[for-6.2,v3,08/11] machine: Tweak the order of topology members in struct CpuTopology

Commit Message

Yanan Wang July 28, 2021, 3:48 a.m. UTC

Now that all the possible topology parameters are integrated in struct
CpuTopology, tweak the order of topology members to be "cpus/sockets/
dies/cores/threads/maxcpus" for readability and consistency. We also
tweak the comment by adding explanation of dies parameter.
