Subject: [PATCH v2 4/4] ARM: nommu: populate vectors page from paging_init
Date: Wed, 11 Apr 2012 15:30:39 +0100	[thread overview]
Message-ID: <1334154639-13869-5-git-send-email-will.deacon@arm.com> (raw)
In-Reply-To: <1334154639-13869-1-git-send-email-will.deacon@arm.com>

Commit 94e5a85b ("ARM: earlier initialization of vectors page") made it
the responsibility of paging_init to initialise the vectors page.

This patch adds a call to early_trap_init for the !CONFIG_MMU case,
placing the vectors at CONFIG_VECTORS_BASE.
