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.
