Hello,
This is an RFC cleanup series removing the unused
arch_{spin,read,write}_relax macros from (nearly) all architectures that
define them. The macros have no users in core code and are typically
synonymous with cpu_relax(), the notable exceptions being PowerPC (where
the thing is still unused) and S390.
S390 does actually use the relax macros internally, as part of the
spinlock implementation, in order to yield the CPU when a virtual CPU
is spinning. For that reason, I've left arch_spin_relax alone there.
Feedback welcome,
Will
