Subject: [PATCH 0/3] Move the ARCH_DMA_MINALIGN definition to asm/cache.h
Date: Tue, 13 Jun 2023 16:52:42 +0100 [thread overview]
Message-ID: <20230613155245.1228274-1-catalin.marinas@arm.com> (raw)
Hi,
The ARCH_KMALLOC_MINALIGN reduction series defines a generic
ARCH_DMA_MINALIGN in linux/cache.h:
https://lore.kernel.org/r/20230612153201.554742-2-catalin.marinas@arm.com/
Unfortunately, this causes a duplicate definition warning for
microblaze, powerpc (32-bit only) and sh as these architectures define
ARCH_DMA_MINALIGN in a different file than asm/cache.h. Move the macro
to asm/cache.h to avoid this issue and also bring them in line with the
other architectures.
Andrew, if the arch maintainers cc'ed are fine with such change, could
you please take these three patches together with the
ARCH_KMALLOC_MINALIGN series?
Thank you.

powerpc: Move the ARCH_DMA_MINALIGN definition to asm/cache.h
microblaze: Move the ARCH_{DMA,SLAB}_MINALIGN definitions to
asm/cache.h
sh: Move the ARCH_DMA_MINALIGN definition to asm/cache.h
