Subject: [PATCH v3 6/9] x86: move 32-bit vDSO padding from .data to .rodata
Date: Tue, 16 Jun 2009 14:55:26 +0200 [thread overview]
Message-ID: <1245156929-30395-7-git-send-email-ptesarik@suse.cz> (raw)
In-Reply-To: <1245156929-30395-1-git-send-email-ptesarik@suse.cz>
The padding is read-only after all, so there is no reason to put it
into a writable section.
