+ADAM G. LITKE <agl@us.ibm.com> - 
+Libhugetlbfs ships a set of linker scripts which can be used to enable ELF
+segment remapping into huge pages.  These linker scripts 
+no longer work with the version of binutils shipped with SLES11.
+
+This has been a known problem.  Linker scripts are essentially tied to specific
+versions of binutils but libhugetlbfs only ships a single 
+set.  To avoid maintaining and shipping an ever-growing number of linker
+scripts, a new method of linking binaries for use with huge 
+pages was developed in libhugetlbfs-2.0.  Unfortunately, some customers will
+likely continue to use the old method of linking 
+binaries (with the shipped linker scripts) and will experience problems.  The
+solution to this problem is either to fix the linker scripts 
+for SLES11 by supplying a distro-specific patch, or strip out the deprecated
+linker scripts so they cannot be used at all.  I would prefer 
+to fix the linker scripts (if possible) to allow customers more time to switch
+to the new linking method.
+
+Fix for ppc32 BDT script
+
+The only linker script that is known to have problems is the script used to
+place text, data, and bss into huge pages on 32bit 
+PowerPC.  The attached patch fixes the issue by adding the 'SPECIAL' notation
+to the .plt and .got sections which is required for 
+correct functioning of the dynamic linker.
