[PATCH 1/3] mem-hotplug: separate setup_per_cpu_pageset() into separate functions
From: Wu Fengguang <fengguang.wu(a)intel.com> No behavior change here. Move some of setup_per_cpu_pageset() code into a new function setup_zone_pageset() that will be useful for memory hotplug.

[PATCH 0/3] Fix boot_pageset sharing issue for new populated zones of hotadded nodes
In our recent cpu/memory hotadd testing, with multiple nodes hotadded, kernel easily panics under stress workload like kernel building. The root cause is that the new populated zones of hotadded nodes are sharing same per_cpu_pageset, i.e. boot strapping boot_pageset, which finally causes page state wrong. The... 17 May 2010 04:47

[RFC 1/2] Add HW_ERR printk prefix for hardware error logging
This makes hardware error related log in printk log more explicit. So that the users can report it to hardware vendor instead of LKML or software vendor.

[PATCH] x86, MCE, fix MSR_IA32_MCI_CTL2 CMCI threshold setup
It is reported that CMCI is not raised when number of corrected error reaches preset threshold. After inspection, it is found that MSR_IA32_MCI_CTL2 threshold field is not setup properly. This patch fixed it. Changelog: v2: - Rename CMCI_EN to MCI_CTL2_CMCI_EN and CMCI_THRESHOLD_MASK to MCI_CTL2_CMCI_T... 17 May 2010 04:47

[PATCH 1/4] v4l: Introduce video_ioctl2_bkl
video_ioctl2 is a generic ioctl helper used by a lot of drivers. Most of them put it as their bkl'ed .ioctl callback, then provide a bkl'ed version of this helper so that drivers can use it as an unlocked_ioctl callback, making it easy to remove the .ioctl field from the v4l fops.

Which function returns LWP in Linux.
Hi, For a process, we have different PIDs. For threads under a single processes, we have different LWP id, but same PID in Linux. ex. root(a)pc:/home/srinivas# ps -eLf UID PID PPID LWP C STIME TIME CMD root 100 1 100 0 May13 00:00:02 ./a.out root 100 1 ... 17 May 2010 14:39
