The patch titled
Subject: proc/vmcore: let pfn_is_ram() return a bool
has been removed from the -mm tree. Its filename was
proc-vmcore-let-pfn_is_ram-return-a-bool.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
From: David Hildenbrand <david@xxxxxxxxxx>
Subject: proc/vmcore: let pfn_is_ram() return a bool
The callback should deal with errors internally, it doesn't make sense to
expose these via pfn_is_ram(). We'll rework the callbacks next. Right
now we consider errors as if "it's RAM"; no functional change.
