                     54:        export addresses very strictly. If you upgrade your kernel,
                     55:        make sure you also upgrade mountd, because if your export

                     57:        a.b.c or a.b or a), they will get rejected by the new kernel.

                     61:        fsck binaries, they will signal a fatal superblock mismatch

                     63:        fields (even ones that aren't useful).  If possible, upgrade
                     64:        your fsck_ffs binary before using a new kernel.
                     65:        None of this signals actual filesystem damage.

                     90:        This only affects people building with UNPRIVED.

                    127:        (and their companions crtbeginS.o and crtendS.o) were

                    141:        corrected.
                    142:
                    143:        NetBSD ARM ELF uses the soft-VFP floating point model by
                    144:        default.  However, the assembler lacked support for marking
                    145:        objects as using the VFP floating point format, and the
1.79      wiz       146:        compiler was not properly passing the flag indicating "soft-VFP"
1.75      thorpej   147:        to the assembler.
                    148:
                    149:        Unfortunately, this means that the linker will now consider
                    150:        old (i.e. not marked "softvfp") NetBSD ARM ELF objects to be
                    151:        incompatible with new (properly marked) objects.
                    152:
                    153:        The problem will only manifest itself if you attempt to compile
                    154:        a new program using the fixed toolchain, and link that program
                    155:        against old libraries which do not have the proper "softvfp"
                    156:        markings.  ALL OF YOUR EXISTING BINARIES AND SHARED LIBRARIES

                    158:
                    159:        The only work-around for the problem is to recompile all of
                    160:        the libraries on the system.  The easiest way to do this for
1.79      wiz       161:        system libraries is to install a binary snapshot; they are
