+ [Impact]
+ lshw is not using smbios to obtain hardware information. This is causing lshw to report incorrect information to user. For example I have a machine which has one physical CPU with 8 cores and 32G of RAM. lshw is reporting the machine has only one physical CPU with 0 cores and 32162MiB of RAM.
  
- cat /proc/meminfo | grep MemTotal
- MemTotal:        1542260 kB
+ [Test case]
+ Run lshw and compare its reported values with what you know the physical system has. To help simplify testing I use this script http://paste.ubuntu.com/16900290/ which can be run with the command `sudo lshw -xml | ./parse_lshw`

+ [Regression Potential]
+ smbios-noscan.patch was introduced to prevent ARM systems from locking up when lshw is being run. We are replacing this patch with cherry picked commit(8237f8ebb92ebf684c0e6715cc6c28a3b2bb93b8) from https://ezix.org/src/pkg/lshw which was released with lshw-B.02.18. Potentially this could bring back https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=740034 however upstream considers it fixed with the previously mentioned cherry pick.
