openjdk uses guard pages, triggers fault logs in syslog

vm_page_fault: vm_soft_fault returned error 'Permission denied' on fault at 0x100100, ip 0xcb84a81, write 0, user 1, thread 0x260
vm_page_fault: thread "pthread func" (608) in team "java" (593) tried to read address 0x100100, ip 0xcb84a81 ("mmap area" +0x5a81)
write access attempted on write-protected area 0x35b4 at 0x00101000
vm_page_fault: vm_soft_fault returned error 'Permission denied' on fault at 0x101b80, ip 0x2519e55, write 1, user 1, thread 0x260
vm_page_fault: thread "pthread func" (608) in team "java" (593) tried to write address 0x101b80, ip 0x2519e55 ("libjvm.so_seg0ro" +0x287e55)

Maybe the vm subsystem should check if the page owner is the current process before logging anything.

The "vm_page_fault: thread ..." part of this was fixed in hrev52518.
