48734c99d3 Convert pointers obtained from the threadattr_t structure with TO_PTR().
In all of these source files, the userspace pointer size corresponds
with the kernelspace pointer size, meaning that casting directly works.
As I'm planning on making 32-bit execution on 64-bit systems work as
well, use TO_PTR() here as well, so that the changes between source
files remain minimal.

647672e21f Skip ls tests that use sparse files if these are not supported.
Some of the ls(1) tests create really large sparse files to validate
the number formatting features of ls(1).  Unfortunately, those tests fail
if the underlying test file system does not support sparse files, as is the
case when /tmp is mounted on tmpfs.

Before running these tests, check if the test file system supports sparse
files by using getconf(1) and skip them if not.  Note that the support for
this query was just added to getconf(1) in r304694.

1a58327bc3 Fix key delay and repeat, part 2.
Use sbintime_t timeouts with precision control to get very accurate
timing.  It costs little to always ask for about 1% accuracy, and the
not so new event timer implementation usual delivers that, and when
it can't it gets much closer than our previous coarse timeouts and
buggy simple countdown.

The 2 fastest atkbd repeat rates have periods 34 and 38 msec, and ukbd
pretended to support rates in between these.  This requires
sub-microsecond precision and accuracy even to handle the 4 msec
difference very well, but ukbd asked the timeout subsystem for timeouts
of 25 msec and the buggy simple countdown of this gave a a wide range
of precisions and accuracies depending on HZ and other timer
configuration (sometimes better than 25 msec but usually more like 50
msec).  We now ask for and usually get precision and accuracy of about
1% for each repeat and much better on average.

The 1% accuracy is overkill.  Rounding of 30 cps to 34 msec instead of
33 already gives an error of +2% instead of -1%, and ut AT keyboards on
PS/2 interfaces have similar errors.

A timeout is now scheduled for every keypress and release.  This allows
some simplifications that are not done.  It allows removing the timeout
scheduling for exiting polled mode where it was unsafe in ddb mode.  This
is done.  Exiting polled mode had some problems with extra repeats.  Now
exiting polled mode lets an extra timeout fire and the state is fudged
so that the timeout handler does very little.

The sc->time_ms variable is unsigned to avoid overflow.  Differences of
it need to be signed.  Signed comparisons were emulated by testing an
emulated sign bits.  This only works easily for '<' comparisonss, but
we now need a '<=' comparison.  Change the difference variable to
signed and use a signed comparison.  Using unsigned types here didn't
prevent overflow bugs but just reduced them.  Overflow occurs with
n repeats at the silly repeat period of [U]INT_MAX / n.  The old countdown
had an off by 1 error, and the simplifications would simply count down
1 to 0 and not need to accumulate possibly-large repeat repeats.

60152a4037 Fix system hang when large FDT is in use
Summary:
Kernel maps only one page of FDT. When FDT is more than one page in size, data
TLB miss occurs on memmove() when FDT is moved to kernel storage
(sys/powerpc/booke/booke_machdep.c, booke_init())

This introduces a pmap_early_io_unmap() to complement pmap_early_io_map(), which
can be used for any early I/O mapping, but currently is only used when mapping
the fdt.

2f5007f6d2 LC_*_MASK bit shifting order was partially broken from the initial commit
time at year 2012. Only LC_COLLATE_MASK and LC_CTYPE_MASK are in the
right order.

The order here should match XLC_* from "xlocale_private.h" which, in turn,
match LC_* publicly visible order from <locale.h> which determines how
locale components are stored in the structure.
LC_*_MASK -> XLC_* translation done as "ffs(mask) - 1" in the querylocale()
and equivalent shift loop in the newlocale(), so mapped to some wrong
components (excluding two mentioned above).

Formally the fix is ABI breakage, but old code using those masks
never works properly in any case.
Only newlocale() and querylocale() are affected.

e99472e0d6 Fix key delay and repeat, part 1.
kbdcontrol -r fast is documented to give a non-emulated atkbd's fastest
rate of 250.34, but is misimplemented to request this as 0.0.  ukbd
supports many nonstandard rates, although it is currently too inaccurate
by a factor of several hundred for non-huge nonstandard rates to be
useful.  It mapped 0.0 to 200.0.  A repeat delay of 0 means a rate of
infinity which is quite fast, but physical constraints limit this to
a few MHz and the inaccuracies made it almost usable.

Convert 0.0 to the documented 250.34.

Also convert negative args and small args to the 250.34 minimal ones,
like atkbd does.  This is for KDSETREPEAT -- the 2 versions of the
deprecated KDSETRAD have bounds checking.  Keep not doing any bounds
checking or conversions for upper limits since nonstandard large
delays are useful for testing.

The inaccuracies are dependent on HZ and the timeout implementation.
With the old timeout implementation and HZ = 1000, 200.0 probably
worked better to emulate 250.34 than 250.34 itself.  HZ = 100 gives
roundoff errors that accidentally reduce the inaaccuracies, and
event timers reduce the inaccuracies even more, so 200.0 was giving
more like itself (perhaps 215.15 on average but sometimes close to
10 msec repeat which is noticebly too fast).  This commit makes 0.0
noticeably too slow, like 250.34 always was.

c30c436a58 FAST_DEPEND: Fix 'make all install' not properly rebuilding based on .depend.* files.
An optimization is in place to skip reading the .depend.* files with
'make install'.  This was too strong and broke 'make all install' and
'make foo.o foo install'.  Now only skip reading the dependency files
if all make targets ran are install targets.

The problem comes about because headers are only added in as a guessed
dependency if .depend.* files do not yet exist.  If they do exist, even
if being skipped from being read, then the header dependencies are not
applied.  This applies to all #included files, and not just headers.

4d611b2b2d Fix in-tree GCC builds after r304681.
There were a few issues.
- In-tree GCC won't have X_COMPILER_TYPE defined but will have
  WANT_COMPILER_TYPE==gcc set from the SYSTEM_COMPILER logic that can
  be used.  Make the clang check specific to clang as well to ensure
  -target doesn't leak into a GCC build.
- When using a cross-compiler GCC (with a default sysroot or arch) and also
  passing --sysroot, it basically forgets all internal paths for
  libraries.  We've already worked around this quite a bit for
  the external toolchains.  Now for the in-tree bootstrap cross-compiler
  GCC, also pass in the needed -B${WORLDTMP}/usr/lib to find the crt
  object files, but also -isystem and -L to fix the paths.  This creates
  quite a spammy build log, but it is clear and still achieves the goals
  and stays consistent between internal and external build flags.
  Reducing the spam by using the '=' prefix feature will help and be
  done later.

bb0cd1b514 Always pass in -target and --sysroot flags for the build.
The internal bootstrap compiler has a default sysroot set by TOOLS_PREFIX
and target set by TARGET/TARGET_ARCH.  However, there are several needs to
always pass an explicit --sysroot and -target.
- External compiler needs sysroot and target flags.
- External ld needs sysroot.
- To be clear about the use of a sysroot when using the internal compiler.
- Easier debugging.
- Allowing WITH_SYSTEM_COMPILER+WITH_META_MODE to work together due to
  the flip-flopping build command when sometimes using external and
  sometimes using internal.
- Allow using no lld which has support for default paths.

The default sysroot in the bootstrap compiler is not changed.  The
buildenv compiler will still work with its default and will also
include -target/--sysroot from CC in the environment.

Summary:
There is no need to call tlb1_init() twice. Now it is called first time from
booke_init() and second time from powerpc_init() (where it is under BOOKE
switch). Although this does not cause immediate problems in the mainline kernel,
this can lead to undesirable side effects like two TLB entries with the same VA
in the TLB1. Presence of two TLB entries with the same VA can hang CPU.

Test Plan:
Add initial mapping for UART to the tlb1_init(), build and boot the kernel,
ensure that mapping presents only once (most convinient way - through Lauterbah
or similar hardware debugger)
