sg_mark_end() overwrites the page_link information, but all users want __sg_mark_end() behaviour where we just set the end bit. That is the most natural way to use the sg list, since you'll fill it in and then mark the end point. So change sg_mark_end() to only set the termination bit. Add a sg_magic debug check as well, and clear a chain pointer if it is set. Signed-off-by: NJens Axboe <jens.axboe@oracle.com>

a) for type B we should _not_ iounmap() acb->pmu; it's not ioremapped. b) for type B we should iounmap() two regions we _do_ ioremap. c) if ioremap() fails, we need to bail out (and clean up).

Use of ptrdiff_t in places like - if (!access_ok(VERIFY_WRITE, u_tmp->rx_buf, u_tmp->len)) + if (!access_ok(VERIFY_WRITE, (u8 __user *) + (ptrdiff_t) u_tmp->rx_buf, + u_tmp->len)) is wrong; for one thing, it's a bad C (it's what uintptr_t is for; in general we are not even promised that ptrdiff_t is large enough to hold a pointer, just enough to hold a difference between two pointers within the same object). For another, it confuses the fsck out of sparse. Use unsigned long or uintptr_t instead. There are several places misusing ptrdiff_t; fixed.

For recent ISPs, software during CS_UNDERRUN handling must determine if the two residuals, firmware-calculated and FCP_RSP, are different to recognize if a frame has been dropped. Update the driver to catch this condition, and clear the SS_RESIDUAL_UNDER and lscsi_status bits. This logic is consistent with what earlier firmwares did by explicitly cracking open the FCP_RSP statuses and clearing SS_RESIDUAL_UNDER.

Recent ISPs need only the single MMIO BAR to manipulate HW registers.

By introducing the use_dac(), set_dac() and DMA_DAC_MASK macros, we can eliminate a lot of ifdefs from the code. We now rely on the compiler to optimise away a few things that we'd formerly relied on the preprocessor to do. This makes sym_setup_bus_dma_mask() small enough to inline into its only caller.

Instead of telling the reset routine that the command completed from sym_eh_done, do it from sym_xpt_done.
