Subject: [PATCH v2 3/3] x86/fred: Remove kernel log message when initializing exceptions
Date: Wed, 25 Mar 2026 16:01:49 -0700 [thread overview]
Message-ID: <20260325230151.1898287-4-hpa@zytor.com> (raw)
In-Reply-To: <20260325230151.1898287-1-hpa@zytor.com>
From: Sohil Mehta <sohil.mehta@intel.com>
When FRED is enabled, its initialization message is printed for every
CPU during boot as well as during suspend-resume. This debug message can
be noisy and it isn't very useful unless someone is debugging FRED
itself.
As FRED is enabled by default, remove the log message as mentioned in
the code comment.
