     If the new code is substantial, addition of subsystem-specific fault
     injection might be appropriate.
+
+22: Newly-added code has been compiled with `gcc -W'.  This will generate
+    lots of noise, but is good for finding bugs like "warning: comparison
+    between signed and unsigned".

-The Linux version of the 9p server is now maintained under the npfs project
-on sourceforge (http://sourceforge.net/projects/npfs).
+Our current recommendation is to use Inferno (http://www.vitanuova.com/inferno)
+as the 9p server.  You can start a 9p server under Inferno by issuing the
+following command:
+   ; styxlisten -A tcp!*!564 export '#U*'
+
+The -A specifies an unauthenticated export.  The 564 is the port # (you may
+have to choose a higher port number if running as a normal user).  The '#U*'
+specifies exporting the root of the Linux name space.  You may specify a
+subset of the namespace by extending the path: '#U*'/tmp would just export
+/tmp.  For more information, see the Inferno manual pages covering styxlisten
+and export.
+
+A Linux version of the 9p server is now maintained under the npfs project
+on sourceforge (http://sourceforge.net/projects/npfs).  There is also a
+more stable single-threaded version of the server (named spfs) available from
+the same CVS repository.
 
 There are user and developer mailing lists available through the v9fs project
 on sourceforge (http://sourceforge.net/projects/v9fs).

 Dump-capture kernel config options (Arch Dependent, ia64)
 ----------------------------------------------------------
-(To be filled)
+
+- No specific options are required to create a dump-capture kernel
+  for ia64, other than those specified in the arch idependent section
+  above. This means that it is possible to use the system kernel
+  as a dump-capture kernel if desired.
+
+  The crashkernel region can be automatically placed by the system
+  kernel at run time. This is done by specifying the base address as 0,
+  or omitting it all together.
+
+  crashkernel=256M@0
+  or
+  crashkernel=256M
+
+  If the start address is specified, note that the start address of the
+  kernel will be aligned to 64Mb, so if the start address is not then
+  any space below the alignment point will be wasted.
 
 
 Boot into System Kernel
···
    On x86 and x86_64, use "crashkernel=64M@16M".
 
    On ppc64, use "crashkernel=128M@32M".
+
+   On ia64, 256M@256M is a generous value that typically works.
+   The region may be automatically placed on ia64, see the
+   dump-capture kernel config option notes above.
 
 Load the Dump-capture Kernel

 will remove the key op pointed to by 'op_p' from the key 'key', if and only if
 it is currently registered in that slot. This is in case the slot has been
 overwritten since you registered it.
···
 The Magic SysRQ system works by registering key operations against a key op
 lookup table, which is defined in 'drivers/char/sysrq.c'. This key table has
 a number of operations registered into it at compile time, but is mutable,
-and 4 functions are exported for interface to it: __sysrq_lock_table,
-__sysrq_unlock_table, __sysrq_get_key_op, and __sysrq_put_key_op. The
-functions __sysrq_swap_key_ops and __sysrq_swap_key_ops_nolock are defined
-in the header itself, and the REGISTER and UNREGISTER macros are built from
-these. More complex (and dangerous!) manipulations of the table are possible
-using these functions, but you must be careful to always lock the table before
-you read or write from it, and to unlock it again when you are done. (And of
-course, to never ever leave an invalid pointer in the table). Null pointers in
-the table are always safe :)
+and 2 functions are exported for interface to it:
+	register_sysrq_key and unregister_sysrq_key.
+Of course, never ever leave an invalid pointer in the table. I.e., when
+your module that called register_sysrq_key() exits, it must call
+unregister_sysrq_key() to clean up the sysrq key table entry that it used.
+Null pointers in the table are always safe. :)
 
 If for some reason you feel the need to call the handle_sysrq function from
 within a function called by handle_sysrq, you must be aware that you are in
