2006-01-06[PATCH] reiser4: vfs: add truncate_inode_pages_range()Hans Reiser2-7/+39
This patch makes truncate_inode_pages_range from truncate_inode_pages. truncate_inode_pages became a one-liner call to truncate_inode_pages_range. Reiser4 needs truncate_inode_pages_ranges because it tries to keep correspondence between existences of metadata pointing to data pages and pages to which those metadata point to. So, when metadata of certain part of file is removed from filesystem tree, only pages of corresponding range are to be truncated.

2006-01-06[PATCH] mm: fix __alloc_pages cpuset ALLOC_* flagsPaul Jackson1-3/+2
Two changes to the setting of the ALLOC_CPUSET flag in mm/page_alloc.c:__alloc_pages() - A bug fix - the "ignoring mins" case should not be honoring ALLOC_CPUSET. This case of all cases, since it is handling a request that will free up more memory than is asked for (exiting tasks, e.g.) should be allowed to escape cpuset constraints when memory is tight. - A logic change to make it simpler. Honor cpusets even on GFP_ATOMIC (!wait) requests. With this, cpuset confinement applies to all requests except ALLOC_NO_WATERMARKS, so that in a subsequent cleanup patch, I can remove the ALLOC_CPUSET flag entirely. Since I don't know any real reason this logic has to be either way, I am choosing the path of the simplest code.

2006-01-06[PATCH] knfsd: fix hash function for IP addresses on 64bit little-endian ↵NeilBrown1-1/+13
machines. The hash.h hash_long function, when used on a 64 bit machine, ignores many of the middle-order bits. (The prime chosen it too bit-sparse). IP addresses for clients of an NFS server are very likely to differ only in the low-order bits. As addresses are stored in network-byte-order, these bits become middle-order bits in a little-endian 64bit 'long', and so do not contribute to the hash. Thus you can have the situation where all clients appear on one hash chain. So, until hash_long is fixed (or maybe forever), us a hash function that works well on IP addresses - xor the bytes together. Thanks to "Iozone" <capps@iozone.org> for identifying this problem.

2006-01-06[PATCH] nbd: fix TX/RX race conditionHerbert Xu2-62/+68
Janos Haar of First NetCenter Bt. reported numerous crashes involving the NBD driver. With his help, this was tracked down to bogus bio vectors which in turn was the result of a race condition between the receive/transmit routines in the NBD driver. The bug manifests itself like this: CPU0 CPU1 do_nbd_request add req to queuelist nbd_send_request send req head for each bio kmap send nbd_read_stat nbd_find_request nbd_end_request kunmap When CPU1 finishes nbd_end_request, the request and all its associated bio's are freed. So when CPU0 calls kunmap whose argument is derived from the last bio, it may crash. Under normal circumstances, the race occurs only on the last bio. However, if an error is encountered on the remote NBD server (such as an incorrect magic number in the request), or if there were a bug in the server, it is possible for the nbd_end_request to occur any time after the request's addition to the queuelist. The following patch fixes this problem by making sure that requests are not added to the queuelist until after they have been completed transmission. In order for the receiving side to be ready for responses involving requests still being transmitted, the patch introduces the concept of the active request. When a response matches the current active request, its processing is delayed until after the tranmission has come to a stop. This has been tested by Janos and it has been successful in curing this race condition. From: Herbert Xu <herbert@gondor.apana.org.au> Here is an updated patch which removes the active_req wait in nbd_clear_queue and the associated memory barrier. I've also clarified this in the comment.

2006-01-06[PATCH] pcmcia: properly handle static mem, but dynamic io socketsDominik Brodowski3-2/+107
Some PCMCIA sockets have statically mapped memory windows, but dynamically mapped IO windows. Using the "nonstatic" socket library is inpractical for them, as they do neither need a resource database (as we can trust the kernel resource database on m68k and ppc) nor lots of other features of that library.

2006-01-06[PATCH] pcmcia: unify attach, EVENT_CARD_INSERTION handlers into one probe ↵Dominik Brodowski48-2233/+472
callback Unify the EVENT_CARD_INSERTION and "attach" callbacks to one unified probe() callback. As all in-kernel drivers are changed to this new callback, there will be no temporary backwards-compatibility. Inside a probe() function, each driver _must_ set struct pcmcia_device *p_dev->instance and instance->handle correctly. With these patches, the basic driver interface for 16-bit PCMCIA drivers now has the classic four callbacks known also from other buses: int (*probe) (struct pcmcia_device *dev); void (*remove) (struct pcmcia_device *dev); int (*suspend) (struct pcmcia_device *dev); int (*resume) (struct pcmcia_device *dev); Signed-off-by: Dominik Brodowski <linux@dominikbrodowski.net>

2006-01-05[ATYFB]: Fix onboard video on SPARC Blade 100 for 2.6.{13,14,15}Luis F. Ortiz1-1/+1
I have recently been switching from using 2.4.32 on my trusty old Sparc Blade 100 to using 2.6.15 . Some of the problems I ran into were distorted video when the console was active (missing first character, skipped dots) and when running X windows (colored snow, stripes, missing pixels). A quick examination of the 2.6 versus 2.4 source for the ATY driver revealed alot of changes. A closer look at the code/data for the 64GR/XL chip revealed two minor "typos" that the rewriter(s) of the code made. The first is a incorrect clock value (230 .vs. 235) and the second is a missing flag (M64F_SDRAM_MAGIC_PLL). Making both these changes seems to have fixed my problem. I tend to think the 235 value is the correct one, as there is a 29.4 Mhz clock crystal close to the video chip and 235.2 (29.4*8) is too close to 235 to make it a coincidence. The flag for M64F_SDRAM_MAGIC_PLL was dropped during the changes made by adaplas in file revision 1.72 on the old bitkeeper repository. The change relating to the clock rate has been there forever, at least in the 2.6 tree. I'm not sure where to look for the old 2.5 tree or if anyone cares when it happened. On SPARC Blades 100's, which use the ATY MACH64GR video chipset, the clock crystal frequency is 235.2 Mhz, not 230 Mhz. The chipset also requires the use of M64F_SDRAM_MAGIC_PLL in order to setup the PLL properly for the DRAM. Signed-off-by: Luis F. Ortiz <lfo@Polyad.Org> Signed-off-by: David S.
