f01bf63b42 If the maximum payload size is 256 bytes or more, set the DMA write
water mark to 256 bytes.  Otherwise controller will encounter DMA
write under run errors and would result in RX DMA hang. If the
maximum payload size is 128 bytes, the water mark is set to 128
bytes as usual.
While here, set maximum read request size to 2048 for BCM5719/BCM5720.
For other PCIe devices, use 4096. And reprogram the maximum read
request size whenever device reset is performed.

a93c5f8727 Add an echo to say we're "Booting..." when the overloaded "boot" Ficl word is
executed to better differentiate between loader-specific errors and kernel-
specific errors (if ever any of either).

This type of functionality hasn't been required before the introduction of the
advanced menu system (r222417). Adding this functionality will help different-
iate errors at the loader-level such as a BTX halt caused by heap exhaustion
and errors that may be involved with executing the kernel (wrong architecture
for example). A user can learn that messages before "Booting..." are related to
the loader(8) environment and it's Forth-ilk, while those after are not
related to loader(8) -- the point that loader(8) has ``left the building''.

This patch also includes a man-page update to color.4th(8) as the color logic
moves to a lower-level (from being included by beastie.4th to being included
by loader.4th).

After noticing a delay between execution of the overloaded "boot" FICL word and
the display of text on-screen, gcooper confirmed that the introduction of a
builtin memory test (disabled by adding hw.memtest.tests="0" to loader.conf(5))
was the cause of the delay.

This patch adds an echo to produce "Booting..." when the overloaded "boot" word
is executed (this includes from the interactive command-prompt on all arches,
from the menu system on arches that run the beastie menu, and even those arches
that run the menu but disable it by setting beastie_disable="YES" in
loader.conf(5)). When loader_color="YES" in loader.conf(5), the same message is
produced but in white text on a blue background (only the letters produced have
this background -- opposed to perhaps the entire line).

41b1f8207c In a few places, like the implementation of ptrace(), a thread may call
upon pmap_enter() to create a mapping within a different address space,
i.e., not the thread's own address space.  On i386, this entails the
creation of a temporary mapping to the affected page table page (PTP).  In
general, pmap_enter() will read from this PTP, allocate a PV entry, and
write to this PTP.  The trouble comes when the system is short of memory.
In order to allocate a new PV entry, an older PV entry has to be
reclaimed.  Reclaiming a PV entry involves destroying a mapping, which
requires access to the affected PTP.  Thus, the PTP mapped at the
beginning of pmap_enter() is no longer mapped at the end of pmap_enter(),
which leads to pmap_enter() modifying the wrong PTP.  To address this
problem, pmap_pv_reclaim() is changed to use an alternate method of
mapping PTPs.

Update a related comment.

9086143e8c After r241245 it appeared that in_delayed_cksum(), which still expects
host byte order, was sometimes called with net byte order. Since we are
moving towards net byte order throughout the stack, the function was
converted to expect net byte order, and its consumers fixed appropriately:
  - ip_output(), ipfilter(4) not changed, since already call
    in_delayed_cksum() with header in net byte order.
  - divert(4), ng_nat(4), ipfw_nat(4) now don't need to swap byte order
    there and back.
  - mrouting code and IPv6 ipsec now need to switch byte order there and
    back, but I hope, this is temporary solution.
  - In ipsec(4) shifted switch to net byte order prior to in_delayed_cksum().
  - pf_route() catches up on r241245 changes to ip_output().

bfb53c205c Make graid command line a bit more friendly by allowing volume name or
provider name to be specified instead of geom name (first argument in all
subcommands except label).  In most cases there is only one array used
any way, so it is not really useful to make user type ugly geom names like
Intel-f0bdf223 or SiI-732c2b9448cf.  Though they can be used in some cases.

1a947de79c Use the RTC unit to get the time. This works on all known AT91SAM9*
processors, either on reboot or after power down with battery backup.
However, the AT91RM9200 RTC always resets on reboot making it just
about useless at the moment (if we support a low-power mode or an
extended sleep mode, it might become useful).

52e7fd7c54 Add support for bmake. This includes:
1.  Don't do upgrade_checks when using bmake. As long as we have WITH_BMAKE,
    there's a bootstrap complication in ths respect. Avoid it. Make the
    necessary changes to have upgrade_checks work wth bmake anyway.
2.  Remove the use of -E. It's not needed in our build because we use ?= for
    the respective variables, which means that we'll take the environment
    value (if any) anyway.
3.  Properly declare phony targets as phony as bmake is a lot smarter (and
    thus agressive) about build avoidance.
4.  Make sure CLEANFILES is complete and use it on .NOPATH. bmake is a lot
    smarter about build avoidance and should not find files we generate in
    the source tree. We should not have files in the repository we want to
    generate, but this is an easier way to cross this hurdle.
5.  Have behavior under bmake the same as it is under make with respect to
    halting when sub-commands fail. Add "set -e" to compound commands so
    that bmake is informed when sub-commands fail.
6.  Make sure crunchgen uses the same make as the rest of the build. This
    is important when the make utility isn't called make (but bmake for
    example).
7.  While here, add support for using MAKEOBJDIR to set the object tree
    location. It's the second alternative bmake looks for when determining
    the actual object directory (= .OBJDIR).
