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.

1bba0dc932 Rename cpu_reset() to cpu_state_reset()

Don't hide the parameter type behind explicit casts, use static

871708bf39 target-cris/opcode-cris.h: rename REG_PC/SP to CRIS_REG_PC/SP
The REG_PC constant used in opcode-cris.h can clash with a
similar define in system include files. In particular the
Ubuntu Lucid SPARC signal.h will define REG_PC, and since
qemu-common.h now includes signal.h this was causing compile
failures. Rename the constants to avoid this issue.
(NB that REG_SP is not actually used within QEMU.)

3e4571724f exec.h cleanup
Move softmmu_exec.h include directives from target-*/exec.h to
target-*/op_helper.c. Move also various other stuff only used in
op_helper.c there.

Define global env in dyngen-exec.h.

For i386, move wrappers for segment and FPU helpers from user-exec.c
to op_helper.c. Implement raise_exception_err_env() to handle dynamic
CPUState. Move the function declarations to cpu.h since they can be
used outside of op_helper.c context.

LM32, s390x, UniCore32: remove unused cpu_halted(), regs_to_env() and
env_to_regs().

ARM: make raise_exception() static.

Convert
#include "exec.h"
to
#include "cpu.h"
#include "dyngen-exec.h"
and remove now unused target-*/exec.h.

e87b7cb0f0 Remove unused function parameters from gen_pc_load and rename the function
Function gen_pc_load was introduced in commit
d2856f1ad4.
The only reason for parameter searched_pc was
a debug statement in target-i386/translate.c.

Parameter puc was needed by target-sparc until
commit d7da2a1040.

Remove searched_pc from the debug statement and remove both
parameters from the parameter list of gen_pc_load.

As the function name gen_pc_load was also misleading,
it is now called restore_state_to_opc. This new name
was suggested by Peter Maydell, thanks.

v2: Remove last parameter, too, and rename the function.

v3: Fix [] typo in target-arm/translate.c.
    Fix wrong SHA1 object name in commit message (copy+paste error).

tcg_gen_exit_tb takes a parameter of type tcg_target_long,
so the type casts of pointer to long should be replaced by

sizeof(long) != sizeof(void *), especially for w64.
