I was wondering if you could help me out. The git commit b40827fa7268fda8a62490728a61c2856f33830b ("x86-32, mm: Add an initial page table for core bootstrapping") crashes 32-bit PAE Xen PV guests. I am attaching an RFC patch that works around your patch, but honestly I was wondering if there is a better way to make this work for 2.6.37? Any recommendations? Without this patch, a PV 32-bit PAE guest crashes during early bootup as so: mapping kernel into physical memory Xen: setup ISA identity maps about to get started...
