RH-Commit: [1/1] ee6d9bb6dfa0fb2625915947072cb91a0926c4ec

Since table type 4 of SMBIOS version 2.6 is shorter than 3.0, the
|
|
|
ed5979 |
strings which follow immediately after the struct fields have been
|
|
|
ed5979 |
overwritten by unconditional filling of later fields such as core_count2.
|
|
|
ed5979 |
Make these fields dependent on the SMBIOS version.
|
|
|

|

Fixes: 05e27d74c7 ("hw/smbios: add core_count2 to smbios table type 4")
