x86, dmi, debug: Log board name (when present) in dmesg/oops output
The "Type 2" SMBIOS record that contains Board Name is not
strictly required and may be absent in the SMBIOS on some
platforms.
( Please note that Type 2 is not listed in Table 3 in Sec 6.2
("Required Structures and Data") of the SMBIOS v2.7
Specification. )
Use the Manufacturer Name (aka System Vendor) name.
Print Board Name only when it is present.
Before the fix:
(i) dmesg output: DMI: /ProLiant DL380 G6, BIOS P62 01/29/2011
(ii) oops output: Pid: 2170, comm: bash Not tainted 2.6.38-rc4+ #3 /ProLiant DL380 G6
After the fix:
(i) dmesg output: DMI: HP ProLiant DL380 G6, BIOS P62 01/29/2011
(ii) oops output: Pid: 2278, comm: bash Not tainted 2.6.38-rc4+ #4 HP ProLiant DL380 G6
