("target/arm: Fix ptw bugs introduced by FEAT_RME changes")
While I was fixing the ptw bug in the series above, I noticed
that we had a somewhat confusing mix of ptw->in_space and
ptw->in_secure, where in theory the two are supposed to be
in sync and you can figure out the in_secure state from the
in_space. This patch series' principal aim is to clean that
up by removing the in_secure and out_secure fields in the
S1Translate struct.
The first three patches are fixes for (minor) bugs I noticed
while I was trying to do this refactoring because they're
in or around places that were using in_secure.
The next three are basically plumbing: passing ARMSecurityState
arguments instead of boolean is_secure arguments.
The next four patches then can get rid of uses of the
in_secure and out_secure fields and drop them entirely.
Finally, the last four patches are minor bug fixes for
various corner cases that I noticed while I was testing this.
I don't expect to land this series until we reopen for
8.2 development, but I might as well put it out on the
list for review, since I've written it.
thanks
