Hello, This patchset introduces steal time accounting support for the VMware guest. The idea and implementation of guest steal time support is similar to KVM ones and it is based on steal clock. The steal clock is a per CPU structure in a shared memory between hypervisor and guest, initialized by each CPU through hypercall. Steal clock is got updated by the hypervisor and read by the guest. The patchset consists of 5 items: 1. x86/vmware: Make vmware_select_hypercall() __init Minor clean up. 2. x86/vmware: Remove vmware_sched_clock_setup() Preparation for the main patch. 3. x86/vmware: Steal time clock for VMware guest Core steal time support functionality. 4. x86/vmware: Enable steal time accounting Support for steal time accounting used by update_rq_clock(). 5. x86/vmware: Use bool type for vmw_sched_clock Minor clean up.
