When we use one of:

  [acme@jouet linux]$ make help | grep perf
    perf-tar-src-pkg    - Build perf-4.14.0-rc3.tar source tarball
    perf-targz-src-pkg  - Build perf-4.14.0-rc3.tar.gz source tarball

    perf-tarxz-src-pkg  - Build perf-4.14.0-rc3.tar.xz source tarball
  [acme@jouet linux]$

I.e. when we create a detached tarball to build perf outside outside the
enveloping kernel sources (from a kernel tarball or a checked out
linux.git directory) we by definition can't check for differences among
the tools/{include,arch}, etc files we originally copied from the
kernel, so bail out in that case, to avoid warnings when doing the
detached builds.

We want to wait for all potentially preempted kprobes trampoline
execution to have completed. This guarantees that any freed
trampoline memory is not in use by any task in the system anymore.
synchronize_rcu_tasks() gives such a guarantee, so use it.

Also, this guarantees to wait for all potentially preempted tasks
on the instructions which will be replaced with a jump.

Since this becomes a problem only when CONFIG_PREEMPT=y, enable
CONFIG_TASKS_RCU=y for synchronize_rcu_tasks() in that case.

This introduces a "register private expedited" membarrier command which
allows eventual removal of important memory barrier constraints on the
scheduler fast-paths. It changes how the "private expedited" membarrier
command (new to 4.14) is used from user-space.

This new command allows processes to register their intent to use the
private expedited command.  This affects how the expedited private
command introduced in 4.14-rc is meant to be used, and should be merged
before 4.14 final.

Processes are now required to register before using
MEMBARRIER_CMD_PRIVATE_EXPEDITED, otherwise that command returns EPERM.

This fixes a problem that arose when designing requested extensions to
sys_membarrier() to allow JITs to efficiently flush old code from
instruction caches.  Several potential algorithms are much less painful
if the user register intent to use this functionality early on, for
example, before the process spawns the second thread.  Registering at
this time removes the need to interrupt each and every thread in that
process at the first expedited sys_membarrier() system call.
