s390/mm: Remove sev_active() function

2019-08-09T12:52:11Z

All references to sev_active() were moved to arch/x86 so we don't need to define it for s390 anymore.

x86, s390/mm: Move sme_active() and sme_me_mask to x86-specific header

2019-08-09T12:52:08Z

Now that generic code doesn't reference them, move sme_active() and sme_me_mask to x86's . Also remove the export for sme_active() since it's only used in files that won't be built as modules. sme_me_mask on the other hand is used in arch/x86/kvm/svm.c (via __sme_set() and __psp_pa()) which can be built as a module so its export needs to stay.

s390/mm: force swiotlb for protected virtualization

2019-06-15T10:24:51Z

On s390, protected virtualization guests have to use bounced I/O buffers. That requires some plumbing. Let us make sure, any device that uses DMA API with direct ops correctly is spared from the problems, that a hypervisor attempting I/O to a non-shared page would bring.
