The patch titled
Subject: um: kill pfn_t
has been removed from the -mm tree. Its filename was
um-kill-pfn_t.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
From: Dan Williams <dan.j.williams@xxxxxxxxx>
Subject: um: kill pfn_t
The core has developed a need for a "pfn_t" type [1]. Convert the usage
of pfn_t by usermode-linux to an unsigned long, and update pfn_to_phys()
to drop its expectation of a typed pfn.
