Lai Jiangshan 5b22bbe717 KVM: X86: Change the type of access u32 to u64 ... Change the type of access u32 to u64 for FNAME(walk_addr) and ->gva_to_gpa(). The kinds of accesses are usually combinations of UWX, and VMX/SVM's nested paging adds a new factor of access: is it an access for a guest page table or for a final guest physical address. And SMAP relies a factor for supervisor access: explicit or implicit. So @access in FNAME(walk_addr) and ->gva_to_gpa() is better to include all these information to do the walk. Although @access(u32) has enough bits to encode all the kinds, this patch extends it to u64: o Extra bits will be in the higher 32 bits, so that we can easily obtain the traditional access mode (UWX) by converting it to u32. o Reuse the value for the access kind defined by SVM's nested paging (PFERR_GUEST_FINAL_MASK and PFERR_GUEST_PAGE_MASK) as @error_code in kvm_handle_page_fault().
