[CPUFREQ] Make powernow-k7 work on SMP kernels. Even though powernow-k7 doesn't work in SMP environments, it can work on an SMP configured kernel if there's only one CPU present, however recalibrate_cpu_khz was returning -EINVAL on such kernels, so we failed to init the cpufreq driver.

This patch adds support for the new revision of the DViCO FusionHDTV DVB-T Lite, based on the zl10353 demod instead of mt352. Both mt352 and zl10353 revisions of this card have the same PCI subsystem ID. Signed-off-by:

This patch prevents the stradis driver from breaking all other saa7146 devices by removing the autodetection based on PCI subsystem ID 0000:0000 (no eeprom). Users that want to use the stradis driver will have to manually insert the module, or specify it in modprobe.conf Signed-off-by:

"return -err" and blindly inheriting the error code in the netlink failure exception handler causes errors codes to be returned as positive value therefore making them being ignored by the caller. May lead to sending out incomplete netlink messages. Signed-off-by:

The TCA_ACT_KIND attribute is used without checking its availability when dumping actions therefore leading to a value of 0x4 being dereferenced. The use of strcmp() in tc_lookup_action_n() isn't safe when fed with string from an attribute without enforcing proper NUL termination. Both bugs can be triggered with malformed netlink message and don't require any privileges. Signed-off-by:

As detailed at http://bugs.gentoo.org/131534 : 2.6.16 converted many ACPI debug messages into error or warning messages. One extraneous message was incorrectly converted, resulting in logs being flooded by "Handle is NULL and Pathname is relative" messages on some systems. This patch (part of a larger ACPICA commit) converts the message back to debug level. Signed-off-by:

Memory hotplug code of i386 adds memory to only highmem. So, if CONFIG_HIGHMEM is not set, CONFIG_MEMORY_HOTPLUG shouldn't be set. Otherwise, it causes compile error. In addition, many architecture can't use memory hotplug feature yet. So, I introduce CONFIG_ARCH_ENABLE_MEMORY_HOTPLUG. Signed-off-by:

This fixes some OOMs on 64bit systems with <4GB of RAM when accessing the cdrom. Do a safer check for when to enable DMA. Currently we enable ISA DMA for cases that do not need it, resulting in OOM conditions when ZONE_DMA runs out of space. Signed-off-by:

mthca does not restore the following PCI-X/PCI Express registers after reset: PCI-X device: PCI-X command register PCI-X bridge: upstream and downstream split transaction registers PCI Express : PCI Express device control and link control registers This causes instability and/or bad performance on systems where one of these registers is set to a non-default value by BIOS.

Fix nused counter. It's currently getting set to -1 rather than getting decremented by 1. Since nused never reaches 0, the "if (!free->hdr.nused)" check in xfs_dir2_leafn_remove() fails every time and xfs_dir2_shrink_inode() doesn't get called when it should. This causes extra blocks to be left on an empty directory and the directory in unable to be converted back to inline extent mode. Signed-off-by:

Fix nasty /proc vulnerability We have a bad interaction with both the kernel and user space being able to change some of the /proc file status. This fixes the most obvious part of it, but I expect we'll also make it harder for users to modify even their "own" files in /proc. Signed-off-by:

Based on a patch from Ernie Petrides During security research, Red Hat discovered a behavioral flaw in core dump handling. A local user could create a program that would cause a core file to be dumped into a directory they would not normally have permissions to write to. This could lead to a denial of service (disk consumption), or allow the local user to gain root privileges. Signed-off-by:

When a packet without any chunks is received, the newconntrack variable in sctp_packet contains an out of bounds value that is used to look up an pointer from the array of timeouts, which is then dereferenced, resulting in a crash.

I've been experimenting to track down the cause of suspend/resume problems on my Compaq Presario X1050 laptop: http://bugzilla.kernel.org/show_bug.cgi?id=6075 Essentially the ACPI Embedded Controller and keyboard controller would get into a bizarre, confused state after resume. I found that unloading the ohci1394 module before suspend and reloading it after resume made the problem go away. Diffing the dmesg output from resume, with and without the module loaded, I found that with the module loaded I was missing these: PM: Writing back config space on device 0000:02:00.0 at offset 1. (Was 2100080, writing 2100007) PM: Writing back config space on device 0000:02:00.0 at offset 3. (Was 0, writing 8008) PM: Writing back config space on device 0000:02:00.0 at offset 4. (Was 0, writing 90200000) PM: Writing back config space on device 0000:02:00.0 at offset 5. (Was 1, writing 2401) PM: Writing back config space on device 0000:02:00.0 at offset f. (Was 20000100, writing 2000010a) The default PCI driver performs the pci_restore_state when no driver is loaded for the device. When the ohci1394 driver is loaded, it is supposed to do this, however it appears not to do so. I created the patch below and tested it, and it appears to resolve the suspend problems I was having with the module loaded. I only added in the pci_save_state and pci_restore_state - however, though I know little of this hardware, surely the driver should really be doing more than this when suspending and resuming? Currently it does almost nothing, what if there are commands in progress, etc? Signed-off-by:
