32-bit architectures which expect 8-byte alignment for 8-byte integers and need 64-bit DMA addresses (arc, arm, mips, ppc) had their struct page inadvertently expanded in 2019.FWIW, ARC doesn't require 8 byte alignment for 8 byte integers. This is only needed for 8-byte atomics due to the requirements of LLOCKD/SCOND instructions.
Ah, like x86? OK, great, I'll drop your arch from the list of affected. Thanks! _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel
