+/* The purpose of this file is to export a small set of atomic-related
+ * functions from the C library, to ensure binary ABI compatibility for
+ * the NDK.
+ *
+ * These functions were initially exposed by the NDK through <sys/atomics.h>,
+ * which was unfortunate because their implementation didn't provide any
+ * memory barriers at all.
+ *
+ * This wasn't a problem for the platform code that used them, because it
+ * used explicit barrier instructions around them. On the other hand, it means
+ * that any NDK-generated machine code that linked against them would not
+ * perform correctly when running on multi-core devices.
+ *
+ * To fix this, the platform code was first modified to not use any of these
+ * functions (everything is now inlined through assembly statements, see
+ * libc/private/bionic_arm_inline.h and the headers it includes.
+ *
+ * The functions here are thus only for the benefit of NDK applications,
+ * and now includes full memory barriers to prevent any random memory ordering
+ * issue from cropping.
+ *
+ * Note that we also provide an updated <sys/atomics.h> header that defines
+ * always_inlined versions of the functions that use the GCC builtin
+ * intrinsics to perform the same thing.
+ *
+ * NOTE: There is no need for a similar file for non-ARM platforms.

+ * ===========================================================================
+ *      Deadlock prediction
+ * ===========================================================================
+ */
+/*
+The idea is to predict the possibility of deadlock by recording the order
+in which locks are acquired.  If we see an attempt to acquire a lock
+out of order, we can identify the locks and offending code.
+
+To make this work, we need to keep track of the locks held by each thread,
+and create history trees for each lock.  When a thread tries to acquire
+a new lock, we walk through the "history children" of the lock, looking
+for a match with locks the thread already holds.  If we find a match,
+it means the thread has made a request that could result in a deadlock.
+
+To support recursive locks, we always allow re-locking a currently-held
+lock, and maintain a recursion depth count.
+
+An ASCII-art example, where letters represent locks:
+
+        A
+       /|\
+      / | \
+     B  |  D
+      \ |
+       \|
+        C
+
+The above is the tree we'd have after handling lock synchronization
+sequences "ABC", "AC", "AD".  A has three children, {B, C, D}.  C is also
+a child of B.  (The lines represent pointers between parent and child.
+Every node can have multiple parents and multiple children.)
+
+If we hold AC, and want to lock B, we recursively search through B's
+children to see if A or C appears.  It does, so we reject the attempt.
+(A straightforward way to implement it: add a link from C to B, then
+determine whether the graph starting at B contains a cycle.)
+
+If we hold AC and want to lock D, we would succeed, creating a new link
+from C to D.
+
+Updates to MutexInfo structs are only allowed for the thread that holds
+the lock, so we actually do most of our deadlock prediction work after
+the lock has been acquired.

+# This file does the bulk of the work to auto post-process kernel headers
+# provided by the device, board, and/or product.
+#
+# The build system exposes several variables for where to find the kernel
+# headers:
+#   TARGET_DEVICE_KERNEL_HEADERS is automatically created for the current
+#       device being built. It is set as $(TARGET_DEVICE_DIR)/kernel-headers,
+#       e.g. device/samsung/tuna/kernel-headers. This directory is not
+#       explicitly set by anyone, the build system always adds this subdir.
+#
+#   TARGET_BOARD_KERNEL_HEADERS is specified by the BoardConfig.mk file
+#       to allow other directories to be included. This is useful if there's
+#       some common place where a few headers are being kept for a group
+#       of devices. For example, device/<vendor>/common/kernel-headers could
+#       contain some headers for several of <vendor>'s devices.
+#
+#   TARGET_PRODUCT_KERNEL_HEADERS is generated by the product inheritance
+#       graph. This allows architecture products to provide headers for the
+#       devices using that architecture. For example,
+#       hardware/ti/omap4xxx/omap4.mk will specify
+#       PRODUCT_VENDOR_KERNEL_HEADERS variable that specify where the omap4
+#       specific headers are, e.g. hardware/ti/omap4xxx/kernel-headers.
+#       The build system then combines all the values specified by all the
+#       PRODUCT_VENDOR_KERNEL_HEADERS directives in the product inheritance
+#       tree and then exports a TARGET_PRODUCT_KERNEL_HEADERS variable.
+#
+# The directories specified in these three variables are scanned for header
+# files (files with .h suffix), processed with the clean_header.py script,
+# and dumped under TARGET_OUT_KERNEL_HEADERS
+# (typically $OUT/obj/kernel-headers). This subdirectory is then
+# automatically added to the include path.
+#
+# The files to be generated are added as a dependency to the
+# all_copied_headers rule to make sure that they are generated before
+# any C/C++ file that may need them.

+ * in a bracket expression matching list, e.g. "[.abc]" does NOT match a leading

+ * a valid bracket expression is treated as an ordinary character; 4. a differing
+ * number of consecutive slashes within pattern and string will NOT match;
+ * 5. a trailing '\' in FNM_ESCAPE mode is treated as an ordinary '\' character.

+ * Bracket expansion defined in section 9.3.5, "RE Bracket Expression",

+ *
+ * Supports BSD extensions FNM_LEADING_DIR to match pattern to the end of one

+ *
+ * NOTE: Only POSIX/C single byte locales are correctly supported at this time.

+ *
+ * XXX comments below indicate porting required for multi-byte character sets
+ * and non-POSIX locale collation orders; requires mbr* APIs to track shift
+ * state of pattern and string (rewinding pattern and string repeatedly).
+ *
+ * Certain parts of the code assume 0x00-0x3F are unique with any MBCS (e.g.
+ * UTF-8, SHIFT-JIS, etc).  Any implementation allowing '\' as an alternate
+ * path delimiter must be aware that 0x5C is NOT unique within SHIFT-JIS.
