Enabling PXA DMA for the smc91x on the logicpd pxa270 produces unacceptable interference with the TFT panel, so disable it. Also delete the lpd270 versions of the SMC_{in,out}[bl]() macros, as they aren't used, since the board only supports 16bit accesses.

On the 88E805X chipsets (used in laptops), the PHY was not getting powered out of shutdown properly. The variable reg1 was getting reused incorrectly. This is probably the cause of the bug. http://bugzilla.kernel.org/show_bug.cgi?id=6471Signed-off-by:

While busy-waiting for completion, check the hardware after scheduling; don't schedule and then immediately check the _timeout_. If the yield() took a long time (as it does on my OLPC prototype board when it's busy), we'd report a timeout even though the hardware was now ready. This fixes it, and also switches the yield() for a cond_resched() because we don't actually want to be _that_ nice about it. I see nice tightly-packed SMBus transactions now, rather than waiting for milliseconds between successive phases. Actually, we shouldn't be busy-waiting here at all. We should be using interrupts. That's an exercise for another day though. Signed-off-by:

I saw an oops down this path when trying to create a new file on a UDF filesystem which was internally marked as readonly, but mounted rw: udf_create udf_new_inode new_inode alloc_inode udf_alloc_inode udf_new_block returns EIO due to readonlyness iput (on error) udf_put_inode udf_discard_prealloc udf_next_aext udf_current_aext udf_get_fileshortad OOPS the udf_discard_prealloc() path was examining uninitialized fields of the udf inode. udf_discard_prealloc() already has this code to short-circuit the discard path if no extents are preallocated: if (UDF_I_ALLOCTYPE(inode) == ICBTAG_FLAG_AD_IN_ICB || inode->i_size == UDF_I_LENEXTENTS(inode)) { return; } so if we initialize UDF_I_LENEXTENTS(inode) = 0 earlier in udf_new_inode, we won't try to free the (not) preallocated blocks, since this will match the i_size = 0 set when the inode was initialized.

A patch in -mm kernel correct the parsing of "address resources" of pnpacpi. Before we assumed it was memory only, but it could be also IO. But this change show an hidden bug : some resources could be producer type that are not handled by pnp layer. So we should ignore the producer resources. This patch fixes bug 6292 (http://bugzilla.kernel.org/show_bug.cgi?id=6292). Some devices like PNP0A03 have 0xd00-0xffff and 0x0-0xcf7 as IO producer resources. Before correcting "address resources" parsing, it was seen as memory and was harmless, because nobody tried to reserve this memory range as it should be IO. With the correction it become IO resources, and make failed all others device that want to register IO in this range and use pnp layer (like a ISA sound card). The solution is to ignore producer resources Signed-off-by:

reiserfs_write_full_page does zero bytes in the file past eof, but it may call get_block on those buffers as well. On machines where the page size is larger than the blocksize, this can result in mmaped files incorrectly growing up to a block boundary during writepage. The fix is to avoid calling get_block for any blocks that are entirely past eof Signed-off-by:

This patch is for collision check enhancement for memory hot add. It's better to do resouce collision check before doing memory hot add, which will touch memory management structures. And add_section() should check section exists or not before calling sparse_add_one_section(). (sparse_add_one_section() will do another check anyway. but checking in memory_hotplug.c will be easy to understand.) Signed-off-by:

add_memory() does all necessary check to avoid collision. then, acpi layer doesn't have to check region by itself. (*) pfn_valid() just returns page struct is valid or not. It returns 0 if a section has been already added even is ioresource is not added. ioresource collision check in mm/memory_hotplug.c can do more precise collistion check. added enabled bit check just for sanity check..

This patch changes the returned value to fit in requested area. Signed-off-by:

In bugzilla #6941, Jens Kilian reported: "The function befs_utf2nls (in fs/befs/linuxvfs.c) writes a 0 byte past the end of a block of memory allocated via kmalloc(), leading to memory corruption. This happens only for filenames which are pure ASCII and a multiple of 4 bytes in length. [...] Without DEBUG_SLAB, this leads to further corruption and hard lockups; I believe this is the bug which has made kernels later than 2.6.8 unusable for me. (This must be due to changes in memory management, the bug has been in the BeFS driver since the time it was introduced (AFAICT).) Steps to reproduce: Create a directory (in BeOS, naturally :-) with files named, e.g., "1", "22", "333", "4444", ... Mount it in Linux and do an "ls" or "find"" This patch implements the suggested fix. Credits to Jens Kilian for debugging the problem and finding the right fix. Signed-off-by:

The hvsi driver is used only on IBM pSeries PowerPC boxes. The driver was originally written by Hollis Blanchard, who has delegated maintainership to me.

If we don't find the item we are lookng for, we allocate a new one, and then grab the lock again and search to see if it has been added while we did the alloc. If it had been added we need to 'cache_put' the newly created item that we are never going to use. But as it hasn't been initialised properly, putting it can cause an oops. So move the ->init call earlier to that it will always be fully initilised if we have to put it. Thanks to Philipp Matthias Hahn <pmhahn@svs.Informatik.Uni-Oldenburg.de> for reporting the problem.

The POSIX_FADV_NOREUSE hint means "the application will use this range of the file a single time". It seems to be intended that the implementation will use this hint to perform drop-behind of that part of the file when the application gets around to reading or writing it. However for reasons which aren't obvious (or sane?) I mapped POSIX_FADV_NOREUSE onto POSIX_FADV_WILLNEED. ie: it does readahead. That's daft. So for now, make POSIX_FADV_NOREUSE a no-op. This is a non-back-compatible change. If someone was using POSIX_FADV_NOREUSE to perform readahead, they lose. The likelihood is low. If/when we later implement POSIX_FADV_NOREUSE things will get interesting - to do it fully we'll need to maintain file offset/length ranges and peform all sorts of complex tricks, and managing the lifetime of those ranges' data structures will be interesting.. A sensible implementation would probably ignore the file range and would simply mark the entire file as needing some form of drop-behind treatment.
