Boris Ostrovsky	6a92b11169	x86/EISA: Don't probe EISA bus for Xen PV guests ... For unprivileged Xen PV guests this is normal memory and ioremap will not be able to properly map it. While at it, since ioremap may return NULL, add a test for pointer's validity.

Thomas Gleixner	ef1d4deab9	x86/eisa: Add missing include ... The seperation of the EISA init missed to include linux/io.h which breaks the build with some special configurations.

Thomas Gleixner	f7eaf6e00f	x86/boot: Move EISA setup to a separate file ... EISA has absolutely nothing to do with traps, so move it out of traps.c into its own eisa.c file. Furthermore, the EISA bus detection does not need to run during very early boot, it's good enough to run it before the EISA bus and drivers are initialized. I.e. instead of calling it from the very early trap_init() code, make it a subsys_initcall().
