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.Signed-off-by: Anish Bhatt

…it/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 vmeach subsystem directory contains the feature directories. For example locking
has:triton:~/tip> ls Documentation/features/locking/
cmpxchg-local lockdep queued-rwlocks queued-spinlocks rwsem-optimizedIt'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). -

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.Signed-off-by: Krzysztof Kozlowski

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.Fixes: 334c86c494b9 ("MIPS: IRQ: Add stackoverflow detection")

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.

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
log back in. This isn't nice behaviour.Fix it by returning the number of characters written to sysfs files.

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.Cc: stable@vger.kernel.org
