Subject: [PATCH 07/13] arch: remove the ARCH_PHYS_ADDR_T_64BIT config symbol
Date: Wed, 25 Apr 2018 07:15:33 +0200 [thread overview]
Message-ID: <20180425051539.1989-8-hch@lst.de> (raw)
In-Reply-To: <20180425051539.1989-1-hch@lst.de>
Instead select the PHYS_ADDR_T_64BIT for 32-bit architectures that need a
64-bit phys_addr_t type directly.
