This patch series:
- fixes qemu-arm to run static armhf binaries
- shows address of heap in /proc/pid/maps output for all architectures
- optimizes address layout of loaded executable
- increases free heap for guest apps
NOTE:
- this patch series is for qemu v8.1.0-rc ONLY.
- do not apply on top of v8.0-stable series, as those use
a different search algorithm for free mmap memory
and thus will give improper memory layouts.
