How to use perf to log page faults
Hi, From the docs it seems that perf may be useful for logging page faults. I tried perf record -g -d -f -e page-faults <mycommand> but all I got were PERF_RECORD_MMAP events. I'm using 2.6.32. Ideally I'd like to collect fault addresses and userspace stacks that caused them. Isn't this what the page-fault e... 12 May 2010 18:06

[PATCH 4/4] msi-laptop: Add i8042 filter to sync sw state with BIOS when function key pressed
From: Lee, Chun-Yi <jlee(a)novell.com> There have some MSI netbook change devices state by EC when user press wlan/bluetooth/wwan function keys. So, add a i8042 filter to sync sw state with BIOS when function keys pressed. Signed-off-by: Lee, Chun-Yi <jlee(a)novell.com> Signed-off-by: Greg Kroah-Hartman <gregkh(a)su... 12 May 2010 15:51

[Patch 1/1] x86 pci: Add option to not assign BAR's if not already assigned
Subject: [Patch 1/1] x86 pci: Add option to not assign BAR's if not already assigned From: Mike Habeck <habeck(a)sgi.com> The Linux kernel assigns BARs that a BIOS did not assign, most likely to handle broken BIOSes that didn't enumerate the devices correctly. On UV the BIOS purposely doesn't assign I/O BARs for ce... 12 May 2010 14:43

[Patch 1/1] x86 efi: Fill all reserved memmap entries if add_efi_memmap specified.
Currently, the e820_reserve_resources() function does not add entries obtained via the "add_efi_memmap" kernel cmdline option. This causes /sys/firmware/memmap/... to be incomplete (stops after 128 entries). Utilities that examine these entries then do not get the complete picture of system memory.

[PATCH 3/5] track the root (oldest) anon_vma
Subject: track the root (oldest) anon_vma Track the root (oldest) anon_vma in each anon_vma tree. Because we only take the lock on the root anon_vma, we cannot use the lock on higher-up anon_vmas to lock anything. This makes it impossible to do an indirect lookup of the root anon_vma, since the data structures... 12 May 2010 14:43

[PATCH 0/5] always lock the root anon_vma
This patch series implements Linus's suggestion of always locking the root anon_vma. Because the lock in other anon_vmas no longer protects anything at all, we cannot do the "lock dance" that Mel's earlier patches implements and instead need a root pointer in the anon_vma. The only subtlety these patches rely on... 12 May 2010 14:43

[PATCH 1/5] rename anon_vma_lock to vma_lock_anon_vma
Subject: rename anon_vma_lock to vma_lock_anon_vma Rename anon_vma_lock to vma_lock_anon_vma. This matches the naming style used in page_lock_anon_vma and will come in really handy further down in this patch series.
