Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jmorris/security-testing-2.6

* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jmorris/security-testing-2.6: (26 commits)
  selinux: include vmalloc.h for vmalloc_user
  secmark: fix config problem when CONFIG_NF_CONNTRACK_SECMARK is not set
  selinux: implement mmap on /selinux/policy
  SELinux: allow userspace to read policy back out of the kernel
  SELinux: drop useless (and incorrect) AVTAB_MAX_SIZE
  SELinux: deterministic ordering of range transition rules
  kernel: roundup should only reference arguments once
  kernel: rounddown helper function
  secmark: export secctx, drop secmark in procfs
  conntrack: export lsm context rather than internal secid via netlink
  security: secid_to_secctx returns len when data is NULL
  secmark: make secmark object handling generic
  secmark: do not return early if there was no error
  AppArmor: Ensure the size of the copy is < the buffer allocated to hold it
  TOMOYO: Print URL information before panic().
  security: remove unused parameter from security_task_setscheduler()
  tpm: change 'tpm_suspend_pcr' to be module parameter
  selinux: fix up style problem on /selinux/status
  selinux: change to new flag variable
  selinux: really fix dependency causing parallel compile failure.
