Enforce strict resource checking - disallowing access by native drivers to IO ports and memory regions claimed by ACPI firmware. The patch is mainly aimed to block native hwmon drivers from touching monitoring chips that ACPI thinks it own. If this causes a regression, boot with "acpi_enforce_resources=lax" which was the previous default. http://bugzilla.kernel.org/show_bug.cgi?id=12376 http://bugzilla.kernel.org/show_bug.cgi?id=12541 Signed-off-by: Luca Tettamanti <kronos.it@gmail.com> Acked-by: Pavel Machek <pavel@suse.cz> Acked-by: Jean Delvare <khali@linux-fr.org> Signed-off-by: Len Brown <len.brown@intel.com>

2009-03-24dynamic debug: combine dprintk and dynamic printkJason Baron
This patch combines Greg Bank's dprintk() work with the existing dynamic printk patchset, we are now calling it 'dynamic debug'. The new feature of this patchset is a richer /debugfs control file interface, (an example output from my system is at the bottom), which allows fined grained control over the the debug output. The output can be controlled by function, file, module, format string, and line number. for example, enabled all debug messages in module 'nf_conntrack': echo -n 'module nf_conntrack +p' > /mnt/debugfs/dynamic_debug/control to disable them: echo -n 'module nf_conntrack -p' > /mnt/debugfs/dynamic_debug/control A further explanation can be found in the documentation patch.

This patch extends command line option "i2c_bus=bus_id,clkrate" so that it allow to register additional I2C busses that are not registered with omap_register_i2c_bus from board initialization code. Purpose of this is to register additional board busses which are routed to external connectors only without any on board I2C devices.

This patch adds a new command line option "i2c_bus=bus_id,clkrate" into I2C bus registration helper. Purpose of the option is to override the default board specific bus speed which is supplied by the omap_register_i2c_bus. The default bus speed is typically set to speed of slowest I2C chip on the bus and overriding allow to use some experimental configurations or updated chip versions without any kernel modifications.

2009-03-20PCI: allow assignment of memory resources with a specified alignmentYuji Shimada
This patch allows memory resources to be assigned with a specified alignment at boot-time or run-time. The patch is useful when we use PCI pass-through, because page-aligned memory resources are required to securely share PCI resources with guest drivers. If you want to assign the resource at boot time, please set "pci=resource_alignment=" boot parameter. This is format of "pci=resource_alignment=" boot parameter: [<order of align>@][<domain>:]<bus>:<slot>.<func>[; ...] Specifies alignment and device to reassign aligned memory resources. If <order of align> is not specified, PAGE_SIZE is used as alignment. PCI-PCI bridge can be specified, if resource windows need to be expanded. This is example: pci=resource_alignment=20@07:00.0;18@0f:00.0;00:1d.7 If you want to assign the resource at run-time, please set "/sys/bus/pci/resource_alignment" file, and hot-remove the device and hot-add the device. For this purpose, fakephp or PCI hotplug interfaces can be used. The format of "/sys/bus/pci/resource_alignment" file is the same with boot parameter. You can use "," instead of ";". For example: # cd /sys/bus/pci # echo -n 20@12:00.0 > resource_alignment # echo 1 > devices/0000:12:00.0/remove # echo 1 > rescan Reviewed-by: Alex Chiang <achiang@hp.com> Reviewed-by: Yu Zhao <yu.zhao@intel.com> Signed-off-by: Yuji Shimada <shimada-yxb@necst.nec.co.jp> Signed-off-by: Jesse Barnes <jbarnes@virtuousgeek.org>

2009-03-02debug_objects: add boot-parameter toggle to turn object debugging off againKyle McMartin
While trying to debug why my Atom netbook is falling over booting rawhide debug-enabled kernels, I stumbled across the fact that we've been enabling object debugging by default. However, once you default it to on, you've got no way to turn it back off again at runtime. Add a boolean toggle to turn it off. I would just make it an int module_param, however people may already expect the boolean enable behaviour, so just add an analogue for disabling.
