Subject: [PATCH] x86/vsmp: Fix linker error when CONFIG_PROC_FS is not set
Date: Thu, 14 Jun 2012 18:43:08 +0300 [thread overview]
Message-ID: <1339688588-12674-1-git-send-email-ido@wizery.com> (raw)
In-Reply-To: <20120614105130.GB8683@gmail.com>
set_vsmp_pv_ops() references no_irq_affinity which is undeclared if
CONFIG_PROC_FS isn't set. Fix this by adding an ifdef around this
variable's access.
