asm-generic, mm: pgtable: convert my_zero_pfn() to macros to fix build
Commit 816422ad7647 ("asm-generic, mm: pgtable: consolidate zero page
helpers") broke the compile on MIPS if SPARSEMEM is enabled. We get
this:
In file included from arch/mips/include/asm/pgtable.h:552,
from include/linux/mm.h:44,
from arch/mips/kernel/asm-offsets.c:14:
include/asm-generic/pgtable.h: In function 'my_zero_pfn':
include/asm-generic/pgtable.h:466: error: implicit declaration of function 'page_to_section'
In file included from arch/mips/kernel/asm-offsets.c:14:
include/linux/mm.h: At top level:
include/linux/mm.h:738: error: conflicting types for 'page_to_section'
include/asm-generic/pgtable.h:466: note: previous implicit declaration of 'page_to_section' was here
Due header files inter-dependencies, the only way I see to fix it is
convert my_zero_pfn() for __HAVE_COLOR_ZERO_PAGE to macros.
