While experimenting with changing boolean_t to another type, I noticed
that several powerpc pmap related functions returned the wrong type:
boolean_t instead of int.
Fix several declarations and definitions to match the actual pmap
function types: pmap_dev_direct_mapped_t and pmap_ts_referenced_t.

Rather than having a tool in the FreeBSD base system for obtaining
the FreeBSD ports tree, users are encouraged to `pkg install git`
and then `git clone https://git.FreeBSD.org/ports.git /usr/ports`.
The portsnap servers will continue operating until FreeBSD 13 reaches
its End-of-Life, and portsnap is available from the ports tree as

We want to be able to build some host tools for non-FreeBSD hosts
without building more than we need. The DIRDEPS_BUILD lets us
do that.
We use the pseudo MACHINE "host" when building
for the host - deal with that when setting _host_arch.

The whole point of the DIRDEPS_BUILD is to avoid tree walks
and basically build everything in a single pass.
We use the pseudo MACHINE "host" to represent the build host.
When the build host is not FreeBSD or is an older version of FreeBSD
it may need some help to build host-tools.
The directory tools/build does this - building libegacy.
local.sys.mk: create a pseudo option MK_host_egacy to indicate
if tools/build needs to be built for "host".
local.dirdeps.mk: set MK_host_egacy.host to ${MK_host_egacy}
all other DEP_MACHINES will get "no"
This allows a Makefile.depend.options in makefs etc to cause tools/build
to be built for host but only if necessary.
local.init.mk: use ISYSTEM as arg to -isystem so that it can be overridden.
The default remains ${STAGE_INCLUDEDIR}
src.init.mk: if MACHINE is host and we are not FreeBSD
set some MK_ flags the same as tools/build/mk/Makefile.boot.pre and
include src.init.${.MAKE.OS:tl}.mk if it exists.
For older versions of FreeBSD add libegacy when building PROGs for "host"
Also instead of -isystem${STAGE_INCLUDEDIR} we want
-I${STAGE_INCLUDEDIR} and -isystem/usr/include so we override ISYSTEM.
This means any headers we stage for "host" will take precedence over
system headers but #include_next will DTRT.
src.init.linux.mk: add
-I${SRCTOP}/tools/build/cross-build/include/linux
and generally deal with building host tools on Linux.
Eg. static linking does not work so set NO_SHARED= no
Override some HAVE_ flags.
src.sys.env.mk: on linux awk throws an warning about # in newvers.sh
just send stderr to /dev/null

The other stacks it turns out actually expect the output to be called and can become stuck if it is
not. This is because they run there timer code from there and the input routine does not always
assure a timer is running. The real longterm fix here might be to go into the other stacks (rack and bbr)
and make sure that a timer is running after input if you don't do output.. as well as call the timer functions.
This would cut down on calls from hpts. But I think its too dramatic of a change for the immediate time.

Before the commit 6cc44223cb the
field event_mask was fully copied to the EventMasks field.
After this commit the event_mask (uint8_t) is 4 times casted to
EventMask (uint32_t). Because of that 24 bits of each event_mask array
is lost.
This commits brings back simple copying of field, and after words
converting 32 bits field to the requested endian.
I don't think we need more sophisticated method,
as the array is of size 4 (for 32 bits version).

Commit 3e0856b63f updated
__sg_alloc_table_from_pages to use the same API as linux, but modified
the loop condition when going over the pages in a sg list. Part of the
change included moving the sg_next call out of the for loop and into the
body, which causes an off by one error when traversing the list. Since
sg_next is called before the loop body it will skip the first element
and read one past the last element.
This caused panics when running PRIME with nvidia-drm as the off-by-one
issue causes a NULL dereference.

The 4.2 sigreturn was a bit of a enima so the 4.2 was remove. Regenerate
to cope the very minor changes in comments and one string.
Sponsored by: Netflix
Back in 4.3BSD, the system call table wasn't generated, and there was an
entry:
"4.2 sigreturn", /* 139 = old 4.2 sigreturn */
This got converted to
139 OBSOL 0 4.2 sigreturn
in 4.3 RENO. Since it was obsolete, nothing bad happened. In fact,
there was code in makeyscalls.sh to cope:
{ comment = $4
for (i = 5; i <= NF; i++)
comment = comment " " $i
if (NF < 5)
$5 = $4
}
so the generated comment in syscalls.c was almost correct:
"obs_4.2", /* 139 = obsolete 4.2 sigreturn */
a bug that we have to this very day, despite makesyscalls.sh being
rewritten in lua.
However, this historical wart is the only place in our current
syscalls.master file where we have an extra field for the 'not
generated' class of system calls. Remove the historical wart so that the
re-write of makesyscalls.lua can be simpler (so, I hope, qemu's bsd-user
can large swathes of code automatically generated too). This should help
make things more understandable (changes to simplify makesyscalls.lue
aren't quite debugged, so have to wait for another day).
There's 3 different obsolete sigreturns (but only 1 that was ever in
FreeBSD 2.x and newer).
