[1] note: in kernel terms of auxvec.h this stands for AT_HWCAP, see http://lxr.free-electrons.com/source/include/uapi/linux/auxvec.h?a=arm#L24 How Volk handles it looks like AT_HWCAP can only start on a 4-byte-aligned address within auxv; I'm absolutely not sure whether this is correct; on my x86_64 machine, there is no AT_HWCAP in that case.
decided to have a look into this instead of sleeping; man proc(5) and volk are right: AT_HWCAP can only occur every 64 bit in /proc/PID/auxv. Sorry for the confusion.
