361179df26 Make debugging decisions at run-time, and place a handy DDB breakpoint 
after a transfer has been mapped in the page table.

2981fec2f0 Allow specification of a minimum page table alignment to alpha_sgmap_init(). 
This is to work around an apparent hardware bug in some 2117x chipsets
where the page table must be aligned to at least 32k.

9d3aef5632 Put each of two labels one line to early. That could cause a panic, 
if the wdc space couldn't be mapped.  Pointed out by fvdl@netbsd.org.

ifconfig media warning with GENERIC kernels, as well as simply being
more correct.)

28fa7254b3 Define the O_SYNC flag to open(2) per XPG4.2, using the same value as the 
historic O_FSYNC flag (the semantics are identical).  Hide the historic
O_FSYNC flag if _POSIX_SOURCE or _XOPEN_SOURCE are defined, and define it to
be O_SYNC.

cgd
3b207eaf83 add support for an ATAPI attachment for 'sd'. 
fix 'cd' driver's NCD_SCSI bogosity (was using testing wrong macro!)
clean up in various ways:
* make common atapi_mode_{sense,select}() functions.
* put ATAPI data structures in more sensible headers, split up by
  device type.
* include headers a bit more carefully.
* pass flags to attachment-specific cd functions, and use them.
* get rid of SCSI bits in scsipi_base.h's scsipi_make_xs(), move
  them into the correct place in scsi_base.c.
* fix minor typo in struct name in scsipiconf.h (which was apparently
  never used except in a #define later in the same file).
* use __attribute__ to force 4-byte alignment for xs command store,
  so that architectures trying to bus_space_write_multi_N() (where
  N > 1) that data to a controller won't lose.
* clean up a few comments in typos, and make a few #defines easier to
  understand/maintain.
* rename cd_link.h to cdvar.h (via repository copy).  This is exactly
  what a 'var' file is supposed to be.

aaede4d8d8 Various cleanups and bug fixes to the wdc/wd code: 
* Fix bug in wdc that would overflow ATAPI transfer length.
* Improve wdc probe code so that 'wdc' is probed in if present
  even if there are no drives attached, and so that it works
  properly even if the only device is an ATAPI slave.
* bus_space-ify.
* split the ISA attachment from the wdc driver, and remove
  ISA dependencies from non-ISA files.
* claim that wd and wdc are now machine-independent (probably not
  completely true, but mostly so; they at least work on arm32 and
  i386).
* Various other minor fixups and cleanups, some of which were pointed
  out by Kazuki Sakamoto.

ad141a69a7 Shuffle wd/wdc driver files around (via repository copies). wdc 
now lives in dev/ic, wd now lives in dev/ata.  there's now a 'ata'
interface attribute defined in conf/files, but wdc can't go there
yet because some ports still use private versions based on the old
ISA version.

561056f2e2 Grab a fix from 4.4BSD-Lite2: open(2) with O_FSYNC and MNT_SYNCHRONOUS 
had not effect.  Fix: check for either of these flags in vn_write(),
and pass IO_SYNC down if they're set.
