Subject: kvm: svm: de-allocate svm_cpu_data for all cpus in svm_cpu_uninit()
X-Git-Url: http://git.osdn.net/view?a=commitdiff_plain;h=a2b2d4bf5076832339762556b816eec58ca38f77;p=uclinux-h8%2Flinux.git

kvm: svm: de-allocate svm_cpu_data for all cpus in svm_cpu_uninit()

The cpu arg for svm_cpu_uninit() was previously ignored resulting in the
per cpu structure svm_cpu_data not being de-allocated for all cpus.
