fa0b31d585 migration: initialise compression_counters for a new migration
If the compression migration fails or is canceled, the query for the value of
compression_counters during the next compression migration is wrong.

458fecca80 migration: provide an error message to migration_cancel()
This avoids to call migrate_get_current() in the caller function
whereas migration_cancel() already needs the pointer to the current
migration state.

835b04ed79 bsd-user: Add stubs for new signal routines
Until the signal support is merged from the bsd-user fork, we need stubs
for cpu_loop_exit_sigsegv and cpu_loop_exit_sigbus to link. These call
abort after logging a message. Since singals aren't supported here
yet, this is sufficient.

6f08c9c531 Revert "elf: Relax MIPS' elf_check_arch() to accept EM_NANOMIPS too"
Per the "P32 Porting Guide" (rev 1.2) [1], chapter 2:

  p32 ABI Overview
  ----------------

  The Application Binary Interface, or ABI, is the set of rules
  that all binaries must follow in order to run on a nanoMIPS
  system. This includes, for example, object file format,
  instruction set, data layout, subroutine calling convention,
  and system call numbers. The ABI is one part of the mechanism
  that maintains binary compatibility across all nanoMIPS platforms.

  p32 improves on o32 to provide an ABI that is efficient in both
  code density and performance. p32 is required for the nanoMIPS
  architecture.

So far QEMU only support the MIPS o32 / n32 / n64 ABIs. The p32 ABI
is not implemented, therefore we can not run any nanoMIPS binary.

Revert commit f72541f3a5 ("elf: Relax MIPS' elf_check_arch() to
accept EM_NANOMIPS too").

See also the "ELF ABI Supplement" [2].

ba7b6f025b target/mips: Fix Loongson-3A4000 MSAIR config register
When using the Loongson-3A4000 CPU, the MSAIR is returned with a
zero value (because unimplemented). Checking on real hardware,
this value appears incorrect:

  $ cat /proc/cpuinfo
  system type     : generic-loongson-machine
  machine         : loongson,generic
  cpu model       : Loongson-3 V0.4  FPU V0.1
  model name      : Loongson-3A R4 (Loongson-3A4000) @ 1800MHz
  isa             : mips1 mips2 mips3 mips4 mips5 mips32r1 mips32r2 mips64r1 mips64r2
  ASEs implemented        : vz msa loongson-mmi loongson-cam loongson-ext loongson-ext2
  ...

Checking the CFCMSA opcode result with gdb we get 0x60140:

  Breakpoint 1, 0x00000001200037c4 in main ()
  1: x/i $pc
  => 0x1200037c4 <main+52>:  cfcmsa       v0,msa_ir
  (gdb) si
  0x00000001200037c8 in main ()
  (gdb) i r v0
  v0: 0x60140

MSAIR bits 17 and 18 are "reserved" per the spec revision 1.12,
so mask them out, and set MSAIR=0x0140 for the Loongson-3A4000
CPU model added in commit af868995e1.

However we directly call the trans_msa_3rf() function,

bbc213b37c target/mips: Adjust style in msa_translate_init()
While the first 'off' variable assignment is unused, it helps
to better understand the code logic. Move the assignation where
it would have been used so it is easier to compare the MSA
registers based on FPU ones versus the MSA specific registers.

36b39a69b2 target/mips: Fix MSA MSUBV.B opcode
The result of the 'Vector Multiply and Subtract' opcode is
incorrect with Byte vectors. Probably due to a copy/paste error,
commit 5f148a0232 mistakenly used the $wt (target register)
instead  of $wd (destination register) as first operand. Fix that.
