Subject: [PATCH] kbuild: ignore cache modifiers for generating the tags files
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

With this patch I'm able to find the definition of _xmit_lock defined in
include/linux/netdevice.h as follows:

	struct net_device {
		...
		spinlock_t _xmit_lock ____cacheline_aligned_in_smp;
	}

Otherwise this counts as definition of ____cacheline_aligned_in_smp.
