Subject: [PATCH 09/13] PCI: remove CONFIG_PCI_BUS_ADDR_T_64BIT
Date: Wed, 25 Apr 2018 07:15:35 +0200 [thread overview]
Message-ID: <20180425051539.1989-10-hch@lst.de> (raw)
In-Reply-To: <20180425051539.1989-1-hch@lst.de>
This symbol is now always identical to CONFIG_ARCH_DMA_ADDR_T_64BIT, so
remove it.
Signed-off-by: Christoph Hellwig <hch@lst.de>
Acked-by: Bjorn Helgaas <bhelgaas@google.com>
