Ian Campbell 86bbc2c235 xen: pin correct PGD on suspend ... Impact: fix Xen guest boot failure commit eefb47f6a1 ("xen: use spin_lock_nest_lock when pinning a pagetable") changed xen_pgd_walk to walk over mm->pgd rather than taking pgd as an argument. This breaks xen_mm_(un)pin_all() because it makes init_mm.pgd readonly instead of the pgd we are interested in and therefore the pin subsequently fails.
