Subject: [PATCH v3 05/16] powerpc/mm: Export mmu_kernel_ssize and mmu_linear_psize
Date: Tue, 7 Oct 2014 21:48:11 +1100 [thread overview]
Message-ID: <1412678902-18672-6-git-send-email-mikey@neuling.org> (raw)
In-Reply-To: <1412678902-18672-1-git-send-email-mikey@neuling.org>
From: Ian Munsie <imunsie@au1.ibm.com>
Export mmu_kernel_ssize and mmu_linear_psize. These are needed by the cxl
driver which has it's own MMU. To setup the MMU cxl need access to these.
