file licenses
Add a file to the Documentation directory to describe how file licenses
should be described in all kernel files, using the SPDX identifier, as well
as where all licenses should be in the kernel source tree for people to
refer to (LICENSES/).
Thanks to Kate and Greg for review and editing and Jonas for the
suggestions concerning the meta tags in the licenses files.

drivers/md/faulty.c has been renamed to md-faulty.c after
following commit merged int to the main line.
935fe0983e09f4f7331ebf5ea4ae2124f6e9f9e8 .
But the file name in fault-injection.txt has not been changed.
Now the actual file name and document are in sync.

- Move errseq.rst into core-api
- Add errseq to the core-api index
- Promote the header to a more prominent header type, otherwise we get three
entries in the table of contents.
- Reformat the table to look nicer and be a little more proportional in
terms of horizontal width per bit (the SF bit is still disproportionately
large, but there's no way to fix that).
- Include errseq kernel-doc in the errseq.rst
- Neaten some kernel-doc markup

There are several places within the Kernel tree with nested
structs/unions, like this one:
struct ingenic_cgu_clk_info {
const char *name;
enum {
CGU_CLK_NONE = 0,
CGU_CLK_EXT = BIT(0),
CGU_CLK_PLL = BIT(1),
CGU_CLK_GATE = BIT(2),
CGU_CLK_MUX = BIT(3),
CGU_CLK_MUX_GLITCHFREE = BIT(4),
CGU_CLK_DIV = BIT(5),
CGU_CLK_FIXDIV = BIT(6),
CGU_CLK_CUSTOM = BIT(7),
} type;
int parents[4];
union {
struct ingenic_cgu_pll_info pll;
struct {
struct ingenic_cgu_gate_info gate;
struct ingenic_cgu_mux_info mux;
struct ingenic_cgu_div_info div;
struct ingenic_cgu_fixdiv_info fixdiv;
};
struct ingenic_cgu_custom_info custom;
};
};
Currently, such struct is documented as:
**Definition**
::
struct ingenic_cgu_clk_info {
const char * name;
};
**Members**
``name``
name of the clock
With is obvioulsy wrong. It also generates an error:
drivers/clk/ingenic/cgu.h:169: warning: No description found for parameter 'enum'
However, there's nothing wrong with this kernel-doc markup: everything
is documented there.
It makes sense to document all fields there. So, add a
way for the core to parse those structs.
With this patch, all documented fields will properly generate
documentation.

`Documentation/i2c/dev-interface` gives examples for accessing i2c from
userspace.
There's a note that warns developers about the two `i2c-dev.h` header
files which were shipped with the kernel and i2c-tools separately.
However, following i2c-tools commits suggest that the header files are now
identical (in functionality) and `i2c_*` helper functions are now defined
in a separate header called `i2c/smbus.h`, which is distributed with
i2c-tools:
commit 652619121974 ("Minimize differences with kernel flavor")
commit 93caf007f4cb ("Move SMBus helper functions to include/i2c/smbus.h")
Thus, I've converted the warning paragraph into a historical note and
updated the suggested header files.

Onewire devices has 6 byte long unique serial numbers, 1 byte family
code and 1 byte CRC. Linux sysfs presents the device folder in the
form of familyID-deviceID, so CRC is not shown. The consequence is
that the device serial number is always a 12 long hex-string, but
doc says 13 in one place. This is corrected by this change.

There is currently very little documentation in the kernel on maintainer
level tasks. In particular there are no documents on creating pull
requests to submit to Linus.
Quoting Greg Kroah-Hartman on LKML:
Anyway, this actually came up at the kernel summit / maintainer
meeting a few weeks ago, in that "how do I make a
good pull request to Linus" is something we need to document.
Here's what I do, and it seems to work well, so maybe we should turn
it into the start of the documentation for how to do it.
(quote references: kernel summit, Europe 2017)
Create a new kernel documentation book 'how to be a maintainer'
(suggested by Jonathan Corbet). Add chapters on 'configuring git' and
'creating a pull request'.
Most of the content was written by Linus Torvalds and Greg Kroah-Hartman
in discussion on LKML. This is stated at the start of one of the
chapters and the original email thread is referenced in
'pull-requests.rst'.

Old kernels did not check for zero in the irq_state.flags field and old
QEMUs did not zero the flag/reserved fields when calling
KVM_S390_*_IRQ_STATE. Let's add comments to prevent future uses of
these fields.

Pull GPIO fixes from Linus Walleij:
"Three small fixes for GPIO. Not much, I'm surprised by the silence in
my subsystems. All driver fixes:
- fix a crash in the 74x164 driver
- fix IRQ banks in the DaVinci driver
- fix the vendor prefix in the PCA953x driver"
* tag 'gpio-v4.15-2' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio:
gpio: pca953x: fix vendor prefix for PCA9654
gpio: davinci: Assign first bank regs for unbanked case
gpio: 74x164: Fix crash during .remove()

Pull documentation fixes from Jonathan Corbet:
"A handful of documentation fixes.
The most significant of these addresses a problem with the new warning
mode: it can break the build when confronted with a source file
containing malformed kerneldoc comments"
* tag 'docs-4.15-fixes' of git://git.lwn.net/linux:
Documentation: fix docs build error after source file removed
scsi: documentation: Fix case of 'scsi_device' struct mention(s)
genericirq.rst: Remove :c:func:`...` in code blocks
dmaengine: doc : Fix warning "Title underline too short" while make xmldocs
scripts/kernel-doc: Don't fail with status != 0 if error encountered with -none

The pci/htirq.c file was removed so remove it from the documentation
file also.
Error: Cannot open file ../drivers/pci/htirq.c
WARNING: kernel-doc '../scripts/kernel-doc -rst -enable-lineno -export ../drivers/pci/htirq.c' failed with return code 2

Pull hwmon fixes from Guenter Roeck:
"Fixes:
- Drop reference to obsolete maintainer tree
- Fix overflow bug in pmbus driver
- Fix SMBUS timeout problem in jc42 driver
For the SMBUS timeout handling, we had a brief discussion if this
should be considered a bug fix or a feature. Peter says "it fixes real
problems where the application misbehave due to faulty content when
reading from an eeprom", and he needs the patch in his company's v4.14
images. This is good enough for me and warrants backport to stable
kernels"
* tag 'hwmon-for-linus-v4.15-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/groeck/linux-staging:
hwmon: (jc42) optionally try to disable the SMBUS timeout
hwmon: (pmbus) Use 64bit math for DIRECT format values
hwmon: Drop reference to Jean's tree
