      Pull s390 updates from Heiko Carstens:
       "Since Martin is on vacation you get the s390 pull request for the
        v4.15 merge window this time from me.
      
        Besides a lot of cleanups and bug fixes these are the most important
        changes:
      
         - a new regset for runtime instrumentation registers
      
         - hardware accelerated AES-GCM support for the aes_s390 module
      
         - support for the new CEX6S crypto cards
      
         - support for FORTIFY_SOURCE
      
         - addition of missing z13 and new z14 instructions to the in-kernel
           disassembler
      
         - generate opcode tables for the in-kernel disassembler out of a
           simple text file instead of having to manually maintain those
           tables
      
         - fast memset16, memset32 and memset64 implementations
      
         - removal of named saved segment support
      
         - hardware counter support for z14
      
         - queued spinlocks and queued rwlocks implementations for s390
      
         - use the stack_depth tracking feature for s390 BPF JIT
      
         - a new s390_sthyi system call which emulates the sthyi (store
           hypervisor information) instruction
      
         - removal of the old KVM virtio transport
      
         - an s390 specific CPU alternatives implementation which is used in
           the new spinlock code"

      Pull m68k updates from Greg Ungerer:
       "The bulk of the changes are to support the ColdFire 5441x SoC family
        with their MMU enabled. The parts have been supported for a long time
        now, but only in no-MMU mode.
      
        Angelo Dureghello has a new board with a 5441x and we have ironed out
        the last problems with MMU enabled on it. So there is also some
        changes to properly support that board too.
      
        Also a fix for a link problem when selecting the traditional 68k beep
        device in no-MMU configurations"

        Commit 26ddabfe ("evm: enable EVM when X509 certificate is
        loaded") enabled EVM without loading a symmetric key, but was limited
        to defining the x509 certificate pathname at build. Included in this
        set of patches is the ability of enabling EVM, without loading the EVM
        symmetric key, from userspace. New is the ability to prevent the
        loading of an EVM symmetric key."

        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.

      /proc/module: fix building without kallsyms · e4a8ca3b
      Arnd Bergmann authored
      As reported by kernelci and other build bots, we now get a link
      failure without CONFIG_KALLSYMS:
      
        module.c:(.text+0xf2c): undefined reference to `kallsyms_show_value'
      
      This adds a dummy helper with the same name that can be used
      for compilation. It's not entirely clear to me what this
      should return for !CONFIG_KALLSYMS, I picked an unconditional
      'false', which leads to the module address being unavailable
      to user space.
      
      Link: https://kernelci.org/build/mainline/branch/master/kernel/v4.14-5-g516fb7f2e73d/
      Fixes: 516fb7f2 ("/proc/module: use the same logic as /proc/kallsyms for address exposure")

      kallsyms: fix building without printk · 01c313dd
      Arnd Bergmann authored
      Building kallsyms fails without CONFIG_PRINTK due to a missing
      declaration:
      
        kernel/kallsyms.c: In function 'kallsyms_show_value':
        kernel/kallsyms.c:670:10: error: 'kptr_restrict' undeclared (first use in this function); did you mean 'keyring_restrict'?
      
      This moves the declaration outside of the #ifdef guard, the definition
      is already available without CONFIG_PRINTK.
      
      Fixes: c0f3ea15 ("stop using '%pK' for /proc/kallsyms pointer values")

        between things behaving surprisingly and randconfig, I could've

        - The old driver statement has been added to the kernel docs.

          Sayli Karnic will point out kerneldoc comments that are not actually

        Beyond that, it's mostly simple fixes.

      /proc/module: use the same logic as /proc/kallsyms for address exposure · 516fb7f2
      Linus Torvalds authored
      The (alleged) users of the module addresses are the same: kernel
      profiling.
      
      So just expose the same helper and format macros, and unify the logic.

      modules: make sysfs attribute files readable by owner only · 277642dc
      Linus Torvalds authored
      This code goes back to the historical bitkeeper tree commit 3f7b0672
      ("Module section offsets in /sys/module"), where Jonathan Corbet wanted
      to show people how to debug loadable modules.
      
      See
      
          https://lwn.net/Articles/88052/
      
      from June 2004.
      
      To expose the required load address information, Jonathan added the
      sections subdirectory for every module in /sys/modules, and made them
      S_IRUGO - readable by everybody.
      
      It was a more innocent time, plus those S_IRxxx macro names are a lot
      more confusing than the octal numbers are, so maybe it wasn't even
      intentional.  But here we are, thirteen years later, and I'll just change
      it to S_IRUSR instead.
      
      Let's see if anybody even notices.

      Merge branch 'kallsyms-restrictions' · 9d560410
      Linus Torvalds authored
      Merge /proc/kallsyms pointer value restrictions.
      
      Instead of using %pK, and making it about root access (at the wrong
      time, no less), make the whole choice of whether to show the actual
      pointer value be very explicit to the kallsyms code.
      
      In particular, we can now default to not doing so, and yet avoid
      annoying kernel profiling by actually looking at whether kernel
      profiling is allowed or not (by default it is not).
      
      This is all mostly preparation for the real "let's stop leaking kernel
      addresses" work that Tobin Harding is working on.
      
      Small steps.
      
      * kallsyms-restrictions:
        stop using '%pK' for /proc/kallsyms pointer values

      modpost: detect modules without a MODULE_LICENSE · ba1029c9
      Randy Dunlap authored
      Partially revert commit 2fa36568 ("kbuild: soften MODULE_LICENSE
      check") so that modpost detects modules that do not have a
      MODULE_LICENSE.
      
      Sam's commit also changed the fatal error to a warning, which I am
      leaving as is.
      
      This gives advance notice of when a module has no license and will taint
      the kernel if the module is loaded.
      
      This produces the following warnings on x86_64 allmodconfig:

           otherwise KGDB tries to handle it and crashes.

         - prevent default mapping above 47bit when 5 level page tables are
           enabled
      
         - make the delay calibration optimization work correctly, which had
           the conditionals the wrong way around and was operating on data
           which was not yet updated.
      
         - remove the bogus X86_TRAP_BP trap init from the default IDT init
           table, which broke 32bit int3 handling by overwriting the correct
           int3 setup.
