-The SMBus Driver
-----------------
-
-The SMBus driver allows up to 4 SMBus devices to be configured in the
-system.  By default, the driver will register any SMBus interfaces it finds
-in the I2C address range of 0x20 to 0x4f on any adapter.  You can change this
-at module load time (for a module) with:
-
-  modprobe ipmi_smb.o
-        addr=<adapter1>,<i2caddr1>[,<adapter2>,<i2caddr2>[,...]]
-        dbg=<flags1>,<flags2>...
-        [defaultprobe=1] [dbg_probe=1]
-
-The addresses are specified in pairs, the first is the adapter ID and the
-second is the I2C address on that adapter.
-
-The debug flags are bit flags for each BMC found, they are:
-IPMI messages: 1, driver state: 2, timing: 4, I2C probe: 8
-
-Setting smb_defaultprobe to zero disabled the default probing of SMBus
-interfaces at address range 0x20 to 0x4f.  This means that only the
-BMCs specified on the smb_addr line will be detected.
-
-Setting smb_dbg_probe to 1 will enable debugging of the probing and
-detection process for BMCs on the SMBusses.
-
-Discovering the IPMI compliant BMC on the SMBus can cause devices
-on the I2C bus to fail. The SMBus driver writes a "Get Device ID" IPMI
-message as a block write to the I2C bus and waits for a response.
-This action can be detrimental to some I2C devices. It is highly recommended
-that the known I2c address be given to the SMBus driver in the smb_addr
-parameter. The default address range will not be used when a smb_addr
-parameter is provided.
-
-When compiled into the kernel, the addresses can be specified on the
-kernel command line as:
-
-  ipmb_smb.addr=<adapter1>,<i2caddr1>[,<adapter2>,<i2caddr2>[,...]]
-        ipmi_smb.dbg=<flags1>,<flags2>...
-        ipmi_smb.defaultprobe=0 ipmi_smb.dbg_probe=1
-
-These are the same options as on the module command line.
-
-Note that you might need some I2C changes if CONFIG_IPMI_PANIC_EVENT
-is enabled along with this, so the I2C driver knows to run to
-completion during sending a panic event.

- * Linux system call numbers.

- * it will would keep a branch out of our syscall entry path, at the
- * very least.  If we decide to change it later, we can ``just'' tweak
- * the LINUX_GATEWAY_ADDR define at the bottom and make __NR_Linux be
- * 1024 or something.  Oh, and recompile libc. =)
- *
- * 64-bit HPUX binaries get the syscall gateway address passed in a register

+ * Cary Coutant says that we should just use another syscall gateway
+ * page to avoid clashing with the HPUX space, and I think he's right:
+ * it will would keep a branch out of our syscall entry path, at the
+ * very least.  If we decide to change it later, we can ``just'' tweak
+ * the LINUX_GATEWAY_ADDR define at the bottom and make __NR_Linux be
+ * 1024 or something.  Oh, and recompile libc. =)
+ *
+ * 64-bit HPUX binaries get the syscall gateway address passed in a register
+ * from the kernel at startup, which seems a sane strategy.

+ * This file holds USB constants and structures that are needed for
+ * USB device APIs.  These are used by the USB device model, which is
+ * defined in chapter 9 of the USB 2.0 specification and in the
+ * Wireless USB 1.0 (spread around).  Linux has several APIs in C that
+ * need these:
+ *
+ * - the master/host side Linux-USB kernel driver API;
+ * - the "usbfs" user space API; and
+ * - the Linux "gadget" slave/device/peripheral side driver API.
+ *
+ * USB 2.0 adds an additional "On The Go" (OTG) mode, which lets systems
+ * act either as a USB master/host or as a USB slave/device.  That means
+ * the master and slave side APIs benefit from working well together.
+ *
+ * There's also "Wireless USB", using low power short range radios for
+ * peripheral interconnection but otherwise building on the USB framework.
+ *
+ * Note all descriptors are declared '__attribute__((packed))' so that:
+ *
+ * [a] they never get padded, either internally (USB spec writers
+ *     probably handled that) or externally;
+ *
+ * [b] so that accessing bigger-than-a-bytes fields will never
+ *     generate bus errors on any platform, even when the location of
+ *     its descriptor inside a bundle isn't "naturally aligned", and
+ *
+ * [c] for consistency, removing all doubt even when it appears to
+ *     someone that the two other points are non-issues for that
+ *     particular descriptor type.
