Merge remote-tracking branch 'remotes/pmaydell/tags/pull-target-arm-20150316' into staging
target-arm queue:
* fix handling of execute-never bits in page table walks
* tell kernel to initialize KVM GIC in realize function
* fix handling of STM (user) with r15 in register list
* ignore low bit of PC in M-profile exception return
* fix linux-user get/set_tls syscalls on CPUs with TZ
# gpg: Signature made Mon Mar 16 12:39:04 2015 GMT using RSA key ID 14360CDE
# gpg: Good signature from "Peter Maydell <peter.maydell@linaro.org>"
