When booted on pHyp, I see /dev/nvram but not /dev/pstore, even if I turn on CONFIG_PSTORE. Is there something else I need to add? Should we update pseries_defconfig to include CONFIG_PSTORE (which it doesn't include currently)? Maybe turn on panic/oops via CONFIG_PSTORE_RAM too? Other than that, the series looks clean. It's passes my build and boot tests. I've not reviewed the contents of the patches.
