Merge branch 'next' of git://git.kernel.org/pub/scm/linux/kernel/git/jmorris/security-testing-2.6
* 'next' of git://git.kernel.org/pub/scm/linux/kernel/git/jmorris/security-testing-2.6: (30 commits) TOMOYO: Add recursive directory matching operator support. remove CONFIG_SECURITY_FILE_CAPABILITIES compile option SELinux: print denials for buggy kernel with unknown perms Silence the existing API for capability version compatibility check. LSM: Move security_path_chmod()/security_path_chown() to after mutex_lock(). SELinux: header generation may hit infinite loop selinux: Fix warnings security: report the module name to security_module_request Config option to set a default LSM sysctl: require CAP_SYS_RAWIO to set mmap_min_addr tpm: autoload tpm_tis based on system PnP IDs tpm_tis: TPM_STS_DATA_EXPECT workaround define convenient securebits masks for prctl users (v2) tpm: fix header for modular build tomoyo: improve hash bucket dispersion tpm add default function definitions LSM: imbed ima calls in the security hooks SELinux: add .gitignore files for dynamic classes security: remove root_plug SELinux: fix locking issue introduced with c6d3aaa4e35c71a3 ...
