ima: remove ACPI dependency
On Tue, 4 May 2010, Mimi Zohar wrote: The ACPI dependency moved to the TPM, where it belongs. Although IMA per-se does not require access to the bios measurement log, verifying the IMA boot aggregate does, which requires ACPI.

remove all rcu head initializations, except on_stack initializations

We don't care about the RCU head state before passing it to call_rcu() anyway. Only leave the "on_stack" variants so debugobjects can keep track of objects on stack. T... 4 May 2010 20:11

Add a bootparameter to reserve high linear address space.

The idea was that you could boot a guest under VMWare fully virtualized then switch it to a VMI guest by loading a module. I don't think it eve... 4 May 2010 20:11

RFC: Network Plugin Architecture (NPA) for vmxnet3
Device passthrough technology allows a guest to bypass the hypervisor and drive the underlying physical device. VMware has been exploring various ways to deliver this technology to users in a manner which is easy to adopt. In this process we have prepared an architecture along with Intel - NPA (Network Plugin Archi... 10 May 2010 17:40

[GIT PULL] ocfs2 fixes for 2.6.34-rc
Linus et al, Here are all the fixes I currently have for 2.6.34-rc. A couple very notable. We could race truncate when O_DIRECT falls back to buffered I/O, and we could crash when creating a directory or symlink runs up against a user's quota. Please pull. Joel The following changes since commit 623e5a... 4 May 2010 19:05

[PATCH 01/13] tty: replace BKL with a new tty_lock
As a preparation for replacing the big kernel lock in the TTY layer, wrap all the callers in new macros tty_lock, tty_lock_nested and tty_unlock. Every user of tty_lock_nested should come with a comment explaining why we could get the lock recursively. This will help turning the BTM into a nonrecursive lock. ... 4 May 2010 19:05
