mm/memremap: drop unused SECTION_SIZE and SECTION_MASK
SECTION_SIZE and SECTION_MASK macros are not getting used anymore. But they do conflict with existing definitions on arm64 platform causing following warning during build. Lets drop these unused macros. mm/memremap.c:16: warning: "SECTION_MASK" redefined #define SECTION_MASK ~((1UL << PA_SECTION_SHIFT) - 1) arch/arm64/include/asm/pgtable-hwdef.h:79: note: this is the location of the previous definition #define SECTION_MASK (~(SECTION_SIZE-1)) mm/memremap.c:17: warning: "SECTION_SIZE" redefined #define SECTION_SIZE (1UL << PA_SECTION_SHIFT) arch/arm64/include/asm/pgtable-hwdef.h:78: note: this is the location of the previous definition #define SECTION_SIZE (_AC(1, UL) << SECTION_SHIFT) Link: http://lkml.kernel.org/r/1569312010-31313-1-git-send-email-anshuman.khandual@arm.com Signed-off-by: Anshuman Khandual <anshuman.khandual@arm.com> Reported-by: kbuild test robot <lkp@intel.com> Reviewed-by: David Hildenbrand <david@redhat.com> Cc: Dan Williams <dan.j.williams@intel.com> Cc: Jason Gunthorpe <jgg@ziepe.ca> Cc: Logan Gunthorpe <logang@deltatee.com> Cc: Ira Weiny <ira.weiny@intel.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
