x86: unify kmap_atomic_pfn() and iomap_atomic_prot_pfn(), fix
Impact: build fix Move kmap_atomic_prot_pfn() to iomap_32.c. It is used on all 32-bit kernels, while highmem_32.c is only built on highmem kernels. ( Note: the debug_kmap_atomic_prot() check is removed for now, that problem is handled via another patch. ) Reported-by: Thomas Gleixner <tglx@linutronix.de> Cc: Akinobu Mita <akinobu.mita@gmail.com> LKML-Reference: <20090311143317.GA22244@localhost.localdomain> Signed-off-by: Ingo Molnar <mingo@elte.hu>
