The system heap can be easily turned into a module by adding the usual MODULE_* macros, importing the proper namespaces and changing the Kconfig symbol to a tristate. This heap won't be able to unload though, since we're missing a lot of infrastructure to make it safe. Reviewed-by: T.J.

Choose this option to enable the system dmabuf heap. The system heap
|
|
is backed by pages from the buddy allocator. If in doubt, say Y.

Choose this option to enable dma-buf CMA heap. This heap is backed
