RFR: 8259563: The CPU model name is printed multiple times when using -Xlog:os+cpu

[Wang Xue]

Hi all,

The CPU model name will be printed multiple times if the platform only has model name but no flags (such as mips) when using -Xlog:os+cpu. "model_name_printed" should be initialized to "false" before the loop. Please review this trivial change.

Thanks,
Wang Xue
