We try to write index registers into cache when we write an index
register, but we change the reg value before updating the cache.
As a result, the cache is never be updated. This patch will fix
this issue and also correct some incorrect default value in the
cache.

This is two different fixes, you need to send each one in a different
patch - there's not any code overlap between the changes.
