From 4d4b0ae9c82f34e6cc445f9b04248ae49346a73e Mon Sep 17 00:00:00 2001 From: Thomas Gleixner Date: Fri, 13 Nov 2020 15:02:09 +0100 Subject: [PATCH 115/323] sh: Get rid of nmi_count() Origin: https://www.kernel.org/pub/linux/kernel/projects/rt/5.10/older/patches-5.10.204-rt100.tar.xz nmi_count() is a historical leftover and SH is the only user. Replace it with regular per cpu accessors.
