Subject: [PATCH v3 03/22] MIPS: spaces: Define a couple of handy macros
Date: Fri, 1 Dec 2023 12:14:46 +0100 [thread overview]
Message-ID: <20231201111512.803120-4-gregory.clement@bootlin.com> (raw)
In-Reply-To: <20231201111512.803120-1-gregory.clement@bootlin.com>
From: Jiaxun Yang <jiaxun.yang@flygoat.com>
KSEGX_SIZE is defined to size of each KSEG segment.
TO_CAC and TO_UNCAC are brought to 32bit builds as well,
TO_PHYS remains to be 64bit only as we want people to
use __pa to avoid mixup compat address space.
