Kristina Martsenko 98732d1b18 KVM: arm/arm64: fix HYP ID map extension to 52 bits Commit `fa2a8445b1` incorrectly masks the index of the HYP ID map pgd entry, causing a non-VHE kernel to hang during boot. This happens when VA_BITS=48 and the ID map text is in 52-bit physical memory. In this case we don't need an extra table level but need more entries in the top-level table, so we need to map into hyp_pgd and need to use __kvm_idmap_ptrs_per_pgd to mask in the extra bits. However, __create_hyp_mappings currently masks by PTRS_PER_PGD instead. Fix it so that we always use __kvm_idmap_ptrs_per_pgd for the HYP ID map. This ensures that we use the larger mask for the top-level ID map table when it has more entries. In all other cases, PTRS_PER_PGD is used as normal.

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.
