Date: Thu, 5 May 2022 22:51:22 +1000 From: Michael Ellerman <mpe@...erman.id.au> To: <linuxppc-dev@...ts.ozlabs.org> Cc: <linux-kernel@...r.kernel.org> Subject: [PATCH 1/2] powerpc: Add generic PAGE_SIZE config symbols Other arches (sh, mips, hexagon) use standard names for PAGE_SIZE related config symbols. Add matching symbols for powerpc, which are enabled by default but depend on our architecture specific PAGE_SIZE symbols. This allows generic/driver code to express dependencies on the PAGE_SIZE without needing to refer to architecture specific config symbols.
