[Qemu-devel] [PATCH 37/37] target-i386: cleanup cpu_x86_find_by_name(), only fill x86_def_t in it

[Igor Mammedov]

Do in cpu_x86_find_by_name() only what name implies. i.e. leave only
cpudef search and copy/fill passed in x86_def_t structure.

and move out of it cpu_model parsing and CPU initializing into
cpu_x86_register(). Plus add hints to where blocks should go when
cpu_x86_register() is disbanded.
