Breno Leitao bdf159a294 ACPI: APEI: GHES: add TAINT_MACHINE_CHECK on GHES panic path 
[ Upstream commit 4734c8b46b ]

When a GHES (Generic Hardware Error Source) triggers a panic, add the
TAINT_MACHINE_CHECK taint flag to the kernel. This explicitly marks the
kernel as tainted due to a machine check event, improving diagnostics
and post-mortem analysis. The taint is set with LOCKDEP_STILL_OK to
indicate lockdep remains valid.

At large scale deployment, this helps to quickly determine panics that
are coming due to hardware failures.
