Subject: [PATCH v2 14/15] xen/arm: p2m: Replace flush_tlb_domain by p2m_flush_tlb
Date: Thu, 28 Jul 2016 15:20:19 +0100	[thread overview]
Message-ID: <1469715620-4670-15-git-send-email-julien.grall@arm.com> (raw)
In-Reply-To: <1469715620-4670-1-git-send-email-julien.grall@arm.com>

The function to flush the TLBs for a given p2m does not need to know about
the domain. So pass directly the p2m in parameter.

At the same time rename the function to p2m_flush_tlb to match the
parameter change.
