2009-11-26block: add helpers to run flush_dcache_page() against a bio and a request's ↵Ilya Loginov
pages Mtdblock driver doesn't call flush_dcache_page for pages in request. So, this causes problems on architectures where the icache doesn't fill from the dcache or with dcache aliases. The patch fixes this. The ARCH_IMPLEMENTS_FLUSH_DCACHE_PAGE symbol was introduced to avoid pointless empty cache-thrashing loops on architectures for which flush_dcache_page() is a no-op. Every architecture was provided with this flush pages on architectires where ARCH_IMPLEMENTS_FLUSH_DCACHE_PAGE is equal 1 or do nothing otherwise. See "fix mtd_blkdevs problem with caches on some architectures" discussion on LKML for more information.

2009-11-23cciss: change Cmd_sg_list.sg_chain_dma type to dma_addr_tAlex Chiang
A recent commit broke the ia64 build: Author: Don Brace <brace@beardog.cce.hp.com> Date: Thu Nov 12 12:50:01 2009 -0600 cciss: Add enhanced scatter-gather support. because of this hunk: --- a/drivers/block/cciss.h +++ b/drivers/block/cciss.h +struct Cmd_sg_list { + SGDescriptor_struct *sgchain; + dma64_addr_t sg_chain_dma; + int chain_block_size; +}; The issue is that dma64_addr_t isn't #define'd on ia64. The way that we're using Cmd_sg_list.sg_chain_dma is to hold an address returned from pci_map_single(). + temp64.val = pci_map_single(h->pdev, + h->cmd_sg_list[c->cmdindex]->sgchain, + len, dir); + + h->cmd_sg_list[c->cmdindex]->sg_chain_dma = temp64.val; pci_map_single() returns a dma_addr_t too. This code will still work even on a 32-bit x86 build, where dma_addr_t is defined to be a u32 because it will simply be promoted to the __u64 that temp64.val is defined as. Thus, declaring Cmd_sg_list.sg_chain_dma as dma_addr_t is safe. Cc: Don Brace <brace@beardog.cce.hp.com> Cc: Stephen M.

2009-11-13cciss: Do not automatically rescan on UNIT ATTENTION/LUN DATA CHANGEDStephen M. Cameron
cciss: Do not automatically rescan on UNIT ATTENTION/LUN DATA CHANGED There are problems with doing this. If, say, several logical drives are deleted at once, several such UNIT ATTENTIONS will be encountered, often during the rescan triggered by the first such UNIT ATTENTION. The block layer may be in the midst of trying to add logical drives which were just deleted (resulting in the subsequent UNIT ATTENTION(s).) Making the rescan code robust enough to tolerate this kind of thing is too complicated for the moment. So, for now, we just don't do it. Note: This UNIT ATTENTION/LUN DATA CHANGED situation only occurs on the MSA2012. Signed-off-by: Stephen M. Cameron <scameron@beardog.cce.hp.com> Signed-off-by: Jens Axboe <jens.axboe@oracle.com>

2009-11-04block/ps3: fix slow VRAM IOHideyuki Sasaki
The current PS3 VRAM driver uses msleep() to wait for completion of RSX DMA transfers between system memory and VRAM. Depending on the system timing, the processing delay and overhead of this msleep() call can significantly impact VRAM driver IO. To avoid the condition, add a short duration (200 usec max) udelay() polling loop before entering the msleep() polling loop.

But the returned error code was wrong: to modprobe, the -EEXIST means that _this_ driver is already installed. It therefore doesn't produce the needed error message when _another_ driver is trying to register for the same device. Returning -EBUSY fixes the problem.
