      arm64: fix alignment padding in assembly code · aeed41a9
      Marc Zyngier authored
      An interesting effect of using the generic version of linkage.h
      is that the padding is defined in terms of x86 NOPs, which can have
      even more interesting effects when the assembly code looks like this:
      
      ENTRY(func1)
      	mov	x0, xzr
      ENDPROC(func1)
      	// fall through
      ENTRY(func2)
      	mov	x0, #1
      	ret
      ENDPROC(func2)
      
      Admittedly, the code is not very nice. But having code from another
      architecture doesn't look completely sane either.
      
      The fix is to add arm64's version of linkage.h, which causes the insertion
      of proper AArch64 NOPs.

      use clamp_t in UNAME26 fix · 31fd84b9

      The min/max call needed to have explicit types on some architectures
      (e.g. mn10300). Use clamp_t instead to avoid the warning:

      Merge tag 'perf-urgent-for-mingo' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into perf/urgent
      
      Pull perf/urgent fixes from Arnaldo Carvalho de Melo:
      
      * The python binding needs to link with libtraceevent and to initialize
        the 'page_size' variable so that mmaping works again.
      
      * The callchain folding character that appears on the TUI just before
        the overhead had disappeared due to recent changes, add it back.
      
      * Intel PEBS in VT-x context uses the DS address as a guest linear address,
        even though its programmed by the host as a host linear address. This either
        results in guest memory corruption and or the hardware faulting and 'crashing'
        the virtual machine.  Therefore we have to disable PEBS on VT-x enter and
        re-enable on VT-x exit, enforcing a strict exclude_guest.
      
        Kernel side enforcement fix by Peter Zijlstra, tooling side fix by David Ahern.
      
      * Fix build on sparc due to UAPI, fix from David Miller.
      
      * Fixes for the srclike sort key for unresolved symbols and when processing
        samples in JITted code, where we don't have an ELF file, just an special
        symbol table, fixes from Namhyung Kim.
      
      * Fix some leaks in libtraceevent, from Steven Rostedt.

      MODSIGN: Move the magic string to the end of a module and eliminate the search · caabe240
      David Howells authored
      Emit the magic string that indicates a module has a signature after the
      signature data instead of before it.  This allows module_sig_check() to
      be made simpler and faster by the elimination of the search for the
      magic string.  Instead we just need to do a single memcmp().
      
      This works because at the end of the signature data there is the
      fixed-length signature information block.  This block then falls
      immediately prior to the magic number.
      
      From the contents of the information block, it is trivial to calculate
      the size of the signature data and thus the size of the actual module
      data.
