Merge tag 'powerpc-fixes' of git://github.com/paulusmack/linux into new/master
Five fixes for bugs that have crept in to the powerpc KVM implementations.
These are all small simple patches that only affect arch/powerpc/kvm.
They come from the series that Alex Graf put together but which was too
late for the 3.4 merge window.
* tag 'powerpc-fixes' of git://github.com/paulusmack/linux:
KVM: PPC: Book3S: PR: Fix preemption
KVM: PPC: Save/Restore CR over vcpu_run
KVM: PPC: Book3S HV: Save and restore CR in __kvmppc_vcore_entry
KVM: PPC: Book3S HV: Fix kvm_alloc_linear in case where no linears exist
KVM: PPC: Book3S: Compile fix for ppc32 in HIOR access code

+ * DMA-BUF/GEM Object references and lifetime overview:
+ *
+ * On the export the dma_buf holds a reference to the exporting GEM
+ * object. It takes this reference in handle_to_fd_ioctl, when it
+ * first calls .prime_export and stores the exporting GEM object in
+ * the dma_buf priv. This reference is released when the dma_buf
+ * object goes away in the driver .release function.
+ *
+ * On the import the importing GEM object holds a reference to the
+ * dma_buf (which in turn holds a ref to the exporting GEM object).
+ * It takes that reference in the fd_to_handle ioctl.
+ * It calls dma_buf_get, creates an attachment to it and stores the
+ * attachment in the GEM object. When this attachment is destroyed
+ * when the imported object is destroyed, we remove the attachment
+ * and drop the reference to the dma_buf.
+ *
+ * Thus the chain of references always flows in one direction
+ * (avoiding loops): importing_gem -> dmabuf -> exporting_gem
+ *
+ * Self-importing: if userspace is using PRIME as a replacement for flink
+ * then it will get a fd->handle request for a GEM object that it created.
+ * Drivers should detect this situation and return back the gem object
+ * from the dma-buf private.
