The saved_state member of 'struct dev_pm_info' that's going to be removed is used in arch/arm/common/locomo.c, arch/arm/common/sa1111.c and arch/arm/mach-sa1100/neponset.c. Change the code in there to use local variables for saving the state of devices during suspend. Signed-off-by: NRafael J.

The checks if the device's parent is in the right state done in drivers/base/power/suspend.c and drivers/base/power/resume.c serve no particular purpose, since if the parent is in a wrong power state, the device's suspend or resume callbacks are supposed to return an error anyway. Moreover, they are also useless from the sanity checking point of view, because they rely on the code being checked to set dev->parent->power.power_state.event appropriately, which need not happen if that code is buggy. For these reasons they can be removed. Signed-off-by: NRafael J. Wysocki <rjw@sisk.pl> Acked-by: NDavid Brownell <dbrownell@users.sourceforge.net> Signed-off-by: NGreg Kroah-Hartman <gregkh@suse.de>

The suspend routines should be called for every device during a system sleep transition, regardless of the device's state, so that drivers can regard these method calls as notifications that the system is about to go to sleep, rather than as directives to put their devices into the 'off' state. This is documented in Documentation/power/devices.txt and is already done in the core resume code, so it seems reasonable to make the core suspend code behave accordingly. Signed-off-by: NRafael J.

The prev_state member of struct dev_pm_info (defined in include/linux/pm.h) is only used during a resume to check if the device's state before the suspend was 'off', in which case the device is not resumed. However, in such cases the decision whether or not to resume the device should be made on the driver level and the resume callbacks from the device's bus and class should be executed anyway (the may be needed for some things other than just powering on the device).

The patch below adds DMI/SMBIOS based module autoloading to the Linux kernel. The idea is to load laptop drivers automatically (and other drivers which cannot be autoloaded otherwise), based on the DMI system identification information of the BIOS. Right now most distros manually try to load all available laptop drivers on bootup in the hope that at least one of them loads successfully. This patch does away with all that, and uses udev to automatically load matching drivers on the right machines. Basically the patch just exports the DMI information that has been parsed by the kernel anyway to userspace via a sysfs device /sys/class/dmi/id and makes sure that proper modalias attributes are available. Besides adding the "modalias" attribute it also adds attributes for a few other DMI fields which might be useful for writing udev rules. This patch is not an attempt to export the entire DMI/SMBIOS data to userspace. We already have "dmidecode" which parses the complete DMI info from userspace. The purpose of this patch is machine model identification and good udev integration. To take advantage of DMI based module autoloading, a driver should export one or more MODULE_ALIAS fields similar to these: MODULE_ALIAS("dmi:*:svnMICRO-STARINT'LCO.,LTD:pnMS-1013:pvr0131*:cvnMICRO-STARINT'LCO.,LTD:ct10:*"); MODULE_ALIAS("dmi:*:svnMicro-StarInternational:pnMS-1058:pvr0581:rvnMSI:rnMS-1058:*:ct10:*"); MODULE_ALIAS("dmi:*:svnMicro-StarInternational:pnMS-1412:*:rvnMSI:rnMS-1412:*:cvnMICRO-STARINT'LCO.,LTD:ct10:*"); MODULE_ALIAS("dmi:*:svnNOTEBOOK:pnSAM2000:pvr0131*:cvnMICRO-STARINT'LCO.,LTD:ct10:*"); These lines are specific to my msi-laptop.c driver. They are basically just a concatenation of a few carefully selected DMI fields with all potentially bad characters stripped. Besides laptop drivers, modules like "hdaps", the i2c modules and the hwmon modules are good candidates for "dmi:" MODULE_ALIAS lines. Besides merely exporting the DMI data via sysfs the patch adds support for a few more DMI fields. Especially the CHASSIS fields are very useful to identify different laptop modules. The patch also adds working MODULE_ALIAS lines to my msi-laptop.c driver. I'd like to thank Kay Sievers for helping me to clean up this patch for posting it on lkml. Patch is against Linus' current GIT HEAD. Should probably apply to older kernels as well without modification.

Many places in kernel use seq_file API to iterate over a regular list_head. The code for such iteration is identical in all the places, so it's worth introducing a common helpers. This makes code about 300 lines smaller: The first version of this patch made the helper functions static inline in the seq_file.h header. This patch moves them to the fs/seq_file.c as Andrew proposed. The vmlinux .text section sizes are as follows: 2.6.22-rc1-mm1: 0x001794d5 with the previous version: 0x00179505 with this patch: 0x00179135 The config file used was make allnoconfig with the "y" inclusion of all the possible options to make the files modified by the patch compile plus drivers I have on the test node.

This is a hybrid version of the patch to add the LZO1X compression algorithm to the kernel. Nitin and myself have merged the best parts of the various patches to form this version which we're both happy with (and are jointly signing off). The performance of this version is equivalent to the original minilzo code it was based on. Bytecode comparisons have also been made on ARM, i386 and x86_64 with favourable results. There are several users of LZO lined up including jffs2, crypto and reiser4 since its much faster than zlib.

由 Jay Vosburgh 提交于
At present, when a device is enslaved to bonding, if ipv6 is active then addrconf will be initated on the slave (because it is closed then opened during the enslavement processing). This causes DAD and RS packets to be sent from the slave. These packets in turn can confuse switches that perform ipv6 snooping, causing them to incorrectly update their forwarding tables (if, e.g., the slave being added is an inactve backup that won't be used right away) and direct traffic away from the active slave to a backup slave (where the incoming packets will be dropped). This patch alters the behavior so that addrconf will only run on the master device itself. I believe this is logically correct, as it prevents slaves from having an IPv6 identity independent from the master. This is consistent with the IPv4 behavior for bonding. This is accomplished by (a) having bonding set IFF_SLAVE sooner in the enslavement processing than currently occurs (before open, not after), and (b) having ipv6 addrconf ignore UP and CHANGE events on slave devices. The eql driver also uses the IFF_SLAVE flag. I inspected eql, and I believe this change is reasonable for its usage of IFF_SLAVE, but I did not test it.
