Peter suggested the rename here:

Since they don't have the same prototype, they clash:

There are ~180 uses of set_feature(CPUARMState,...) and 10 of
set_feature(uint64_t,...) (kvm32:4 kvm64:6).
We are going to remove kvm32, so replacing 180 set_feature(env) by
set_feature(env->features) seems a waste.
If you prefer to avoid renaming as kvm_set_feature() another option is
to move the declaration in a local "features.h" header that would not be
included by kvm*.c.
The main problem is the use of the ARMHostCPUFeatures structure which
apparently was introduced similar to a CPUClass (commit a96c0514ab7)
then lost this in commit c4487d76d52.
