Since v1:

This series reduce the footprint of the QEMU binary:
.bss: 106KiB (moved to .heap)
Why is moving stuff from .bss to .heap beneficial? With .bss,
0-initialization is cheap (the OS gives it to us for free by mapping the
entire .bss to a copy-on-write zero page); but with .heap, we generally
have to zero it at runtime ourselves.
.data: 1MiB
.rodata: 4.34MiB
But reducing these sizes makes sense.
