I tried compiling this, and got a break in x86_xen_kdump_load_page_PAE.The way the code was effectively commented out there was incompatible with gcc 3.3.6.I'm not sure if the code was meant to be elided.Thanks for the quick turn on my bug ;-)

Can you be more specific?  The code is certainly not supposed to
be "effectively commented out":

$ nm -Bn crash | grep x86_xen_kdump
080eccef t x86_xen_kdump_p2m_create
080ed5ec t x86_xen_kdump_load_page
080ed75d t x86_xen_kdump_load_page_PAE
080ed76a t x86_xen_kdump_page_mfn
080ed89a t x86_xen_kdump_page_mfn_PAE
$

...so I'm sure don't understand what the compiler error is?
