d5ab9713d2 Avoid allocating TCG resources in non-TCG mode
Do not allocate TCG-only resources like the translation buffer when
running over KVM or XEN. Saves a "few" bytes in the qemu address space
and is also conceptually cleaner.

4b5dfd8246 user: Restore debug usage message for '-d ?' in user mode emulation
The code which prints the debug usage message on '-d ?' for *-user
has to come before the check for "not enough arguments", so that
"qemu-foo -d ?" prints the list of possible debug log items rather than
the generic usage message. (This was inadvertently broken in commit
c235d73.)

c235d7387c Command line support for altering the log file location
Add command line support for logging to a location other than /tmp/qemu.log.

With logging enabled (command line option -d), the log is written to
the hard-coded path /tmp/qemu.log. This patch adds support for writing
the log to a different location by passing the -D option.

73b01960b4 PPC: Make DCR uint32_t
For what I know DCR is always 32 bits wide, so we should also use uint32_t to
pass it along the stacks.

This fixes a warning when compiling qemu-system-ppc64 with KVM enabled, making
it compile without --disable-werror

e3ea652962 PPC64: Fix timebase
On PPC we have a 64-bit time base. Usually (PPC32) this is accessed using
two separate 32 bit SPR accesses to SPR_TBU and SPR_TBL.

On PPC64 the SPR_TBL register acts as 64 bit though, so we get the full
64 bits as return value. If we only take the lower ones, fine. But Linux
wants to see all 64 bits or it breaks.

This patch makes PPC64 Linux work even after TB crossed the 32-bit boundary,
which usually happened a few seconds after bootup.

1b530a6dfc Add new command line option -singlestep for tcg single stepping.
This replaces a compile time option for some targets and adds
this feature to targets which did not have a compile time option.

Add monitor command to enable or disable single step mode.

Modify monitor command "info status" to display single step mode.

e1833e1f96 Rework PowerPC exceptions model to make it more versatile:
* don't use exception vectors as the exception number.
  Use vectors numbers as defined in the PowerPC embedded specification instead
  and extend this model to cover all emulated PowerPC variants exceptions.
* add some missing exceptions definitions, from PowerPC 2.04 specification
  and actual PowerPC implementations.
* add code provision for hypervisor exceptions handling.
* define exception vectors and prefix in CPUPPCState to emulate BookE exception
  vectors without any hacks.
* define per CPU model valid exception vectors.
* handle all known exceptions in user-mode only emulations.
* fix hardware interrupts priorities in most cases.
* change RET_EXCP macros name into GEN_EXCP as they don't return.
* do not stop translation on most instructions that are not defined as
  context-synchronizing in PowerPC specification.
* fix PowerPC 64 jump targets and link register update when in 32 bits mode.
* Fix PowerPC 464 and 464F definitions.
