7de2e85653 yank: Unregister function when using TLS migration 
After yank feature was introduced in migration, whenever migration
is started using TLS, the following error happens in both source and
destination hosts:

(qemu) qemu-kvm: ../util/yank.c:107: yank_unregister_instance:
Assertion `QLIST_EMPTY(&entry->yankfns)' failed.

This happens because of a missing yank_unregister_function() when using
qio-channel-tls.

Fix this by also allowing TYPE_QIO_CHANNEL_TLS object type to perform
yank_unregister_function() in channel_close() and multifd_load_cleanup().

Also, inside migration_channel_connect() and
migration_channel_process_incoming() move yank_register_function() so
it only runs once on a TLS migration.

Fixes: b5eea99ec2 ("migration: Add yank feature", 2021-01-13)

Changes since v2:
- Dropped all references to ioc->master
- yank_register_function() and yank_unregister_function() now only run
  once in a TLS migration.

Changes since v1:
- Cast p->c to QIOChannelTLS into multifd_load_cleanup()

Besides, tcg_gen_gvec_*_ptr calls simd_desc in it's implementation.

719f0f603c target/riscv: fix wfi exception behavior 
The wfi exception trigger behavior should take into account user mode,
hstatus.vtw, and the fact the an wfi might raise different types of
exceptions depending on various factors:

If supervisor mode is not present:

- an illegal instruction exception should be generated if user mode
executes and wfi instruction and mstatus.tw = 1.

If supervisor mode is present:

- when a wfi instruction is executed, an illegal exception should be triggered
if either the current mode is user or the mode is supervisor and mstatus.tw is
set.

Plus, if the hypervisor extensions are enabled:

- a virtual instruction exception should be raised when a wfi is executed from
virtual-user or virtual-supervisor and hstatus.vtw is set.

143897b501 hw/riscv: microchip_pfsoc: Support direct kernel boot 
At present the Microchip Icicle Kit machine only supports using
'-bios' to load the HSS, and does not support '-kernel' for direct
kernel booting just like other RISC-V machines do. One has to use
U-Boot which is chain-loaded by HSS, to load a kernel for testing.
This is not so convenient.

Adding '-kernel' support together with the existing '-bios', we
follow the following table to select which payload we execute:

  -bios |    -kernel | payload
  ------+------------+--------
      N |          N | HSS
      Y | don't care | HSS
      N |          Y | kernel

This ensures backwards compatibility with how we used to expose
'-bios' to users. When '-kernel' is used for direct boot, '-dtb'
must be present to provide a valid device tree for the board,
as we don't generate device tree.

When direct kernel boot is used, the OpenSBI fw_dynamic BIOS image
is used to boot a payload like U-Boot or OS kernel directly.

Documentation is updated to describe the direct kernel boot. Note
as of today there is still no PolarFire SoC support in the upstream
Linux kernel hence the document does not include instructions for
that. It will be updated in the future.

cb53b283b5 hw/riscv: sifive_u: Switch to use qemu_fdt_setprop_string_array() helper 
Since commit 78da6a1bca ("device_tree: add qemu_fdt_setprop_string_array helper"),
we can use the new helper to set the clock name for the ethernet
controller node.

31fa83bd2b tests/tcg/configure.sh: tweak quoting of target_compiler 
If you configure the host compiler with a multi-command stanza like:

  --cc="ccache gcc"

then the configure.sh machinery falls over with confusion. Work around
this by ensuring we correctly quote so where we need a complete
evaluation we get it. Of course the has() check needs single variable
so we need to unquote that. This does mean it essentially checks that
just the ccache command exits but if we got past that step we still
check the compiler actually does something.

81c4edc39e tests/tcg: add a multiarch signals test to stress test signal delivery 
This adds a simple signal test that combines the POSIX timer_create
with signal delivery across multiple threads. The aim is to provide a
bit more of a stress test to flush out signal handling issues for
easily than the occasional random crash we sometimes see in linux-test
or threadcount.
