This issue seems to have returned with F22:

# dmesg | grep -i kvm
[    0.298500] kvm [1]: GICV size 0x2000 not a multiple of page size 0x10000
[    0.298597] kvm [1]: error initializing Hyp mode: -6

# uname -a
Linux mustang.home 4.0.0-0.rc5.git4.1.fc22.aarch64 #1 SMP Thu Apr 2 09:22:12
UTC 2015 aarch64 aarch64 aarch64 GNU/Linux

There's a bug report here too: https://bugzilla.redhat.com/show_bug.cgi?id=1208768
