2019-02-08scsi: ata: Use unsigned int for cmd's type in ioctls in scsi_host_templateNathan Chancellor
Clang warns several times in the scsi subsystem (trimmed for brevity): drivers/scsi/hpsa.c:6209:7: warning: overflow converting case value to switch condition type (2147762695 to 18446744071562347015) [-Wswitch] case CCISS_GETBUSTYPES: ^ drivers/scsi/hpsa.c:6208:7: warning: overflow converting case value to switch condition type (2147762694 to 18446744071562347014) [-Wswitch] case CCISS_GETHEARTBEAT: ^ The root cause is that the _IOC macro can generate really large numbers, which don't fit into type 'int', which is used for the cmd parameter in the ioctls in scsi_host_template. My research into how GCC and Clang are handling this at a low level didn't prove fruitful. However, looking at the rest of the kernel tree, all ioctls use an 'unsigned int' for the cmd parameter, which will fit all of the _IOC values in the scsi/ata subsystems. Make that change because none of the ioctls expect a negative value for any command, it brings the ioctls inline with the reset of the kernel, and it removes ambiguity, which is never good when dealing with compilers.

2019-01-29scsi: remove unneeded header search pathsMasahiro Yamada
I was able to build without these extra header search paths. Especially, the header search path -I. in kernel Makefiles is always suspicious; it allows the compiler to search for headers in the top of $(srctree), where obviously no header file exists.

2019-01-22scsi: communicate max segment size to the DMA mapping codeChristoph Hellwig
When a host driver sets a maximum segment size we should not only propagate that setting to the block layer, which can merge segments, but also to the DMA mapping layer which can merge segments as well.

Pull SCSI updates from James Bottomley: "This is mostly updates of the usual drivers: UFS, esp_scsi, NCR5380, qla2xxx, lpfc, libsas, hisi_sas. In addition there's a set of mostly small updates to the target subsystem a set of conversions to the generic DMA API, which do have some potential for issues in the older drivers but we'll handle those as case by case fixes. A new myrs driver for the DAC960/mylex raid controllers to replace the block based DAC960 which is also being removed by Jens in this merge window. Plus the usual slew of trivial changes" [ "myrs" stands for "MYlex Raid Scsi". Obviously. Silly of me to even wonder. There's also a "myrb" driver, where the 'b' stands for 'block'.
