2011-03-23	Normalize sentinel. Use _MACHINE__H_ and _<ARCH>__H_ properly and consitently.	Paul Irofti
	Discussed and okay drahn@. Okay deraadt@.
2010-12-26	Kill pmap_phys_address(), and force every driver's mmap() routine to return	Miod Vallat
	a physical address [more precisely, something suitable to pass to pmap_enter()'sphysical address argument]. This allows MI drivers to implement mmap() routines without having to know about the pmap_phys_address() implementation and #ifdef obfuscation.
2010-12-06	Change the signature of PMAP_PREFER from void PMAP_PREFER(..., vaddr_t *) to	Miod Vallat
	vaddr_t PMAP_PREFER(..., vaddr_t). This allows better compiler optimization when the function is inlined, and avoids accessing memory on architectures when we can pass function arguments in registers.
2010-11-18	Declare pmap_proc_iflush() in <uvm/uvm_pmap.h> unless <machine/pmap.h>	Miod Vallat
	provides an inline version of it.
2007-09-10	Introduce a md pmap hook, pmap_remove_holes(), which is supposed to mark	Miod Vallat
	the holes a MMU may have from a given vm_map. This will be automagically invoked for newly created vmspaces. On platforms with MMU holes (e.g. sun4, sun4c and vax), this prevents mmap(2) hints which would end up being in the hole to be accepted as valid, causing unexpected signals when the process tries to access the hole (since pmap can not fill the hole anyway). Unfortunately, the logic mmap() uses to pick a valid address for anonymous mappings needs work, as it will only try to find an address higher than the hint, which causes all mmap() with a hint in the hole to fail on vax. This will be improved later.
2005-04-19	As a late birthday present, a preliminary port to the Solbourne IDT systems	Miod Vallat
	(S3000, S4000 and S4000DX). Currently limited to diskless and serial console, and userland has issues. Things will get better in the near future.
