[thread overview]
Message-ID: <20240304005104.841915535@linutronix.de> (raw)
In-Reply-To: 20240303235029.555787150@linutronix.de

sparse complains rightfully about the usage of EXPORT_SYMBOL_GPL() for per
CPU variables:

callthunks.c:346:20: sparse: warning: incorrect type in initializer (different address spaces)
callthunks.c:346:20: sparse:    expected void const [noderef] __percpu *__vpp_verify
callthunks.c:346:20: sparse:    got unsigned long long *

Use EXPORT_PER_CPU_SYMBOL_GPL instead.
