PM / Hibernate: Make default image size depend on total RAM size
The default hibernation image size is currently hard coded and euqal to 500 MB, which is not a reasonable default on many contemporary systems. Make it equal 2/5 of the total RAM size (this is slightly below the maximum, i.e. 1/2 of the total RAM size, and seems to be generally suitable). Signed-off-by: Rafael J. Wysocki <rjw@sisk.pl> Tested-by: M. Vefa Bicakci <bicave@superonline.com>
