Ampere Altra Max Processor SMBIOS sees only 64 cores

[armfucker777]

Hi, all!
When i boot to Ubuntu 20.04 aarch64 dmi and smbios sees all 128 cores.
When i boot to Archlinux 5.19.8-1 dmi sees all 128 cores, but htop and lshw sees only 64 cores.

I think maybe this forum thread is related to the problem, but the patch file is not attached to it.

Tell me how to fix this problem?
