Subject: [PATCH v2 2/2] x86/apic: Update the 'apic=' description of setting APIC driver
Date: Mon, 4 Dec 2017 12:03:13 +0800	[thread overview]
Message-ID: <20171204040313.24824-2-douly.fnst@cn.fujitsu.com> (raw)
In-Reply-To: <20171204040313.24824-1-douly.fnst@cn.fujitsu.com>

There are two consumers of apic=: the APIC debug level and the low
level generic architecture code, but Linux just documented the first
one.

Append the second description.
