Subject: [PATCH 3.12 001/113] x86/Kconfig: Simplify X86_IO_APIC dependencies

From: Jan Beulich <JBeulich@...e.com>

3.12-stable review patch.  If anyone has any objections, please let me know.

===============

commit b1da1e715d4faf01468b7f45f7098922bc85ea8e upstream.

Since dependencies are transitive, we don't really need to
repeat those of X86_UP_IOAPIC.

Furthermore avoid the symbol getting entered into .config when
it is off by having the default simply Y and the dependencies
solely handled via the intended for that purpose "depends on".
