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 #$ Link: https://lkml.kernel.org/r/20210531091908.1738465-2-aisheng.dong@nxp.com Signed-off-by: Dong Aisheng <aisheng.dong@nxp.com> Suggested-by: Yu Zhao <yuzhao@google.com> Reviewed-by: Yu Zhao <yuzhao@google.com> Cc: Andrey Konovalov <andreyknvl@gmail.com> Cc: Catalin Marinas <catalin.marinas@arm.com> Cc: Kees Cook <keescook@chromium.org> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
