On VF610 series there are no regulators used, and now whether the

And this patch will solve this issue.

Hi,
Unaligned stores take alignment exceptions on POWER7 running in

prevents unaligned stores. It is replaced by the VMX memcpy at boot.
Is this any faster than the generic version?

Since kvmppc_hv_find_lock_hpte() is called from both virtmode and

Suppose the following scene:

If on cpuM, vcpu_A_1 holds bitlock X (HPTE_V_HVLOCK), then is switched out,
