I can add a Kconfig option for it, but since there is no Kconfig for the rheap
itself, I didn't know where to put it. Once Sylvain's patch is accepted, I
can update this patch by adding this Kconfig option:
int "Default size (in KB) of the rheap bootmem allocator"
This is the default size (in KB) of the boot memory to allocate (via
alloc_bootmem). This value can be overridden on the kernel command
line using the "rhbootmem" option (e.g. "rhbootmem=2M")
One thing I don't like, however, is the name. It doesn't really make sense to
call it the "rheap bootmem allocator" because the fact that it uses an rheap
is hidden from the callers of rheap_bootmem_alloc().
