kconfig: make allnoconfig disable options behind EMBEDDED and EXPERT
"make allnoconfig" exists to ease testing of minimal configurations.
Documentation/SubmitChecklist includes a note to test with allnoconfig.
This helps catch missing dependencies on common-but-not-required
functionality, which might otherwise go unnoticed.
However, allnoconfig still leaves many symbols enabled, because they're
hidden behind CONFIG_EMBEDDED or CONFIG_EXPERT. For instance, allnoconfig
still has CONFIG_PRINTK and CONFIG_BLOCK enabled, so drivers don't
typically get build-tested with those disabled.
To address this, introduce a new Kconfig option "allnoconfig_y", used on
symbols which only exist to hide other symbols. Set it on CONFIG_EMBEDDED
(which then selects CONFIG_EXPERT). allnoconfig will then disable all the
symbols hidden behind those.

mac80211: support DTPC IE (from Cisco Client eXtensions)
Linux already supports 802.11h, where the access point can tell the
client to reduce its transmission power. However, 802.11h is only
defined for 5 GHz, where the need for this is much smaller than on
2.4 GHz.
Cisco has their own solution, called DTPC (Dynamic Transmit Power
Control). Cisco APs on a controller sometimes but not always send
802.11h; they always send DTPC, even on 2.4 GHz. This patch adds support
for parsing and honoring the DTPC IE in addition to the 802.11h
element (they do not always contain the same limits, so both must
be honored); the format is not documented, but very simple.
Tested (on top of wireless.git and on 3.16.1) against a Cisco Aironet
1142 joined to a Cisco 2504 WLC, by setting various transmit power
levels for the given access points and observing the results.
The Wireshark 802.11 dissector agrees with the interpretation of the

kconfig: do not special-case 'MODULES' symbol
Currently, the 'MODULES' symbol is hard-coded to be the default symbol
that enables/disables tristates, if no other symbol was declared with
'option modules'.
While this used to be needed for the Linux kernel, we now have an
explicit 'option modules' attached to the 'MODULES' symbol (since
cset
11097a036), so we no longer need to special-case it in the
kconfig code.
Furthermore, kconfig is extensively used out of the Linux kernel, and
other projects may have another meaning for a symbol named 'MODULES'.
This patch changes the way we enable/disable tristates: if a symbol was
found with 'option modules' attached to it, then that symbol controls
enabling tristates. Otherwise, tristates are disabled, even if a symbol
named 'MODULES' exists.

kconfig: silence warning when parsing auto.conf when a symbol has changed type
When a symbol changes type from tristate to bool, and was previously set to
'm', a subsequent silentoldconfig would warn about inconsistency, such as:
include/config/auto.conf:3014:warning: symbol value 'm' invalid for
HOTPLUG_PCI_PCIE
Seen by Linus with the merge in
aa8032b (sequence to reproduce by Michal):
git checkout
1fe0135
make mrproper
make allmodconfig
make silentoldconfig
git checkout
aa8032b
make allmodconfig
make silentoldconfig
Since HOTPLUG_PCI_PCIE changed from tristate to bool in
aa8032b, it was
previously set to 'm' in auto.conf by the first allmodconfig+silentoldconfig,
but then was set to 'y' by the second allmodconfig. Then the second
silentoldconfig prints the warning.
The warning in this case is a spurious warning, which happens at the time
kconfig tries to detect symbols that have changed, to touch the empty
header files in include/config used for dependency-tracking by make.
Silence the warning when we read the old auto.conf file, since it is
perfectly legit that a symbol changed type since the previous call.

Console input/output is redirected. Run 'make oldconfig' to update
configuration.
Fix this by looping in randconfig for as long as some symbol gets assigned

Note: this was spotted with the USB EHCI Debug Device Gadget (USB_G_DBGP),

if A

bool "B/C/D"
config B
bool "B"
config C

shown below for brevity), and where only the right-most .config is valid:

CONFIG_B=y CONFIG_B=y CONFIG_B=y
CONFIG_C=y # CONFIG_C is not set # CONFIG_C is not set
# CONFIG_D is not set CONFIG_D=y # CONFIG_D is not set
That is, in a randomised choice, the first symbol is always selected,
and at most one other symbol may be selected.
This is due to symbol randomised in a choice not being properly flagged
as having a value.
Fix that by flagging those symbols adequately: have a user-defined value,
and be not valid (to force recalculation of the symbol).
Note: if the choice is not conditional, then the randomisation is properly
done.

kconfig/menu.c: fix multiple references to expressions in menu_add_prop()
menu_add_prop() applies upper menus' visibilities to actual prompts
by AND-ing the prompts visibilities with the upper menus ones.
This creates a further reference to the menu's visibilities and when
the expression reduction functions do their work, they may remove or
modify expressions that have multiple references, thus causing
unpredictable side-effects.
The following example Kconfig constructs a case where this causes
problems: a menu and a prompt which's visibilities depend on the same
symbol. When invoking mconf with this Kconfig and pressing "Z" we
see a problem caused by a free'd expression still referenced by the
menu's visibility:

config VISIBLE
def_bool n
config Placeholder
bool "Place holder"
menu "Invisible"
visible if VISIBLE
config TEST_VAR
bool "Test option" if VISIBLE

visibility expressions before AND-ing them with the prompt's one.

bool "Option B"
config OPTION_C

menuconfig: fix NULL pointer dereference when searching a symbol
Searching for PPC_EFIKA results in a segmentation fault, and it's
because get_symbol_prop() returns NULL.
In this case CONFIG_PPC_EFIKA is defined in arch/powerpc/platforms/
52xx/Kconfig, so it won't be parsed if ARCH!=PPC, but menuconfig knows
this symbol when it parses sound/soc/fsl/Kconfig:
config SND_MPC52xx_SOC_EFIKA
tristate "SoC AC97 Audio support for bbplan Efika and STAC9766"
depends on PPC_EFIKA

kconfig: fix randomising choice entries in presence of KCONFIG_ALLCONFIG
Currently, randconfig does randomise choice entries, unless KCONFIG_ALLCONFIG
is specified.
For example, given those two files (Thomas' test-case):
---8<--- Config.test.in
config OPTIONA
bool "Option A"
choice
prompt "This is a choice"
config CHOICE_OPTIONA
bool "Choice Option A"
config CHOICE_OPTIONB
bool "Choice Option B"
endchoice
config OPTIONB
bool "Option B"
---8<--- Config.test.in
---8<--- config.defaults
CONFIG_OPTIONA=y
---8<--- config.defaults
And running:
./config/conf --randconfig Config.test.in
does properly randomise the two choice symbols (and the two booleans).
However, running:
KCONFIG_ALLCONFIG=config.defaults \
./config/conf --randconfig Config.test.in
does *not* reandomise the two choice entries, and only CHOICE_OPTIONA
will ever be selected. (OPTIONA will always be set (expected), and
OPTIONB will be be properly randomised (expected).)
This patch defers setting that a choice has a value until a symbol for
that choice is indeed set, so that choices are properly randomised when
KCONFIG_ALLCONFIG is set, but not if a symbol for that choice is set.
Also, as a side-efect, this patch fixes the following case:
---8<---
choice
config OPTION_A
bool "Option A"
config OPTION_B
bool "Option B"

# CONFIG_OPTION_C is not set CONFIG_OPTION_C=y
---8<--- ---8<---

sym_get_type(sym) always return boolean for tristates when modules_sym
