Subject: [PATCH 1/3] x86, vdso32: undef CONFIG_OPTIMIZE_INLINING and CONFIG_X86_PPRO_FENCE
Date: Wed, 12 Mar 2014 23:51:18 +0100 [thread overview]
Message-ID: <1394664680-17799-2-git-send-email-stefani@seibold.net> (raw)
In-Reply-To: <1394664680-17799-1-git-send-email-stefani@seibold.net>
In case of a 32 bit vDSO build the CONFIG_OPTIMIZE_INLINING and
CONFIG_X86_PPRO_FENCE options will increase the size of the generated
vDSO not to fit in a page.
A #undef of this config options will solve this.
