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.
