2015-07-09cpu-exec: Purge all uses of ENV_GET_CPU()Peter Crosthwaite
Remove un-needed usages of ENV_GET_CPU() by converting the APIs to use CPUState pointers and retrieving the env_ptr as minimally needed. Scripted conversion for target-* change: for I in target-*/cpu.h; do sed -i \ 's/\(^int cpu_[^_]*_exec(\)[^ ][^ ]* \*s);$/\1CPUState *cpu);/' \ $I; done Signed-off-by: Peter Crosthwaite <crosthwaite.peter@gmail.com> Signed-off-by: Andreas Färber <afaerber@suse.de>

2015-06-21target-microblaze: Preserve the pvr registers during resetAlistair Francis
Move the Microblaze PVR registers to the end of the CPUMBState and preserve them during reset. This is similar to what the QEMU ARM model does with some of it's registers. This allows the Microblaze PVR registers to only be set once at realise instead of constantly at reset.

2015-01-20exec.c: Drop TARGET_HAS_ICE define and checksPeter Maydell
The TARGET_HAS_ICE #define is intended to indicate whether a target-* guest CPU implementation supports the breakpoint handling. However, all our guest CPUs have that support (the only two which do not define TARGET_HAS_ICE are unicore32 and openrisc, and in both those cases the bp support is present and the lack of the #define is just a bug). So remove the #define entirely: all new guest CPU support should include breakpoint handling as part of the basic implementation.
