kgdb: allow static kgdbts boot configuration

This patch adds in the ability to compile the kgdb internal test string into the kernel so as to run the tests at boot without changing the kernel boot arguments. This patch also changes all the error paths to invoke WARN_ON(1) which will emit the line number of the file and dump the kernel stack when an error occurs. You can disable the tests in a kernel that is built this way using "kgdbts=" Signed-off-by: Jason Wessel <jason.wessel@windriver.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>

-
-    Driver for Asus OLED display present in some Asus laptops.
-
-    The code of this driver is based on 'asusoled' program taken from
-    <http://lapsus.berlios.de/asus_oled.html>. I just wanted to have a simple
-    kernel driver for controlling this device, but I didn't know how
-    to do that. Now I know ;) Also, that program can not be used
-    with usbhid loaded, which means no USB mouse/keyboard while
-    controlling OLED display :(
-
-    It has been tested on Asus G1 and didn't cause any problems,
-    but I don't guarantee that it won't do anything wrong :)
-
-    It can (and probably does) have errors. It is usable
-    in my case, and I hope others will find it useful too!
-
-*******
-
-Building the module
-
-   To build the module you need kernel 2.6 include files and some C compiler.
-
-   Just run:
-   make
-   make install (as a root)
-
-   It will build (hopefully) the module and install it in
-   /lib/modules/'uname -r'/extra/asus_oled.ko.
-
-   To load it just use:
-   modprobe asus_oled
-
-   You can check if it has detected your OLED display by looking into dmesg output.
-   There should be something like this:
-   asus-oled 2-7:1.0: Attached Asus OLED device
-
-   If it doesn't find your display, you can try removing usbhid module.
-   If you add asus_oled into the list of modules loaded during system boot
-   before usbhid, it will work even when usbhid is present.
-
-   If it still doesn't detect your hardware, check lsusb output.
-   There should be similar line:
-   Bus 002 Device 005: ID 0b05:1726 ASUSTek Computer, Inc.
-
-   If you don't see any lines with '0b05:1726' it means that you have different
-   type of hardware that is not detected (it may or may not work, but the driver
-   knows only '0b05:1726' device).
-
-*******
-
-Configuration
-
-   There is only one option: start_off.
-   You can use it by: 'modprobe asus_oled start_off=1', or by adding this
-   line to /etc/modprobe.d/asus_oled.conf:
-   options asus_oled start_off=1
-
-   With this option provided, asus_oled driver will switch off the display
-   when it is detected and attached. It is nice feature to just switch off the 'ASUS'
-   logo. If you don't use the display, it is probably the good idea to switch it off,
-   to protect OLEDs from "wearing off".
-
-*******
-
-Usage
-
-   This module can be controlled with two special files:
-   /sys/class/asus_oled/oled_N/enabled
-   /sys/class/asus_oled/oled_N/picture
-
-   (N is the device number, the first, and probably the only, has number 1,
-    so it is /sys/class/asus_oled/oled_1/enabled
-    and /sys/class/asus_oled/oled_1/picture)
-
-   'enabled' files is for reading and writing, 'picture' is writeable only.
-
-   You can write 0 or 1 to 'enabled' file, which will switch
-   on and off the display. Reading from this file will tell you the last
-   status set, either 0 or 1. By default it is 1, so if the device was set to 'off',
-   and the computer was rebooted without power-off, this file will contain wrong
-   value - because the device is off, but hasn't been disabled this time and is
-   assumed to be on...
-
-   To 'picture' file you write pictures to be displayed by the OLED device.
-   The format of the file:
-   <M:WxH>
-   00001110010111000
-   00010101010101010
-   ....
-
-   First line is a configuration parameter. Meaning of fields in <M:WxH>:
-   M - picture mode. It can be either 's' for static pictures,
-       'r' for rolling pictures, and 'f' for flashing pictures.
-   W - width of the picture. May be between 1 and 1792
-   H - height of the picture. May be between 1 and 32
-
-   For example <s:128x32> means static picture, 128 pixels long and 32 pixels high.
-
-   The physical size of the display is 128x32 pixels. Static and flashing pictures
-   can't be larger than that (actually they can, but only part of them will be displayed ;) )
-
-   If the picture is smaller than 128x32 it will be centered. Rolling pictures wider than
-   128 pixels will be centered too, unless their width = n*128. Vertically they will be
-   centered just like static pictures, if their height is smaller than 32.
-
-   Flashing pictures will be centered horizontally if their width < 128, but they were
-   centered vertically in a different way. If their height < 16, they will be centered
-   in the upper half of the display (rows 0-15). This is because only the first half
-   of flashing pictures is used for flashing. When the picture with heigh = 32 is
-   displayed in flashing mode, its upper 16 rows will be flashing in the upper half
-   of the display, and the lower half will be empty. After few seconds upper part will
-   stop flashing (but that part of the picture will remain there), and the lower
-   half of the display will start displayin the lower half of the picture
-   in rolling mode, unless it is empty, or the picture was small enough to fit in
-   upper part. It is not mine idea, this is just the way Asus' display work ;)
-   So if you need just flashing, use at most 128x16 picture. If you need flashing and
-   rolling, use whole size of the display.
-
-   Lines following the first, configuration, line are picture data. Each '1' means
-   that the pixel is lit, and '0' means that it is not. You can also use '#' as ON,
-   and ' ' (space) as OFF. Empty lines and all other characters are ignored.
-
-   It is possible to write everything in one line <M:WxH>01010101010101010...,
-   and W*H characters will be used. If there is not enough characters, nothing will be
-   displayed. However, the 'line mode' is easier to read (and write), and it also
-   lets to omit parts of data. Whenever End-Of-Line character is found, but
-   the line is not W characters long, it is assumed that all missing characters
-   are equal to the last character in the line.
-
-   Following line represents '0', '1' and a lots of '0's, dependng on the width of the picture
-   provided in configuration data:
-   010
-
-   So if you need empty line, it is sufficient to write line with only one '0' in it.
-   The same works with '1' (or ' ' and '#').
-
-   If there are too many data in the file, they will be ignored. If you are not sure
-   how many characters you are missing, you can add few lines with one zero in each of them.
-
-   There are some example pictures in .txt format, that can be used as follows:
-   cat foo.txt > /sys/class/asus_oled/oled_1/picture
-
-   If the display is switched off you also need to run:
-   echo 1 > /sys/class/asus_oled/oled_1/enabled
-   To switch it off, just use:
-   echo 0 > /sys/class/asus_oled/oled_1/enabled
-

-	  The Configurable Composite Gadget supports multiple USB
-	  functions: acm, mass storage, rndis and FunctionFS.
-	  Each function can be configured and enabled/disabled
-	  dynamically from userspace through a sysfs interface.
-
-	  In order to compile this (either as a module or built-in),
-	  "USB Gadget Drivers" and anything under it must not be
-	  selected compiled-in in
-	  Device Drivers->USB Support->USB Gadget Support.
-	  However, you can say "M" there, if you do, the
-	  Configurable Composite Gadget can be compiled "M" only
-	  or not at all.
-
-	  BIG FAT NOTE: DON'T RELY ON THIS USERINTERFACE HERE! AS PART
-	  OF THE REWORK DONE HERE WILL BE A NEW USER INTERFACE WITHOUT ANY
-	  COMPATIBILITY TO THIS SYSFS INTERFACE HERE. BE AWARE OF THIS
-	  BEFORE SELECTING THIS.

- *	and by language IDs provided in control requests
- * @descriptors: Table of full (or low) speed descriptors, using interface and
- *	string identifiers assigned during @bind().  If this pointer is null,
- *	the function will not be available at full speed (or at low speed).
- * @hs_descriptors: Table of high speed descriptors, using interface and

- * @ss_descriptors: Table of super speed descriptors, using interface and
- *	string identifiers assigned during @bind(). If this
- *	pointer is null after initiation, the function will not
- *	be available at super speed.
- * @config: assigned when @usb_add_function() is called; this is the
- *	configuration with which this function is associated.
- * @bind: Before the gadget can register, all of its functions bind() to the
- *	available resources including string and interface identifiers used
- *	in interface or class descriptors; endpoints; I/O buffers; and so on.
- * @unbind: Reverses @bind; called as a side effect of unregistering the
- *	driver which added this function.
- * @set_alt: (REQUIRED) Reconfigures altsettings; function drivers may
- *	initialize usb_ep.driver data at this time (when it is used).
- *	Note that setting an interface to its current altsetting resets
- *	interface state, and that all interfaces have a disabled state.
- * @get_alt: Returns the active altsetting.  If this is not provided,
- *	then only altsetting zero is supported.
- * @disable: (REQUIRED) Indicates the function should be disabled.  Reasons
- *	include host resetting or reconfiguring the gadget, and disconnection.
- * @setup: Used for interface-specific control requests.
- * @suspend: Notifies functions when the host stops sending USB traffic.
- * @resume: Notifies functions when the host restarts USB traffic.
- * @get_status: Returns function status as a reply to
- *	GetStatus() request when the recepient is Interface.
- * @func_suspend: callback to be called when
- *	SetFeature(FUNCTION_SUSPEND) is reseived
- *
- * A single USB function uses one or more interfaces, and should in most
- * cases support operation at both full and high speeds.  Each function is
- * associated by @usb_add_function() with a one configuration; that function
- * causes @bind() to be called so resources can be allocated as part of
- * setting up a gadget driver.  Those resources include endpoints, which
- * should be allocated using @usb_ep_autoconfig().
- *
- * To support dual speed operation, a function driver provides descriptors
- * for both high and full speed operation.  Except in rare cases that don't
- * involve bulk endpoints, each speed needs different endpoint descriptors.
- *
- * Function drivers choose their own strategies for managing instance data.
- * The simplest strategy just declares it "static', which means the function
- * can only be activated once.  If the function needs to be exposed in more
- * than one configuration at a given speed, it needs to support multiple
- * usb_function structures (one for each configuration).
- *
- * A more complex strategy might encapsulate a @usb_function structure inside
- * a driver-specific instance structure to allows multiple activations.  An
- * example of multiple activations might be a CDC ACM function that supports
- * two or more distinct instances within the same configuration, providing
- * several independent logical data links to a USB host.

- * Configurations are building blocks for gadget drivers structured around
- * function drivers.  Simple USB gadgets require only one function and one
- * configuration, and handle dual-speed hardware by always providing the same
- * functionality.  Slightly more complex gadgets may have more than one
- * single-function configuration at a given speed; or have configurations
- * that only work at one speed.
- *
- * Composite devices are, by definition, ones with configurations which
- * include more than one function.
- *
- * The lifecycle of a usb_configuration includes allocation, initialization
- * of the fields described above, and calling @usb_add_config() to set up
- * internal data and bind it to a specific device.  The configuration's
- * @bind() method is then used to initialize all the functions and then
- * call @usb_add_function() for them.
- *
- * Those functions would normally be independent of each other, but that's

- * On success, this returns an un-claimed usb_ep, and modifies the endpoint
- * descriptor bEndpointAddress.  For bulk endpoints, the wMaxPacket value
- * is initialized as if the endpoint were used at full speed and
- * the bmAttribute field in the ep companion descriptor is
- * updated with the assigned number of streams if it is

- *	size must also be initialized.  This is modified on success.
- *
- * By choosing an endpoint to use with the specified descriptor, this
- * routine simplifies writing gadget drivers that work with multiple
- * USB device controllers.  The endpoint would be passed later to
- * usb_ep_enable(), along with some descriptor.
- *
- * That second descriptor won't always be the same as the first one.
- * For example, isochronous endpoints can be autoconfigured for high
- * bandwidth, and then used in several lower bandwidth altsettings.
- * Also, high and full speed descriptors will be different.
- *
- * Be sure to examine and test the results of autoconfiguration on your
- * hardware.  This code may not make the best choices about how to use the
- * USB controller, and it can't know all the restrictions that may apply.
- * Some combinations of driver and hardware won't be able to autoconfigure.
- *
- * On success, this returns an un-claimed usb_ep, and modifies the endpoint
- * descriptor bEndpointAddress.  For bulk endpoints, the wMaxPacket value
- * is initialized as if the endpoint were used at full speed.  To prevent
- * the endpoint from being returned by a later autoconfig call, claim it
- * by assigning ep->driver_data to some non-null value.

- * following fields:
- *
- *	nluns		Number of LUNs function have (anywhere from 1
- *				to FSG_MAX_LUNS which is 8).
- *	luns		An array of LUN configuration values.  This
- *				should be filled for each LUN that
- *				function will include (ie. for "nluns"
- *				LUNs).  Each element of the array has
- *				the following fields:
- *	->filename	The path to the backing file for the LUN.
- *				Required if LUN is not marked as
- *				removable.
- *	->ro		Flag specifying access to the LUN shall be
- *				read-only.  This is implied if CD-ROM
- *				emulation is enabled as well as when
- *				it was impossible to open "filename"
- *				in R/W mode.
- *	->removable	Flag specifying that LUN shall be indicated as
- *				being removable.
- *	->cdrom		Flag specifying that LUN shall be reported as
- *				being a CD-ROM.
- *	->nofua		Flag specifying that FUA flag in SCSI WRITE(10,12)
- *				commands for this LUN shall be ignored.
- *
- *	vendor_name
- *	product_name
- *	release		Information used as a reply to INQUIRY
- *				request.  To use default set to NULL,
- *				NULL, 0xffff respectively.  The first
- *				field should be 8 and the second 16
- *				characters or less.
- *
- *	can_stall	Set to permit function to halt bulk endpoints.
- *				Disabled on some USB devices known not
- *				to work correctly.  You should set it
- *				to true.
- *
- * If "removable" is not set for a LUN then a backing file must be
- * specified.  If it is set, then NULL filename means the LUN's medium
- * is not loaded (an empty string as "filename" in the fsg_config
- * structure causes error).  The CD-ROM emulation includes a single
- * data track and no audio tracks; hence there need be only one
- * backing file per LUN.
- *
- * This function is heavily based on "File-backed Storage Gadget" by

- * Brownell.  The driver's SCSI command interface was based on the

- * document from X3T9.2 Project 375D, Revision 10L, 7-SEP-93,
- * available at <http://www.t10.org/ftp/t10/drafts/s2/s2-r10l.pdf>.
- * The single exception is opcode 0x23 (READ FORMAT CAPACITIES), which
- * was based on the "Universal Serial Bus Mass Storage Class UFI
- * Command Specification" document, Revision 1.0, December 14, 1998,
- * available at
- * <http://www.usb.org/developers/devclass_docs/usbmass-ufi10.pdf>.

-
-/*
- *				Driver Design
- *
- * The MSF is fairly straightforward.  There is a main kernel
- * thread that handles most of the work.  Interrupt routines field
- * callbacks from the controller driver: bulk- and interrupt-request
- * completion notifications, endpoint-0 events, and disconnect events.
- * Completion events are passed to the main thread by wakeup calls.  Many
- * ep0 requests are handled at interrupt time, but SetInterface,
- * SetConfiguration, and device reset requests are forwarded to the
- * thread in the form of "exceptions" using SIGUSR1 signals (since they
- * should interrupt any ongoing file I/O operations).
- *
- * The thread's main routine implements the standard command/data/status
- * parts of a SCSI interaction.  It and its subroutines are full of tests
- * for pending signals/exceptions -- all this polling is necessary since
- * the kernel has no setjmp/longjmp equivalents.  (Maybe this is an
- * indication that the driver really wants to be running in userspace.)
- * An important point is that so long as the thread is alive it keeps an
- * open reference to the backing file.  This will prevent unmounting
- * the backing file's underlying filesystem and could cause problems
- * during system shutdown, for example.  To prevent such problems, the
- * thread catches INT, TERM, and KILL signals and converts them into
- * an EXIT exception.
- *
- * In normal operation the main thread is started during the gadget's
- * fsg_bind() callback and stopped during fsg_unbind().  But it can
- * also exit when it receives a signal, and there's no point leaving
- * the gadget running when the thread is dead.  As of this moment, MSF
- * provides no way to deregister the gadget when thread dies -- maybe
- * a callback functions is needed.
- *
- * To provide maximum throughput, the driver uses a circular pipeline of
- * buffer heads (struct fsg_buffhd).  In principle the pipeline can be
- * arbitrarily long; in practice the benefits don't justify having more
- * than 2 stages (i.e., double buffering).  But it helps to think of the
- * pipeline as being a long one.  Each buffer head contains a bulk-in and
- * a bulk-out request pointer (since the buffer can be used for both
- * output and input -- directions always are given from the host's
- * point of view) as well as a pointer to the buffer and various state
- * variables.
- *
- * Use of the pipeline follows a simple protocol.  There is a variable
- * (fsg->next_buffhd_to_fill) that points to the next buffer head to use.
- * At any time that buffer head may still be in use from an earlier
- * request, so each buffer head has a state variable indicating whether
- * it is EMPTY, FULL, or BUSY.  Typical use involves waiting for the
- * buffer head to be EMPTY, filling the buffer either by file I/O or by
- * USB I/O (during which the buffer head is BUSY), and marking the buffer
- * head FULL when the I/O is complete.  Then the buffer will be emptied
- * (again possibly by USB I/O, during which it is marked BUSY) and
- * finally marked EMPTY again (possibly by a completion routine).
- *
- * A module parameter tells the driver to avoid stalling the bulk
- * endpoints wherever the transport specification allows.  This is
- * necessary for some UDCs like the SuperH, which cannot reliably clear a
- * halt on a bulk endpoint.  However, under certain circumstances the
- * Bulk-only specification requires a stall.  In such cases the driver
- * will halt the endpoint and set a flag indicating that it should clear
- * the halt in software during the next device reset.  Hopefully this
- * will permit everything to work correctly.  Furthermore, although the
- * specification allows the bulk-out endpoint to halt when the host sends
- * too much data, implementing this would cause an unavoidable race.
- * The driver will always use the "no-stall" approach for OUT transfers.
- *
- * One subtle point concerns sending status-stage responses for ep0
- * requests.  Some of these requests, such as device reset, can involve
- * interrupting an ongoing file I/O operation, which might take an
- * arbitrarily long time.  During that delay the host might give up on
- * the original ep0 request and issue a new one.  When that happens the
- * driver should not notify the host about completion of the original
- * request, as the host will no longer be waiting for it.  So the driver
- * assigns to each ep0 request a unique tag, and it keeps track of the
- * tag value of the request associated with a long-running exception
- * (device-reset, interface-change, or configuration-change).  When the
- * exception handler is finished, the status-stage response is submitted
- * only if the current ep0 request tag is equal to the exception request
- * tag.  Thus only the most recently received ep0 request will get a
- * status-stage response.
- *
- * Warning: This driver source file is too long.  It ought to be split up
- * into a header file plus about 3 separate .c files, to handle the details
- * of the Gadget, USB Mass Storage, and SCSI protocols.

-/*
- * This function is an RNDIS Ethernet port -- a Microsoft protocol that's
- * been promoted instead of the standard CDC Ethernet.  The published RNDIS
- * spec is ambiguous, incomplete, and needlessly complex.  Variants such as
- * ActiveSync have even worse status in terms of specification.
- *
- * In short:  it's a protocol controlled by (and for) Microsoft, not for an
- * Open ecosystem or markets.  Linux supports it *only* because Microsoft
- * doesn't support the CDC Ethernet standard.
- *
- * The RNDIS data transfer model is complex, with multiple Ethernet packets
- * per USB message, and out of band data.  The control model is built around
- * what's essentially an "RNDIS RPC" protocol.  It's all wrapped in a CDC ACM
- * (modem, not Ethernet) veneer, with those ACM descriptors being entirely
- * useless (they're ignored).  RNDIS expects to be the only function in its
- * configuration, so it's no real help if you need composite devices; and
- * it expects to be the first configuration too.
- *
- * There is a single technical advantage of RNDIS over CDC Ethernet, if you
- * discount the fluff that its RPC can be made to deliver: it doesn't need
- * a NOP altsetting for the data interface.  That lets it work on some of the
- * "so smart it's stupid" hardware which takes over configuration changes
- * from the software, and adds restrictions like "no altsettings".
- *
- * Unfortunately MSFT's RNDIS drivers are buggy.  They hang or oops, and
- * have all sorts of contrary-to-specification oddities that can prevent
- * them from working sanely.  Since bugfixes (or accurate specs, letting
- * Linux work around those bugs) are unlikely to ever come from MSFT, you
- * may want to avoid using RNDIS on purely operational grounds.
- *
- * Omissions from the RNDIS 1.0 specification include:
- *
- *   - Power management ... references data that's scattered around lots
- *     of other documentation, which is incorrect/incomplete there too.
- *
- *   - There are various undocumented protocol requirements, like the need
- *     to send garbage in some control-OUT messages.
- *
- *   - MS-Windows drivers sometimes emit undocumented requests.

- * This component encapsulates the Ethernet link glue needed to provide
- * one (!) network link through the USB gadget stack, normally "usb0".
- *
- * The control and data models are handled by the function driver which
- * connects to this code; such as CDC Ethernet (ECM or EEM),
- * "CDC Subset", or RNDIS.  That includes all descriptor and endpoint
- * management.
- *
- * Link level addressing is handled by this component using module
- * parameters; if no such parameters are provided, random link level
- * addresses are used.  Each end of the link uses one address.  The
- * host end address is exported in various ways, and is often recorded
- * in configuration databases.
- *
- * The driver which assembles each configuration using such a link is
- * responsible for ensuring that each configuration includes at most one
- * instance of is network link.  (The network layer provides ways for
- * this single "physical" link to be used by multiple virtual links.)

- * This component encapsulates the TTY layer glue needed to provide basic

- *
- * After initialization (gserial_setup), these TTY port devices stay
- * available until they are removed (gserial_cleanup).  Each one may be
- * connected to a USB function (gserial_connect), or disconnected (with
- * gserial_disconnect) when the USB host issues a config change event.
- * Data can only flow when the port is connected to the host.
- *
- * A given TTY port can be made available in multiple configurations.
- * For example, each one might expose a ttyGS0 node which provides a
- * login application.  In one case that might use CDC ACM interface 0,
- * while another configuration might use interface 3 for that.  The
- * work to handle that (including descriptor management) is not part
- * of this component.
- *
- * Configurations may expose more than one TTY port.  For example, if
- * ttyGS0 provides login service, then ttyGS1 might provide dialer access
- * for a telephone or fax link.  And ttyGS2 might be something that just
- * needs a simple byte stream interface for some messaging protocol that
