I don't understand:

$ git grep GETVCPU_INFO
arch/x86/kernel/cpu/vmware.c:51:#define VMWARE_CMD_GETVCPU_INFO  68
arch/x86/kernel/cpu/vmware.c:478:       VMWARE_CMD(GETVCPU_INFO, eax, ebx, ecx, edx);

so that's a VMWARE_CMD 68, at least the prefix says so.

And those two are *bits* in that eax which that hypercall returns.

Or are those two bits generic but defined in a vmware-specific
hypercall?

Hm.
