For pre-4.6.0 versions of GCC, which don't have '-mfentry', the
'-maccumulate-outgoing-args' option is required for function graph
tracing in order to avoid GCC bug 42109.

However, GCC ignores '-maccumulate-outgoing-args' when '-Os' is
also set.

Currently we force a build error to prevent that scenario, but that
breaks randconfigs.  So change the error to a warning which also
disables CONFIG_CC_OPTIMIZE_FOR_SIZE.

On x86-32, with CONFIG_FIRMWARE and multiple CPUs, if you enable function
graph tracing and then suspend to RAM, it will triple fault and reboot when
it resumes.

The first fault happens when booting a secondary CPU:

startup_32_smp()
  load_ucode_ap()
    prepare_ftrace_return()
      ftrace_graph_is_dead()
        (accesses 'kill_ftrace_graph')

The early head_32.S code calls into load_ucode_ap(), which has an an
ftrace hook, so it calls prepare_ftrace_return(), which calls
ftrace_graph_is_dead(), which tries to access the global
'kill_ftrace_graph' variable with a virtual address, causing a fault
because the CPU is still in real mode.

The fix is to add a check in prepare_ftrace_return() to make sure it's
running in protected mode before continuing.  The check makes sure the
stack pointer is a virtual kernel address.  It's a bit of a hack, but
it's not very intrusive and it works well enough.

For reference, here are a few other (more difficult) ways this could
have potentially been fixed:

- Move startup_32_smp()'s call to load_ucode_ap() down to *after* paging
  is enabled.  (No idea what that would break.)

- Track down load_ucode_ap()'s entire callee tree and mark all the
  functions 'notrace'.  (Probably not realistic.)

- Pause graph tracing in ftrace_suspend_notifier_call() or bringup_cpu()
  or __cpu_up(), and ensure that the pause facility can be queried from
  real mode.

memory, double a free or any combination of those.

vdso_enabled can be set to arbitrary integer values via the kernel command
line 'vdso32=' parameter or via 'sysctl abi.vsyscall32'.

load_vdso32() only maps VDSO if vdso_enabled == 1, but ARCH_DLINFO_IA32
merily checks for vdso_enabled != 0. As a consequence the AT_SYSINFO_EHDR
auxiliary vector for the VDSO_ENTRY is emitted with a NULL pointer which
causes a segfault when the application tries to use the VDSO.

Restrict the valid arguments on the command line and the sysctl to 0 and 1.

We should be detaching the MMU before destroying the address

adreno_gpu_cleanup() because it needs access to structs
in adreno_gpu.c.  Plus it is better symmetry to have
the attach and detach at the same code level.

A recent commit introduces a bug in dsi_mgr_phy_enable. In the non

since master and slave DSI exist only in dual DSI mode. For the normal
mode of operation, we should simply reset the PHY of the DSI device
(i.e. msm_dsi) corresponding to the current bridge.

Usage of the wrong DSI pointer also resulted in a static checker
warning. That too is resolved with this fix.

  While fixing the memcpy bug we noticed some other issues with our
  get_user() and put_user() functions, e.g. nested faults may return
  wrong data. This is now fixed by a common fixup handler for
  get_user/put_user in the exception handler which additionally makes
  generated code smaller and faster.

  The third patch is a trivial one-line fix for a patch which went in
  during 4.11-rc and which avoids stalled CPU warnings after power
  shutdown (for parisc machines which can't plug power off themselves).

  USB: fix linked-list corruption in rh_call_control()

Pull tty/serial fixes from Greg KH:
 "Here are some small fixes for some serial drivers and Kconfig help
  text for 4.11-rc5. Nothing major here at all, a few things resolving
  reported bugs in some random serial drivers.

  I don't think these made the last linux-next due to me getting to them
  yesterday, but I am not sure, they might have snuck in. The patches
  only affect drivers that the maintainers of sent me these patches for,
  so we should be safe here :)"

Pull ACPI fixes from Rafael Wysocki:
 "These fix two issues related to IOAPIC hotplug, an overzealous build
  optimization that prevents the function graph tracer from working with
  the ACPI subsystem correctly and an RCU synchronization issue in the
  ACPI APEI code.

  Specifics:

   - drop the unconditional setting of the '-Os' gcc flag from the ACPI
     Makefile to make the function graph tracer work correctly with the
     ACPI subsystem (Josh Poimboeuf).

   - add missing synchronize_rcu() to ghes_remove() which removes an
     element from an RCU-protected list, but fails to synchronize it
     properly afterward (James Morse).

   - fix two problems related to IOAPIC hotplug, a local variable
     initialization in setup_res() and the creation of platform device
     objects for IO(x)APICs which are (a) unused and (b) leaked on
     hot-removal (Joerg Roedel)"

Pull power management fixes from Rafael Wysocki:
 "These fix a cpufreq core issue with the initialization of the cpufreq
  sysfs interface and a cpuidle powernv driver initialization issue.

  Specifics:

   - symbolic links from CPU directories to the corresponding cpufreq
     policy directories in sysfs are not created during initialization
     in some cases which confuses user space, so prevent that from
     happening (Rafael Wysocki).

   - the powernv cpuidle driver fails to pass a correct cpumaks to the
     cpuidle core in some cases which causes subsequent failures to
     occur, so fix it (Vaidyanathan Srinivasan)"
