In general yes. However this was a side-product of a bug investigation
for ppc, re-reviewing my cpu_index field movement patch.
The user here is cpu_memory_rw_debug(), which for softmmu calls
cpu_get_phys_page_debug(), which in turn is a target-specific global
function. Both have quite a number of callers, so I'd like to schedule
that after my pending qom-cpu-9 refactorings to avoid conflicts, and
cpu_get_phys_page_debug() feels like a candidate for a CPUState callback
to avoid target-specific globals.
Independently, the function needs to stay in exec.c since it uses
TARGET_PAGE_{SIZE,MASK} for its implementation.
I appreciate you thinking of this though!
Thanks, applied to qom-cpu-next (with extended commit message):
