The patch titled
Subject: mm: make !CONFIG_HUGE_PAGE wrappers into static inlines
has been removed from the -mm tree. Its filename was
mm-make-config_huge_page-wrappers-into-static-inlines.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
From: Jason Gunthorpe <jgg@xxxxxxxxxxxx>
Subject: mm: make !CONFIG_HUGE_PAGE wrappers into static inlines
Instead of using defines, which loses type safety and provokes unused
variable warnings from gcc, put the constants into static inlines.
