Yes, the latest ahci-xgene patches depends on the library-ise patches
too, and the 'library-ise' patches have been in -next tree already.

Without these KVM patches, qemu can't boot a kernel on APM
mustang, also I just found these patches have been merged
to -next tree already, see below:

https://git.kernel.org/cgit/linux/kernel/git/next/linux-next.git/log/?id=refs%2Ftags%2Fnext-20140312&qt=author&q=Marc+Zyngier+

So they should land 3.15 if everything is OK.
