[PATCH v2 4/5] apparmor: qemu access to @{PROC}/*/auxv for hw_cap

From: Stefan Bader <stefan.bader(a)canonical.com&gt; On some architectures (ppc, s390x, sparc, arm) qemu will read auxv to detect hardware capabilities via qemu_getauxval. Allow that access read-only for the entry owned by the current qemu process.
