Subject: [PATCH AUTOSEL 4.14 55/72] mips: MAAR: Use more precise address mask
Date: Mon, 8 Jun 2020 19:24:43 -0400 [thread overview]
Message-ID: <20200608232500.3369581-55-sashal@kernel.org> (raw)
In-Reply-To: <20200608232500.3369581-1-sashal@kernel.org>
From: Serge Semin <Sergey.Semin@baikalelectronics.ru>
[ Upstream commit bbb5946eb545fab8ad8f46bce8a803e1c0c39d47 ]
Indeed according to the MIPS32 Privileged Resource Architecgture the MAAR
pair register address field either takes [12:31] bits for non-XPA systems
and [12:55] otherwise. In any case the current address mask is just
wrong for 64-bit and 32-bits XPA chips. So lets extend it to 59-bits
of physical address value. This shall cover the 64-bits architecture and
systems with XPA enabled, and won't cause any problem for non-XPA 32-bit
systems, since address values exceeding the architecture specific MAAR
mask will be just truncated with setting zeros in the unsupported upper
bits.
