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
