Merge branch 'next-general' of git://git.kernel.org/pub/scm/linux/kernel/git/jmorris/linux-security
Pull security subsystem updates from James Morris: "In this patchset, there are a couple of minor updates, as well as some reworking of the LSM initialization code from Kees Cook (these prepare the way for ordered stackable LSMs, but are a valuable cleanup on their own)" * 'next-general' of git://git.kernel.org/pub/scm/linux/kernel/git/jmorris/linux-security: LSM: Don't ignore initialization failures LSM: Provide init debugging infrastructure LSM: Record LSM name in struct lsm_info LSM: Convert security_initcall() into DEFINE_LSM() vmlinux.lds.h: Move LSM_TABLE into INIT_DATA LSM: Convert from initcall to struct lsm_info LSM: Remove initcall tracing LSM: Rename .security_initcall section to .lsm_info vmlinux.lds.h: Avoid copy/paste of security_init section LSM: Correctly announce start of LSM initialization security: fix LSM description location keys: Fix the use of the C++ keyword "private" in uapi/linux/keyctl.h seccomp: remove unnecessary unlikely() security: tomoyo: Fix obsolete function security/capabilities: remove check for -EINVAL
