 should be bounce buffer memory GPA plus with shared_gpa_boundary
 reported by CPUID.
 
-Change since V1:
-       - Introduce x86_set_memory_enc static call and so platforms can
-         override __set_memory_enc_dec() with their implementation
-       - Introduce sev_es_ghcb_hv_call_simple() and share code
-         between SEV and Hyper-V code.
-       - Not remap monitor pages in the non-SNP isolation VM
-       - Make swiotlb_init_io_tlb_mem() return error code and return
-         error when dma_map_decrypted() fails.
-
-Change since RFC V4:
-       - Introduce dma map decrypted function to remap bounce buffer
-          and provide dma map decrypted ops for platform to hook callback.        
-       - Split swiotlb and dma map decrypted change into two patches
-       - Replace vstart with vaddr in swiotlb changes.
-
-Change since RFC v3:
-       - Add interface set_memory_decrypted_map() to decrypt memory and
-         map bounce buffer in extra address space
-       - Remove swiotlb remap function and store the remap address
-         returned by set_memory_decrypted_map() in swiotlb mem data structure.
-       - Introduce hv_set_mem_enc() to make code more readable in the __set_memory_enc_dec().
-
-Change since RFC v2:
-       - Remove not UIO driver in Isolation VM patch
-       - Use vmap_pfn() to replace ioremap_page_range function in
-       order to avoid exposing symbol ioremap_page_range() and
-       ioremap_page_range()
-       - Call hv set mem host visibility hvcall in set_memory_encrypted/decrypted()
-       - Enable swiotlb force mode instead of adding Hyper-V dma map/unmap hook
-       - Fix code style
