I just wanted to make sure that you're happy with the wording in this
paragraph:

+* When locally debugging programs on PowerPC BookE processors running
+  a Linux kernel version 2.6.34 or later GDB supports masked hardware
+  watchpoints, which specifiy a mask in addition to an address to watch.
+  The mask specifies that some bits of an address (the bits which are
+  reset in the mask) should be ignored when matching the address accessed
+  by the inferior against the watchpoint address.  See the "PowerPC Embedded"
+  section in the user manual for more details.

and also with the new "Changed commands" section that I added. The
changes in the manual are the same and don't need review.
