13a34e067e KVM: remove garbage arg to *hardware_{en,dis}able 
In the beggining was on_each_cpu(), which required an unused argument to
kvm_arch_ops.hardware_{en,dis}able, but this was soon forgotten.

Remove unnecessary arguments that stem from this.

0865e636ae KVM: static inline empty kvm_arch functions 
Using static inline is going to save few bytes and cycles.
For example on powerpc, the difference is 700 B after stripping.
(5 kB before)

This patch also deals with two overlooked empty functions:
kvm_arch_flush_shadow was not removed from arch/mips/kvm/mips.c
  2df72e9bc KVM: split kvm_arch_flush_shadow
and kvm_arch_sched_in never made it into arch/ia64/kvm/kvm-ia64.c.
  e790d9ef6 KVM: add kvm_arch_sched_in

e790d9ef64 KVM: add kvm_arch_sched_in 
Introduce preempt notifiers for architecture specific code.
Advantage over creating a new notifier in every arch is slightly simpler
code and guaranteed call order with respect to kvm_sched_in.

8533ce7271 These are the x86, MIPS and s390 changes; PPC and ARM will come in a 
few days.
 
 MIPS and s390 have little going on this release; just bugfixes, some
 small, some larger.
 
 The highlights for x86 are nested VMX improvements (Jan Kiszka), optimizations
 for old processor (up to Nehalem, by me and Bandan Das), and a lot of x86
 emulator bugfixes (Nadav Amit).
 
 Stephen Rothwell reported a trivial conflict with the tracing branch.

784aa3d7fb KVM: Rename and add argument to check_extension 
In preparation to make the check_extension function available to VM scope
we add a struct kvm * argument to the function header and rename the function
accordingly. It will still be called from the /dev/kvm fd, but with a NULL
argument for struct kvm *.
