takemura cdabc2eb91 Hpcmips needs completely FPU instruction free user land.

after a change to the one, we can just copy it over to update the other
without creating ... problems. By Chris G.  Demetriou.

mycroft 0ae41d0984 Use the C version of ldexp(). The assembler version was broken in several

thorpej 30dca7f7db Add __msgctl13(), __semctl13(), and __shmctl13() (symbols are __RENAME()'d
in their respective header files).  Add PSEUDO stubs for the old versions
of these system calls.

Note that __semctl13() doesn't require the extra stub that the old
semctl()/__semctl() did, as the SUSv2 version takes variable arguments,
and thus does not require the extra indirection.

of a commit message kernel calls are needed.) And much kernel Magick is
required before these do anything, but this way programs compiled under
