commit 7373f4f (kbuild: add implicit rules for parser generation)
created a implicit rule chain (%.c: %.c_shipped: %.y).
Make considers the _shipped files to be intermediate files which
causes them to be deleted if they didn't exist before make was run.
Mark the _shipped files PRECIOUS to prevent make from deleting them.

On PowerPC we use _GLOBAL throughout the assembly to define symbols, but
currently these symbols are missing from the tags generated with
ARCH=powerpc make tags. This patch modifies the tags.sh script to
recognise _GLOBAL(.*) so that these symbols will be in the tags.
This is almost (but not quite) PowerPC specific and this change should
not affect anyone else:
$ git grep -E '^_GLOBAL\(([^)]*)\).*' |sed 's/^\([^/]*\/[^/]*\)\/.*$/\1/'|uniq -c

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.

Help text under choice menu is never displayed because it does not have
symbol name associated with it, however many kconfigs have help text
under choice, assuming that it will be displayed when user selects help.
for example in Kconfig if we have:
choice
prompt "Choice"
---help---
HELP TEXT ...
config A
bool "A"
config B
bool "B"
endchoice
Without this patch "HELP TEXT" is not displayed when user selects help
option when "Choice" is highlighted from menuconfig or xconfig or
gconfig.
This patch changes the logic in menu_get_ext_help to display help for
cases which dont have symbol names like choice.

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.

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);

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
