From: Mark Rutland Date: Mon, 24 Nov 2014 13:59:30 +0000 (+0000) Subject: arm64: kvm: move to ESR_ELx macros X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=c6d01a947a51193e839516165286bc8d14a0e409;p=openwrt%2Fstaging%2Fblogic.git arm64: kvm: move to ESR_ELx macros Now that we have common ESR_ELx macros, make use of them in the arm64 KVM code. The addition of to the include path highlighted badly ordered (i.e. not alphabetical) include lists; these are changed to alphabetical order. There should be no functional change as a result of this patch.
