* [PATCH] w100fb: Update corgi platform code to match new driverRichard Purdie2005-09-071-3/+5
| | | | | | | | | | | | | This patch moves the platform specific Sharp SL-C7x0 LCD code from the w100fb driver into a more appropriate place and updates the Corgi code to match the new w100fb driver. It also updates the corgi touchscreen code to match the new simplified interface available from w100fb.

* [PATCH] w100fb: Rewrite for platform independenceRichard Purdie2005-09-071-5/+133
| | | | | | | | | | | | | | | | | | | | | The code w100fb was based on was horribly Sharp SL-C7x0 specific and there was little else that could be done as I had no access to anything else with a w100 in it. There is no real documentation about this chipset available. Ian Molton has access to other platforms with the w100 (Toshiba e-series) and so between us, we've improved w100fb and made it platform independent. Ian Molton also added support for the very similar w3220 and w3200 chipsets. There are a lot of changes here and it nearly amounts to a rewrite of the driver but it has been extensively tested and is being used in preference to the original driver in the Zaurus community. I'd therefore like to update the mainline code to reflect this.

* [PATCH] sd: initialize SD cardsPierre Ossman2005-09-073-0/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Support for the Secure Digital protocol in the MMC layer. A summary of the legal issues surrounding SD cards, as understood by yours truly: Members of the Secure Digital Association, hereafter SDA, are required to sign a NDA[1] before given access to any specifications. It has been speculated that including an SD implementation would forbid these members to redistribute Linux. This is the basic problem with SD support so it is unclear if it even is a problem since it has no effect on those of us that aren't members. The SDA doesn't seem to enforce these rules though since the patches included here are based on documentation made public by some of the members. The most complete specs[2] are actually released by Sandisk, one of the founding companies of the SDA. Because of this the NDA is considered a non-issue by most involved in the discussions concerning these patches. It might be that the SDA is only interested in protecting the so called "secure" bits of SD, which so far hasn't been found in any public spec. (The card is split into two sections, one "normal" and one "secure" which has an access scheme similar to TPM:s). (As a side note, Microsoft is working to make things easier for us since they want to be able to include the source code for a SD driver in one of their development kits. HP is making sure that the new NDA will allow a Linux implementation. So far only the SDIO specs have been opened up[3]. More will hopefully follow.)

If no MMC cards are found on a bus then the MMC layer proceeds looking for SD cards. Helper functions are extended to handle the special needs of SD cards.

| | | | | | | | | | | | | The IPMI power control function proc_write_chassctrl was badly written, it directly used userspace pointers, it assumed that strings were NULL terminated, and it used the evil sscanf function.

* [PATCH] ipmi: fix panic ipmb responseCorey Minyard2005-09-071-1/+2
| | | | | | | | | | | | | The "null message handler" in the IPMI driver is used in startup and panic situations to handle messages. It was only designed to work with messages from the local management controller, but in some cases it was used to get messages from remote managmenet controllers, and the system would then panic.

* [PATCH] struct dentry: place d_hash close to d_parent and d_name to speedup ↵Eric Dumazet2005-09-071-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | lookups dentry cache uses sophisticated RCU technology (and prefetching if available) but touches 2 cache lines per dentry during hlist lookup. This patch moves d_hash in the same cache line than d_parent and d_name fields so that : 1) One cache line is needed instead of two. 2) the hlist_for_each_rcu() prefetching has a chance to bring all the needed data in advance, not only the part that includes d_hash.next. I also changed one old comment that was wrong for 64bits. A further optimisation would be to separate dentry in two parts, one that is mostly read, and one writen (d_count/d_lock) to avoid false sharing on SMP/NUMA but this would need different field placement depending on 32bits or 64bits platform.

* [PATCH] cpusets: confine oom_killer to mem_exclusive cpusetPaul Jackson2005-09-071-0/+6
| | | | | | | | | | | | | | | | | | | | | Now the real motivation for this cpuset mem_exclusive patch series seems trivial. This patch keeps a task in or under one mem_exclusive cpuset from provoking an oom kill of a task under a non-overlapping mem_exclusive cpuset. Since only interrupt and GFP_ATOMIC allocations are allowed to escape mem_exclusive containment, there is little to gain from oom killing a task under a non-overlapping mem_exclusive cpuset, as almost all kernel and user memory allocation must come from disjoint memory nodes. This patch enables configuring a system so that a runaway job under one mem_exclusive cpuset cannot cause the killing of a job in another such cpuset that might be using very high compute and memory resources for a prolonged time.

* [PATCH] cpusets: formalize intermediate GFP_KERNEL containmentPaul Jackson2005-09-071-2/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch makes use of the previously underutilized cpuset flag 'mem_exclusive' to provide what amounts to another layer of memory placement resolution. With this patch, there are now the following four layers of memory placement available: 1) The whole system (interrupt and GFP_ATOMIC allocations can use this), 2) The nearest enclosing mem_exclusive cpuset (GFP_KERNEL allocations can use), 3) The current tasks cpuset (GFP_USER allocations constrained to here), and 4) Specific node placement, using mbind and set_mempolicy. These nest - each layer is a subset (same or within) of the previous. Layer (2) above is new, with this patch. The call used to check whether a zone (its node, actually) is in a cpuset (in its mems_allowed, actually) is extended to take a gfp_mask argument, and its logic is extended, in the case that __GFP_HARDWALL is not set in the flag bits, to look up the cpuset hierarchy for the nearest enclosing mem_exclusive cpuset, to determine if placement is allowed. The definition of GFP_USER, which used to be identical to GFP_KERNEL, is changed to also set the __GFP_HARDWALL bit, in the previous cpuset_gfp_hardwall_flag patch. GFP_ATOMIC and GFP_KERNEL allocations will stay within the current tasks cpuset, so long as any node therein is not too tight on memory, but will escape to the larger layer, if need be. The intended use is to allow something like a batch manager to handle several jobs, each job in its own cpuset, but using common kernel memory for caches and such. Swapper and oom_kill activity is also constrained to Layer (2). A task in or below one mem_exclusive cpuset should not cause swapping on nodes in another non-overlapping mem_exclusive cpuset, nor provoke oom_killing of a task in another such cpuset. Heavy use of kernel memory for i/o caching and such by one job should not impact the memory available to jobs in other non-overlapping mem_exclusive cpusets. This patch enables providing hardwall, inescapable cpusets for memory allocations of each job, while sharing kernel memory allocations between several jobs, in an enclosing mem_exclusive cpuset. Like Dinakar's patch earlier to enable administering sched domains using the cpu_exclusive flag, this patch also provides a useful meaning to a cpuset flag that had previously done nothing much useful other than restrict what cpuset configurations were allowed.

* [PATCH] cpusets: new __GFP_HARDWALL flagPaul Jackson2005-09-071-3/+5
| | | | | | | | | | | | | | | | | | | | | | Add another GFP flag: __GFP_HARDWALL. A subsequent "cpuset_zone_allowed" patch will use this flag to mark GFP_USER allocations, and distinguish them from GFP_KERNEL allocations. Allocations (such as GFP_USER) marked GFP_HARDWALL are constrainted to the current tasks cpuset. Other allocations (such as GFP_KERNEL) can steal from the possibly larger nearest mem_exclusive cpuset ancestor, if memory is tight on every node in the current cpuset. This patch collides with Mel Gorman's patch to reduce fragmentation in the standard buddy allocator, which adds two GFP flags. This was discussed on linux-mm in July. Most likely, one of his flags for user reclaimable memory can be the same as my __GFP_HARDWALL flag, under some generic name meaning its user address space memory.

* [PATCH] sunrpc: cache_register can use wrong module referenceBruce Allan2005-09-071-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | When registering an RPC cache, cache_register() always sets the owner as the sunrpc module. However, there are RPC caches owned by other modules. With the incorrect owner setting, the real owning module can be removed potentially with an open reference to the cache from userspace. For example, if one were to stop the nfs server and unmount the nfsd filesystem, the nfsd module could be removed eventhough rpc.idmapd had references to the idtoname and nametoid caches (i.e. /proc/net/rpc/nfs4.<cachename>/channel is still open). This resulted in a system panic on one of our machines when attempting to restart the nfs services after reloading the nfsd module. The following patch adds a 'struct module *owner' field in struct cache_detail. The owner is further assigned to the struct proc_dir_entry in cache_register() so that the module cannot be unloaded while user-space daemons have an open reference on the associated file under /proc.

* [PATCH] PNP: make pnp_dbg conditional directly on CONFIG_PNP_DEBUGBjorn Helgaas2005-09-071-1/+1
| | | | | | | | | | | Seems pointless to require .c files to test CONFIG_PNP_DEBUG and conditionally define DEBUG before including <linux/pnp.h>. Just test CONFIG_PNP_DEBUG directly in pnp.h.

* [PATCH] sonypi SPIC initialisation fixErik Waling2005-09-071-0/+2
| | | | | | | | | | | | Newer Sony VAIO models (VGN-S480, VGN-S460, VGN-S3XP etc) use a new method to initialize the SPIC device. The new way to initialize (and disable) the device comes directly from the AML code in the _CRS, _SRS and _DIS methods from the DSDT table. This patch adds support for the new models.

* [PATCH] disk quotas fail when /etc/mtab is symlinked to /proc/mountsMark Bellon2005-09-072-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If /etc/mtab is a regular file all of the mount options (of a file system) are written to /etc/mtab by the mount command. The quota tools look there for the quota strings for their operation. If, however, /etc/mtab is a symlink to /proc/mounts (a "good thing" in some environments) the tools don't write anything - they assume the kernel will take care of things. While the quota options are sent down to the kernel via the mount system call and the file system codes handle them properly unfortunately there is no code to echo the quota strings into /proc/mounts and the quota tools fail in the symlink case. The attached patchs modify the EXT[2|3] and JFS codes to add the necessary hooks. The show_options function of each file system in these patches currently deal with only those things that seemed related to quotas; especially in the EXT3 case more can be done (later?). Jan Kara also noted the difficulty in moving these changes above the FS codes responding similarly to myself to Andrew's comment about possible VFS migration. Issue summary: - FS codes have to process the entire string of options anyway. - Only FS codes that use quotas must have a show_options function (for quotas to work properly) however quotas are only used in a small number of FS. - Since most of the quota using FS support other options these FS codes should have the a show_options function to show those options - and the quota echoing becomes virtually negligible. Based on feedback I have modified my patches from the original: JFS a missing patch has been restored to the posting EXT[2|3] and JFS always use the show_options function - Each FS has at least one FS specific option displayed - QUOTA output is under a CONFIG_QUOTA ifdef - a follow-on patch will add a multitude of options for each FS EXT[2|3] and JFS "quota" is treated as "usrquota" EXT3 journalled data check for journalled quota removed EXT[2|3] mount when quota specified but not compiled in - no changes from my original patch. I tested the patch and the codes warn but - still mount. With all due respection I believe the comments otherwise were a - misread of the patch. Please reread/test and comment. XFS patch removed - the XFS team already made the necessary changes EXT3 mixing old and new quotas are handled differently (not purely exclusive) - if old and new quotas for the same type are used together the old type is silently depricated for compatability (e.g. usrquota and usrjquota) - mixing of old and new quotas is an error (e.g. usrjquota and grpquota) Signed-off-by: Mark Bellon <mbellon@mvista.com> Acked-by: Dave Kleikamp <shaggy@austin.ibm.com> Cc: Jan Kara <jack@ucw.cz> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
* [PATCH] auxiliary vector cleanupsH. J. Lu2005-09-0732-83/+196
| | | | | | | | | | | | The size of auxiliary vector is fixed at 42 in linux/sched.h. But it isn't very obvious when looking at linux/elf.h. This patch adds AT_VECTOR_SIZE so that we can change it if necessary when a new vector is added. Because of include file ordering problems, doing this necessitated the extraction of the AT_* symbols into a standalone header file.
