Commit c3ff2a51 ("powerpc/32: add stack protector support")
caused kernel panic on PowerPC when an external module is used with
CONFIG_STACKPROTECTOR because the 'prepare' target was not executed
for the external module build.

Commit e07db28e ("kbuild: fix single target build for external
module") turned it into a build error because the 'prepare' target is
now executed but the 'prepare0' target is missing for the external
module build.

External module on arm/arm64 with CONFIG_STACKPROTECTOR_PER_TASK is
also broken in the same way.

Move 'PHONY += prepare0' to the common place. GNU Make is fine with
missing rule for phony targets. I also removed the comment which is
wrong irrespective of this commit.

I minimize the change so it can be easily backported to 4.20.x

To fix v4.20, please backport e07db28e ("kbuild: fix single target
build for external module"), and then this commit.

On the failure path, we do an fput() of the listener fd if the filter fails
to install (e.g. because of a TSYNC race that's lost, or if the thread is
killed, etc.). fput() doesn't actually release the fd, it just ads it to a
work queue. Then the thread proceeds to free the filter, even though the
listener struct file has a reference to it.

To fix this, on the failure path let's set the private data to null, so we
know in ->release() to ignore the filter.

The swap_lock used by sbitmap has a chain with locks taken from softirq,
but the swap_lock is not protected from being preempted by softirqs.

A chain exists of:

 sbq->ws[i].wait -> dispatch_wait_lock -> swap_lock

Where the sbq->ws[i].wait lock can be taken from softirq context, which
means all locks below it in the chain must also be protected from
softirqs.

When building using GCC 4.7 or older, -ffunction-sections & the -pg flag
used by ftrace are incompatible. This causes warnings or build failures
(where -Werror applies) such as the following:

  arch/mips/generic/init.c:
    error: -ffunction-sections disabled; it makes profiling impossible

This used to be taken into account by the ordering of calls to cc-option
from within the top-level Makefile, which was introduced by commit
90ad4052 ("kbuild: avoid conflict between -ffunction-sections and
-pg on gcc-4.7"). Unfortunately this was broken when the
CONFIG_LD_DEAD_CODE_DATA_ELIMINATION cc-option check was moved to
Kconfig in commit e85d1d65 ("kbuild: test dead code/data elimination
support in Kconfig"), because the flags used by this check no longer
include -pg.

Fix this by not allowing CONFIG_LD_DEAD_CODE_DATA_ELIMINATION to be
enabled at the same time as ftrace/CONFIG_FUNCTION_TRACER when building
using GCC 4.7 or older.

UNAME26 is a mechanism to report Linux's version as 2.6.x, for
compatibility with old/broken software.  Due to the way it is
implemented, it would have to be updated after 5.0, to keep the
resulting versions unique.  Linus Torvalds argued:

 "Do we actually need this?

  I'd rather let it bitrot, and just let it return random versions. It
  will just start again at 2.4.60, won't it?

  Anybody who uses UNAME26 for a 5.x kernel might as well think it's
  still 4.x. The user space is so old that it can't possibly care about
  differences between 4.x and 5.x, can it?

  The only thing that matters is that it shows "2.4.<largeenough>",
  which it will do regardless"

Pull ARM SoC fixes from Olof Johansson:
 "A bigger batch than I anticipated this week, for two reasons:

   - Some fallout on Davinci from board file -> DTB conversion, that
     also includes a few longer-standing fixes (i.e. not recent
     regressions).

   - drivers/reset material that has been in linux-next for a while, but
     didn't get sent to us until now for a variety of reasons
     (maintainer out sick, holidays, etc). There's a functional
     dependency in there such that one platform (Altera's SoCFPGA) won't
     boot without one of the patches; instead of reverting the patch
     that got merged, I looked at this set and decided it was small
     enough that I'll pick it up anyway. If you disagree I can revisit
     with a smaller set.

  That being said, there's also a handful of the usual stuff:

   - Fix for a crash on Armada 7K/8K when the kernel touches
     PSCI-reserved memory

   - Fix for PCIe reset on Macchiatobin (Armada 8K development board,
     what this email is sent from in fact :)

Pull btrfs fixes from David Sterba:

 - two regression fixes in clone/dedupe ioctls, the generic check
   callback needs to lock extents properly and wait for io to avoid
   problems with writeback and relocation

 - fix deadlock when using free space tree due to block group creation

 - a recently added check refuses a valid fileystem with seeding device,
   make that work again with a quickfix, proper solution needs more
   intrusive changes

Pull driver core fixes from Greg KH:
 "Here is one small sysfs change, and a documentation update for 5.0-rc2

  The sysfs change moves from using BUG_ON to WARN_ON, as discussed in
  an email thread on lkml while trying to track down another driver bug.
  sysfs should not be crashing and preventing people from seeing where
  they went wrong. Now it properly recovers and warns the developer.

  The documentation update removes the use of BUS_ATTR() as the kernel
  is moving away from this to use the specific BUS_ATTR_RW() and friends
  instead. There are pending patches in all of the different subsystems
  to remove the last users of this macro, but for now, don't advertise
  it should be used anymore to keep new ones from being introduced.

  Both have been in linux-next with no reported issues"

Pull staging driver fixes from Greg KH:
 "Here are some small staging driver fixes for some reported issues.

  One reverts a patch that was made to the rtl8723bs driver that turned
  out to not be needed at all as it was a bug in clang. The others fix
  up some reported issues in the rtl8188eu driver and update the
  MAINTAINERS file to point to Larry for this driver so he can get the
  bug reports easier.

  All have been in linux-next with no reported issues"

 "Here are 2 tty and serial fixes for 5.0-rc2 that resolve some reported
  issues.

  The first is a simple serial driver fix for a regression that showed
  up in 5.0-rc1. The second one resolves a number of reported issues
  with the recent tty locking fixes that went into 5.0-rc1. Lots of
  people have tested the second one and say it resolves their issues.

Pull USB fixes from Greg KH:
 "Here are some small USB driver fixes and quirk updates for 5.0-rc2.

  The majority here are some quirks for some storage devices to get them
  to work properly. There's also a fix here to resolve the reported

  really are not.

Late reset controller changes for v5.0

This adds missing deassert functionality to the ARC HSDK reset driver,
fixes some indentation and grammar issues in the kernel docs, adds a
helper to count the number of resets on a device for the non-DT case
as well, adds an early reset driver for SoCFPGA and simple reset driver
support for Stratix10, and generalizes the uniphier USB3 glue layer
reset to also cover AHCI.

mvebu fixes for 5.0

They are all device tree fixes which also worth being in stable:

 - Reserve PSCI area on Armada 7K/8K preventing the kernel accessing
   this area and crashing while doing it.

 - Use correct PCIe reset signal on MACCHIATOBin  (Armada 8040 based)

 - Fix polarity of GPIO fan line D-Link DNS NASes(kikwood based)
