Subject: [PATCH 3/3] staging: android: Add some Kconfig help entries

This commit adds Kconfig entries for the following:

	1: ANDROID_BINDER_IPC
	2: ASHMEM (additional text)
	3: ANDROID_LOGGER

It also changes "Register" to "Registers" in
ANDROID_LOW_MEMORY_KILLER

Finally, all "help" instances are changed to "---help---",
as recommended by kconfig-language.txt in order to visually
aid developers.

 config ANDROID_BINDER_IPC
 	bool "Android Binder IPC Driver"

+	---help---
+	  Binder is used in Android for both communication between processes,
+	  and remote method invocation.
+
+	  This means one Android process can call a method/routine in another
+	  Android process, using Binder to identify, invoke and pass arguments
+	  between said processes.

+	---help---
 	  The ashmem subsystem is a new shared memory allocator, similar to
 	  POSIX SHM but with different behavior and sporting a simpler
 	  file-based API.
 
+	  It is, in theory, a good memory allocator for low-memory devices,
+	  because it can discard shared memory units when under memory pressure.

 config ANDROID_LOGGER
 	tristate "Android log driver"
 	default n
+	---help---
+	  This adds support for system-wide logging using four log buffers.
+
+	  These are:
+
+	      1: main
+	      2: events
+	      3: radio
+	      4: system
+
+	  Log reading and writing is performed via normal Linux reads and
+	  optimized writes. This optimization avoids logging having too
+	  much overhead in the system.
