[PATCH v3 16/25] x86: Make get_ramdisk_{image|size}() global.

From: Tang Chen <hidden>
Date: 2013-08-07 11:15:52
Also in: linux-acpi, lkml
Subsystem: the rest, x86 architecture (32-bit and 64-bit) · Maintainers: Linus Torvalds, Thomas Gleixner, Ingo Molnar, Borislav Petkov, Dave Hansen

In the following patches, we need to call get_ramdisk_{image|size}()
to get initrd file's address and size. So make these two functions
global.

v1 -> v2:
As tj suggested, make these two function static inline in
arch/x86/include/asm/setup.h.
