 I have investigated the code for MREMAP_FIXED in
sparc_mremap in arch/sparc/kernel/sys_sparc.c, for sys64_mremap
in arch/sparc64/kernel/sys_sparc.c and 
for sys32_mremap in arch/sparc64/kernel/sys_sparc32.c
and there are similar conditional range checks ->
attaching the patches against 2.6.25.3.

Kind regards
Jan iankko Lieskovsky
