** Description changed:

  [Impact]
  
   * Add processor support from SMBIOS 3.6.0 in Jammy and Noble
     to enable new hardware in LTS release per SRU policy [1].
  
   * Backport of 1 relatively simple patch from dmidecode 3.6
     in Oracular to dmidecode 3.3 in Jammy and dmidecode 3.5 in Noble
  
  [Test Plan]
  
   * Check no regressions on current systems with SMBIOS < 3.6,
     i.e., no output changes in text and binary form.

   * Check for expected output on new systems with SMBIOS >= 3.6.

     1) Run "sudo dmidecode -t4"
     2) Observe that the "Thread Enabled" field is being reported

+ [Where problems could occur]
+ 
+  * The patch adds support for new bits/codes/strings,
+    so there are no changes expected for the old spec support.
+ 
+  * The new field (Thread Enabled) is added in a specific condition
+    and should not impact systems without support to it.
+ 
+  * If the current dmidecode is being used on systems that support
+    the new bits, users will see a different output, and this might 
+    break some text parsers if they are strictly programmed. Using the
+    binary output is recommended in these cases.
