kbuild : Fix documentation of INSTALL_HDR_PATH

The header install makefile creates an 'include' directory inside
INSTALL_HDR_PATH and appending include to the path results in headers
being installed to include/include.

Don't recommend appending include to the path as makefile already does
this.

Merge branch 'doc/4.2' into docs-next

Merge branch 'core/documentation' of git://git./linux/kernel/git/tip/tip into docs-next

A week late but I managed to complete it all and moved it into Git, for better
structure and easy pulling.

Changes relative to the last submission:

  - Added higher level subsystem directories to collect features by
    subsystem:

      triton:~/tip> ls Documentation/features/
      arch-support.txt  core  debug  io  lib  list-arch.sh  locking  perf  sched  seccomp  time  vm

    each subsystem directory contains the feature directories. For example locking
    has:

      triton:~/tip> ls Documentation/features/locking/
      cmpxchg-local  lockdep  queued-rwlocks  queued-spinlocks  rwsem-optimized

    It's all pretty straightforward to navigate. Advantages are better
    visualization, plus git log is able to list changes per subsystem.

  - Prettified the visualization some more.

  - Improved/corrected the support matrices based on feedback to earlier submissions.

  - Updated the support matrices to today's linux-next, so that by the time this
    shows up in upstream in the next merge window it's really recent.
    Most notably there's a new architecture in linux-next (h8300).

This structure should address all feedback that I got and should minimize the
maintenance overhead (chance of conflicts).

Documentation: ARM: EXYNOS: Describe boot loaders interface

Various boot loaders for Exynos based boards use certain memory
addresses during booting for different purposes. Mostly this is one of
following :
1. as a CPU boot address,
2. for storing magic cookie related to low power mode (AFTR, sleep).

The document, based solely on kernel source code, tries to group the
information scattered over different files. This would help in the
future when adding support for new SoC or when extending features
related to low power modes.

MIPS: Fix enabling of DEBUG_STACKOVERFLOW

Commit 334c86c494b9 ("MIPS: IRQ: Add stackoverflow detection") added
kernel stack overflow detection, however it only enabled it conditional
upon the preprocessor definition DEBUG_STACKOVERFLOW, which is never
actually defined. The Kconfig option is called DEBUG_STACKOVERFLOW,
which manifests to the preprocessor as CONFIG_DEBUG_STACKOVERFLOW, so
switch it to using that definition instead.

iscsi_ibft: filter null v4-mapped v6 addresses

I've had reports of UEFI platforms failing iSCSI boot in various
configurations, that ended up being caused by network initialization
scripts getting tripped up by unexpected null addresses (0.0.0.0) being
reported for gateways, dhcp servers, and dns servers.

The tianocore EDK2 iSCSI driver generates an iBFT table that always uses
IPv4-mapped IPv6 addresses for the NIC structure fields.  This results
in values that are "not present or not specified" being reported as
::ffff:0.0.0.0 rather than all zeros as specified.

The iscsi_ibft module filters unspecified fields from the iBFT from
sysfs, preventing userspace from using invalid values and making it easy
to check for the presence of a value.  This currently fails in regard to
these mapped null addresses.

In order to remain consistent with how the iBFT information is exposed,
we should accommodate the behavior of the tianocore iSCSI driver as it's
already in the wild in a large number of servers.

Tested under qemu using an OVMF build of tianocore EDK2.

drm: fix writing to /sys/class/drm/*/status

Writing to a file is supposed to return the number of bytes written.
Returning zero unfortunately causes bash to constantly spin trying
to write to the sysfs file, to such an extent that even ^c and ^z
have no effect.  The only way out of that is to kill the shell and

USB-serial fixes for v4.1-rc7

Here are a couple of new device ids.

Signed-off-by: Johan Hovold <johan@kernel.org>

Input: alps - do not reduce trackpoint speed by half

On some v7 devices (e.g. Lenovo-E550) the deltas reported are typically
only in the 0-1 range dividing this by 2 results in a range of 0-0.

And even for v7 devices where this does not lead to making the trackstick
entirely unusable, it makes it twice as slow as before we added v7 support
and were using the ps/2 mouse emulation of the dual point setup.

If some kind of generic slowdown is actually necessary for some devices,
then that belongs in userspace, not in the kernel.

Documentation: extend use case for EXPORT_SYMBOL_GPL()

Current documentation over use case for EXPORT_SYMBOL_GPL()
only acknowledges functions which are "an internal implementation
issue, and not really an interface". In practice these days
though we have some maintainers taking on preferences to require
all new functionality go in with EXPORT_SYMBOL_GPL().

A maintainer asking developers to use EXPORT_SYMBOL_GPL()
for new functionality tends to be a well accepted and understood
position that maintainers can take and typically requires the
maintainers educating contributing developers on their own
positions and requirements.

Developers who submit code to maintainers not familiar with
these preferences as optional for new functionality need explicit
guidence though as existing documentation does not acknowledge
this as a valid possibility. Without this being documented some
maintainers are reluctant to accept new functionality with
EXPORT_SYMBOL_GPL().

This extends the use case documentation for EXPORT_SYMBOL_GPL()
to acknowledge acceptance for new functionality.

compat: cleanup coding in compat_get_bitmap() and compat_put_bitmap()

In the functions compat_get_bitmap() and compat_put_bitmap() the
variable nr_compat_longs stores how many compat_ulong_t words should be
copied in a loop.

The copy loop itself is this:
  if (nr_compat_longs-- > 0) {
      if (__get_user(um, umask)) return -EFAULT;
  } else {
      um = 0;
  }

Since nr_compat_longs gets unconditionally decremented in each loop and
since it's type is unsigned this could theoretically lead to out of
bounds accesses to userspace if nr_compat_longs wraps around to
(unsigned)(-1).

Although the callers currently do not trigger out-of-bounds accesses, we
should better implement the loop in a safe way to completely avoid such
warp-arounds.

Documentation/features: Explain kernel feature descriptions and add visualization script

The previous patches added arch support matrices for more than 40 generic kernel features
that need per architecture support.

The structure of the feature descriptions is the following:

Each feature has its own directory under Documentation/features/subsystem_name/feature_name/,
and the arch-support.txt file shows its current arch porting status.

For example, lockdep support is shown the following way:

    triton:~/tip> cat Documentation/features/locking/lockdep/arch-support.txt
    #
    # Feature name:          lockdep

For generic kernel features that need architecture support, the
arch-support.txt file in each feature directory shows the arch
support matrix, for all upstream Linux architectures.

The meaning of entries in the tables is:

    | ok |  # feature supported by the architecture
    |TODO|  # feature not yet supported by the architecture
    | .. |  # feature cannot be supported by the hardware

This directory structure can be used in the future to add other
files - such as porting guides, testing description, etc.

The Documentation/features/ hierarchy may also include generic
kernel features that works on every architecture, in that case
the arch-support.txt file will list every architecture as
supported.

To list an architecture's unsupported features, just do something
like:

  triton:~/tip>  git grep -lE 'x86.*TODO' Documentation/features/*/*/arch-support.txt
  Documentation/features/lib/strncasecmp/arch-support.txt
  Documentation/features/time/arch-tick-broadcast/arch-support.txt

which will print the list of not yet supported features.

The Documentation/features/list-arch.sh script will print the current
support matrix of one architecture:

  triton:~/tip> Documentation/features/list-arch.sh
