Subject: [GIT PULL] Security subsystem general updates for 4.15

In this branch are changes for:

TPM:
----

(from Jarkko)

"Contains mostly minor fixes.
 
Selected more essential changes:
 
* Essential clean up for tpm_crb so that ARM64 and x86 versions do not
  distract each other as much as before.
* /dev/tpm0 rejects now too short writes (shorter buffer than specified 
  in the command header.
* Use DMA-safe buffer in tpm_tis_spi."


Smack:
------
- Base support for overlafs


Capabilities:
-------------

- BPRM_FCAPS fixes, from Richard Guy Briggs:

"The audit subsystem is adding a BPRM_FCAPS record when auditing setuid
application execution (SYSCALL execve). This is not expected as it was
supposed to be limited to when the file system actually had capabilities
in an extended attribute.  It lists all capabilities making the event
really ugly to parse what is happening.  The PATH record correctly
records the setuid bit and owner.  Suppress the BPRM_FCAPS record on
set*id."


TOMOYO:
-------
- Y2038 timestamping fixes


I'll push the Integrity susbsytem changes in a separate branch.


Please pull.
