[PATCH 0/4] PR28824, relro security issues

[Alan Modra]

The first two patches in this series fix relro protection for all
targets that might be running with MAXPAGESIZE larger than
COMMONPAGESIZE memory pages.  They also fix pr28734, the extra page
gap between text and data segments when relro.

See the first patch for lots of detail on what is going on.  I'll
leave this series a few days before committing in case someone spots a
bug or has constructive comments.
