scsi: a2091: Convert m68k WD33C93 drivers to DMA API

2022-07-07T21:01:22+00:00

Use dma_map_single() for a2091 driver (leave bounce buffer logic unchanged). Use dma_set_mask_and_coherent() to avoid explicit cache flushes. Compile-tested only.

scsi: wd33c93: Move the SCSI pointer to private command data

2022-02-23T02:11:07+00:00

Set .cmd_size in the SCSI host template instead of using the SCSI pointer from struct scsi_cmnd. This patch prepares for removal of the SCSI pointer from struct scsi_cmnd.

scsi: Remove drivers/scsi/scsi.h

2022-02-23T02:11:02+00:00

The following two header files have the same file name: include/scsi/scsi.h and drivers/scsi/scsi.h. This is confusing. Remove the latter since the following note was added in drivers/scsi/scsi.h in 2004: "NOTE: this file only contains compatibility glue for old drivers. All these wrappers will be removed sooner or later. For new code please use the interfaces declared in the headers in include/scsi/" Link: https://lore.kernel.org/r/20220218195117.25689-7-bvanassche@acm.org Cc: Christoph Hellwig Cc: Ming Lei Reviewed-by: Hannes Reinecke Reviewed-by: Himanshu Madhani Reviewed-by: Johannes Thumshirn Acked-by: Greg Kroah-Hartman Signed-off-by: Bart Van Assche Signed-off-by: Martin K.

mm: don't include asm/pgtable.h if linux/mm.h is already included

2020-06-09T16:39:13+00:00

Patch series "mm: consolidate definitions of page table accessors", v2. The low level page table accessors (pXY_index(), pXY_offset()) are duplicated across all architectures and sometimes more than once. For instance, we have 31 definition of pgd_offset() for 25 supported architectures. Most of these definitions are actually identical and typically it boils down to, e.g. static inline unsigned long pmd_index(unsigned long address) { return (address >> PMD_SHIFT) & (PTRS_PER_PMD - 1); } static inline pmd_t *pmd_offset(pud_t *pud, unsigned long address) { return (pmd_t *)pud_page_vaddr(*pud) + pmd_index(address); } These definitions can be shared among 90% of the arches provided XYZ_SHIFT, PTRS_PER_XYZ and xyz_page_vaddr() are defined. For architectures that really need a custom version there is always possibility to override the generic version with the usual ifdefs magic. These patches introduce include/linux/pgtable.h that replaces include/asm-generic/pgtable.h and add the definitions of the page table accessors to the new header. This patch (of 12): The linux/mm.h header includes to allow inlining of the functions involving page table manipulations, e.g. pte_alloc() and pmd_alloc(). So, there is no point to explicitly include in the files that include . The include statements in such cases are remove with a simple loop: for f in $(git grep -l "include ") ; do sed -i -e '/include / d' $f done Signed-off-by: Mike Rapoport Signed-off-by: Andrew Morton Cc: Arnd Bergmann Cc: Borislav Petkov Cc: Brian Cain Cc: Catalin Marinas Cc: Chris Zankel Cc: "David S.

scsi: remove the use_clustering flag

2018-12-19T04:19:21+00:00

The same effects can be achieved by setting the dma_boundary to PAGE_SIZE - 1 and the max_segment_size to PAGE_SIZE, so shift those settings into the drivers. Note that in many cases the setting might be bogus, but this keeps the status quo. [mkp: fix myrs and myrb] Signed-off-by: Christoph Hellwig Signed-off-by: Martin K. Petersen

scsi: drop bus reset for wd33c93-compatible boards

The bus reset function is just a wrapper calling host reset under the host lock. So move taking of the host lock into the host reset function and drop bus reset. Signed-off-by: Hannes Reinecke Reviewed-by: Christoph Hellwig Reviewed-by: Johannes Thumshirn Signed-off-by: Martin K. Petersen

zorro: ZTWO_VADDR() should return "void __iomem *"

2013-11-26T10:09:07+00:00

ZTWO_VADDR() converts from physical to virtual I/O addresses, so it should return "void __iomem *" instead of "unsigned long". This allows to drop several casts, but requires adding a few casts to accomodate legacy driver frameworks that store "unsigned long" I/O addresses. Signed-off-by: Geert Uytterhoeven
