Subject: [RFC PATCH 3/3] ARM: syscall: wire up sys_migrate_pages.
Date: Wed, 12 Dec 2012 17:40:49 +0000	[thread overview]
Message-ID: <1355334049-10247-4-git-send-email-steve.capper@arm.com> (raw)
In-Reply-To: <1355334049-10247-1-git-send-email-steve.capper@arm.com>

For NUMA support, the sys_migrate_pages syscall is required by
userspace. This patch allocates #379 for this syscall and plumbs
it in.
