The naming is really painful, so a trivial suggestion: could we just name all the
Linux side bits 'asid' or 'ctx_id' (even in x86 arch code) and only use 'PCID'
nomenclature in the very lowest level code?

I.e. rename pcid_live_cpus et al and most functions to the asid or ctx_id or asid
naming scheme or so. That would hide most of the naming ugliness.

Thanks,

Ingo
