With the 64-bit requirement removed from virt CPU accounting,
allow ARM platforms to enable it.

I think you got confused here. HAVE_VIRT_CPU_ACCOUNTING is the arch capability
for VIRT_CPU_ACCOUNTING_NATIVE, not for VIRT_CPU_ACCOUNTING_GEN that only requires
support for context tracking.

Yes, I am confused. :/

That's my bad, all those names start to be confusing now.
The VIRT based Kconfig naming is a bit weird, that doesn't really reflect what the feature
is doing. "Virtual cputime accounting" just doesn't give any clue, except perhaps suggesting
the stuff deals with virtualization while it actually has nothing to do with.
I don't even know what virtual refers to here.

Same goes for vtime based APIs. In fact I just based my work on the legacy that was
there and expanded further the non-sense ;-)

I'll need to do a big renaming one day.

But to begin with I should rename s/HAVE_VIRT_CPU_ACCOUNTING/HAVE_VIRT_CPU_ACCOUNTING_NATIVE.

OK, I just tested and I can indeed drop this patch.

Thanks for clarifying,

Kevin
