LLVM moved their issue tracker from their own Bugzilla instance to

necessarily show the most up to date information around the issues, as
all updates will occur on GitHub, not Bugzilla.
Another complication is that the Bugzilla

-mcmodel=medium. As such, NO_MINIMAL_TOC is no longer being set. Remove

Following patch will use ptdump_check_wx() regardless of
CONFIG_DEBUG_WX, so define it at all times of powerpc and s390
just like other architectures. Though keep the WARN_ON_ONCE()
only when CONFIG_DEBUG_WX is set.
