Subject: [PATCH v8 02/14] MIPS: Fix set_uncached_handler for ebase in XKPHYS
Date: Fri, 16 Feb 2024 18:42:11 +0100	[thread overview]
Message-ID: <20240216174227.409400-3-gregory.clement@bootlin.com> (raw)
In-Reply-To: <20240216174227.409400-1-gregory.clement@bootlin.com>

From: Jiaxun Yang <jiaxun.yang@flygoat.com>

ebase might reside in XKPHYS if memblock is unable to allocate memory
within the KSEG0 physical range.

To map EBASE into uncached space, we convert it back to its physical
address and utilize the new CKSEG1ADDR_OR_64BIT helper for mapping.
