Cover letter [PATCH 0/6] arm64 pmem support
Quoted 10 lines · Robin Murphy

With the latest updates to the pmem API, the arch code contribution becomes very straightforward to wire up - I think there's about as much code here to just cope with the existence of our new instruction as there is to actually make use of it. I don't have access to any NVDIMMs nor suitable hardware to put them in, so this is written purely to spec - the extent of testing has been the feature detection on a v8.2 Fast Model vs. v8.0 systems.

Patch #1 could go in as a fix ahead of the rest; it just needs to come before patch #5 to prevent that blowing up the build.

Modulo my two comments:
