1bba0dc932 Rename cpu_reset() to cpu_state_reset()
Frees the identifier cpu_reset for QOM CPUs (manual rename).

Don't hide the parameter type behind explicit casts, use static
functions with strongly typed argument to indirect.

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 "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).

d4c430a80f Large page TLB flush
QEMU uses a fixed page size for the CPU TLB.  If the guest uses large
pages then we effectively split these into multiple smaller pages, and
populate the corresponding TLB entries on demand.

When the guest invalidates the TLB by virtual address we must invalidate
all entries covered by the large page.  However the address used to
invalidate the entry may not be present in the QEMU TLB, so we do not
know which regions to clear.

Implementing a full vaiable size TLB is hard and slow, so just keep a
simple address/mask pair to record which addresses may have been mapped by
large pages.  If the guest invalidates this region then flush the
whole TLB.

91a7593526 target-mips: fix user-mode emulation startup
Running programs with the MIPS user-mode emulator fails during dynamic
loading, as floating-point instructions are not enabled in in
env->hflags.  Move the code for doing so from fpu_init to cpu_reset so
the MIPS_HFLAG_{FPU,F64} setting doesn't get clobbered by cpu_reset
setting env->hflags to MIPS_HFLAG_UM.

The same end can be achieved by swapping the ordering of fpu_init and
cpu_reset in cpu_mips_init, but it seemed better to consolidate the
CONFIG_USER_ONLY code into a single location.

The only changes to shared code are in handle_delay_slot.  We need to

ISAMode the low bit of the target address for jump-to-register.

Also, since we're now adding bits that can be in MIPS_HFLAG_BMASK_EXT,
make sure we use MIPS_HFLAG_BMASK_BASE in the places where we just want
basic information about a branch.

7b270ef2a3 target-mips: fix single-stepping
Single-stepping branches on MIPS didn't work right, because the
generation of EXCP_DEBUG happened after the generation of the code to
exit the current TB.  That is, given the code:

    bne v0,v1,target
    nop
    ...
  target:
    addu v0,v0,v1
  1:

when you single-stepped through the NOP, execution wouldn't actually
halt until you reached the label `1'.

This patch corrects that and also changes single-stepping so that a
branch and its delay slot are executed as one instruction for the
purposes of single-stepping.  This behavior is comparable to what other
MIPS tools (e.g. MIPSsim with MDI) do.  GDB avoids placing breakpoints
in branch delay slots, so this change doesn't break anything on the GDB
side.

get_fp_bit returns the bit number of the condition code, not a

1ad2134f91 Hardware convenience library
The only target dependency for most hardware is sizeof(target_phys_addr_t).
Build these files into a convenience library, and use that instead of
building for every target.

Remove and poison various target specific macros to avoid bogus target
dependencies creeping back in.

Big/Little endian is not handled because devices should not know or care
about this to start with.

c276471991 The _exit syscall is used for both thread termination in NPTL applications,
and process termination in legacy applications.  Try to guess which we want
based on the presence of multiple threads.

Also implement locking when modifying the CPU list.

eca1bdf415 Log reset events (Jan Kiszka)
Original idea&code by Kevin Wolf, split-up in two patches and added more
archs.

This patch introduces a flag to log CPU resets. Useful for tracing
unexpected resets (such as those triggered by x86 triple faults).

d12d51d5ba Clean up debugging code #ifdefs (Eduardo Habkost)
Use macros to avoid #ifdefs on debugging code.

This patch doesn't try to merge logging macros from different files,
but just unify the debugging code #ifdefs onto a macro on each file. A
further cleanup can unify the debugging macros on a common header, later
