2005-01-04	SET_PC_REGS, arches tested between me and miod.	Marc Espie

2005-01-04	Better check for UPT filling; saves one more page for userland on most hp300...	Miod Vallat

2004-12-30	Do the address space checks only if option DEBUG - nobody has seen them	Miod Vallat
	triggered in BSD since a very, very long time, if ever.
2004-12-30	Rework pmap_bootstrap() computations of I/O maps. Makes the MD part of	Miod Vallat
	this much simpler. Also, make sure an userland process can fill its UPT as expected. No functional change.
2004-12-25	Use list and queue macros where applicable to make the code easier to read;	Miod Vallat
	no functional change.
2004-11-30	repair DEBUG kernels	Martin Reindl
	ok miod@
2004-11-28	MAXSLP is not really an MD-configurable define so move it to param.h; miod@ ↵	Michael Shalayeff
	testing
2004-11-27	In pmap_bootstrap(), replace PMAP_MD_RWZERO, which would leave the lowest	Miod Vallat
	page writeable, with PMAP_MD_RWLOW, which tells how many pages have to be left writeable on low addresses, since the mac rom needs more than one. This lets non-DDB mac68k kernels run. No change on non-mac68k platforms.
2004-10-16	Provide a dummp __swap64md() on MD_SWAP architectures; needed by nm(1) now.	Miod Vallat

2004-08-07	Need pmap_unuse_final() too; Martin Reindl.	Miod Vallat

2004-08-06	provide md USPACE_ALIGN zero on all but mips; deradat@ pefo@ ok	Michael Shalayeff

2004-07-22	Make the inline bzero() of the U area much more readable.	Miod Vallat
	As a bonus it generates smaller and faster code.
2004-07-02	Cope with SONPROC scheduler changes.	Miod Vallat

2004-05-20	Properly flush instruction cache for ptrace(PT_WRTIE_{DI}, ...) on powerpc	Mark Kettenis
	and m68k. ok drahn@, millert@
2004-04-19	remove the GATEWAY junk thingy; at the same time, select a new fat	Theo de Raadt
	cluster value that noone will really need to crank.
2004-04-12	Fix process_frame macro.	Mark Kettenis
	ok miod@
2004-02-19	When copyout() of the signal frame fails, sigexit() the process instead of	Miod Vallat
	doing this by an hand-delivered SIGILL.
2004-01-27	Only install the fpsp exception vectors if the cpu is a 68040.	Miod Vallat
	Thus, it becomes unnecessary to check for the cpu type in the exception handlers, saving a few cycles and a few bytes. Tested by various people on hp300, mac68k, mvme68k, 68040 and non-68040.
2004-01-15	instuction -> instruction	Miod Vallat

2004-01-09	spelling; jjy2+@pitt.edu	Theo de Raadt

2004-01-03	put an mi wrapper around stdarg.h/varargs.h. gcc3 moved stdarg/varargs macros	Marc Espie
	to built-ins, so eventually we will have one version of these files. Special adjustments for the kernel to cope: machine/stdarg.h -> sys/stdarg.h and machine/ansi.h needs to have a _BSD_VA_LIST_ for syslog* prototypes. okay millert@, drahn@, miod@.
2004-01-01	Inline pmap_copy() and pmap_phys_address().	Miod Vallat
	Also get rid of a spurious local initialization in pmap_remove_mapping().
2003-12-26	A simple compile-time micro-optimization in pmap_protect() for	Miod Vallat
	non-hp300 flavours.
2003-12-16	becuase	Theo de Raadt

2003-12-14	In pmap_testbit, always update the attribute flags for the pv list hander.	Miod Vallat
	Fixes a regression introduced in the conversion from physseg to VM_PAGE_MD.
2003-11-16	convert __attribute__((__packed__)) to __packed so that parsers unaware	Anil Madhavapeddy
	of gcc extensions have more of a chance. ok mcbride@, no objections from millert@, deraadt@
2003-11-07	"the the" -> "the"; rohee@	Miod Vallat

2003-11-02	pmap_remove_mapping() uses an unnecessary PHYS_TO_VM_PAGE call. Instead of	Miod Vallat
	simply removing it, slightly reorganize the code to remove a pg_to_pvh() call as well.
2003-10-13	More m68k pmap tweaks:	Miod Vallat
	- simplify pmap_protect() - simplify reference count managment by using 0 as a base instead of 1 (from NetBSD)
2003-10-09	A few 68060 bugfixes with side effects:	Miod Vallat
	- honor PRM_CFLUSH correctly for 0[46]0 in pmap_remove_mapping(). - be sure to flush caches in pmap_changebit for 060 too when necessary. - make this compile if option DEBUG is defined.
2003-10-09	More m68k common include files factorization.	Miod Vallat

2003-09-26	Typos: defintion -> definition, proccess -> process	Miod Vallat
	There are more occurences hiding in binutils, lynx and afs but I am too lazy to report them upstream at the moment.
2003-08-01	Nuke calls to uvm_useracc() and instead check copyin() and copyout() for	Miod Vallat
	failure, since the former is not reliable; requested by art@ long ago.
2003-06-12	final bits of obvious UCB term 3 removal	Theo de Raadt

2003-06-04	Delete UCB term 3. When there are other copyright owners, we affirm	Theo de Raadt
	that we can see no legal situation under which they could require that term to remain (ie. This is equivelant to us taking the old UCB file, removing term 3 as specified by UCB, then re-applying each diff afterwards from the various authors)
2003-06-03	terms 3 & 4 cleanup based on "terms" file	Theo de Raadt

2003-06-02	Remove the advertising clause in the UCB license which Berkeley	Todd C. Miller
	rescinded 22 July 1999. Proofed by myself and Theo.
2003-06-02	licence cleanup	Theo de Raadt

2003-05-31	Remove a bunch of obsolete definitions.	Miod Vallat

2003-03-03	Prefer pmap_kenter_pa() in pmap_map().	Miod Vallat

2003-03-01	- only declare and provide pmap_map() for mac68k, until it bites the dust.	Miod Vallat
	Other m68k-based arches do not need it. - do not wait to allocate struct pv_page. Either pmap_enter() has been invoked with PMAP_CANFAIL and can live with this, or we are close to fandagoland anyways.
2003-02-25	Let pmap_remove_mapping() do its job correctly if option DIAGNOSTIC is	Miod Vallat
	not defined (such as on RAMDISK kernels). Oops.
2003-01-27	Convert m68k pmap from physseg to VM_PAGE_MD.	Miod Vallat
	This allows us to remove some ambiguities on how some functions are called, remove some diagnostic checks for conditions that can never happen and remove the ugly hack with "pmap_initialized". Then, rework internal function interfaces and some logic so as to stop fetching vm_page from a pa and the reverse every now and then - this makes some pmap operations run much faster. per art@'s idea.
2003-01-09	Remove fetch(9) and store(9) functions from the kernel, and replace the few	Miod Vallat
	remaining instances of them with appropriate copy(9) usage. ok art@, tested on all arches unless my memory is non-ECC
2003-01-05	splassert on m68k-based arches. Not totally accurate on hp300 at the moment,	Miod Vallat
	still.
2002-11-05	Add a WEAK_ALIAS macro, to be used by libc/libc_r shortly.	Miod Vallat

2002-10-23	Add a trivial va_copy() macro to all architectures but powerpc	Todd C. Miller
	(which I will leave for Dale since it needs special handling). From NetBSD (and same as sparc64). espie@ OK
2002-10-12	Remove more '\n's from panic() statements. Both trailing and leading.	Kenneth R Westerback
	Diff generated by Chris Kuethe.
2002-10-05	spelling.	Federico G. Schwindt

2002-09-10	Change the pmap_zero_page and pmap_copy_page API to take the struct vm_page *	Artur Grabowski
	instead of the pa. Most callers already had it handy and those who didn't only called it for managed pages and were outside time-critical code. This will allow us to make those functions clean and fast on sparc and sparc64 letting us to avoid unnecessary cache flushes. deraadt@ miod@ drahn@ ok.
