Subject: log: Permit -dfilter 0..0xffffffffffffffff
X-Git-Tag: qemu-xen-4.8.0-rc1~143^2~14
X-Git-Url: http://xenbits.xensource.com/gitweb?a=commitdiff_plain;h=58eeb83cc7c445f167c951493deddf45621d66bb;p=qemu-xen.git

log: Permit -dfilter 0..0xffffffffffffffff

Works fine since the previous commit fixed the underlying range data
type.  Of course it filters out nothing, but so does
0..1,2..0xffffffffffffffff, and we don't bother rejecting that either.
