The patch titled
     Subject: powerpc: inline huge vmap supported functions
has been removed from the -mm tree.  Its filename was
     powerpc-inline-huge-vmap-supported-functions.patch

This patch was dropped because it was merged into mainline or a subsystem tree

------------------------------------------------------
From: Nicholas Piggin <npiggin@gmail.com>
Subject: powerpc: inline huge vmap supported functions

This allows unsupported levels to be constant folded away, and so
p4d_free_pud_page can be removed because it's no longer linked to.
