From 26c99af1018c35020cfad1d20f02acb224807655 Mon Sep 17 00:00:00 2001 From: Victor Kamensky Date: Thu, 12 Jun 2014 09:30:12 -0700 Subject: [PATCH] ARM64: KVM: set and get of sys registers in BE case Since size of all sys registers is always 8 bytes. Current code is actually endian agnostic. Just clean it up a bit. Removed comment about little endian. Change type of pointer from 'void *' to 'u64 *' to enforce stronger type checking.
