The recent IA64 changes for /proc/kcore broke the access on i386.
Currently no notes are written for the direct mapped or vmalloced
memory, which makes gdb reject it.
This patch fixes it. Other ports probably need to do the same changes.
There is still another problem in /proc/kcore for which I am submitting a
separate patch.
