Subject: [RFC PATCHv3 03/11] percpu: use VMALLOC_TOTAL instead of VMALLOC_END - VMALLOC_START
Date: Thu,  2 Jan 2014 13:53:21 -0800	[thread overview]
Message-ID: <1388699609-18214-4-git-send-email-lauraa@codeaurora.org> (raw)
In-Reply-To: <1388699609-18214-1-git-send-email-lauraa@codeaurora.org>

vmalloc already gives a useful macro to calculate the total vmalloc
size. Use it.
