In kvmppc_unmap_free_pte() in book3s_64_mmu_radix.c, we use the non-constant value PTE_INDEX_SIZE to clear a PTE page. We can instead use the constant RADIX_PTE_INDEX_SIZE, because we know this code will only be running when the Radix MMU is active. Note that we already use RADIX_PTE_INDEX_SIZE for the allocation of kvm_pte_cache.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
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.
