Added BUS_DMA_COHERENT flag to bus_dmamem_map() to improve stability on aarch64.

In ixgbe, TX/RX descriptor rings are configured in 16-byte units.
If BUS_DMA_COHERENT is not specified, cpu cache (writeback/invalidate)
operations by bus_dmamap_sync() in aarch64 (arm/arm32/bus_dma.c) are done per
cache line size (usually 64 bytes). As a result, adjacent descriptors conflict
with the DMA operation, resulting in unstable operation.

To avoid this, descriptors area should be mapped as non-cache with BUS_DMA_COHERENT.

With the (very) recent changes to printf(1), a numeric conversion from data
of the form '+1 (two (or more) characters after the quote) will now generate
an error message, and cause printf(1) to exit(1) when it is done.

Adapt the test cases which use that data form to handle that.

(kre)

Handle the (very) recent change to printf(1) - when writing to a closed
stdout printf(1) now issues an error message, hence stderr in such cases
should not be empty, rather than should be empty.  Adapt to that.

(kre)

Changes for POSIX conformance.

1.  exit(1) with an error message on stderr if an I/O error occurs.
1a. To work properly when built into /bin/sh sprinkle clearerr() at
    appropriate places.

2.  Verify that when a 'X data value is used with one of the numeric
    conversions, that nothing follows the 'X'.  It used to be unclear
    in the standard whether this was required or not, it is clear that
    with numeric conversions the entire data value must be used, or an
    error must result.  But with string conversions, that isn't the case
    and unused parts are simply ignored.  This one is a numeric conversion
    with a string value, so which applies?  The standard used to contain
    an example of '+3 being converted, producing the same as '+ ignoring
    the '3' with no mention of any error, so that's the approach we adopted,
    The forthcoming version now explicitly states that an error would also
    be generated from that case, as the '3' was not used by the numeric
    conversion.

2a. We support those conversions with floating as well as integer conversions,
    as the standard used to suggest that was required (but it makes no sense,
    the values are always integers, printing them in a floating format is
    dumb).  The standard has been revised to make it clear that only the
    integer numeric conversions %d %u %x (etc) are supposed to handle the 'X
    form of data value.  We still allow it with the floating formats as an
    extension, for backward compat, just in case someone (other than the ATF
    tests) is using it.  It might go away.

2b. These formats are sypposed to convert 'X where 'X' is a character
    (perhaps multibyte encoded) in the current LC_CTYPE locale category.
    We don't handle that, only 1 byte characters are handled currently.
    However the framework is now there to allow code to (one hopes, easily)
    be added to handle multi-byte locales.  (Note that for the purposes of
    #2 above, 'X' must be a single character, not a single byte.)

(kre)

Don't describe "%%: in the format as a format conversion, it isn't,
it is an escaped literal '%' character.  None of what applies to
format conversions applies to this.

(kre)

Fix a truly embarrassing quoting screwup.  There is an explanation as
to why this didn't cause any failures, but I won't go into it here.
This was detected by the about to be committed printf changes.

While here also correct a couple of minor comment layout issues.

(kre)

Catch up with /bin/sh built-in echo ... if a write error occurs,
don't just exit(1), write an error message to stderr as well
(required for POSIX conformance).

Fix a bug in the built-in echo in /bin/sh reported in private mail by
Oguz <oguzismailuysal@gmail.com>

If echo detects an I/O error, it does exit(1) (that's fine) but then
the next echo also does exit(1) even without any errors of its own,
and every following echo writing to stdout does the same thing.

eg:

echo foo >&- ; echo $?; echo $?; ( echo $( echo $?; echo $?) ; echo $? )
1
1
1 1
1

The first echo writes nothing (stdout is closed) but does exit(1).
The second echo writes "1" (correct, the exit status of the previous
echo) and should exit(0) - but doesn't.  This pattern continues...

While here, conform to the POSIX requirement on echo (and many other
standard utilities, but definitely not all) that when the utility
does exit(>0) a message must be written to stderr (and vice versa
in many cases).  Our echo (as shown above) did the exit(1) part
when it detected the I/O error, but no message is sent to stderr.
Fix that while we're here.

Similar changes are required for /bin/echo (coming soon), and
/usr/bin/printf (which is also the sh builtin printf) - except
currently that one kind of conforms, as it ignores errors writing
to stdout (as do large numbers of other utilities).  For many
programs that's kind of acceptable, but where the sole purpose of
the program is to write to stdout, it really isn't.  Also to be
fixed soon.

(kre)

Add two new sub-tests to the echo test case of the t_builtins shell ATF test.

The first verifies that echo exits >0 when it encounters an I/O error on
its output (this part would have succeeded for a long time).  It also
verifies the POSIX requirement that when most standard utilities (or
perhaps many rather than most) exit(>0) they must write a message to stderr.
Our sh's built in echo did not do that (nor does /bin/echo but that's not
relevant here).

The second demonstrates (on an unfixed built-in echo) a bug reported in
private e-mail by Oguz <oguzismailuysal@gmail.com> where once an instance of
the built-in echo has detected an I/O error, all later invocations of
the built-in echo, with no I/O errors of their own, also exit(1) (the error
status on stdout is not cleared, each echo sees the "I/O error occurred" and
does exit(1)).

In this second sub-test, the "2>&-" on the first echo command is simply
an artifact caused by the test harness - the "check" function verifies
that exit((>0) requires a message on stderr (and vice versa), but that
only applies to most (or many) utilities, echo is one, but sh is not.
In the second test, the exit status comes from sh - sh is permitted to
write to stderr (via the echo command it runs in this case) and still
exit(0).  But the check function in the test does not understand that
subtlety.  So, we simply suppress the stderr message by closing stderr
(the first of these two new sub-tests has verified that the message exists)..

move bi-endian disklabel support from the kernel and libsa into libkern.

- dkcksum() and dkcksum_sized() move from subr_disk.c and from
  libsa into libkern/dkcksum.c (which is missing _sized() version),
  using the version from usr.sbin/disklabel.

- swap_disklabel() moves from subr_disk_mbr.c into libkern, now called
  disklabel_swap().  (the sh3 version should be updated to use this.)

- DISKLABEL_EI becomes a first-class option with opt_disklabel.h.

- add libkern.h to libsa/disklabel.c.

this enables future work for bi-endian libsa/ufs.c (relevant for ffsv1,
ffsv2, lfsv1, and lfsv2), as well as making it possible for ports not
using subr_disk_mbr.c to include bi-endian disklabel support (which,
afaict, includes any disk on mbr-supporting platforms that do not have
an mbr as well as disklabel.)

lint: add more specific warning for bit-field of type plain 'int'

Previously, declaring a bit-field of type plain 'int' resulted in this
warning:

warning: nonportable bit-field type 'int' [34]

This warning was too unspecific to be actionable, and until yesterday it
didn't even include the type.  In order to allow this warning to be
understood and properly fixed, describe the actual nonportability more
precisely:

warning: bit-field of type plain 'int' has
implementation-defined signedness [344]

(rillig)

lint: add type information to unportable bit-field type

Seeing the message "unportable bit-field type 'int'" may sound strange
at first, but that's a strict interpretation of the wording in C99
6.7.2.1p4, which requires that the bit-field type is "'_Bool', 'unsigned
int' or 'signed int', or some other implementation-defined type".

The rationale for C99 6.7.2.1 explicitly lists plain 'int' among the
allowed types for bit-fields, regardless of any additional
implementation-defined types.  This means that lint had interpreted this
paragraph wrong, and it should be fixed to allow plain int as well.

(lukem)

SPD stands for "Serial Presence Detect".  This implies that
if we're using direct configuration that we should treat
that as a *hint*... it's entirely possible that a device
tree lists locations where SPD memory can be found, not
necessarily where memory is known to be present.

Accordingly, if we get a direct configuration match based
on compatible data or device name, we still check to see
if the device is there.

Update the pcfiic driver for the new i2c device enumeration scheme.
Push the multiple-channels complexity up into the ebus front-end,
as that specific to a particular Sun model of controller.  Now
the BBC-type controllers get multiple I2C bus instances attached to
them.

Keep m_len and m_pkthdr.len consistent to prevent panic on arm.

  Arm's bus_dmamap_load_mbuf() keeps a pointer to the original mbuf
  and bus_dmamap_sync() refers it. ixgbe_rxeof() modified mbuf's m_len
  inconsistently with m_pkthdr and dm_mapsize. "ifconfig down up" made
  panic by referring the inconsistent mbuf length.

No need to device_set_handle(); it's done for us by the i2c enumeration
code.

Adapt jbusi2c to the new i2c device enumeration scheme.

Do that again, but slightly differently: a "compatible" property is
required by the Device Tree i2c bindings, and is present on all of
the Sun i2c device nodes that are useful (the notable exception being
the i2c "idprom" nodes, which are actually duplicates of a regular
serial eeprom node).  However, Apple's older OpenFirmware implementations
are rife with i2c nodes that lack a "compatible" property.  So, define
a OFW_I2C_ALLOW_MISSING_COMPATIBLE_PROPERTY quirk, and enable it in
the __HAVE_OPENFIRMWARE_VARIANT_AAPL case.

(thorpej)

Ooops, no, revert that.

(thorpej)

Skip nodes without a "compatible" property.

(thorpej)

Define __HAVE_OPENFIRMWARE_VARIANT_SUNW for sparc64 systems and handle
its OpenFirmware quirks with respect to i2c:

- "reg" property is 2 cells, the first one containing the channel the
  device is on, the second one containing the i2c device address.
- The i2c device address is shifted left 1 bit to account for the r/w
  bit on the wire.

Comment out flow director processing in fast path.

ixgbe_xmit() is per-queue fast path.  It should reduce access to
per-device data (adapter->feat_en).

(knakahara)

Move the bus/channel number for multi-channel / mux controllers out of
i2cbus_attach_args and stash it in the i2c_tag_t instead.  This makes it
accessible to platform device tree code when enumerating devices.

(thorpej)

Deal with quirks / differences in OpenFirmware implementations'
interpreation of the i2c "reg" property by embedding knowledge
of those quicks directly, rather than forcing lots of drivers
to provide their own devhandle implementations.  We default to
assuming the Device Tree bindings, and tweak based on platform-
specific #ifdefs.

Start with __HAVE_OPENFIRMWARE_VARIANT_AAPL (all i2c "reg" properties
encode an address that's shifted left 1 bit to account for the R/W bit
that appears on the wire).

ntfs_loadntnode(): Use bread() when ntm_sysvn[NTFS_MFTINO] is NULL.

May happen when loading node 0 (MFT) during mount and some
attributes are stored in another ntnode.

We do not match machines whose SWIM does not support the IWM register
set used by this driver (SWIM II/III, SWIM behind IOP, AV models' DMA
based controllers).  Unfortunately, this distinction does not run
cleanly along MACH_CLASS* lines, and we have to look at MACH_MAC{model} tags.

Fix the wrong state check

After disconnection from PPPoE server, the client waits for
reconnection in initial state or reconnects in PADI state.

(yamaguchi)

Change reconnect delay after PADT received (15 sec -> 5 sec)

5 sec is the same as minimum PADI resending interval
