91d0b151de hw/intc/loongson_ipi: Implement IOCSR address space for MIPS
Implement IOCSR address space get functions for MIPS/Loongson CPUs.

For MIPS/Loongson without IOCSR (i.e. Loongson-3A1000), get_cpu_iocsr_as
will return as null, and send_ipi_data will fail with MEMTX_DECODE_ERROR,
which matches expected behavior on hardware.

39b3ae11b0 hw/intc/loongarch_ipi: Remove pointless MAX_CPU check
Since cpuid will be checked by ipi_getcpu anyway, there is
no point to enforce MAX_CPU here.

This also saved us from including loongarch board header.

but due to our current Kconfig setup, the FDC code is still always

The i440fx and the isa-pc machine currently always instantiate
the FDC, so we have to add the select statements now there instead.

09d98a241c hw/ppc/spapr_pci: Replace g_memdup() by g_memdup2()

  The old API took the size of the memory to duplicate as a guint,
  whereas most memory functions take memory sizes as a gsize. This
  made it easy to accidentally pass a gsize to g_memdup(). For large
  values, that would lead to a silent truncation of the size from 64
  to 32 bits, and result in a heap area being returned which is
  significantly smaller than what the caller expects. This can likely
  be exploited in various modules to cause a heap buffer overflow.

Replace g_memdup() by the safer g_memdup2() wrapper.

Trivially safe because the argument was directly from sizeof.

When at it, slightly cleanup the lines around:

  results in detached mode.

  - Add "postcopy" keyword to "resume/-r" help messages, as it only applies

c55deb860c migration: Deprecate fd: for file migration
The fd: URI can currently trigger two different types of migration, a
TCP migration using sockets and a file migration using a plain
file. This is in conflict with the recently introduced (8.2) QMP
migrate API that takes structured data as JSON-like format. We cannot
keep the same backend for both types of migration because with the new
API the code is more tightly coupled to the type of transport. This
means a TCP migration must use the 'socket' transport and a file
migration must use the 'file' transport.

If we keep allowing fd: when using a file, this creates an issue when
the user converts the old-style (fd:) to the new style ("transport":
"socket") invocation because the file descriptor in question has
previously been allowed to be either a plain file or a socket.

To avoid creating too much confusion, we can simply deprecate the fd:
+ file usage, which is thought to be rarely used currently and instead
establish a 1:1 correspondence between fd: URI and socket transport,
and file: URI and file transport.

dbea1c89da qapi: introduce exit-on-error parameter for migrate-incoming
Now we do set MIGRATION_FAILED state, but don't give a chance to
orchestrator to query migration state and get the error.

Let's provide a possibility for QMP-based orchestrators to get an error
like with outgoing migration.

For hmp_migrate_incoming(), let's enable the new behavior: HMP is not
and ABI, it's mostly intended to use by developer and it makes sense
not to stop the process.

For x-exit-preconfig, let's keep the old behavior:
 - it's called from init(), so here we want to keep current behavior by
   default
 - it does exit on error by itself as well
So, if we want to change the behavior of x-exit-preconfig, it should be
another patch.

d4e6d40c36 target/i386: remove duplicate prefix decoding
Now that a bulk of opcodes go through the new decoder, it is sensible
to do some cleanup.  Go immediately through disas_insn_new and only jump
back after parsing the prefixes.

disas_insn() now only contains the three sigsetjmp cases, and they
are more easily managed if they are inlined into i386_tr_translate_insn.

These are unlikely to be converted to the table-based decoding
soon (perhaps there could be generic ESC decoding in decode-new.c.inc
for the Mod/RM byte, but not operand decoding), so keep them separate
