Subject: PR/53077 CVS commit: src/sys/arch/alpha/alpha
Date: Mon, 19 Mar 2018 10:31:57 +0000

 Module Name:	src
 Committed By:	martin
 Date:		Mon Mar 19 10:31:56 UTC 2018

 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.
