Add an arm64 version of get_cpuid(), which is used for various annotation and headers - for example, I now get the CPUID in "perf report --header", as shown in this snippet: # hostname : ubuntu # os release : 5.5.0-rc1-dirty # perf version : 5.5.rc1.gbf8a13dc9851 # arch : aarch64 # nrcpus online : 96 # nrcpus avail : 96 # cpuid : 0x00000000480fd010 Since much of the code to read the MIDR is already in get_cpuid_str(), factor out this code. Tester notes: I tested this patch on my new ARM64 Kunpeng 920 server. [root@node1 zsk]# ./perf --version perf version 5.6.rc1.g2cdb955b7252 Both perf list and perf stat can work.
