Although the idmap section of KVM can only be at most 4kB and must be aligned on a 4kB boundary, the rest of the code expects it to be page aligned. Things get messy when tearing down the HYP page tables when PAGE_SIZE is 64K, and the idmap section isn't 64K aligned. Let's fix this by computing aligned boundaries that the HYP code will use.

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.
