+Subject: [PATCH] ProcessExecutableMemory.cpp: fix virtual address length on
+ ia64
+
+ia64's usable virtual address space is page dependent. For 16K
+pages with 3 levels of page tables de can address only 44 bits
+of virtual memory, not default 47.
+
+The change makes page size detection dynamic and adapts to
+addressable bits. On ia64 it is '4 * log2(page_size/8)'.
