+
+       * : Tag spl-0.4.4
+
+       * : Added SLES10 support.  This includes all compatibility
+       changes to support 2.6.16 based kernels and the required
+       build system improvements.
+
+       * : Build System changes for SLES10:
+       - Exclude -obj when detecting installed kernel source.
+       - Detect -obj directory for out of tree kernel builds.
+       - Allow kernel build system to set CC to ensure -m64 is set properly.
+         This is an issue on 64-bit SLES systems which by default always
+         build 32-bit binaries (unlike RHEL/Fedora which default to 64-bit)
+
+       * : Configure Checks added for SLES10:
+       - div64_64() renamed to div64_u64() as of 2.6.26.
+       - global_page_state() fuction was introduced in 2.6.18 kernels.
+         The earlier 2.6.16 based SLES10 must not try and use it,
+         thankfully get_zone_counts() is still available.
+       - monotonic_clock() is unavailable __gethrtime() must perform the
+         HZ division as an 'unsigned long long' because the SPL only
+         implements __udivdi3(), and not __divdi3() for 'long long'
+         division on 32-bit arches.
+       - mutex_lock_nested() was introduced as part of the mutex
+         validator in 2.6.18, when it is unavailable it is safe to
+         fallback to using a plain mutex_lock().
+       - SLES specific API change to vfs_unlink() and vfs_rename() which
+         added a 'struct vfsmount *' argument.  This was for something
+         called the linux-security-module, but it appears that it was
+         never adopted upstream.
+       - spl_device_create() correctly mapped to class_device_create()
+         for 2.6.13 to 2.6.17 based kernels, this is the preferred API.
+       - Prior to 2.6.17 there were no *_pgdat helper functions in 
+         mm/mmzone.c.  Instead for_each_zone() operated directly on
+         pgdat_list which may or may not have been exported depending on
+         how your kernel was compiled.  A configure check was added to
+         determine if you have the helpers or not, and if the needed
+         symbols are exported.  If they are not exported then they are
+         dynamically aquired at runtime by kallsyms_lookup_name().
+
+       * : Packaging changes for SLES10
+       - Properly honor --prefix in build system and rpm spec file.
+       - Add '--define require_kdir' to spec file to support building
+         rpms against kernel sources installed in non-default locations.
+       - Add '--define require_kobj' to spec file to support building
+         rpms against kernel object installed in non-default locations.
+       - Stop suppressing errors in autogen.sh script.
+       - Improved logic to detect missing kernel objects when they are
+         not located with the source.  This is the common case for SLES
+         as well as in-tree chaos kernel builds and is done to simply
+         support for multiple arches.
+       - Moved spl-devel build products to /usr/src/spl-<version>, a
+         spl symlink is created to reference the last installed version.
+       - Allow checking for exported symbols in both Module.symvers
+         and Module.symvers.  My stock SLES kernel ships an objects
+         directory with Module.symvers, yet produces a Module.symvers
+         in the local build directory.
+
+       * : Added powerpc64 support.
+       - Enable builds for powerpc64 ISA type.
+       - Add DIV_ROUND_UP and roundup macros if unavailable.
+       - Cast 64-bit values for %lld format string to (long long) to
+         quiet compile warning.
+
+       * module/splat/splat-ctl.c: Proper ioctl() 32/64-bit binary
+         compatibility.  We need to ensure the ioctl data itself is always
+         packed the same for 32/64-bit binaries.  Additionally, the correct
+         thing to do is encode this size in bytes as part of the command
+         using _IOC_SIZE().
+
+       * modules/spl/spl-kmem.c: Fixed a long standing bug in the debug
+         tracing.  The tcd_for_each() macro expected a NULL to terminate
+         the trace_data[i] array but this was only ever true due to luck.
+         All trace_data[] iterators are now properly capped by TCD_TYPE_MAX.
+
+       * modules/spl/spl-kmem.c: To simplify debugging all symbols aquired
+         dynamically using spl_kallsyms_lookup_name() are initially poisoned
+         with SYMBOL_POISON.
