cross-tree: phase out dma_zalloc_coherent()

2019-01-08T12:58:37Z

We already need to zero out memory for dma_alloc_coherent(), as such using dma_zalloc_coherent() is superflous. Phase it out. This change was generated with the following Coccinelle SmPL patch: @ replace_dma_zalloc_coherent @ expression dev, size, data, handle, flags; @@ -dma_zalloc_coherent(dev, size, handle, flags) +dma_alloc_coherent(dev, size, handle, flags) Suggested-by: Christoph Hellwig Signed-off-by: Luis Chamberlain [hch: re-ran the script on the latest tree] Signed-off-by: Christoph Hellwig

scsi: don't add scsi command result bytes

2018-06-26T16:27:07Z

Some drivers are ADDing the scsi command's result bytes instead of ORing them. While this can produce correct results it has unexpected side effects. Signed-off-by: Johannes Thumshirn Reviewed-by: Christoph Hellwig Reviewed-by: Bart Van Assche Signed-off-by: Martin K. Petersen

PCI: Remove includes of asm/pci-bridge.h

2016-02-05T22:29:28Z

Drivers should include asm/pci-bridge.h only when they need the arch- specific things provided there. Outside of the arch/ directories, the only drivers that actually need things provided by asm/pci-bridge.h are the powerpc RPA hotplug drivers in drivers/pci/hotplug/rpa*. Remove the includes of asm/pci-bridge.h from the other drivers, adding an include of linux/pci.h if necessary. Signed-off-by: Bjorn Helgaas

powerpc: Move Power Macintosh drivers to generic byteswappers

2015-03-23T03:29:40Z

ppc has special instruction forms to efficiently load and store values in non-native endianness. These can be accessed via the arch-specific {ld,st}_le{16,32}() inlines in arch/powerpc/include/asm/swab.h. However, gcc is perfectly capable of generating the byte-reversing load/store instructions when using the normal, generic cpu_to_le*() and le*_to_cpu() functions eaning the arch-specific functions don't have much point. Worse the "le" in the names of the arch specific functions is now misleading, because they always generate byte-reversing forms, but some ppc machines can now run a little-endian kernel. To start getting rid of the arch-specific forms, this patch removes them from all the old Power Macintosh drivers, replacing them with the generic byteswappers.

scsi: use 64-bit LUNs

2014-07-17T20:07:37Z

The SCSI standard defines 64-bit values for LUNs, and large arrays employing large or hierarchical LUN numbers become more and more common. So update the linux SCSI stack to use 64-bit LUN numbers.
