From: Marc Zyngier Date: Thu, 4 Oct 2018 08:35:35 +0000 (+0100) Subject: ARM: KVM: Correctly order SGI register entries in the cp15 array X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=ec876f4b252c4084acad259ce3e65ad97f44f040;p=openwrt%2Fstaging%2Fblogic.git ARM: KVM: Correctly order SGI register entries in the cp15 array The ICC_ASGI1R and ICC_SGI0R register entries in the cp15 array are not correctly ordered, leading to a BUG() at boot time. Move them to their natural location.
