The Linux-internal Xlinuxenvcfg ISA extension is omitted from the riscv_isa_ext array because it has no DT binding and should not appear in /proc/cpuinfo. The logic added in commit625034abd5("riscv: add ISA extensions validation callback") assumes all extensions are included in riscv_isa_ext, and so riscv_resolve_isa() wrongly drops Xlinuxenvcfg from the final ISA string. Instead, accept such Linux-internal ISA extensions as if they have no validation callback.

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.
