Series [1/4] libndctl: Unify adding dimms for papr and nfit families | expand

Commit Message

Santosh Sivaraj March 28, 2021, 2:10 a.m. UTC 
The alignment sizes passed to ndctl in the tests are all hardcoded to 4k,
the default page size on x86. Change those to the default page size on that
architecture (sysconf/getconf). No functional changes otherwise.
