Subject: [git pull] vfs and procfs fixes

	Fix for a couple of dumb leaks in path_lookupat() and a large pile of
procfs fixes.  Please, pull from
git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs-2.6.git/ for-linus

Shortlog:
Al Viro (7):
      fix leaks in path_lookupat()
      make sessionid permissions in /proc/*/task/* match those in /proc/*
      pagemap: close races with suid execve
      report errors in /proc/*/*map* sanely
      close race in /proc/*/environ
      auxv: require the target to be tracable (or yourself)
      deal with races in /proc/*/{syscall,stack,personality}

Stephen Wilson (12):
      x86: add context tag to mark mm when running a task in 32-bit compatibility mode
      x86: mark associated mm when running a task in 32 bit compatibility mode
      mm: arch: make get_gate_vma take an mm_struct instead of a task_struct
      mm: arch: make in_gate_area take an mm_struct instead of a task_struct
      mm: arch: rename in_gate_area_no_task to in_gate_area_no_mm
      mm: use mm_struct to resolve gate vma's in __get_user_pages
      mm: factor out main logic of access_process_vm
      mm: implement access_remote_vm
      proc: disable mem_write after exec
      proc: hold cred_guard_mutex in check_mem_permission()
      proc: make check_mem_permission() return an mm_struct on success
      proc: enable writing to /proc/pid/mem
