Revision	Date	Author	Comments
1.7	04-Dec-2016	maxv	KNF and explain a few things
1.6	16-Jun-2011	joerg	branches: 1.6.12; 1.6.30; 1.6.34; Add an optional MD calling convention flag for use in libsa when space optimisation is critical. Use this on i386 to switch to register passing calling convention for the file system entry points and most assembler call backs that have to preserve at least 3 registers.
1.5	20-Feb-2011	jakllsch	branches: 1.5.2; %bl is part of %bx, %bx contains the address we requested from the BIOS. Thus, use %cl instead of %bl for return value storage.
1.4	21-Nov-2009	dsl	branches: 1.4.4; 1.4.6; 1.4.8; Preserve %ds over bios calls. Not strickly necessary because real_to_prot doesn't normally rely on in. However it caused much confusion while debugging, and does no harm.
1.3	28-Apr-2008	martin	branches: 1.3.14; Remove clause 3 and 4 from TNF licenses
1.2	05-Feb-2003	dsl	branches: 1.2.104; 1.2.106; 1.2.108; Change to use .codw16/32 and ensure buffer address <64k (approved by christos)
1.1	23-Jan-2003	jdolecek	add another memory size detection routine, using int15, function 0xc7, which is supported on later IBM PS/2 models; this is necessary to detect memory over 64MB thanks go to Pavel Cahyna for testing on his IBM PS/2 machine with 128MB bump biosboot version to 2.15
1.2.108.2	11-Mar-2010	yamt	sync with head
1.2.108.1	16-May-2008	yamt	sync with head.
1.2.106.1	18-May-2008	yamt	sync with head.
1.2.104.1	02-Jun-2008	mjf	Sync with HEAD.
1.3.14.3	27-Aug-2011	jym	Sync with HEAD. Most notably: uvm/pmap work done by rmind@, and MP Xen work of cherry@. No regression observed on suspend/restore.
1.3.14.2	28-Mar-2011	jym	Sync with HEAD. TODO before merge: - shortcut for suspend code in sysmon, when powerd(8) is not running. Borrow ``xs_watch'' thread context? - bug hunting in xbd + xennet resume. Rings are currently thrashed upon resume, so current implementation force flush them on suspend. It's not really needed.
1.3.14.1	24-Oct-2010	jym	Sync with HEAD
1.4.8.1	05-Mar-2011	bouyer	Sync with HEAD
1.4.6.1	06-Jun-2011	jruoho	Sync with HEAD.
1.4.4.1	05-Mar-2011	rmind	sync with head
1.5.2.1	23-Jun-2011	cherry	Catchup with rmind-uvmplock merge.
1.6.34.1	07-Jan-2017	pgoyette	Sync with HEAD. (Note that most of these changes are simply $NetBSD$ tag issues.)
1.6.30.1	05-Dec-2016	skrll	Sync with HEAD
1.6.12.1	03-Dec-2017	jdolecek	update from HEAD
