Actually I had also said in that earlier mail: "If, otoh, you left that VA management to (an extended version of) vmap(), by e.g. allowing the caller to request allocation from a different VA range (much like iirc x86-64 Linux handles its modules address range allocation), things would be different. After all the VA management is the important part here, while the backing memory allocation is just a trivial auxiliary operation." I.e. elaboration here really just consists of the referral to the respective Linux approach.
