x86/pci: Clean up usage of X86_DEV_DMA_OPS

2019-04-24T11:12:05Z

We have supported per-device dma_map_ops in generic code for a long time, and this symbol just guards the inclusion of the dma_map_ops registry used for vmd. Stop enabling it for anything but vmd. No change in functionality intended.

misc: mic/scif: mark expected switch fall-through

2019-02-27T15:00:20Z

In preparation to enabling -Wimplicit-fallthrough, mark switch cases where we are expecting to fall through. This patch fixes the following warning: drivers/misc/mic/scif/scif_rma.c: In function ‘scif_unregister_window’: drivers/misc/mic/scif/scif_rma.c:665:12: warning: this statement may fall through [-Wimplicit-fallthrough=] send_msg = true; ~~~~~~~~~^~~~~~ drivers/misc/mic/scif/scif_rma.c:668:2: note: here case OP_IN_PROGRESS: ^~~~ Warning level 3 was used: -Wimplicit-fallthrough=3 Notice that, in this particular case, the code comment is modified in accordance with what GCC is expecting to find. This patch is part of the ongoing efforts to enable -Wimplicit-fallthrough. Signed-off-by: Gustavo A. R. Silva Signed-off-by: Greg Kroah-Hartman

mic: vop: Allow building on more systems

2019-02-26T11:54:55Z

VOP_BUS does not actually depend on x86-64 or PCI or X86_DEV_DMA_OPS. The dependency on X86_DEV_DMA_OPS has been unnecessary since commit 5657933dbb6e25fe ("treewide: Move dma_ops from struct dev_archdata into struct device"). Signed-off-by: Vincent Whitchurch Signed-off-by: Greg Kroah-Hartman

mic: Rename ioremap pointer to remap

2019-02-26T11:54:55Z

Some architectures (like MIPS) implement ioremap as a macro, and this leads to conflicts with the ioremap function pointer in various mic structures. drivers/misc/mic/vop/vop_vringh.c: In function 'vop_virtio_init_post': drivers/misc/mic/vop/vop_vringh.c:86:13: error: macro "ioremap" passed 3 arguments, but takes just 2 Rename ioremap to remap to fix this. Likewise for iounmap. Signed-off-by: Vincent Whitchurch Signed-off-by: Greg Kroah-Hartman
