Hello,

v3 attached is a more concise single patch that adds support for MSVC on Win11 ARM64.  The issues fixed are mostly related to config, build, docs, an implementation of spin_delay() and a change to S_UNLOCK() macro.  I've squished the work we did into a single commit and improved the commit message.  Thomas, I think in another thread you mentioned that some of what Dave added came from you, correct?  We should add you as another author if so, right?

best.
