df_03_sysfs_release_fix.patch Some attributes are allocated dynamically (e.g. module and device parameters) and are usually deallocated when the assoicated kobject is released. So, it's not safe to access attr after putting the kobject. Signed-off-by: Tejun Heo <tj@home-tj.org> Signed-off-by: Greg Kroah-Hartman <greg@kroah.com>

df_02_bus_rescan_devcies_fix.patch bus_rescan_devices() eventually calls device_attach() and thus requires write locking the corresponding bus. The original code just called bus_for_each_dev() which only read locks the bus. This patch separates __bus_for_each_dev() and __bus_for_each_drv(), which don't do locking themselves, out from the original functions and call them with read lock in the original functions and with write lock in bus_rescan_devices().

Add the sysfs path of the physical device to the hotplug event of class and block devices. This should solve the userspace issue not to know if the device is a virtual one and the "device" symlink will never be created, but we sit there and wait for it to show up not knowing when we should give up. Also the bus name is added to the hotplug event, so we don't need to reverse lookup in the /sys/bus/* directory which bus our physical device belongs to. This is e.g. the value matched against the BUS= key, that may be used in an udev rule. This is a PCI network card: ACTION=add SUBSYSTEM=net DEVPATH=/class/net/eth0 PHYSDEVPATH=/devices/pci0000:00/0000:00:1e.0/0000:02:01.0 PHYSDEVBUS=pci INTERFACE=eth0 SEQNUM=827 PATH=/sbin:/bin:/usr/sbin:/usr/bin HOME=/ This is a IDE CDROM: ACTION=add SUBSYSTEM=block DEVPATH=/block/hdc PHYSDEVPATH=/devices/pci0000:00/0000:00:1f.1/ide1/1.0 PHYSDEVBUS=ide SEQNUM=1017 PATH=/sbin:/bin:/usr/sbin:/usr/bin HOME=/ This is an USB-stick partition: ACTION=add SUBSYSTEM=block DEVPATH=/block/sda/sda1 PHYSDEVPATH=/devices/pci0000:00/0000:00:1d.1/usb3/3-1/3-1:1.0/host1/target1:0:0/1:0:0:0 PHYSDEVBUS=scsi SEQNUM=1032 PATH=/sbin:/bin:/usr/sbin:/usr/bin HOME=/ Signed-off-by: Kay Sievers <kay.sievers@vrfy.org> Signed-off-by: Greg Kroah-Hartman <greg@kroah.com>

The patch below does the following cleanups for the sysfs code: - remove the unused global function sysfs_mknod - make some structs and functions static Please check whether this patch is correct, or whether some of the things I made static should be used globally in the forseeable future.

The new atyfb has the return value for the Power Management routine wrong. This prevents sleep from working on PowerBooks with mach64 video chips. This fixes it. Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

XFree (and X.org) has both always been broken in their conversion of the DPMS blanking mode when passing to the kernel ioctl FBIOBLANK (in fbdev mode). This patch makes sure that at least the value passed by userland stays in the legal range, which has the side effect that an X DPMS POWERDOWN request will result as an fbdev VESA_POWERDOWN request at the fbdev level now, instead of an out-of-range value.

The default interruption handler "handle_interruption" does not properly check to see if the faulting space is the same as the users space. The problem lies in the fact that if a fault happens on the gateway we will not deliver signals to the process, the process will not die, and we may continue handling the same fault in a loop forever. Any malicious user code can crash the kernel by jumping into the gateway page at an inopportune address. The solution is to check if the user has the right privilege and if the spaces match, both faulting and currently active. The best action is to force the process back to it's own space of execution at address zero, and let it take a SIGSEGV. The process can never recover from this because it happens immediately after the return from the interrupt via rfi or rfir. Committed-by: Carlos O'Donell <carlos@parisc-linux.org>

- Fix Astro/Elroy LMMIO space reporting in /proc/iomem. - Output in /proc/iomem include PCI bus number and "Extra LMMIO" range. - LBA now reports proper addresses routed down from SBA. - add mercury_cfg_ops. This fixes the tg3 init delay problem. PDC took ~20ms per PCI cfg write. tg3 performs ~1600 writes (~30 seconds per NIC) during init. Alternative is the relocate PDC to host ram. But that would burn ~4MB of RAM. This is cheaper. - add PCI_F_EXTEND to asm/pci.h - replaces private definitions Committed-by: Grant Grundler <grundler@parisc-linux.org>

Patch from George G. Davis The Lubbock PCMCIA socket driver, drivers/pcmcia/pxa2xx_lubbock.c, lacks a MODULE_LICENSE declaration. This patch merely adds the missing MODULE_LICENSE declaration to eliminate tainted kernel warnings when this driver is built as a module. I have intentionally not used the Dual MPL/GPL license in this case because 1) current linux-2.6.10-rc1 PXA PCMCIA drivers use only the GPL license, 2) the original source files on which the PXA PCMCIA drivers are based, i.e. the SA11xx PCMCIA drivers, state: "If you wish to allow the use of your version of this file only under the terms of the GPL and not to allow others to use your version of this file under the MPL, indicate your decision by deleting the provisions above and replace them with the notice and other provisions required by the GPL."

Here's the patch that supercedes the one I asked you to drop. It changes the fan speed logic so that the fans will go incrementally fast instead of using just two steps. Also, it starts and stops both fans instead of just one on Powerbooks 15" and 17" (functionality asked by most of the Albooks users on Debian's ML, and justified by the fact that fan 1 and fan 2 do not correspond to CPU and GPU, as we previously thought).
