The patch titled
Subject: mm: drop SECTION_SHIFT in code comments
has been removed from the -mm tree. Its filename was
mm-drop-section_shift-in-code-comments.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
From: Dong Aisheng <aisheng.dong@xxxxxxx>
Subject: mm: drop SECTION_SHIFT in code comments
Actually SECTIONS_SHIFT is used in the kernel code, so the code comments
is strictly incorrect. And since commit bbeae5b05ef6 ("mm: move page
flags layout to separate header"), SECTIONS_SHIFT definition has been
moved to include/linux/page-flags-layout.h, since code itself looks quite
straighforward, instead of moving the code comment into the new place as
well, we just simply remove it.
This also fixed a checkpatch complain derived from the original code:
WARNING: please, no space before tabs
+ * SECTIONS_SHIFT ^I^I#bits space required to store a section #$
