Linux kernel source tree
faf000397e
The PUD and PMD are folded into PGD when the following options are
enabled. In that case, PUD_SHIFT is equal to PMD_SHIFT and we fail
to build with the indicated errors:
CONFIG_ARM64_VA_BITS_42=y
CONFIG_ARM64_PAGE_SHIFT=16
CONFIG_PGTABLE_LEVELS=3
arch/arm64/kvm/mmu.c: In function ‘user_mem_abort’:
arch/arm64/kvm/mmu.c:798:2: error: duplicate case value
case PMD_SHIFT:
^~~~
arch/arm64/kvm/mmu.c:791:2: note: previously used here
case PUD_SHIFT:
^~~~
This fixes the issue by skipping the check on PUD huge page when PUD
and PMD are folded into PGD.

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.
