Clang warns (or errors with CONFIG_WERROR=y / W=e):
arch/arm64/kvm/hyp/pgtable.c:757:2: error: label at end of compound statement is a C23 extension [-Werror,-Wc23-extensions]
757 | }
| ^
With older versions of clang (15 and older) and GCC (at least the minimum
supported, 8.1), this is an unconditional hard error:
arch/arm64/kvm/hyp/pgtable.c: In function 'kvm_pgtable_stage2_pte_prot':
arch/arm64/kvm/hyp/pgtable.c:756:2: error: label at end of compound statement
default:
^~~~~~~
arch/arm64/kvm/hyp/pgtable.c:756:10: error: label at end of compound statement: expected statement
default:
^
;
Add a break statement to this default case to clear up the error/warning.

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 reStructuredText 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.
