From abb4970ac33514c84b143516583eaf8cc47abd67 Mon Sep 17 00:00:00 2001 From: Stafford Horne Date: Sat, 23 Jul 2022 06:49:42 +0900 Subject: PCI: Move isa_dma_bridge_buggy out of asm/dma.h The isa_dma_bridge_buggy symbol is only used for x86_32, and only x86_32 platforms or quirks ever set it. Add a new linux/isa-dma.h header that #defines isa_dma_bridge_buggy to 0 except on x86_32, where we keep it as a variable, and remove all the arch- specific definitions.
