Subject: [PATCH 1/2] powerpc: Add generic PAGE_SIZE config symbols
Date: Thu, 5 May 2022 22:51:22 +1000 [thread overview]
Message-ID: <20220505125123.2088143-1-mpe@ellerman.id.au> (raw)
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.
