Text Edit Lock and Immediate Values for 2.6.25-rc8-mm1

Hi Andrew,

Here is the complete patchset required to get basic Immediate Values support ported to 2.6.25-rc8-mm1. It provides the "simple", non nmi-safe version of immediate values, which means that immediate values should not be used in code paths reachable by NMI or MCE handlers. This version also uses stop_machine_run() for immediate values updates, which is a very heavy lock. In order to make incremental, easy to review, changes, I think we could start by this "simple" version as a first step before we switch to the nmi-safe version later.

It applies at the end of your series files in the following order :

# The following patches are required for any kind of immediate values

# implementation
kprobes-use-mutex-for-insn-pages.patch
kprobes-dont-use-kprobes-mutex-in-arch-code.patch
