I've just done a grep for PageSkip on all .c and .h files in the current
(2.4.0-test6) kernel, and have come up with:
./include/asm-i386/pgtable.h:#define PageSkip(page) (0)
./include/asm-mips/pgtable.h:#define PageSkip(page) (0)
./include/asm-alpha/pgtable.h:#define PageSkip(page) (0)
./include/asm-m68k/pgtable.h:#define PageSkip(page) (0)
./include/asm-ppc/pgtable.h:#define PageSkip(page) (0)
./include/asm-arm/pgtable.h:#define PageSkip(page) (machine_is_riscpc() && test_bit(PG_skip, &(page)->flags))
./include/asm-sh/pgtable.h:#define PageSkip(page) (0)
./include/asm-ia64/pgtable.h:#define PageSkip(page) (0)
./include/asm-mips64/pgtable.h:#define PageSkip(page) test_bit(PG_skip, &(page)->flags)
./include/asm-s390/pgtable.h:#define PageSkip(page) (0)
./arch/arm/mm/init.c: if (PageSkip(page)) {
./arch/mips64/sgi-ip27/ip27-memory.c: if (PageSkip(mem_map+tmp))
Since this macro is only used in two architecture-specific places, is there
any reason to keep it in the header files?
On ARM, I'm planning on moving it out of pgtable.h and into mm/init.c.
