Subject: [PATCH] [2/8] x86: mce: Update X86_MCE description in x86/Kconfig
Date: Thu,  9 Jul 2009 00:31:38 +0200 (CEST)	[thread overview]
Message-ID: <20090708223138.E5EF41D035D@basil.firstfloor.org> (raw)
In-Reply-To: <200907091231.681564770@firstfloor.org>


- Clarify that this config controls thermal throttling
reporting too
- Clarify the types of errors reported by machine checks
- Drop references to ancient CPUs.
