| | | | | | | | | | | | | | | | | | find_first{,_zero}_bit is a more effective analogue of 'next' version if start == 0. This patch replaces 'next' with 'first' where things look trivial. Signed-off-by: Yury Norov <yury.norov@gmail.com> Tested-by: Wolfram Sang <wsa+renesas@sang-engineering.com>

To help with this maintenance let's start by moving sysctls to places where they actually belong. The proc sysctl maintainers do not want to know what sysctl knobs you wish to add for your own piece of code, we just care about the core logic. So move the sg-big-buff sysctl from kernel/sysctl.c to drivers/scsi/sg.c and use register_sysctl() to register the sysctl interface.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As stated in [1], dma_set_mask() with a 64-bit mask never fails if dev->dma_mask is non-NULL. So, if it fails, the 32 bits case will also fail for the same reason. Simplify code and remove some dead code accordingly. While at it, return the error code returned by dma_set_mask_and_coherent() instead of -1.

Use DMA API(scsi_dma_map/unmap) to map these memory during sending/receiving packet and return swiotlb bounce buffer dma address. In Isolation VM, swiotlb bounce buffer is marked to be visible to host and the swiotlb force mode is enabled.
