Subject: Remove bogus sanity check from xc_linux_save.
X-Git-Tag: archive/raspbian/4.8.0-1+rpi1~1^2~15396^2~16
X-Git-Url: https://dgit.raspbian.org/?a=commitdiff_plain;h=c5d238206dd1aa8f64e10efe12f031766ebf1e90;p=xen.git

Remove bogus sanity check from xc_linux_save.

(a guest from another host (or an earlier time) can quite validly have
a max_mfn bigger the current max on this host)
