Pull perf updates from Ingo Molnar:
 "As a first remark I'd like to note that the way to build perf tooling
  has been simplified and sped up, in the future it should be enough for
  you to build perf via:

        cd tools/perf/
        make install

  (ie without the -j option.) The build system will figure out the
  number of CPUs and will do a parallel build+install.

  The various build system inefficiencies and breakages Linus reported
  against the v3.12 pull request should now be resolved - please
  (re-)report any remaining annoyances or bugs.

   * 'perf trace' enhancements:

      . 'perf trace' now can can use a 'perf probe' dynamic tracepoints
        to hook into the userspace -> kernel pathname copy so that it
        can map fds to pathnames without reading /proc/pid/fd/ symlinks.
        From Arnaldo Carvalho de Melo.

      . Show VFS path associated with fd in live sessions, using a
        'vfs_getname' 'perf probe' created dynamic tracepoint or by

      . Add 'trace' beautifiers for lots of syscall arguments, from

      . 'perf trace' now emits hints as to why tracing is not possible,
        helping the user to setup the system to allow tracing in the
        desired permission granularity, telling if the problem is due to
        debugfs not being mounted or with not enough permission for
        !root, /proc/sys/kernel/perf_event_paranoit value, etc.  From
        Arnaldo Carvalho de Melo.

   * 'perf record' enhancements:

      . Check maximum frequency rate for record/top, emitting better
        error messages, from Jiri Olsa.

      . 'perf record' code cleanups, from David Ahern.

      . Improve write_output error message in 'perf record', from Adrian
        Hunter.

        allowing asking for all possible variables at a given probe
        point to be collected when it hits, from Masami Hiramatsu.

   * 'perf sched' enhancements:

      . Address the root cause of that 'perf sched' stack initialization
        build slowdown, by programmatically setting a big array after
        moving the global variable back to the stack.  Fix from Adrian
        Hunter.

   * 'perf script' enhancements:

There is a race between stop_two_cpus, and the global stop_cpus.

It is possible for two CPUs to get their stopper functions queued
"backwards" from one another, resulting in the stopper threads
getting stuck, and the system hanging. This can happen because
queuing up stoppers is not synchronized.

This patch adds synchronization between stop_cpus (a rare operation),
and stop_two_cpus.

  Right now by far most of the code is related to shmobile updates, and
  they are now switching over to removal of board code and migration to
  multiplatform, so we'll see their board code base shrink in the near
  future too, I hope.

  In addition to that is some defconfig updates, some display updates

  Finally the "shark" platform is removed in this release.  It's been
  abandoned for a while and nobody seems to care enough to keep it
  around.  If someone comes along and wants to resurrect it, the removal
  can easily be reverted and code brought back.

1. copy_insn() doesn't look very nice, all calculations are
   confusing and it is not immediately clear why do we read
   the 2nd page first.

2. The usage of inode->i_size is wrong on 32-bit machines.

3. "Instruction at end of binary" logic is simply wrong, it
   doesn't handle the case when uprobe->offset > inode->i_size.

   In this case "bytes" overflows, and __copy_insn() writes to
   the memory outside of uprobe->arch.insn.

   Yes, uprobe_register() checks i_size_read(), but this file
   can be truncated after that. All i_size checks are racy, we
   do this only to catch the obvious mistakes.

Change copy_insn() to call __copy_insn() in a loop, simplify
and fix the bytes/nbytes calculations.

Note: we do not care if we read extra bytes after inode->i_size
if we got the valid page. This is fine because the task gets the
same page after page-fault, and arch_uprobe_analyze_insn() can't
know how many bytes were actually read anyway.

Commit aa59c53f "uprobes: Change uprobe_copy_process() to dup
xol_area" has a stupid typo, we need to setup t->utask->vaddr but

Even with this bug dup_xol_work() works "in practice", but only
because get_unmapped_area(NULL, TASK_SIZE - PAGE_SIZE) likely
returns the same address every time.

 "Dave Jones's trinity program was able to enable the function tracer

  When I was able to reproduce it with trinity, I was able to track down

  I discovered that the check for whether the function tracepoint should
  be activated or not was using the "perf_paranoid_kernel()" check which
  by default, lets the user continue.  The user should not by default be
  able to enable function tracing.

  The fix is to use "perf_paranoid_tracepoint_raw()" which will not let
  the user enable function tracing.  This is a security fix as normal
  users should never be allowed to enable the function tracer"

STI text console (sticon) was broken on 64bit machines with more than
4GB RAM and this lead in some cases to a kernel crash.

Since sticon uses the 32bit STI API it needs to keep pointers to memory
below 4GB. But on a 64bit kernel some memory regions (e.g. the kernel
stack) might be above 4GB which then may crash the kernel in the STI
functions.

Additionally sticon didn't selected the built-in framebuffer fonts by
default. This is now fixed.

On a side-note: Theoretically we could enhance the sticon driver to
use the 64bit STI API. But - beside the fact that some machines don't
provide a 64bit STI ROM - this would just add complexity.

Install targets (install, zinstall, uinstall) on parisc have a

Install targets "ABSOLUTELY MUST NOT MODIFY THE SOURCE TREE." as Linus
emphasized this in:
