[ Upstream commit d7ce7e3a84642aadf7c4787f7ec4f58eb163d129 ] Set TAINT_MACHINE_CHECK when SError or Synchronous External Abort (SEA) interrupts trigger a panic to flag potential hardware faults. This tainting mechanism aids in debugging and enables correlation of hardware-related crashes in large-scale deployments. This change aligns with similar patches[1] that mark machine check events when the system crashes due to hardware errors.

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.
