[petsc-dev] Enabling single precision for MUMPS and SUPERLU

[Hong Zhang]

Stefano:
Are you sure these patches are made out of the latest petsc-dev?
I get
petsc:/sandbox/hzhang/petsc-dev>patch -Np1 < superlu_patch_single.diff

Similar error on mumps_patch_single.diff.

Patching petsc-3.3 is successful though.

Barry: do you agree with Stefano's approach?

Hong, attached please find the two patches split.
