Subject: [PATCH 3/3] tools/hv: Fix permissions of created directory and files

From: Ben Hutchings <ben@...adent.org.uk>

It's silly to create directories without execute permission, or to
give permissions to 'other' but not the group-owner.

Write the permissions in octal and 'ls -l' format since these are much
easier to read than the named macros.
