   Hi all,
   
     please review the obsoletion of the unused `ProcessDistributionStride` option. It controlled how threads were distributed across "boards" on Solaris. Solaris support has been removed in JDK 15, so this option is not needed/used either.
   
   Testing: local compilation, grepping sources, testing the option to give the expected warning message
   
   Thanks,
     Thomas

   Hi all,
   
     please review making the flag `NUMAPageScanRate` obsolete.
   
   This option controlled some fairly esoteric performance capability for Solaris; Solaris support has been removed in JDK 15, and the last remaining reference to the option (which was a no-op) in JDK 22.
   
   Testing: local compilation, grepping sources, starting the VM with that option to see that the message shows up.
   
   Thanks,
     Thomas

   Hi all,
   
     please review this change to obsolete the unused flag GCLockerEdenExpansionPercent. Please also review the CSR.
   
   Testing: local compilation, grepping sources for occurrences
   
   Thanks,
     Thomas
