3d5e90a50b Disallow colons in the parameter of "-accel"
Everybody who used something like "-machine accel=kvm:tcg" in the past
might be tempted to specify a similar list with the -accel parameter,
too, for example "-accel kvm:tcg". However, this is not how this
options is thought to be used, since each "-accel" should only take care
of one specific accelerator.

In the long run, we really should rework the "-accel" code completely,
so that it does not set "-machine accel=..." anymore internally, but
is completely independent from "-machine". For the short run, let's
make sure that users cannot use "-accel xyz:tcg", so that we avoid
that we have to deal with such cases in the wild later.

e423455c4f hw/core/loader: Fix possible crash in rom_copy()
Both, "rom->addr" and "addr" are derived from the binary image
that can be loaded with the "-kernel" paramer. The code in
rom_copy() then calculates:

    d = dest + (rom->addr - addr);

and uses "d" as destination in a memcpy() some lines later. Now with
bad kernel images, it is possible that rom->addr is smaller than addr,
thus "rom->addr - addr" gets negative and the memcpy() then tries to
copy contents from the image to a bad memory location. This could
maybe be used to inject code from a kernel image into the QEMU binary,
so we better fix it with an additional sanity check here.

cd4fc14207 hw/m68k/next-cube: Avoid static RTC variables and introduce control register
Coverity currently complains that the "if (0x00 & (0x80 >> (phase - 8))"
in next-cube.c can never be true. Right it is. The "0x00" is meant as value
of the control register of the RTC, which is currently not implemented yet.
Thus, let's add a register variable for this now. However, the RTC
registers are currently defined as static variables in nextscr2_write(),
which is quite ugly. Thus let's also move the RTC variables to the main
machine state instead. In the long run, we should likely even refactor
the whole RTC code into a separate device in a separate file, but that's
something for calm winter nights later... as a first step, cleaning up
the static variables and shutting up the warning from Coverity should
be sufficient.

fb1fc5a82b s390: do not call memory_region_allocate_system_memory() multiple times
s390 was trying to solve limited KVM memslot size issue by abusing
memory_region_allocate_system_memory(), which breaks API contract
where the function might be called only once.

Beside an invalid use of API, the approach also introduced migration
issue, since RAM chunks for each KVM_SLOT_MAX_BYTES are transferred in
migration stream as separate RAMBlocks.

After discussion [1], it was agreed to break migration from older
QEMU for guest with RAM >8Tb (as it was relatively new (since 2.12)
and considered to be not actually used downstream).
Migration should keep working for guests with less than 8TB and for
more than 8TB with QEMU 4.2 and newer binary.
In case user tries to migrate more than 8TB guest, between incompatible
QEMU versions, migration should fail gracefully due to non-exiting
RAMBlock ID or RAMBlock size mismatch.

Taking in account above and that now KVM code is able to split too
big MemorySection into several memslots, partially revert commit
 (bb223055b s390-ccw-virtio: allow for systems larger that 7.999TB)
and use kvm_set_max_memslot_size() to set KVMSlot size to
KVM_SLOT_MAX_BYTES.

023ae9a88a kvm: split too big memory section on several memslots
Max memslot size supported by kvm on s390 is 8Tb,
move logic of splitting RAM in chunks upto 8T to KVM code.

This way it will hide KVM specific restrictions in KVM code
and won't affect board level design decisions. Which would allow
us to avoid misusing memory_region_allocate_system_memory() API
and eventually use a single hostmem backend for guest RAM.

ee35e9684c configure: Remove s390 (31-bit mode) from the list of supported CPUs
On IBM Z, KVM in the kernel is only implemented for 64-bit mode, and
with regards to TCG, we also only support 64-bit host CPUs (see the
check at the beginning of tcg/s390/tcg-target.inc.c), so we should
remove s390 (without "x", i.e. the old 31-bit mode CPUs) from the
list of supported CPUs.

7df1dac5f1 s390: PCI: fix IOMMU region init
The fix in dbe9cf606c shrinks the IOMMU memory region to a size
that seems reasonable on the surface, however is actually too
small as it is based against a 0-mapped address space.  This
causes breakage with small guests as they can overrun the IOMMU window.

Let's go back to the prior method of initializing iommu for now.

c615550df3 qapi: Improve source file read error handling
qapi-gen.py crashes when it can't open the main schema file, and when
it can't read from any schema file.  Lazy.

Change QAPISchema.__init__() to take a file name instead of a file
object.  Move the open code from _include() to __init__(), so it's
used for the main schema file, too.

Move the read into the try for good measure, and rephrase the error
message.

Reporting open or read failure for the main schema file needs a
QAPISourceInfo representing "no source".  Make QAPISourceInfo cope
with fname=None.
