+INFINIBAND MIDLAYER LOCKING
+
+  This guide is an attempt to make explicit the locking assumptions
+  made by the InfiniBand midlayer.  It describes the requirements on
+  both low-level drivers that sit below the midlayer and upper level
+  protocols that use the midlayer.
+
+Sleeping and interrupt context
+
+  With the following exceptions, a low-level driver implementation of
+  all of the methods in struct ib_device may sleep.  The exceptions
+  are any methods from the list:
+
+    create_ah
+    modify_ah
+    query_ah
+    destroy_ah
+    bind_mw
+    post_send
+    post_recv
+    poll_cq
+    req_notify_cq
+    map_phys_fmr
+
+  which may not sleep and must be callable from any context.
+
+  The corresponding functions exported to upper level protocol
+  consumers:
+
+    ib_create_ah
+    ib_modify_ah
+    ib_query_ah
+    ib_destroy_ah
+    ib_bind_mw
+    ib_post_send
+    ib_post_recv
+    ib_req_notify_cq
+    ib_map_phys_fmr
+
+  are therefore safe to call from any context.
+
+  In addition, the function
+
+    ib_dispatch_event
+
+  used by low-level drivers to dispatch asynchronous events through
+  the midlayer is also safe to call from any context.
+
+Reentrancy
+
+  All of the methods in struct ib_device exported by a low-level
+  driver must be fully reentrant.  The low-level driver is required to
+  perform all synchronization necessary to maintain consistency, even
+  if multiple function calls using the same object are run
+  simultaneously.
+
+  The IB midlayer does not perform any serialization of function calls.
+
+  Because low-level drivers are reentrant, upper level protocol
+  consumers are not required to perform any serialization.  However,
+  some serialization may be required to get sensible results.  For
+  example, a consumer may safely call ib_poll_cq() on multiple CPUs
+  simultaneously.  However, the ordering of the work completion
+  information between different calls of ib_poll_cq() is not defined.
+
+Callbacks
+
+  A low-level driver must not perform a callback directly from the
+  same callchain as an ib_device method call.  For example, it is not
+  allowed for a low-level driver to call a consumer's completion event
+  handler directly from its post_send method.  Instead, the low-level
+  driver should defer this callback by, for example, scheduling a
+  tasklet to perform the callback.
+
+  The low-level driver is responsible for ensuring that multiple
+  completion event handlers for the same CQ are not called
+  simultaneously.  The driver must guarantee that only one CQ event
+  handler for a given CQ is running at a time.  In other words, the
+  following situation is not allowed:
+
+        CPU1                                    CPU2
+
+  low-level driver ->
+    consumer CQ event callback:
+      /* ... */
+      ib_req_notify_cq(cq, ...);
+                                        low-level driver ->
+      /* ... */                           consumer CQ event callback:
+                                            /* ... */
+      return from CQ event handler
+
+  The context in which completion event and asynchronous event
+  callbacks run is not defined.  Depending on the low-level driver, it
+  may be process context, softirq context, or interrupt context.
+  Upper level protocol consumers may not sleep in a callback.
+
+Hot-plug
+
+  A low-level driver announces that a device is ready for use by
+  consumers when it calls ib_register_device(), all initialization
+  must be complete before this call.  The device must remain usable
+  until the driver's call to ib_unregister_device() has returned.
+
+  A low-level driver must call ib_register_device() and
+  ib_unregister_device() from process context.  It must not hold any
+  semaphores that could cause deadlock if a consumer calls back into
+  the driver across these calls.
+
+  An upper level protocol consumer may begin using an IB device as
+  soon as the add method of its struct ib_client is called for that
+  device.  A consumer must finish all cleanup and free all resources
+  relating to a device before returning from the remove method.
+
+  A consumer is permitted to sleep in its add and remove methods.

+Creation of the self-extracting compressed kernel image (vmlinuz)
+-----------------------------------------------------------------
+$Id: README,v 1.1 2003/08/21 09:37:03 johana Exp $
+
+This can be slightly confusing because it's a process with many steps.
+
+The kernel object built by the arch/etrax100/Makefile, vmlinux, is split
+by that makefile into text and data binary files, vmlinux.text and
+vmlinux.data.
+
+Those files together with a ROM filesystem can be catted together and
+burned into a flash or executed directly at the DRAM origin.
+
+They can also be catted together and compressed with gzip, which is what
+happens in this makefile. Together they make up piggy.img.
+
+The decompressor is built into the file decompress.o. It is turned into
+the binary file decompress.bin, which is catted together with piggy.img
+into the file vmlinuz. It can be executed in an arbitrary place in flash.
+
+Be careful - it assumes some things about free locations in DRAM. It
+assumes the DRAM starts at 0x40000000 and that it is at least 8 MB,
+so it puts its code at 0x40700000, and initial stack at 0x40800000.
