Set kernel version to 4.2
We switch from using our own tree, to building with upstream tarballs.
Currently we still require a small number of out of tree patches; this
list will shrink as we get the last of the patches upstream, to the
point where will just set the version.
The patches are generated from the tree at
https://github.com/open-power/linux still, and imported into the
buildroot overlay.

+Subject: [PATCH 6/9] powerpc/kexec: Reset secondary cpu endianess before kexec
+
+If the target kernel does not inlcude the FIXUP_ENDIAN check, coming
+from a different-endian kernel will cause the target kernel to panic.
+All ppc64 kernels can handle starting in big-endian mode, so return to
+big-endian before branching into the target kernel.
+
+This mainly affects pseries as secondaries on powernv are returned to
+OPAL.

+Subject: [PATCH 7/9] powerpc/kexec: Reset HILE before kexec_sequence
+
+On powernv secondary cpus are returned to OPAL, and will then enter
+the target kernel in big-endian. However if it is set the HILE bit
+will persist, causing the first exception in the target kernel to be
+delivered in litte-endian regardless of the current endianess.
+
+If running on top of OPAL make sure the HILE bit is reset once we've
+finished waiting for all of the secondaries to be returned to OPAL.
