Merge remote-tracking branch 'remotes/bonzini/tags/for-upstream' into staging
* Guest ABI fixes for PC machines (hw_version) * Fixes for recent Perl * John Snow's configure fixes * file-backed RAM improvements (Igor, Pavel) * -Werror=clobbered fixes (Stefan) * Kill -d ioport * Fix qemu-system-s390x * Performance improvement for kvmclock migration # gpg: Signature made Thu 05 Nov 2015 13:42:27 GMT using RSA key ID 78C7AE83 # gpg: Good signature from "Paolo Bonzini <bonzini@gnu.org>" # gpg: aka "Paolo Bonzini <pbonzini@redhat.com>" * remotes/bonzini/tags/for-upstream: iscsi: Translate scsi sense into error code Revert "Introduce cpu_clean_all_dirty" kvmclock: add a new function to update env->tsc. configure: disable FORTIFY_SOURCE under clang backends/hostmem-file: Allow to specify full pathname for backing file configure: disallow ccache during compile tests cpu-exec: Fix compiler warning (-Werror=clobbered) memory: call begin, log_start and commit when registering a new listener megasas: Use qemu_hw_version() instead of QEMU_VERSION osdep: Rename qemu_{get, set}_version() to qemu_{, set_}hw_version() pc: Set hw_version on all machine classes qemu-log: remove -d ioport ioport: do not use CPU_LOG_IOPORT target-i386: fix pcmpxstrx equal-ordered (strstr) mode scripts/text2pod.pl: Escape left brace file_ram_alloc: propagate error to caller instead of terminating QEMU Signed-off-by: Peter Maydell <peter.maydell@linaro.org>
