+
+		Under that directory are a number of files:
+
+			partition_id
+			coherence_id
+
+		The partition_id entry contains the partition id.
+		SGI UV systems can be partitioned into multiple physical
+		machines, which each partition running a unique copy
+		of the operating system.  Each partition will have a unique
+		partition id.  To display the partition id, use the command:
+
+			cat /sys/firmware/sgi_uv/partition_id
+
+		The coherence_id entry contains the coherence id.
+		A partitioned SGI UV system can have one or more coherence
+		domain.  The coherence id indicates which coherence domain
+		this partition is in.  To display the coherence id, use the
+		command:
+
+			cat /sys/firmware/sgi_uv/coherence_id

Subject: update Documentation/filesystems/Locking for 2.6.27 changes

In the 2.6.27 circle ->fasync lost the BKL, and the last remaining
->open variant that takes the BKL is also gone.  ->get_sb and ->kill_sb
didn't have BKL forever, so updated the entries while we're at that.

+  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.
