This is not really supported by malloc.  On the other hand nothing prevents
you from using a different memory allocator.

I'd personally recommend "vmalloc" for this purpose.  It has a reasonable
license and is, I think, available via pkgsrc.  For an embedded target you
will probably have to integrate it into your own source tree but that should
not be too hard.
