* sysdeps/unix/sysv/linux/mips/profil-counter: New. * sysdeps/unix/sysv/linux/mips/sigcontextinfo.h: Port to n32/n64. * sysdeps/unix/sysv/linux/mips/bits/sigcontext.h: New. * sysdeps/unix/sysv/linux/mips/sys/ucontext.h: Port to n32/n64. (mcontext_t): Make it match the 32-bit mips kernel in o32. * sysdeps/unix/sysv/linux/mips/sys/user.h: Bring in constants from the mips and mips64 headers. (struct user): Port to n32/n64.

ucontext_t in glibc mustn't have accessed anything beyond
uc_mcontext and, even then, taking a pointer to it, casting it to
sigcontext_t, and accessing it as such, which is what it has always
been, this can still be rectified. Fortunately, makecontext,
[gs]etcontext et all have never been implemented. */
