It turns out that everyone's still getting PAGE_SIZE from <sys/user.h> via <sys/ucontext.h> via <signal.h> anyway. glibc has PAGE_SIZE in <sys/user.h> rather than <limits.h> so this part is good. The bad part is that we have such wide transitive inclusion of <sys/user.h>! Bug: http://b/22735893 Change-Id: I363adffe4a27b4ca1eedf695ea621f5dd2d5ca10
