ia64: split off early_ioremap() declarations into asm/early_ioremap.h
Unlike x86, arm64 and ARM, ia64 does not declare its implementations of early_ioremap/early_iounmap/early_memremap/early_memunmap in a header file called <asm/early_ioremap.h> This complicates the use of these functions in generic code, since the header cannot be included directly, and we have to rely on transitive includes, which is fragile. So create a <asm/early_ioremap.h> for ia64, and move the existing definitions into it. Signed-off-by: Ard Biesheuvel <ard.biesheuvel@linaro.org> Signed-off-by: Tony Luck <tony.luck@intel.com>
