This script can be used to extract vmlinux from a compressed
kernel image (bzImage, etc..). It's inspired from (a subset of)
extract-ikconfig.
It's something a lot of people have been looking for (mainly
people with xen < 4 that doesn't support bzImages at all).

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.

Did this as a merge because of (trivial) conflicts in
- Documentation/feature-removal-schedule.txt
- arch/xtensa/include/asm/uaccess.h
that were just easier to fix up in the merge than in the patch series.
Previous behavior allowed only alphabetic prefixes like pr_info to exceed
the 80 column line length limit.
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
and WARN_ONCE may now exceed 80 cols.

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);

a loop in read_node(). Change the int variable to size_t type as well,

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

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.

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.

follows that advice it could cause problems in the exported header
