* PCI: Move isa_dma_bridge_buggy out of asm/dma.hStafford Horne2022-07-221-6/+0
| | | | | | | | | | | | | | | | | | 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.

* microblaze: Remove noMMU codeMichal Simek2020-11-261-6/+0
| | | | | | | | | | | | | | | This configuration is obsolete and likely none is really using it. That's why remove it to simplify code. Note about CONFIG_MMU in hw_exception_handler.S is left intentionally for better comment understanding.
