2008-12-13kbuild: fix make incompatibilitySam Ravnborg
"Paul Smith" <psmith@gnu.org> reported that we would fail to build with a new check that may be enabled in an upcoming version of make. The error was: Makefile:442: *** mixed implicit and normal rules. Stop. The problem is that we did stuff like this: config %config: ... The solution was simple - the above was split into two with identical prerequisites and commands. With only three lines it was not worth to try to avoid the duplication.

2008-12-03genksyms: allow to ignore symbol checksum changesAndreas Gruenbacher
This adds an "override" keyword for use in *.symvers / *.symref files. When a symbol is overridden, the symbol's old definition will be used for computing checksums instead of the new one, preserving the previous checksum. (Genksyms will still warn about the change.) This is meant to allow distributions to hide minor actual as well as fake ABI changes. (For example, when extra type information becomes available because additional headers are included, this may change checksums even though none of the types used have actully changed.) This approach also allows to get rid of "#ifdef __GENKSYMS__" hacks in the code, which are currently used in some vendor kernels to work around checksum changes.

2008-12-03genksyms: track symbol checksum changesAndreas Gruenbacher
Sometimes it is preferable to avoid changes of exported symbol checksums (to avoid breaking externally provided modules). When a checksum change occurs, it can be hard to figure out what caused this change: underlying types may have changed, or additional type information may simply have become available at the point where a symbol is exported. Add a new --reference option to genksyms which allows it to report why checksums change, based on the type information dumps it creates with the --dump-types flag. Genksyms will read in such a dump from a previous run, and report which symbols have changed (and why). The behavior can be controlled for an entire build as follows: If KBUILD_SYMTYPES is set, genksyms uses --dump-types to produce *.symtypes dump files. If any *.symref files exist, those will be used as the reference to check against. If KBUILD_PRESERVE is set, checksum changes will fail the build.

2008-12-03tags and cscope support really belongs in a shell scriptSam Ravnborg
as they do not benefit from the make functionality. Moving the support to a shell script has several benefits: - The readability of the code has increased a lot - More people is able to extend the tags support - We see less changes to the top-level Makefile The shell script version includes improvements from: Alexey Dobriyan <adobriyan@gmail.com> (jump to kconfig symbols) Alexey Dobriyan <adobriyan@gmail.com> (drop ./ in paths) Ian Campbell <ijc@hellion.org.uk> (simplified find algorithms) This version has a few caveats: => It does not support ALLSOURCE_ARCHS - it is easy to add if it is really used => It assumes all archs have moved to arch/$ARCH/include - until that happens we have a few additional hits in the archs Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Cc: Alexey Dobriyan <adobriyan@gmail.com> Tested-by: Ian Campbell <ijc@hellion.org.uk>

2008-12-03kbuild: gen_init_cpio expands shell variables in file namesSally, Gene
Modify gen_init_cpio so that lines that specify files can contain what looks like a shell variable that's expanded during processing. For example: file /sbin/kinit ${RFS_BASE}/usr/src/klibc/kinit/kinit 0755 0 0 given RFS_BASE is "/some/directory" in the environment would be expanded to file /sbin/kinit /some/directory/usr/src/klibc/kinit/kinit 0755 0 0 If several environment variables appear in a line, they are all expanded with processing happening from left to right. Undefined variables expand to a null string. Syntax errors stop processing, letting the existing error handling show the user offending line. This patch helps embedded folks who frequently create several RFS directories and then switch between them as they're tuning an initramfs.

2008-12-03kbuild: expand -I in KBUILD_CPPFLAGSSam Ravnborg

2008-12-03kbuild: fix -I option expansion with O=... buildsSam Ravnborg
When adding extra -I options with O=... we could end up in a situation where there were no parameters to -I. So we had a commandline that looked like this: ... -I -Wall ... This had the undesired side effect that gcc assumed "-Wall" was a path to look for include files so this options was effectively ignored. This happens only when we build the generated module.mod.c files as part of the final modules builds and is as such harmless with current kbuild. This bug was exposed when we rearranged the options to gcc. Signed-off-by: Sam Ravnborg <sam@ravnborg.org>

2008-12-02vmscan: evict streaming IO firstRik van Riel
Count the insertion of new pages in the statistics used to drive the pageout scanning code. This should help the kernel quickly evict streaming file IO. We count on the fact that new file pages start on the inactive file LRU and new anonymous pages start on the active anon list. This means streaming file IO will increment the recent scanned file statistic, while leaving the recent rotated file statistic alone, driving pageout scanning to the file LRUs. Pageout activity does its own list manipulation.

2008-12-02bdi: register sysfs bdi device only once per queueKay Sievers
Devices which share the same queue, like floppies and mtd devices, get registered multiple times in the bdi interface, but bdi accounts only the last registered device of the devices sharing one queue. On remove, all earlier registered devices leak, stay around in sysfs, and cause "duplicate filename" errors if the devices are re-created. This prevents the creation of multiple bdi interfaces per queue, and the bdi device will carry the dev_t name of the block device which is the first one registered, of the pool of devices using the same queue.

2008-12-02amd74xx: workaround unreliable AltStatus register for nVidia controllersBartlomiej Zolnierkiewicz
It seems that on some nVidia controllers using AltStatus register can be unreliable so default to Status register if the PCI device is in Compatibility Mode. In order to achieve this: * Add ide_pci_is_in_compatibility_mode() inline helper to <linux/ide.h>. * Add IDE_HFLAG_BROKEN_ALTSTATUS host flag and set it in amd74xx host driver for nVidia controllers in Compatibility Mode. * Teach actual_try_to_identify() and drive_is_ready() about the new flag. This fixes the regression caused by removal of CONFIG_IDEPCI_SHARE_IRQ config option in 2.6.25 and using AltStatus register unconditionally when available (kernel.org bugs #11659 and #10216). [ Moreover for CONFIG_IDEPCI_SHARE_IRQ=y (which is what most people and distributions use) it never worked correctly. ] Thanks to Remy LABENE and Lars Winterfeld for help with debugging the problem.

2008-12-01i82875p_edac: fix module removeJarkko Lavinen
Fix module removal bugs of i82875p_edac. Also i82975x_edac code seems to have the same module removal bugs as in i82875p_edac. The problems were: 1. In module removal i82875p_remove_one() is never called. Variable i82875p_registered is newer changed from 1, which guarantees i82875p_remove_one() is not called (and even if it were called, it would be called in wrong order). As a result, the edac_mc workque is not stopped and keeps probing. If kernel debugging options are not enabled, user may not notice anything going wrong. if debugging options are enabled and I do "rmmod i82875p_edac", I get: edac debug: edac_pci_workq_function() checking BUG: unable to handle kernel paging request at f882d16f ... call trace: [<f8834df3>] ? edac_mc_workq_function+0x55/0x7e [edac_core] [<c0233974>] ? run_workqueue+0xd7/0x1a5 [<c023392f>] ? run_workqueue+0x92/0x1a5 [<f8834d9e>] ? edac_mc_workq_function+0x0/0x7e [edac_core] [<c0233af9>] ? worker_thread+0xb7/0xc3 [<c0236a7b>] ? autoremove_wake_function+0x0/0x33 [<c0233a42>] ? worker_thread+0x0/0xc3 [<c0236809>] ? kthread+0x3b/0x61 [<c02367ce>] ? kthread+0x0/0x61 [<c0204587>] ? kernel_thread_helper+0x7/0x10 Fix for this is to get rid of needles variable i82875p_registered altogether and run i82875p_remove_one() *before* pci_unregister_driver(). 2. edac_mc_del_mc() uses mci after freeing mci edac_mc_del_mc() calls calls edac_remove_sysfs_mci_device(). The kobject refcount of mci drops to 0 and mci is freed. After this mci is accessed via debug print and i82875p_remove_one() still uses mci->pvt and tries to free mci again with edac_mc_free(). The fix for this is add kobject_get(&mci->edac_mci_kobj) after edac_mc_alloc(). Then the mci is still available after returning from edac_mc_del_mc() with refcount 1, and mci->pvt is still available. When i82875p_remove_one() finally calls edac_mc_free(), this will cause kobject_put() and mci is released properly.

2008-12-01i82875p_edac: fix overflow device resource setupJarkko Lavinen
When I do "modprobe i82875p_edac" on my Asus P4C800 MB on kernels 2.6.26 or later, the module load fails due to BAR 0 collision. On 2.6.25 the module loads just fine. The overflow device on the MB seems to be hidden and its resources are not allocated at normal PCI bus init. Log shows the missing resource problem: EDAC DEBUG: i82875p_probe1() PCI: 0000:00:06.0 reg 10 32bit mmio: [fecf0000, fecf0fff] pci 0000:00:06.0: device not available because of BAR 0 [0xfecf0000-0xfecf0fff] collisions EDAC i82875p: i82875p_setup_overfl_dev(): Failed to enable overflow device The patch below fixes this by calling pci_bus_assign_resources() after the overflow device is revealed and added to the bus. With this patch I am again able to load and use the module.

2008-12-01fbdev: fix FB console blankingDmitry Baryshkov
The commit aef7db4bd5a3b6068dfa05919a3d685199eed116 fixed the problem with recursive locking in fb blanking code if blank is caused by user setting the /sys/class/graphics/fb*/blank. However this broke the fbcon timeout blanking. If you use a driver that defines ->fb_blank operation and at the same time that driver relies on other driver (e.g. backlight or lcd class) to blank the screen, when the fbcon times out and tries to blank the fb, it will call only fb driver blanker and won't notify the other driver. Thus FB output is disabled, but the screen isn't blanked. Restore fbcon blanking and at the same time apply the proper fix for the above problem: if fbcon_blank is called with FBINFO_FLAG_USEREVENT, we are already called through notification from fb_blank, thus we don't have to blank the fb again.
