Konstantin Belousov 89b57fcf01 Fix for the panic("vm_thread_new: kstack allocation failed") and ... silent NULL pointer dereference in the i386 and sparc64 pmap_pinit() when the kmem_alloc_nofault() failed to allocate address space. Both functions now return error instead of panicing or dereferencing NULL. As consequence, vmspace_exec() and vmspace_unshare() returns the errno int. struct vmspace arg was added to vm_forkproc() to avoid dealing with failed allocation when most of the fork1() job is already done. The kernel stack for the thread is now set up in the thread_alloc(), that itself may return NULL. Also, allocation of the first process thread is performed in the fork1() to properly deal with stack allocation failure. proc_linkup() is separated into proc_linkup() called from fork1(), and proc_linkup0(), that is used to set up the kernel process (was known as swapper).
