[PATCH v10 6/8] x86/vmware: Correct macro names
Posted by Alexey Makhalov 1 year, 8 months ago
VCPU_RESERVED and LEGACY_X2APIC are not VMware hypercall commands.
These are bits in return value of VMWARE_CMD_GETVCPU_INFO command.
Change VMWARE_CMD_ prefix to GETVCPU_INFO_ one. And move bit-shift
operation to the macro body.
