2009-11-19Fix handling of the HP/Acer 'DMAR at zero' BIOS error for machines with ↵David Woodhouse
<4GiB RAM. Commit 86cf898e1d0fca245173980e3897580db38569a8 ("intel-iommu: Check for 'DMAR at zero' BIOS error earlier.") was supposed to work by pretending not to detect an IOMMU if it was actually being reported by the BIOS at physical address zero. However, the intel_iommu_init() function is called unconditionally, as are the corresponding functions for other IOMMU hardware. So the patch only worked if you have RAM above the 4GiB boundary. It caused swiotlb to be initialised when no IOMMU was detected during early boot, and thus the later IOMMU init would refuse to run. But if you have less RAM than that, swiotlb wouldn't get set up and the IOMMU _would_ still end up being initialised, even though we never claimed to detect it. This patch also sets the dmar_disabled flag when the error is detected during the initial detection phase -- so that the later call to intel_iommu_init() will return without doing anything, regardless of whether swiotlb is used or not.

2009-11-18strcmp: fix overflow and possibly signedness errorLinus Torvalds
Doing the strcmp return value as signed char __res = *cs - *ct; is wrong for two reasons. The subtraction can overflow because __res doesn't use a type big enough. Moreover the compared bytes should be interpreted as unsigned char as specified by POSIX. The same problem is fixed in strncmp.

2009-11-17[CPUFREQ] Fix stale cpufreq_cpu_governor pointerPrarit Bhargava
Dave, Attached is an update of my patch against the cpufreq fixes branch. Before applying the patch I compiled and booted the tree to see if the panic was still there -- to my surprise it was not. This is because of the conversion of cpufreq_cpu_governor to a char[]. While the panic is kaput, the problem of stale data continues and my patch is still valid. It is possible to end up with the wrong governor after hotplug events because CPUFREQ_DEFAULT_GOVERNOR is statically linked to a default, while the cpu siblings may have had a different governor assigned by a user. ie) the patch is still needed in order to keep the governors assigned properly when hotplugging devices Signed-off-by: Prarit Bhargava <prarit@redhat.com> Signed-off-by: Dave Jones <davej@redhat.com>

This is for consistency with various ioctl() operations that include the suffix "PGRP" in their names, and also for consistency with PRIO_PGRP, used with setpriority() and getpriority(). Also, using PGRP instead of GID avoids confusion with the common abbreviation of "group ID".

2009-11-17mm: allow memory hotplug and hibernation in the same kernelAndi Kleen
Allow memory hotplug and hibernation in the same kernel Memory hotplug and hibernation were exclusive in Kconfig. This is obviously a problem for distribution kernels who want to support both in the same image. After some discussions with Rafael and others the only problem is with parallel memory hotadd or removal while a hibernation operation is in process. It was also working for s390 before. This patch removes the Kconfig level exclusion, and simply makes the memory add / remove functions grab the pm_mutex to exclude against hibernation. Fixes a regression - old kernels didn't exclude memory hotadd and hibernation.

2009-11-17USB: option.c: add support for D-Link DWM-162-U5Zhang Le
Add D-Link DWM-162-U5 device id 1e0e:ce16 into option driver. The device has 4 interfaces, of which 1 is handled by storage and the other 3 by option driver. The device appears first as CD-only 05c6:2100 device and must be switched to 1e0e:ce16 mode either by using "eject CD" or usb_modeswitch. The MessageContent for usb_modeswitch.conf is: "55534243e0c26a85000000000000061b000000020000000000000000000000" Signed-off-by: Zhang Le <r0bertz@gentoo.org> Cc: stable <stable@kernel.org> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2009-11-17USB: usbmon: fix bug in mon_buff_area_shrinkAlan Stern
This patch (as1299b) fixes a bug in an error-handling path of usbmon's binary interface. The storage area for URB data is divided into fixed-size blocks. If an URB's data can't be copied, the area reserved for it should be decreased to the size of the truncated information (rounded up to a block boundary). Rounding up the amount to be removed and subtracting it from the reserved size is definitely the wrong thing to do. Also, when the data for an isochronous URB can't be copied, we can still copy the isoc packet descriptors. In fact the current code does copy the descriptors, but then sets the capture length to 0 so they remain inaccessible. The capture length should be reduced to the length of the descriptors, not set to 0.
