[PATCH 0/3] spapr NVDIMM: consider 'nvdimm' machine option

[Daniel Henrique Barboza]

This series aims to solve bug [1].

First patch is a trivial cleanup, feel free to squash into
patch 02. Patch 02 attempts a code simplification to put
all NVDIMM related logic in the same function.

Patch 03 is where the actual fix is implemented. My initial
approach here was to make the handling of '-machine nvdimm' for
pSeries similar to how it is handled elsewhere, but I wasn't
able to accomplish that without either (1) breaking up existing
pseries-5.1 guests that didn't care about this option or (2)
make pseries-5.1 and pseries-5.2+ machines to have different
semantics for it.

I ended up doing what I was sure was sensible: if the user puts
'-machine nvdimm=off', we must comply to that.

  ppc/spapr_nvdimm: use g_autofree in spapr_nvdimm_validate_opts()
  spapr, spapr_nvdimm: fold NVDIMM validation in the same place
  ppc/spapr_nvdimm: do not enable support with 'nvdimm=off'
