Subject: [PATCH 1/9] ARM: Do early I/O mapping if spinlock debugging is enabled
Date: Wed, 28 Jan 2009 10:23:05 -0800 [thread overview]
Message-ID: <20090128182305.21007.62781.stgit@localhost> (raw)
In-Reply-To: <20090128181931.21007.73744.stgit@localhost>
From: Juha Yrjola <juha.yrjola@solidboot.com>
At least on OMAP, sched_clock() requires the I/O maps to be initialized.
Spinlock debugging invokes sched_clock() very early.
