I would prefer if we retained the current test structure and swap
 the x86_64 with amd64, as amd64 is the os.arch on which the test will be run

Change 

 80 /* @test
 81  * @summary Testing NVRAM mapped byte buffer support
 82  * @run main/manual PmemTest
 83  * @requires (os.family == "linux")
 84  * @requires (os.arch == "x86_64")
 85  */
 86 
 87 /* @test
 88  * @summary Testing NVRAM mapped byte buffer support
 89  * @run main/manual PmemTest
 90  * @requires (os.family == "linux")
 91  * @requires ((os.arch == "amd64")|(os.arch == "aarch64")|(os.arch == "ppc64le"))
 92  * @ignore The test described here is currently disabled on systems that are not
 93  * x64-based and lack an external NVRAM memory device. In order to re-enable the
 94  * test, you will need to mount the NVRAM device, which will typically appear as
 95  * /dev/pmem0, to the directory /mnt/pmem. Once that is done, you can follow the
 96  * instructions above to create a test directory and remove the ignore tag.

To  the preferred change i.e. to swap the x86_64 and amd64 and to use
