x86: update to kernel 3.18

copied target/linux/x86/config-3.14 and target/linux/x86/patches-3.14 to
3.18 equivalents and then tweaked until it built.

Tested on alix2, soekris net4826 and soekris net4521.

Still having trouble with net4826 booting from Grub, alix2 and net4521
are fine.

++Introduction
++============
++
++RDC (http://www.rdc.com.tw) have been manufacturing x86-compatible SoC
++(system-on-chips) for a number of years.  They are not the fastest of
++CPUs (clock speeds ranging from 133-150MHz) but 486SX compatibility
++coupled with very low power consumption[1] and low cost make them ideal
++for embedded applications.
++
++
++Where to find
++=============
++
++RDC chips show up in numerous embedded devices, but be careful since
++many of them will not run Linux 2.6 without significant expertise.
++
++There are several variants of what the linux kernel refers to generically
++as RDC321X:  R8610, R321x, S3282 and AMRISC20000.
++
++R321x: Found in various routers, see the OpenWrt project for details,
++   http://wiki.openwrt.org/oldwiki/rdcport
++
++R8610: Found on the RDC evaluation board
++   http://www.ivankuten.com/system-on-chip-soc/rdc-r8610/
++
++AMRISC20000: Found in the MGB-100 wireless hard disk
++   http://tintuc.no-ip.com/linux/tipps/mgb100/
++
++S3282: Found in various NAS devices, including the Bifferboard
++   http://www.bifferos.com
++
++
++Kernel Configuration
++====================
++
++Add support for this CPU with CONFIG_X86_RDC321X.  Ensure that maths
++emulation is included (CONFIG_MATH_EMULATION selected) and avoid MCE
++(CONFIG_X86_MCE not selected).
++
++
++CPU detection
++=============
++
++None of these chips support the cpuid instruction, so as with some
++other x86 compatible SoCs, we must check the north bridge and look
++for specific 'signature' PCI device config.
++
++The current detection code has been tested only on the Bifferboard
++(S3282 CPU), please send bug reports or success stories with
++other devices to bifferos@yahoo.co.uk.
++
++
++Credits
++=======
++
++Many thanks to RDC for providing the customer codes to allow
++detection of all known variants, without which this detection code
++would have been very hard to ascertain.
++
++
++References
