------------------------------------------------------
From: Toshi Kani <toshi.kani@xxxxxx>
Subject: mm: remove_memory(): fix end_pfn setting
remove_memory() calls walk_memory_range() with [start_pfn, end_pfn), where
end_pfn is exclusive in this range. Therefore, end_pfn needs to be set to
the next page of the end address.
