Cover letter [patch 00/11] Text Edit Lock / text poke

Hi Andrew,

This new version includes a rewrite of the i386 and x86_64 text edit lock using text poke. I clear and set the WP cr0 bit instead of changing the page attributes when patching RO code.

It applies to 2.6.23-rc2-mm2 in this order:

kprobes-use-mutex-for-insn-pages.patch kprobes-dont-use-kprobes-mutex-in-arch-code.patch kprobes-declare-kprobes-mutex-static.patch text-edit-lock-architecture-independent-code.patch text-edit-lock-alternative-i386-and-x86_64.patch text-edit-lock-kprobes-architecture-independent.patch text-edit-lock-kprobes-i386.patch text-edit-lock-kprobes-x86_64.patch text-edit-lock-i386-standardize-debug-rodata.patch text-edit-lock-x86_64-standardize-debug-rodata.patch
