Seeking reviewers for patch; PR 193873

[Meyer, Conrad]

Hi all,

The patch[0] dedupes dumpsys() somewhat, leaving MD-specific support code for a few things (map/unmap a region, flush CPU writeback cache, iterate physmem segments).

jhibbits@ is taking a look, but he'd like another pair of eyeballs. The more, the merrier! If someone could throw the latest patch up in phabricator for discussion, that would be awesome.

I'll also need someone willing to commit it, I'm not a committer.

Questions/concerns/feedback?

Thanks,
Conrad
