2015-03-18exec: Respect as_tranlsate_internal length clampPeter Crosthwaite
address_space_translate_internal will clamp the *plen length argument based on the size of the memory region being queried. The iommu walker logic in addresss_space_translate was ignoring this by discarding the post fn call value of *plen. Fix by just always using *plen as the length argument throughout the fn, removing the len local variable. This fixes a bootloader bug when a single elf section spans multiple QEMU memory regions.

2015-03-18profiler: Reenable built-in profilerAlexey Kardashevskiy
2ed1ebcf6 "timer: replace time() with QEMU_CLOCK_HOST" broke compile when configured with --enable-profiler. Turned out the profiler has been broken for a while. This does s/qemu_time/tcg_time/ as the profiler only works in a TCG mode. This also fixes the compile error. This changes profile_getclock() to return nanoseconds rather than CPU ticks as the "profile" HMP command prints seconds and there is no platform-independent way to get ticks-per-second rate. Since TCG is quite slow and get_clock() returns nanoseconds (fine enough), this should not affect precision much. This removes unused qemu_time_start and tlb_flush_time.

2015-03-18virtio-scsi: Fix assert in virtio_scsi_push_eventFam Zheng
Hotplugging a scsi-disk may trigger the assertion in qemu_sgl_concat. qemu-system-x86_64: qemu/hw/scsi/virtio-scsi.c:115: qemu_sgl_concat: Assertion `skip == 0' failed. This is introduced by commit 55783a55 (virtio-scsi: work around bug in old BIOSes) which didn't check out_num when accessing out_sg[0].iov_len (the same to in sg). For virtio_scsi_push_event, looking into out_sg doesn't make sense because 0 req_size is intended.

The .d file name must match exactly what is used in the SUBDIR_DEVICES_MAK_DEP variable. Instead of making assumptions in the make_device_config.sh script, just pass it in. Similarly, the makefile target may not match the output file name, because Makefile uses a temporary file.

2015-03-17migration: Expose 'cancelling' status to userzhanghailiang
'cancelling' status was introduced by commit 51cf4c1a, mainly to avoid a possible start of a new migration process while the previous one still exists. But we didn't expose this status to user, instead we returned the 'active' state. Here, we expose it to the user (such as libvirt), 'cancelling' status only occurs for a short window before the migration aborts, so for users, if they cancel a migration process, it will observe 'cancelling' status occasionally. Testing revealed that with older libvirt (anything 1.2.13 or less) will print an odd error message if the state is seen, but that the migration is still properly cancelled. Newer libvirt will be patched to recognize the new state without the odd error message.
