Andreas Färber bdf7ae5bbd cpu: Introduce CPUClass::synchronize_from_tb() for cpu_pc_from_tb()
Where no extra implementation is needed, fall back to CPUClass::set_pc().

Peter Maydell 6291ad77d7 linux-user: Move cpu_clone_regs() and cpu_set_tls() into linux-user
The functions cpu_clone_regs() and cpu_set_tls() are not purely CPU
related -- they are specific to the TLS ABI for a a particular OS.
Move them into the linux-user/ tree where they belong.

target-lm32 had entirely unused implementations, since it has no
linux-user target; just drop them.

Andreas Färber 0ad6773f11 target-lm32: Update VMStateDescription to LM32CPU
Add a vmstate_lm32_cpu referencing the previous VMStateDescription as a
sub-struct and hook it up to CPUClass::vmsd. Drop cpu_{save,load}().

Andreas Färber 97a8ea5a3a cpu: Replace do_interrupt() by CPUClass::do_interrupt method
This removes a global per-target function and thus takes us one step
closer to compiling multiple targets into one executable.

It will also allow to override the interrupt handling for certain CPU
families.

Andreas Färber 259186a7d2 cpu: Move halted and interrupt_request fields to CPUState
Both fields are used in VMState, thus need to be moved together.
Explicitly zero them on reset since they were located before
breakpoints.

Pass PowerPCCPU to kvmppc_handle_halt().

Andreas Färber 0347d689f7 target-lm32: Let cpu_lm32_init() return LM32CPU
Make the include paths for cpu-qom.h consistent to allow using LM32CPU
in cpu.h.

Turn cpu_init macro into a static inline function returning CPULM32State
for backwards compatibility.

Andreas Färber ae7d54d489 target-lm32/microblaze: Drop second CPU{LM32, MB}State typedef
Commit 9b9a970a23
(target-lm32/microblaze: Typedef struct CPU{MB,LM32}State)
introduced necessary typedefs for cpu_mmu_index() and mmu.h
respectively.

On some GCC versions this leads to "error: redefinition of typedef".

Drop the original typedef to hopefully fix the build.

Andreas Färber 9349b4f9fd Rename CPUState -> CPUArchState
Scripted conversion:
  for file in *.[hc] hw/*.[hc] hw/kvm/*.[hc] linux-user/*.[hc] linux-user/m68k/*.[hc] bsd-user/*.[hc] darwin-user/*.[hc] tcg/*/*.[hc] target-*/cpu.h; do
    sed -i "s/CPUState/CPUArchState/g" $file
  done

All occurrences of CPUArchState are expected to be replaced by QOM CPUState,
once all targets are QOM'ified and common fields have been extracted.
