include/ucontext.h - remove trapframe and switch over to 'generic' description of machine state. Include version field to help with future modifications. Include floating point and altivec state, and hopefully align correctly powerpc/copyinout.c - fill out casuptr() sync primitive, required by kern_umtx.c powerpc/machdep.c - shifted proc0/thread0/pcpu setup to before cninit, since syscons -> make_dev -> devlock requires a valid curthread - implemented get_mcontext/set_mcontext - recast sendsig/sigreturn to use get/set_mcontext and new ucontext struct. floating point now saved - TODO: save/restore altivec state powerpc/vm_machdep.c - implemented cpu_thread_setup/cpu_set_upcall/cpu_set_upcall_kse - eliminated trailing whitespace Submitted by: Suleiman Souhlal <refugee@segfaulted.com>, ucontext by grehan
