Commit5995a68"xen/privcmd: Add support for Linux 64KB page granularity" did not go far enough to support 64KB in mmap_batch_fn. The variable 'nr' is the number of 4KB chunk to map. However, when Linux is using 64KB page granularity the array of pages (vma->vm_private_data) contain one page per 64KB. Fix it by incrementing st->index correctly. Furthermore, st->va is not correctly incremented as PAGE_SIZE != XEN_PAGE_SIZE.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
