Subject: KVM: PPC: Book3S HV: Use ARRAY_SIZE macro
Patch-mainline: v4.15-rc1
Git-commit: 4bb817ed833c070e5b5ee0482f74e2a5e1a12c4c
References: bsc#1077761

Use ARRAY_SIZE macro, rather than explicitly coding some variant of it
yourself.
Found with: find -type f -name "*.c" -o -name "*.h" | xargs perl -p -i -e
's/\bsizeof\s*\(\s*(\w+)\s*\)\s*\ /\s*sizeof\s*\(\s*\1\s*\[\s*0\s*\]\s*\)
/ARRAY_SIZE(\1)/g' and manual check/verification.
