ebf16e3851 Staging: hv: file2alias: fix up alias creation logic for hv_vmbus_device_id
When I added the driver_data field to hv_vmbus_device_id, I forgot to
take into the account how the alias was created, so it would append the
kernel pointer to the end of the alias, which is not correct.

This changes how the hv_vmbus_device_id alias is created to proper
account for the driver_data field.  As no module yet uses this alias, it
is safe to fix this up at this point in the commit stream.

2a11c8ea20 kconfig: Introduce IS_ENABLED(), IS_BUILTIN() and IS_MODULE()
Replace the config_is_*() macros with a variant that allows for grepping
for usage of CONFIG_* options in the code. Usage:

  if (IS_ENABLED(CONFIG_NUMA))

or

  #if IS_ENABLED(CONFIG_NUMA)

The IS_ENABLED() macro evaluates to 1 if the argument is set (to either 'y'
or 'm'), IS_BUILTIN() tests if the option is 'y' and IS_MODULE() test if
the option is 'm'. Only boolean and tristate options are supported.

ath6kl wants to add a digit into the prefix, so allow numbers as well as
digits in the <prefix>_<level> printks.

<prefix>_<level>_ratelimited and <prefix>_<level>_once and WARN_RATELIMIT

000d1cc182 checkpatch.pl: add ability to ignore various messages
Some users would like the ability to not emit some of the messages that
checkpatch produces.  This can make it easier to use checkpatch in other
projects and integrate into scm hook scripts.

Add command line option to "--ignore" various message types.  Add option
--show-types to emit the "type" of each message.  Categorize all ERROR,
WARN and CHK messages with types.

Add optional .checkpatch.conf file to store default options.
3 paths are searched for .checkpatch.conf
    .             customized per-tree configurations
    $HOME         user global configuration when per-tree configs don't exist
    ./scripts     lk defaults to override script
The .conf file can contain any valid command-line argument and
the contents are prepended to any additional command line arguments.
Multiple lines may be used, blank lines are ignored, # is a comment.

Update "false positive" output for readability.

Update version to 0.32

7d2367af0b checkpatch: suggest using min_t or max_t
A common issue with min() or max() is using a cast on one or both of the
arguments when using min_t/max_t could be better.

Add cast detection to uses of min/max and suggest an appropriate use of
min_t or max_t instead.

Caveat:  This only works for min() or max() on a single line.
         It does not find min() or max() split across multiple lines.

This does find:
	min((u32)foo, bar);
But it does not find:
	max((unsigned long)foo,
	    bar);

1ae14703e7 genksyms: Use same type in loop comparison
The ARRAY_SIZE macro in scripts/genksyms/genksyms.c returns a value of
type size_t. That value is being compared to a variable of type int in
a loop in read_node(). Change the int variable to size_t type as well,
so we don't do signed vs unsigned type comparisons with all the
potential promotion/sign extension trouble that can cause (also
silences compiler warnings at high levels of warnings).

62a2635610 modpost: Fix modpost's license checking V3
The commit f02e8a6 sorts symbols placing each of them in its own elf section.
The sorting and merging into the canonical sections are done by the linker.
Unfortunately modpost to generate Module.symvers file parses vmlinux
(already linked) and all modules object files (which aren't linked yet).
These aren't sanitized by the linker yet. That breaks modpost that can't
detect license properly for modules. This patch makes modpost aware of
the new exported symbols structure.

<andersk@ksplice.com> for providing useful suggestions about code.

f98ee76955 kconfig/nconf: prevent segfault on empty menu
nconf does not check the validity of the current menu when help is
requested (with either <F2>, '?' or 'h'). This leads to a NULL pointer
dereference when an empty menu is encountered.

The following reduced testcase exposes the problem:

config DEP
        bool

menu "FOO"

config BAR
        bool "BAR"
        depends on DEP

endmenu

Issue will happen when entering menu "FOO" and requesting help.

nconf is the only front-end which do not filter the validity of the
current menu. Such filter can not really happen beforehand as other key
which does not deals with the current menu might be entered by the user,
so just bails out earlier if we encounter an invalid menu.

5416857867 kconfig/nconf: use the generic menu_get_ext_help()
nconf is the only front-end which does not use this helper, but prefer
to copy/paste the code. The test wrt. menu validity added in this
version of the code is bogus anyway as an invalid menu will get
dereferenced a few line below by calling menu_get_prompt().

For now, convert nconf to use menu_get_ext_help(), as do every other
front-end. We will deals with menu validity checks properly in a
separate commit.

ec6452a5ec kconfig: do not overwrite symbol direct dependency in assignment
Considering the following configuration:

config F
    bool "F"

choice AB
    bool "AB"
config A
    bool "A"
config B
    bool "B"
endchoice

if A
config D
    bool
    default y if F
    select E
config E
    bool "E"
endif

if B
config D
    bool
    default y if F
    select E
config E
    bool "E"
endif

The following configuration:

 CONFIG_F=y
 CONFIG_A=y
 # CONFIG_B is not set
 CONFIG_D=y
 CONFIG_E=y

emits a spurious warning:

(D) selects E which has unmet direct dependencies (B)

If a symbol appears in two different branch of the tree, it should inherit the
dependency of both parent, not just the last one.

f210735fe2 headers_install: fix __packed in exported kernel headers
checkpatch.pl warns about using __attribute__((packed)) in kernel
headers: "__packed is preferred over __attribute__((packed))". If one
follows that advice it could cause problems in the exported header
files, because the outside world doesn't know about this shortcut.

For example busybox will fail to compile:
 CC      miscutils/ubi_attach_detach.o
 In file included from miscutils/ubi_attach_detach.c:27:0:
 /usr/include/mtd/ubi-user.h:330:3: error: conflicting types for ‘__packed’
 /usr/include/mtd/ubi-user.h:314:3: note: previous declaration of ‘__packed’ was here
...

Fix the problem by substituting __packed with __attribute__((packed)) in
the header_install.pl script.

3bdccc880b package: Makefile: fix perf target bug
Specify --git-dir when building perf targets to allow out-of-tree
builds using O=<build-dir>.

The shell command in `git archive' had to be modified to allow proper
file name expansion of the files listed in MANIFEST.

f0f3ca8d96 docproc: cleanup brace placement
The placement of the opening brace "{" after 'if' statements in
scripts/docproc.c is inconsistent. Most are placed on the same line as the 'if'
statement itself as per CodingStyle, but a few are not.  This patch cleans up
the inconsistency. We save a few source lines and the file then uses the same
style throughout, which is nice.

Warn about uses of printk_ratelimit() because it uses a global state and

c443453c6d bootgraph.pl: relax timing information requirements
This patch removes the assumption of the bootgraph.pl script that the
timing information reported by PRINTK_TIME will contain at least one
entry with a time of less than 100 seconds.

Not all boards correctly reset the system timer and in many cases the
inital times reported by PRINTK_TIME is high. When this occurs the
bootchart.pl script fails to give any useful output.

This patch sets the $firsttime variable to the largest value expected
by PRINTK_TIME
