+Date:		July 2008
+KernelVersion:	2.6.27
+Contact:	David Brownell <dbrownell@users.sourceforge.net>
+Description:
+
+  As a Kconfig option, individual GPIO signals may be accessed from
+  userspace.  GPIOs are only made available to userspace by an explicit
+  "export" operation.  If a given GPIO is not claimed for use by
+  kernel code, it may be exported by userspace (and unexported later).
+  Kernel code may export it for complete or partial access.
+
+  GPIOs are identified as they are inside the kernel, using integers in
+  the range 0..INT_MAX.  See Documentation/gpio.txt for more information.
+
+    /sys/class/gpio
+	/export ... asks the kernel to export a GPIO to userspace
+	/unexport ... to return a GPIO to the kernel
+	/gpioN ... for each exported GPIO #N
+	    /value ... always readable, writes fail for input GPIOs
+	    /direction ... r/w as: in, out (default low); write: high, low
+	/gpiochipN ... for each gpiochip; #N is its first GPIO

+ * Variant clock event timer support for SMTC on MIPS 34K, 1004K
+ * or other MIPS MT cores.
+ *
+ * Notes on SMTC Support:
+ *
+ * SMTC has multiple microthread TCs pretending to be Linux CPUs.
+ * But there's only one Count/Compare pair per VPE, and Compare
+ * interrupts are taken opportunisitically by available TCs
+ * bound to the VPE with the Count register.  The new timer
+ * framework provides for global broadcasts, but we really
+ * want VPE-level multicasts for best behavior. So instead
+ * of invoking the high-level clock-event broadcast code,
+ * this version of SMTC support uses the historical SMTC
+ * multicast mechanisms "under the hood", appearing to the
+ * generic clock layer as if the interrupts are per-CPU.
+ *
+ * The approach taken here is to maintain a set of NR_CPUS
+ * virtual timers, and track which "CPU" needs to be alerted
+ * at each event.
+ *
+ * It's unlikely that we'll see a MIPS MT core with more than
+ * 2 VPEs, but we *know* that we won't need to handle more
+ * VPEs than we have "CPUs".  So NCPUs arrays of NCPUs elements
+ * is always going to be overkill, but always going to be enough.

+ * roughly once every four billion events, which at 1000 HZ means

- * Branch Trace Store (BTS) records store information about control
- * flow changes. They at least provide the following information:
- * - source linear address
- * - destination linear address
+ * We compute the base address for the first 8 fields based on:
+ * - the field size stored in the DS configuration
+ * - the relative field position
+ * - an offset giving the start of the respective region
  *
- * Netburst supported a predicated bit that had been dropped in later
- * architectures. We do not suppor it.
+ * This offset is further used to index various arrays holding
+ * information for BTS and PEBS at the respective index.
  *
- *
- * In order to abstract from the actual DS and BTS layout, we describe
- * the access to the relevant fields.
- * Thanks to Andi Kleen for proposing this design.
- *
- * The implementation, however, is not as general as it might seem. In
- * order to stay somewhat simple and efficient, we assume an
- * underlying unsigned type (mostly a pointer type) and we expect the
- * field to be at least as big as that type.
+ * On later 32bit processors, we only access the lower 32bit of the
+ * 64bit pointer fields. The upper halves will be zeroed out.

 	tristate "generic/default IDE chipset support"
 	depends on ALPHA || X86 || IA64 || M32R || MIPS
 	help
+	  This is the generic IDE driver.  This driver attaches to the
+	  fixed legacy ports (e.g. on PCs 0x1f0/0x170, 0x1e8/0x168 and
+	  so on).  Please note that if this driver is built into the
+	  kernel or loaded before other ATA (IDE or libata) drivers
+	  and the controller is located at legacy ports, this driver
+	  may grab those ports and thus can prevent the controller
+	  specific driver from attaching.
+
+	  Also, currently, IDE generic doesn't allow IRQ sharing
+	  meaning that the IRQs it grabs won't be available to other
+	  controllers sharing those IRQs which usually makes drivers
+	  for those controllers fail.  Generally, it's not a good idea
+	  to load IDE generic driver on modern systems.
+
 	  If unsure, say N.
