Subject: x86: 64 bit print out absent pages num too
X-Git-Tag: firefly_0821_release~17024^2~1
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=11a6b0c933b55654a58afd84f63a5dde1607d78f;p=firefly-linux-kernel-4.4.55.git

x86: 64 bit print out absent pages num too

so users are not confused with memhole causing big total ram

we don't need to worry about 32 bit, because memhole is always
above max_low_pfn.
