Remove dependencies on HAS_DMA where a Kconfig symbol depends on another symbol that implies HAS_DMA, and, optionally, on "|| COMPILE_TEST". In most cases this other symbol is an architecture or platform specific symbol, or PCI. Generic symbols and drivers without platform dependencies keep their dependencies on HAS_DMA, to prevent compiling subsystems or drivers that cannot work anyway. This simplifies the dependencies, and allows to improve compile-testing.

2018-03-13scsi: core: Make SCSI Status CONDITION MET equivalent to GOODDouglas Gilbert2-0/+13
The SCSI PRE-FETCH (10 or 16) command is present both on hard disks and some SSDs. It is useful when the address of the next block(s) to be read is known but it is not following the LBA of the current READ (so read-ahead won't help). It returns two "good" SCSI Status values. If the requested blocks have fitted (or will most likely fit (when the IMMED bit is set)) into the disk's cache, it returns CONDITION MET. If it didn't (or will not) fit then it returns GOOD status. The goal of this patch is to stop the SCSI subsystem treating the CONDITION MET SCSI status as an error. The current state makes the PRE-FETCH command effectively unusable via pass-throughs.

2018-03-13scsi: lpfc: Memory allocation error during driver start-up on power8James Smart4-11/+21
The driver fails to allocate command buffers in the routine lpfc_new_scsi_buf_s4 There is an inconsistency between lpfc_mem_alloc(), where the phba->lpfc_sg_dma_buf_pool is created, and lpfc_new_scsi_buf_s4(), when we allocate a buffer from the pool and check the alignment. The alignment should be on a page boundary, based on LPFC_SLI3_BG_ENABLED in sli3_options, for both cases. Fix by explicitly tracking sli4 vs sli3 and BG options. The result is that phba->cfg_sg_dma_buf_size is now set correctly for SLI-4.
