>Description:
my hpcmips machine fail to load kernel module /usr/lkm/pf.o.
it claims that there's undefined symbols 'bswap64' in kernel.

bswap64 is included in libkernel but
all mips arch seems always build libkernel as *.a, not *.o.
so it may not linked to kernel.


>How-To-Repeat:
# modload /usr/lkm/pf.o
/usr/lkm/pf.o(.text+0x5640): In function `pf_insert_state':
: undefined reference to `bswap64'
/usr/lkm/pf.o(.text+0x5644): In function `pf_insert_state':
: undefined reference to `bswap64'
/usr/lkm/pf.o(.text+0x56fc): In function `pf_insert_state':
: undefined reference to `bswap64'
/usr/lkm/pf.o(.text+0x5700): In function `pf_insert_state':
: undefined reference to `bswap64'
modload: can't prelink `/usr/lkm/pf.o' creating `/usr/lkm/pf'
#

$ nm /usr/lkm/pf.o | grep bswap64
         U bswap64

$ nm /netbsd | grep bswap
802ba520 T bswap16
802bb030 T bswap32
