>Fix:

	No idea. 

	The m{,ac}68k MD code changes that came with said
	malloc/kvm change are minimal (typedef changes in
	m68k/m68k/pmap_motorola.c and mac68k/mac68k/pmap_bootstrap.c,
	AFAICS), so the problems are rooted either in MI code, or in
	missing additions to MD code. Since the author of the changes
	has provided little documentation, I wouldn't know where to
	start.

 This means:
 - m68k pmap_init() calls uvm_km_alloc() (even before kmem changes)
 - it seems now uvm_km_alloc() depends on structures which are initialized
   in pmap_init() and uvm_km_alloc() is called before that initialization

 Previously it worked (for more than a decade), but I'm not sure if
 it was a vaild op or not.

    I was/is a valid operation.  The m68k ports intialize the mmu tables 
 with enough space so memory can be allocated prior to the pmap 
 intialization.  What's happening now is that the kmem changes will 
 allocation substantially more memory before pmap_init() is called, and the 
 initial mmu setup is no longer sufficient.  On my 128MB amiga, the 8 
 kernel PT pages was not sufficient, but increasing that to 12 was.  The 
 kmem changes allocates space base on the physical memory size, and Michael 
 van Elst had some interesting allocations with his 2GB system.

    I suspect that most (or all) m68k ports are going to need to increase 
 the intitial kernel PT page allocations during setup.

 Log Message:
 The recent kmem changes allocate a large kernel address space before
 pmap_init() is called, and the initial kernel PT pages aren't enough
 for the allocations pmap_init().  This fails because pmap_kenter_pa()
 tries to allocate a new kernel PT page and traps because the pmap has
 not been initialized.  When computing the number if initial kernel PT
 pages, include enough to allow kmem to map the physical memory.  This
 should fix PR/45915.  OK by releng@.  One mac68k system has been verified
 to boot.  Volunteers to test the others welcome.  Amigas with at least
 up to 128MB of memory were OK, but larger memory will need some adjusting.

 After this and the following changes
 http://mail-index.netbsd.org/source-changes/2012/02/10/msg031644.html
 http://mail-index.netbsd.org/source-changes/2012/02/10/msg031645.html
 now HP362 (68030/16MB), HP382 (68040/24MB), and NWS-1750(68030/16MB)
 work fine.

 Note sun3/80 (which has differnt pmap) seems to have different issue.
 (random stalls in m68k_compat_13_sigreturn13_stub()
  but not related to this PR).

 mac68k: A Quadra 650 with 136 MB RAM boots fine now.

Subject: PR/45915 CVS commit: [netbsd-6] src/sys/arch
Date: Mon, 27 Feb 2012 20:17:19 +0000

 Module Name:	src
 Committed By:	riz
 Date:		Mon Feb 27 20:17:19 UTC 2012

 Modified Files:
 	src/sys/arch/atari/atari [netbsd-6]: atari_init.c
 	src/sys/arch/x68k/x68k [netbsd-6]: pmap_bootstrap.c

 Log Message:
 Pull up following revision(s) (requested by tsutsui in ticket #55):
 	sys/arch/x68k/x68k/pmap_bootstrap.c: revision 1.59
 	sys/arch/atari/atari/atari_init.c: revision 1.99
 Use actual physmem size for allocation of bootstrap extra PT pages
 to avoid wasting pages on low memory machines.
 Improves atari specific part of PR/45915, tested on TT030.
 Reserve more bootstrap kernel PT pages if options EXTENDED_MEMORY is defined
 for VA allocation in the extended memory probe function and possible 128MB
 memory on 060turbo, as worksaround for x68k specific part of PR/45915.
 Fixes GENERIC kernel panic on X68030 even without extended memory.
 XXX: we should rather have proper probe function before pmap_bootstrap()
 Tested on 060turbo with 128MB SIMM by Y.Sugahara, and also
 tested on XM6i with 68030 and custom 128MB memory settings by isaki@.
 Should be pulled up to netbsd-6.

Responsible-Changed-From-To: tsutsui->port-m68k-maintainer
Responsible-Changed-By: tsutsui@NetBSD.org
Responsible-Changed-When: Sun, 04 Mar 2012 14:50:10 +0900
Responsible-Changed-Why:
This panic message is m68k pmap specific and some ports might still have
the issue. At least mvme68k updates physmem after bootstrap PT page allocation.
