David Rientjes 6a108a14fa kconfig: rename CONFIG_EMBEDDED to CONFIG_EXPERT 
The meaning of CONFIG_EMBEDDED has long since been obsoleted; the option
is used to configure any non-standard kernel with a much larger scope than
only small devices.

This patch renames the option to CONFIG_EXPERT in init/Kconfig and fixes
references to the option throughout the kernel.  A new CONFIG_EMBEDDED
option is added that automatically selects CONFIG_EXPERT when enabled and
can be used in the future to isolate options that should only be
considered for embedded systems (RISC architectures, SLOB, etc).

Calling the option "EXPERT" more accurately represents its intention: only
expert users who understand the impact of the configuration changes they
are making should enable it.

This option enables a TX rate control algorithm for
mac80211 that uses a PID controller to select the TX
rate.

default MAC80211_RC_DEFAULT_MINSTREL
---help---
This option selects the default rate control algorithm
mac80211 will use. Note that this default can still be
overridden through the ieee80211_default_rc_algo module
parameter if different algorithms are available.
config MAC80211_RC_DEFAULT_PID
bool "PID controller based rate control algorithm"
depends on MAC80211_RC_PID
---help---
Select the PID controller based rate control as the
default rate control algorithm. You should choose
this unless you know what you are doing.

config MAC80211_MESH
bool "Enable mac80211 mesh networking (pre-802.11s) support"
depends on MAC80211 && EXPERIMENTAL
---help---
This options enables support of Draft 802.11s mesh networking.
The implementation is based on Draft 2.08 of the Mesh Networking
amendment. However, no compliance with that draft is claimed or even
possible, as drafts leave a number of identifiers to be defined after
ratification. For more information visit http://o11s.org/.
config MAC80211_LEDS
bool "Enable LED triggers"
depends on MAC80211
depends on LEDS_CLASS
select LEDS_TRIGGERS
---help---
This option enables a few LED triggers for different
packet receive/transmit events.

bool "Export mac80211 internals in DebugFS"
depends on MAC80211 && DEBUG_FS
---help---
Select this to see extensive information about
the internal state of mac80211 in debugfs.
Say N unless you know you need this.
menuconfig MAC80211_DEBUG_MENU
bool "Select mac80211 debugging features"
depends on MAC80211
---help---
This option collects various mac80211 debug settings.
config MAC80211_NOINLINE
bool "Do not inline TX/RX handlers"
depends on MAC80211_DEBUG_MENU
---help---
This option affects code generation in mac80211, when
selected some functions are marked "noinline" to allow
easier debugging of problems in the transmit and receive
paths.
This option increases code size a bit and inserts a lot
of function calls in the code, but is otherwise safe to
enable.
If unsure, say N unless you expect to be finding problems
in mac80211.
config MAC80211_VERBOSE_DEBUG
bool "Verbose debugging output"
depends on MAC80211_DEBUG_MENU
---help---
Selecting this option causes mac80211 to print out
many debugging messages. It should not be selected
on production systems as some of the messages are
remotely triggerable.
Do not select this option.
config MAC80211_HT_DEBUG
bool "Verbose HT debugging"
depends on MAC80211_DEBUG_MENU
---help---
This option enables 802.11n High Throughput features
debug tracing output.

of the messages are remotely triggerable.
Do not select this option.
config MAC80211_TKIP_DEBUG
bool "Verbose TKIP debugging"
depends on MAC80211_DEBUG_MENU

bool "Verbose powersave mode debugging"
depends on MAC80211_DEBUG_MENU
---help---
Selecting this option causes mac80211 to print out very
verbose power save mode debugging messages (when mac80211
is an AP and has power saving stations.)
It should not be selected on production systems as those
messages are remotely triggerable.
Do not select this option.
config MAC80211_VERBOSE_MPL_DEBUG
bool "Verbose mesh peer link debugging"
depends on MAC80211_DEBUG_MENU
depends on MAC80211_MESH

verbose mesh peer link debugging messages (when mac80211
is taking part in a mesh network).
It should not be selected on production systems as those
messages are remotely triggerable.
Do not select this option.

help
Say Y here to make mac80211 register with the ftrace
framework for the driver API -- you can then see which
driver methods it is calling and which API functions
drivers are calling by looking at the trace.
If unsure, say Y.
