Subject: [PATCH] dma-mapping: fix filename references
References: bsc#1156419,jsc#SLE-8281
Git-commit: 392e879a445008e8e96b872dabaaf5b1eca58729
Patch-mainline: v5.4-rc1
After commit cf65a0f6f6ff ("dma-mapping: move all DMA mapping code to
kernel/dma") some of the files are referring to outdated information,
i.e. old file names of DMA mapping sources. Fix it here.
Note, the lines with "Glue code for..." have been removed completely.

===========================================
Multiple x86-64 PCI-DMA mapping implementations exist, for example:
- 1. <lib/dma-direct.c>: use no hardware/software IOMMU at all
+ 1. <kernel/dma/direct.c>: use no hardware/software IOMMU at all
(e.g. because you have < 3 GB memory).
