2010-10-15llseek: automatically add .llseek fopArnd Bergmann
All file_operations should get a .llseek operation so we can make nonseekable_open the default for future file operations without a .llseek pointer. The three cases that we can automatically detect are no_llseek, seq_lseek and default_llseek. For cases where we can we can automatically prove that the file offset is always ignored, we use noop_llseek, which maintains the current behavior of not returning an error from a seek. New drivers should normally not use noop_llseek but instead use no_llseek and call nonseekable_open at open time. Existing drivers can be converted to do the same when the maintainer knows for certain that no user code relies on calling seek on the device file. The generated code is often incorrectly indented and right now contains comments that clarify for each added line why a specific variant was chosen. In the version that gets submitted upstream, the comments will be gone and I will manually fix the indentation, because there does not seem to be a way to do that using coccinelle. Some amount of new code is currently sitting in linux-next that should get the same modifications, which I will do at the end of the merge window. Many thanks to Julia Lawall for helping me learn to write a semantic patch that does all this. ===== begin semantic patch ===== // This adds an llseek= method to all file operations, // as a preparation for making no_llseek the default. // // The rules are // - use no_llseek explicitly if we do nonseekable_open // - use seq_lseek for sequential files // - use default_llseek if we know we access f_pos // - use noop_llseek if we know we don't access f_pos, // but we still want to allow users to call lseek // @ open1 exists @ identifier nested_open; @@ nested_open(...) { <+... nonseekable_open(...) ...+> } @ open exists@ identifier open_f; identifier i, f; identifier open1.nested_open; @@ int open_f(struct inode *i, struct file *f) { <+...

2010-10-13ioat2: fix performance regressionDan Williams
Commit 0793448 "DMAENGINE: generic channel status v2" changed the interface for how dma channel progress is retrieved. It inadvertently exported an internal helper function ioat_tx_status() instead of ioat_dma_tx_status(). The latter polls the hardware to get the latest completion state, while the helper just evaluates the current state without touching hardware. The effect is that we end up waiting for completion timeouts or descriptor allocation errors before the completion state is updated. iperf (before fix): [SUM] 0.0-41.3 sec 364 MBytes 73.9 Mbits/sec iperf (after fix): [SUM] 0.0- 4.5 sec 499 MBytes 940 Mbits/sec This is a regression starting with 2.6.35.

2010-09-23dmaengine: fix interrupt clearing for mv_xorSimon Guinot
When using simultaneously the two DMA channels on a same engine, some transfers are never completed. For example, an endless lock can occur while writing heavily on a RAID5 array (with async-tx offload support enabled). Note that this issue can also be reproduced by using the DMA test client. On a same engine, the interrupt cause register is shared between two DMA channels. This patch make sure that the cause bit is only cleared for the requested channel.

2010-08-04dma: dmatest: fix potential sign bugKulikov Vasiliy
'cnt' is unsigned, so this code may become wrong in future as dmatest_add_threads() can return error code: cnt = dmatest_add_threads(dtc, DMA_MEMCPY); thread_count += cnt > 0 ? cnt : 0; ^^^^^^^ Now it can return only -EINVAL if and only if second argument of dmatest_add_threads() is not one of DMA_MEMCPY, DMA_XOR, DMA_PQ. So, now it is not wrong but may become wrong in future.

2010-08-04ioat2: catch and recover from broken vtd configurations v6Dan Williams
On some platforms (MacPro3,1) the BIOS assigns the ioatdma device to the incorrect iommu causing faults when the driver initializes. Add a quirk to catch this misconfiguration and try falling back to untranslated operation (which works in the MacPro3,1 case). Assuming there are other platforms with misconfigured iommus teach the ioatdma driver to treat initialization failures as non-fatal (just fail the driver load and emit a warning instead of triggering a BUG_ON). This can be classified as a boot regression since 2.6.32 on affected platforms since the ioatdma module did not autoload prior to that kernel.

2010-05-23DMA: PL330: Add dma api driverJassi Brar
Add DMA Engine API driver for the PL330 DMAC. This driver is supposed to be reusable by various platforms that have one or more PL330 DMACs. Atm, DMA_SLAVE and DMA_MEMCPY capabilities have been implemented.
