2007-07-12[MIPS] SMTC: Interrupt mask backstop hackKevin D. Kissell
To support multiple TC microthreads acting as "CPUs" within a VPE, VPE-wide interrupt mask bits must be specially manipulated during interrupt handling. To support legacy drivers and interrupt controller management code, SMTC has a "backstop" to track and if necessary restore the interrupt mask. This has some performance impact on interrupt service overhead. Disable it only if you know what you are doing. Signed-off-by: Ralf Baechle <ralf@linux-mips.org>

2007-07-12i2c: Fix the i2c_smbus_read_i2c_block_data() prototypeJean Delvare
Let the drivers specify how many bytes they want to read with i2c_smbus_read_i2c_block_data(). So far, the block count was hard-coded to I2C_SMBUS_BLOCK_MAX (32), which did not make much sense. Many driver authors complained about this before, and I believe it's about time to fix it. Right now, authors have to do technically stupid things, such as individual byte reads or full-fledged I2C messaging, to work around the problem. We do not want to encourage that. I even found that some bus drivers (e.g. i2c-amd8111) already implemented I2C block read the "right" way, that is, they didn't follow the old, broken standard. The fact that it was never noticed before just shows how little i2c_smbus_read_i2c_block_data() was used, which isn't that surprising given how broken its prototype was so far. There are some obvious compatiblity considerations: * This changes the i2c_smbus_read_i2c_block_data() prototype. Users outside the kernel tree will notice at compilation time, and will have to update their code. * User-space has access to i2c_smbus_xfer() directly using i2c-dev, so the changed expectations would affect tools such as i2cdump. In order to preserve binary compatibility, we give I2C_SMBUS_I2C_BLOCK_DATA a new numeric value, and define I2C_SMBUS_I2C_BLOCK_BROKEN with the old numeric value. When i2c-dev receives a transaction with the old value, it can convert it to the new format on the fly. Signed-off-by: Jean Delvare <khali@linux-fr.org>

2007-07-11[VLAN]: Fix MAC address handlingPatrick McHardy
The VLAN MAC address handling is broken in multiple ways. When the address differs when setting it, the real device is put in promiscous mode twice, but never taken out again. Additionally it doesn't resync when the real device's address is changed and needlessly puts it in promiscous mode when the vlan device is still down. Fix by moving address handling to vlan_dev_open/vlan_dev_stop and properly deal with address changes in the device notifier. Also switch to dev_unicast_add (which needs the exact same handling). Since the set_mac_address handler is identical to the generic ethernet one with these changes, kill it and use ether_setup(). Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S.

2007-07-11sysfs: add parameter "struct bin_attribute *" in .read/.write methods for ↵Zhang Rui
sysfs binary attributes Well, first of all, I don't want to change so many files either. What I do: Adding a new parameter "struct bin_attribute *" in the .read/.write methods for the sysfs binary attributes. In fact, only the four lines change in fs/sysfs/bin.c and include/linux/sysfs.h do the real work. But I have to update all the files that use binary attributes to make them compatible with the new .read and .write methods. I'm not sure if I missed any. :( Why I do this: For a sysfs attribute, we can get a pointer pointing to the struct attribute in the .show/.store method, while we can't do this for the binary attributes. I don't know why this is different, but this does make it not so handy to use the binary attributes as the regular ones. So I think this patch is reasonable. :) Who benefits from it: The patch that exposes ACPI tables in sysfs requires such an improvement. All the table binary attributes share the same .read method. Parameter "struct bin_attribute *" is used to get the table signature and instance number which are used to distinguish different ACPI table binary attributes. Without this parameter, we need to offer different .read methods for different ACPI table binary attributes. This is impossible as there are various ACPI tables on different platforms, and we don't know what they are until they are loaded.

2007-07-11sysfs: kill unnecessary attribute->ownerTejun Heo
sysfs is now completely out of driver/module lifetime game. After deletion, a sysfs node doesn't access anything outside sysfs proper, so there's no reason to hold onto the attribute owners. Note that often the wrong modules were accounted for as owners leading to accessing removed modules. This patch kills now unnecessary attribute->owner. Note that with this change, userland holding a sysfs node does not prevent the backing module from being unloaded. For more info regarding lifetime rule cleanup, please read the following message. http://article.gmane.org/gmane.linux.kernel/510293 (tweaked by Greg to not delete the field just yet, to make it easier to merge things properly.)

Add s_name to sysfs_dirent. This is to further reduce dependency to the associated dentry. Name is copied for directories and symlinks but not for attributes. Where possible, name dereferences are converted to use sd->s_name. sysfs_symlink->link_name and sysfs_get_name() are unused now and removed. This change allows symlink to be implemented using sysfs_dirent tree proper, which is the last remaining dentry-dependent sysfs walk.

2007-07-11ida: implement idr based id allocatorTejun Heo
Implement idr based id allocator. ida is used the same way idr is used but lacks id -> ptr translation and thus consumes much less memory. struct ida_bitmap is attached as leaf nodes to idr tree which is managed by the idr code. Each ida_bitmap is 128bytes long and contains slightly less than a thousand slots. ida is more aggressive with releasing extra resources acquired using ida_pre_get(). After every successful id allocation, ida frees one reserved idr_layer if possible. Reserved ida_bitmap is not freed automatically but only one ida_bitmap is reserved and it's almost always used right away. Under most circumstances, ida won't hold on to memory for too long which isn't actively used. Signed-off-by: Tejun Heo <htejun@gmail.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2007-07-11PM: Remove prev_state from struct dev_pm_infoRafael J. Wysocki
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 saved_state member of struct dev_pm_info, defined in include/linux/pm.h, is not used anywhere, so it can be removed. Signed-off-by: Rafael J. Wysocki <rjw@sisk.pl> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
