4add73aa60 virtio: serial: expose a 'guest_writable' callback for users
Users of virtio-serial may want to know when a port becomes writable.  A
port can stop accepting writes if the guest port is open but not being
read from.  In this case, data gets queued up in the virtqueue, and
after the vq is full, writes to the port do not succeed.

When the guest reads off a vq element, and adds a new one for the host
to put data in, we can tell users the port is available for more writes,
via the new ->guest_writable() callback.

46db7b862a hmp: Fix definition of command quit
The command handler is a union of two function types.  If
cmd->user_print is set, handle_user_command() calls
cmd->mhandler.cmd_new(), else cmd->mhandler.cmd().

Command definitions must therefore either set both user_print() and
mhandler.cmd_new(), or only mhandler.cmd().

quit's sets user_print and mhandler.cmd().  handle_user_command()
calls hmp_quit() through mhandler.cmd_new() rather than
mhandler.cmd(), i.e. through a function pointer with a different type.
Broken in commit 7a7f325, v1.0.

Works in practice because hmp_quit() doesn't use its arguments, and
handle_user_command() ignores its function value.

c3c1bb99d1 exec: Respect as_tranlsate_internal length clamp
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.

89d5cbddee profiler: Reenable built-in profiler
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.

2034e324da virtio-scsi: Fix assert in virtio_scsi_push_event
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.  Instead of making assumptions on what the
Makefile does, emit the config-devices.mak file to stdout, and use the
passed-in destination as the makefile target
