If machine doesn't support memory hotplug then staring QEMU
with initial memory less than default will make QEMU exit with
following error message:

$QEMU -m 16  -M isapc
qemu-system-i386: "-memory 'slots|maxmem'" is not supported by: isapc

Set maxram_size to initial memory value before parsing
'maxmem' option allows to keep maxmem in sync with initial
memory size if no maxmem option was specified.

OK this is a regression fix so we need it for 2.1.

Applied, thanks!

Hopefully this hasn't been forgotten. This is a bad regression for
pre v2.1 pc machine types.
