Modified Files:
src/sys/arch/alpha/alpha: vm_machdep.c
Log Message:
Nowadays we can create new kernel threads late after boot, so if we are
unable to find physically continous pages for their uarea, just allocate
them via uvm_km_alloc(), that is: make cpu_uarea_alloc() fail instead
of panic. cpu_uarea_free() already deals with this.
Should fix PR port-alpha/53077.
Discussed with maxv and mrg.
