2013-07-09target-i386: Change LOG_PCALL_STATE() argument to CPUStateAndreas Färber1-5/+5

2013-07-09log: Change log_cpu_state[_mask]() argument to CPUStateAndreas Färber30-45/+63
Since commit 878096eeb278a8ac1ccd6667af73e026f29b4cf5 (cpu: Turn cpu_dump_{state,statistics}() into CPUState hooks) CPUArchState is no longer needed. Add documentation and make the functions available through qemu/log.h outside NEED_CPU_H to allow use in qom/cpu.c. Moving them to qom/cpu.h was not yet possible due to convoluted include paths, so that some devices grow an implicit and unneeded dependency on qom/cpu.h for now.

2013-07-09cpu: Drop unnecessary dynamic casts in *_env_get_cpu()Andreas Färber16-16/+16
A transition from CPUFooState to FooCPU can be considered safe, just like FooCPU::env access in the opposite direction. The only benefit of the FOO_CPU() casts would be protection against bogus CPUFooState pointers, but then surrounding code would likely break, too. This should slightly improve interrupt etc. performance when going from CPUFooState to FooCPU. For any additional CPU() casts see 3556c233d931ad5ffa46a35cb25cfc057732ebb8 (qom: allow turning cast debugging off).
