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

Fix the alternate time base the same way as the default timebase. SPR_ATBL
should return a 64-bit value on 64 bit implementations.
Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>
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.

In the very least, a change like this requires discussion on the list.
The naming convention is goofy and it causes a massive merge problem. Something
like this _must_ be presented on the list first so people can provide input
and cope with it.
This reverts commit 99a0949b72.

This replaces a compile time option for some targets and adds
this feature to targets which did not have a compile time option.

Introduce noreturn attribute and attach it to cpu_loop_exit as well as
interrupt/exception helpers for i386. This avoids a bunch of gcc4
warnings.
[ Note that this patch comes with a workaround to include qemu-common.h
even in cases where is currently causes conflicts with dyngen-exec.h.
I've been told that these conflicts will get resolved in the future
(/me will try to have a look as well - as time permits). ]

According to $GCC/gcc/config/rs6000/rs6000-c.c _ARCH_PPC is the

PowerPC, on 64bit platforms _ARCH_PPC64 will be also defined.
