Marcel Moolenaar 11e0f8e16d Change the second (and last) argument of cpu_set_upcall(). Previously ... we were passing in a void* representing the PCB of the parent thread. Now we pass a pointer to the parent thread itself. The prime reason for this change is to allow cpu_set_upcall() to copy (parts of) the trapframe instead of having it done in MI code in each caller of cpu_set_upcall(). Copying the trapframe cannot always be done with a simply bcopy() or may not always be optimal that way. On ia64 specifically the trapframe contains information that is specific to an entry into the kernel and can only be used by the corresponding exit from the kernel. A trapframe copied verbatim from another frame is in most cases useless without some additional normalization. Note that this change removes the assignment to td->td_frame in some implementations of cpu_set_upcall(). The assignment is redundant. A previous call to cpu_thread_setup() already did the exact same assignment. An added benefit of removing the redundant assignment is that we can now change td_pcb without nasty side-effects. This change officially marks the ability on ia64 for 1:1 threading. Not tested on: amd64, powerpc Compile & boot tested on: alpha, sparc64 Functionally tested on: i386, ia64		2003-06-04 21:13:21 +00:00
