Shanker Donthineni f040e78cde arm64: errata: Mitigate TLBI errata on NVIDIA Olympus CPU
commit ec7216f92e upstream.

NVIDIA Olympus cores are affected by the TLBI completion issue tracked as
CVE-2025-10263. The existing ARM64_ERRATUM_4118414 handling already uses
ARM64_WORKAROUND_REPEAT_TLBI to issue an additional broadcast TLBI;DSB
sequence and ensure affected memory write effects are globally observed.

Add MIDR_NVIDIA_OLYMPUS to the repeat-TLBI match list so the same
mitigation is enabled on affected Olympus systems. Also document the
NVIDIA Olympus erratum in the arm64 silicon errata table and list it in
the Kconfig help text.

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.
