Subject: [PATCH v2 06/10] ARM: p2v: drop redundant 'type' argument from __pv_stub
Date: Mon, 21 Sep 2020 17:41:13 +0200	[thread overview]
Message-ID: <20200921154117.757-7-ardb@kernel.org> (raw)
In-Reply-To: <20200921154117.757-1-ardb@kernel.org>

We always pass the same value for 'type' so pull it into the __pv_stub
macro itself.
