I am confused then a little bit if emulated case is not an issue.
For 4- and 8-byte cases for xchg .aqrl is used, for relaxed and aqcuire
version of xchg barries are used.
The similar is done for cmpxchg.
If something will be needed to change in emulation loop it won't
require to change 4- and 8-byte cases.

This numbers are incorrect for RISC-V, it should be 12 + 9 ( PAGE_SHIFT
+ VPN_BITS ).
I did some comparision of how some macros are defined in PPC and missed
to update that.

ded that is not to provide

I understand your point about "#define cmpxchg(ptr, o, n) __cmpxchg(",
but I can't undestand how the definition of __cmxchng should be done
