Subject: powerpc/mm: Export mmu_kernel_ssize and mmu_linear_psize
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=8ca7a82f7b64ad29206daba7bdaf2f8766437243;p=deliverable%2Flinux.git

powerpc/mm: Export mmu_kernel_ssize and mmu_linear_psize

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 needs access to these.
