config is attached.
It faults in fork syscall, down in pgd_walk(). It finds a pmd entry
pointing to a machine page where the mfn_to_pfn translation returns -1
aka 0xffffffff. Trying to find a struct page for that one doesn't work ...
kernel with debug printk's:
xen_pgd_pin c1abb000
g 0: 1abe001 1ae61001 <- pgd (index, val, val_ma)
m 0: 80b067 1a394067 <- pmd (same)
m 1: 80c067 1a393067
m 2: 80d067 1a392067

m 427: d067 1a57e067
mfn_to_pfn: mfn 3f400 pfn ffffffff
mfn_to_pfn: mfn 3f400 pfn ffffffff
m 428: fffff0a1 3f4000a1 <- here is the broken one
