* [PATCH] CHECK_IRQ_PER_CPU() to avoid dead code in __do_IRQ()Karsten Wiese2005-09-07
| | | | | | | | | | | | | | | | | | | IRQ_PER_CPU is not used by all architectures. This patch introduces the macros ARCH_HAS_IRQ_PER_CPU and CHECK_IRQ_PER_CPU() to avoid the generation of dead code in __do_IRQ(). ARCH_HAS_IRQ_PER_CPU is defined by architectures using IRQ_PER_CPU in their include/asm_ARCH/irq.h file. Through grepping the tree I found the following architectures currently use IRQ_PER_CPU: cris, ia64, ppc, ppc64 and parisc.

* [PATCH] Add rdinit parameter to pick early userspace initOlof Johansson2005-09-07
| | | | | | | | | | | | | | | | | | Since early userspace was added, there's no way to override which init to run from it. Some people tack on an extra cpio archive with a link from /init depending on what they want to run, but that's sometimes impractical. Changing the "init=" to also override the early userspace isn't feasible, since it is still used to indicate what init to run from disk when early userspace has completed doing whatever it's doing (i.e. load filesystem modules and drivers). Instead, introduce "rdinit=" and make it override the default "/init" if specified.

* [PATCH] proc: link count fixMiklos Szeredi2005-09-07
| | | | | | | | | | | | | | | | This patch fixes bug titled "sunrpc as module and bad proc/sys link count" reported by Jiri Slaby. The problem was, that only proc_dir_entry->nlink was updated and the corresponding inode->i_nlink was not. The fix is to implement the inode->getattr() method, and update i_nlink (if necessary). A quick audit of proc code shows that no other attribute changes after creation.

* [PATCH] Speedup FAT filesystem directory readsKarsten Wiese2005-09-07
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | OGAWA Hirofumi <hirofumi@mail.parknet.co.jp> This speeds up directory reads for large FAT partitions, if the buffercache has to be filled from the drive. Following values were taken from: $ time find path_to_freshly_mounted_fat > /dev/null on an otherwise idle system. FAT with 16KB Clusters on IDE attached drive: Factor 2 FAT with 32KB Clusters on USB2 attached drive: Factor 10 (!) Its less than 1/10 slower, if the buffercache is uptodate. The patch introduces the new function fat_dir_readahead(). fat_dir_readahead() calls sb_breadahead() to readahead a whole cluster, if the requested sector is the first one in a cluster. It is usefull to do this, because on FAT directories occupy whole clusters, with the exception of FAT12/FAT16 root dirs. Readahead is only done, if the cluster's first sector is not uptodate to avoid overhead, when the buffer cache is already uptodate. Note that under memory pressure, the maximal byte count wasted (read: has to be red from disk twice) is 1 cluster's size. Thats 64KB. fat_dir_readahead() is called from fat__get_entry(). There is also an unrelated cleanup at one spot: if (bh) brelse(bh); is replaced with: brelse(bh); brelse() can handle NULL pointer arguments by itself.

* [PATCH] flush icache early when loading moduleThomas Koeller2005-09-07
| | | | | | | | | | | | | | | Change the sequence of operations performed during module loading to flush the instruction cache before module parameters are processed. If a module has parameters of an unusual type that cannot be handled using the standard accessor functions param_set_xxx and param_get_xxx, it has to to provide a set of accessor functions for this type.

* [PATCH] sunrpc: cache_register can use wrong module referenceBruce Allan2005-09-07
| | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | Christoph Lameter <clameter@engr.sgi.com> When using a time interpolator that is susceptible to jitter there's potentially contention over a cmpxchg used to prevent time from going backwards. This is unnecessary when the caller holds the xtime write seqlock as all readers will be blocked from returning until the write is complete. We can therefore allow writers to insert a new value and exit rather than fight with CPUs who only hold a reader lock.

* [PATCH] disk quotas fail when /etc/mtab is symlinked to /proc/mountsMark Bellon2005-09-07
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>

Side note: ToPIC97 bridges (at least in Rev.5 i have) don't require this. Ryan Underwood <nemesis-lists@icequake.net> said: According to the mail that David Hinds received from a Toshiba engineer, ToPIC95 and 97 do require this, and ToPIC100 does not. Maybe you have a later revision. For all chips, 16-bit cards can be enabled through ExCA. So doesn't it make sense just to make this the default behavior for all Toshiba chips, to avoid corner cases showing up later? Daniel responded: I disagree with ryan to change anything for topic97 bridges. they work. and I couldn't find (read google) any report of a topic97 breaking on applying power with the CB registers. I'm having several toshba notebooks at work (and home) with topic95,97,100 bridges. Only the ones with a topic95 didn't work.

| | | | | | | | | | | | | | | | This patch contains the following cleanups: - make needlessly global functions static - journal.c: remove the unused global function __journal_internal_check and move the check to journal_init - remove the following write-only global variable: - journal.c: current_journal - remove the following unneeded EXPORT_SYMBOL: - journal.c: journal_recover Signed-off-by: Adrian Bunk <bunk@stusta.de> Acked-by: Andreas Dilger <adilger@clusterfs.com> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
* [PATCH] compat: be more consistent about [ug]id_tStephen Rothwell2005-09-07
| | | | | | | | | | | | | | | | | | | | When I first wrote the compat layer patches, I was somewhat cavalier about the definition of compat_uid_t and compat_gid_t (or maybe I just misunderstood :-)). This patch makes the compat types much more consistent with the types we are being compatible with and hopefully will fix a few bugs along the way. compat type type in compat arch __compat_[ug]id_t __kernel_[ug]id_t __compat_[ug]id32_t __kernel_[ug]id32_t compat_[ug]id_t [ug]id_t The difference is that compat_uid_t is always 32 bits (for the archs we care about) but __compat_uid_t may be 16 bits on some.

* [PATCH] use select in sound/isa/KconfigBodo Eggert2005-09-07
| | | | | | | | | | | | | In sound/isa/Kconfig, select ISAPNP and depend on ISAPNP are intermixed, resulting in funny behaviour. (Soundcarts get selectable if other soundcards are selected). This patch changes the "depend on ISAPNP"s to select.

* [PATCH] NMI: Update NMI users of RCU to use new APIPaul E. McKenney2005-09-07
| | | | | | | | | | | | | Uses of RCU for dynamically changeable NMI handlers need to use the new rcu_dereference() and rcu_assign_pointer() facilities. This change makes it clear that these uses are safe from a memory-barrier viewpoint, but the main purpose is to document exactly what operations are being protected by RCU. This has been tested on x86 and x86-64, which are the only architectures affected by this change.

* [PATCH] Provide better printk() support for SMP machinesDavid Howells2005-09-07
| | | | | | | | | | | | | | The attached patch prevents oopses interleaving with characters from other printks on other CPUs by only breaking the lock if the oops is happening on the machine holding the lock. It might be better if the oops generator got the lock and then called an inner vprintk routine that assumed the caller holds the lock, thus making oops reports "atomic".

* [PATCH] kallsyms: change compression algorithmPaulo Marques2005-09-07
| | | | | | | | | | | | | | | | | | | | | This patch changes the way the compression algorithm works. The base algorithm is similiar to the previous but we force the compressed token size to 2. Having a fixed size compressed token allows for a lot of optimizations, and that in turn allows this code to run over *all* the symbols faster than it did before over just a subset. Having it work over all the symbols will make it behave better when symbols change positions between passes, and the "inconsistent kallsyms" messages should become less frequent. In my tests the compression ratio was degraded by about 0.5%, but the results will depend greatly on the number of symbols to compress.
