Allow K: entries in MAINTAINERS to match directly against filenames;
either those extracted from patch +++ or --- lines, or those specified
on the command-line using the -f option.

This potentially allows fewer lines in a MAINTAINERS entry, if all the
relevant files are scattered throughout the whole kernel tree, yet
contain some common keyword.  An example would be using an ARM SoC name
as the keyword to catch all related drivers.

I don't think setting exact_pattern_match_hash would be appropriate
here; at least for intended Tegra use case, this feature is to ensure
that all Tegra-related driver changes get Cc'd to the Tegra mailing
list.  Setting exact_pattern_match_hash would prevent git history
parsing for e.g.  S-o-b tags, which still seems like it would be useful.
Hence, this flag isn't set.

Commit ef5da59f ("scripts/kernel-doc: handle struct member
__aligned") permits "char something [123] __aligned(8);".

However, by using \d we constraint ourselves with integers.  This is not
always the case.  In fact, it might be better to do char something[123]
__aligned(sizeof(u16));

For example, With wireless_dev defining:

    u8 address[ETH_ALEN] __aligned(sizeof(u16));

With \d, scripts/kernel-doc erroneously says:

    Warning(include/net/cfg80211.h:2618): Excess struct/union/enum/typedef member 'address' description in 'wireless_dev'

This is because the regex __aligned\s*\(\d+\) fails match at \d as
sizeof is used.

So replace \d with .  to indicate "something" in kernel-doc to ignore
__aligned(SOMETHING) in structs.  With this change, we can use integers
OR sizeof() or macros as we please.

On architectures which have symbol prefixes, depmod emits lots of
warnings like this:

WARNING: $module.ko needs unknown symbol $symbol

This is because depmod isn't being passed the -P <symbol_prefix>
arguments to specify the symbol prefix to ignore. This option is
included since the 3.13 release of module-init-tools.

Update scripts/depmod.sh to take extra arguments for the symbol prefix
(required but may be empty), and update the main Makefile to always pass
"$(CONFIG_SYMBOL_PREFIX)" to scripts/depmod.sh.

If the provided symbol prefix is non-empty, scripts/depmod.sh checks if
depmod --version reports module-init-tools with a version number < 3.13
otherwise it appends -P $SYMBOL_PREFIX to the depmod command line.

Commit 10b63956 which plumbed in UAPI
broke the destination-y functionality of scripts/Makefile.headersinst.

The variable destination-y is used in a := assignment and so is expanded at
declaration time, and the include of the Kbuild fragments that set
destination-y to something is after this time, so it now always expands empty.

There are no in-tree users of destination-y, but it allows any
Kbuild-fragment to redirect where headers are installed.

Just move the assignment of the variable that uses it below the include
of the Kbuild fragment.

'make rpm-pkg' and 'make binrpm-pkg' fail when the kernel source is
read-only.  Specifically, when the RPM spec generated by
scripts/package/mkspec is run, KBUILD_SRC happens to be set to the
source location and thus the invocation of 'make headers_install'
fails when an internal call to 'filechk' tries to write a file into
the source tree.

The fix is to clear KBUILD_SRC for the 'make headers_install'
invocation in the spec file, as is already done for the 'make
modules_install' invocation.

Device tree source files may now include header files. The intent is
that those header files define/name constants used as part of the DT
bindings. Currently this feature is open to abuse, since any kernel
header file at all can be included, This could allow device tree files
to become dependant on kernel headers files, and thus make them no
longer OS-independent. This would also prevent separating the device
tree source files from the kernel repository.

Solve this by limiting the cpp include path for device tree files to
separate directories.

The devm_request_and_ioremap() function is very useful and helps avoid a
whole lot of boilerplate. However, one issue that keeps popping up is
its lack of a specific error code to determine which of the steps that
it performs failed. Furthermore, while the function gives an example and
suggests what error code to return on failure, a wide variety of error
codes are used throughout the tree.

In an attempt to fix these problems, this patch adds a new function that
drivers can transition to. The devm_ioremap_resource() returns a pointer
to the remapped I/O memory on success or an ERR_PTR() encoded error code
on failure. Callers can check for failure using IS_ERR() and determine
its cause by extracting the error code using PTR_ERR().

devm_request_and_ioremap() is implemented as a wrapper around the new
API and return NULL on failure as before. This ensures that backwards
compatibility is maintained until all users have been converted to the
new API, at which point the old devm_request_and_ioremap() function
should be removed.

A semantic patch is included which can be used to convert from the old
devm_request_and_ioremap() API to the new devm_ioremap_resource() API.
Some non-trivial cases may require manual intervention, though.
