Subject: smbios: Default all values to zero.
X-Git-Tag: rel-1.7.5-rc1~33
X-Git-Url: http://xenbits.xensource.com/gitweb?a=commitdiff_plain;h=9b9c2403f9e990397c2757a922a4022cfa0c8155;p=seabios.git

smbios: Default all values to zero.

Make sure to initialize the entire smbios area to zero so that any
field not explicitly initialized does not have random values.  (It was
found that the memory_error_information_handle field in smbios_type_17
was not being set.)
