[PATCH RFC] efi: add and expose efi_partition_by_guid
EFI's GPT partitioning scheme expects that all partitions have a unique identifiers. After initial partition scanning, this information is completely lost to the rest of the kernel. efi_partition_by_guid exposes GPT parsing support in a limited fashion to allow other portions of the kernel to map a partition fro... 2 Aug 2010 15:52

Linux 2.6.33.7
I'm announcing the release of the 2.6.33.7 kernel. All users of the 2.6.33 kernel series should upgrade. This is the last 2.6.33 release, so everyone should be moved to the .34 kernel at this point in time, hopefully the .35 kernel instead of .34 as ..34 is not going to be maintained for much longer. The upd... 2 Aug 2010 15:51

[RFC] BTS based perf user callchains
Hi, As you may know there is an issue with user stacktraces: it requires userspace apps to be built with frame pointers. So there is something we can try: dump a piece of the top user stack page each time we have an event hit and let the tools deal with that later using the dwarf informations.
