kcore: register text area in generic way
Some 64bit arch has special segment for mapping kernel text. It should be entried to /proc/kcore in addtion to direct-linear-map, vmalloc area. This patch unifies KCORE_TEXT entry scattered under x86 and ia64. I'm not familiar with other archs (mips has its own even after this patch) but range of [_stext ..._end) is a valid area of text and it's not in direct-map area, defining CONFIG_ARCH_PROC_KCORE_TEXT is only a necessary thing to do. Note: I left mips as it is now.
