[petsc-dev] Need mechanism to set LocalToGlobal mapping in a DMShell

[Jed Brown]

It would be natural to have a matching interface, but why do you need it?
You're in charge of making the matrices and vectors so you can give them
local-to-global mappings. The only solver that calls
DMGetLocalToGlobalMapping is PCEXOTIC, which only works with DMDA anyway.
