fef453ee18 tests/acceptance/virtiofs_submounts: use workdir property
For Avocado Instrumented based tests, it's a better idea to just use
the property.  The environment variable is a fall back for tests not
written using that Python API.

b5a86c482d tests/acceptance/boot_linux: rename misleading cloudinit method
There's no downloading happening on that method, so let's call it
"prepare" instead.  While at it, and because of it, the current
"prepare_boot" and "prepare_cloudinit" are also renamed.

The reasoning here is that "prepare_" methods will just work on the
images, while "set_up_" will make them effective to the VM that will
be launched.  Inspiration comes from the "virtiofs_submounts.py"
tests, which this expects to converge more into.

ee6c14d016 tests/acceptance: Re-enable the microblaze test
The microblaze kernel sometimes gets stuck during boot (ca. 1 out of 200
times), so we disabled the corresponding acceptance tests some months
ago. However, it's likely better to check that the kernel is still
starting than to not testing it at all anymore. Move the test to
a separate file, enable it again and check for an earlier console
message that should always appear.

fb6916dd6c accel: introduce AccelCPUClass extending CPUClass
add a new optional interface to CPUClass, which allows accelerators
to extend the CPUClass with additional accelerator-specific
initializations.

This will allow to separate the target cpu code that is specific
to each accelerator, and register it automatically with object
hierarchy lookup depending on accelerator code availability,
as part of the accel_init_interfaces() initialization step.

7827168471 cpu: tcg_ops: move to tcg-cpu-ops.h, keep a pointer in CPUClass
we cannot in principle make the TCG Operations field definitions
conditional on CONFIG_TCG in code that is included by both common_ss
and specific_ss modules.

Therefore, what we can do safely to restrict the TCG fields to TCG-only
builds, is to move all tcg cpu operations into a separate header file,
which is only included by TCG, target-specific code.

This leaves just a NULL pointer in the cpu.h for the non-TCG builds.

This also tidies up the code in all targets a bit, having all TCG cpu
operations neatly contained by a dedicated data struct.

853bfef4e6 target/arm: do not use cc->do_interrupt for KVM directly
cc->do_interrupt is in theory a TCG callback used in accel/tcg only,
to prepare the emulated architecture to take an interrupt as defined
in the hardware specifications,

but in reality the _do_interrupt style of functions in targets are
also occasionally reused by KVM to prepare the architecture state in a
similar way where userspace code has identified that it needs to
deliver an exception to the guest.

In the case of ARM, that includes:

1) the vcpu thread got a SIGBUS indicating a memory error,
   and we need to deliver a Synchronous External Abort to the guest to
   let it know about the error.
2) the kernel told us about a debug exception (breakpoint, watchpoint)
   but it is not for one of QEMU's own gdbstub breakpoints/watchpoints
   so it must be a breakpoint the guest itself has set up, therefore
   we need to deliver it to the guest.

So in order to reuse code, the same arm_do_interrupt function is used.
This is all fine, but we need to avoid calling it using the callback
registered in CPUClass, since that one is now TCG-only.

Fortunately this is easily solved by replacing calls to
CPUClass::do_interrupt() with explicit calls to arm_do_interrupt().

552672bae6 tcg/tci: Fix TCG_REG_R4 misusage
This was removed from tcg_target_reg_alloc_order and
tcg_target_call_iarg_regs on the assumption that it
was the stack.  This was incorrectly copied from i386.
For tci, the stack is R15.

By adding R4 back to tcg_target_call_iarg_regs, adjust the other
entries so that 6 (or 12) entries are still present in the array,
and adjust the numbers in the interpreter.

187f44d9da tcg/tci: Restrict TCG_TARGET_NB_REGS to 16
As noted in several comments, 8 regs is not enough for 32-bit
to perform calls, as currently implemented.  Shortly, we will
rearrange the encoding which will make 32 regs impossible.

We do not simultaneously support div and div2 -- it's one
or the other.  TCI is already using div, so remove div2.

53f405569c tcg/tci: Move stack bounds check to compile-time
The existing check was incomplete:
(1) Only applied to two of the 7 stores, and not to the loads at all.
(2) Only checked the upper, but not the lower bound of the stack.

Doing this at compile time means that we don't need to do it
at runtime as well.

Note that we had two functions of the same name: a 32-bit version
which took two register numbers and a 64-bit version which was a
no-op wrapper for tcg_write_reg.  After this, we are left with
only the 32-bit version.

85bbbf7088 tcg/tci: Inline tci_write_reg32 into all callers
For a 64-bit TCI, the upper bits of a 32-bit operation are
undefined (much like a native ppc64 32-bit operation).  It
simplifies everything if we don't force-extend the result.
