tests/lib/libc/stdio/t_printf: Fix another rounding error.

Noted by kre.

This doesn't break a passing test or fix a failed test, at least on
x86 -- our printf produces `0x1.533p+3' for the double case and
`0xa.99ap+0' for the long double case.  But of the hexadecimal number
literals that that start with 0x5 having three hexadigits to the
right of the fractional point, 0x5.4cdp+1 closest to the IEEE 754
binary64, VAX D, x86 extended precision, and IEEE 754 binary128
floating-point numbers closest to 10.6.

The reason is that the number 10.6 (or the nearest floating-point
number in any format with enough precision) is:

101.0100 1100 1100|1100... * 2^1 = 0x5.4cc|c...p+1

If we round at the vertical bar to the _nearest_ output with three
hexadigits of precision, the result is:

101.0100 1100 1101 * 2^1 = 0x5.4cdp+1

libm: No divtc3.c or multc3.c in sparc64's compat sparc library.

compat/sparc64/sparc/bsd.sparc.mk doesn't define LIBC_MACHINE_CPU,
only LIBC_MACHINE_ARCH, so when the compat build gets to this
conditional, LIBC_MACHINE_CPU is just MACHINE_CPU, i.e., sparc64.

Since there's no `sparc64el' or `sparc64hf-el' that we need to
canonicalize by MACHINE_ARCH -> MACHINE_CPU, just use
LIBC_MACHINE_ARCH here.

Revert various broken changes to printf %La (hldtoa).

This reverts:

hdtoa.c 1.12 (PR/56247: Greg A. Woods: printf("%La", LDBL_MIN) dumps core)
hdtoa.c 1.11 (fix tyop)
hdtoa.c 1.10 (Via enh at google dot com in tech-userlevel. Fix handling of
    EXT_FRAC{H,L}BITS (although we don't need to since we don't have them).)

The underlying motivation for this change was that when ld128 is
decomposed into 4x32 words, this hldtoa logic is broken.

But we don't decompose ld128 into 4x32 words; we decompose it into
6x64 words.

And the change, which was supposed to be a noop in our case of 2x64
words (or similar for x87 80-bit floating-point), broke it to the
point of causing buffer overruns (PR 56247) which when worked around
led to just incorrect output output (PR 56937).

If we want to make the #ifdefs for 4x32 words work, that's fine, but
we absolutely must have automatic test cases to detect this kind of
regression because %La formatting is extremely important for
diagnosing details of floating-point data since it doesn't involve
rounding in binary formats.  For now I've added some trivial tests;
there is a more extensive test suite inside gdtoa that we need to
wire up before anyone tries any other shenanigans in this code.

port-arm/58194: Resurrect vmt(4) from bitrot

On this architecture vmt(4) used to search for a node "/hypervisor" in the
FDT and probed the VMware hypervisor call only when the node was
found. However, things appear to have changed and VMware no longer provides
the FDT node.

Since vmt(4) doesn't actually need to read anything from FDT, and the
hypervisor call logically resides in virtual CPUs themselves, it would be
better to attach it directly to cpu, just like how it's probed on x86.

Fix "stray level 1 interrupt" panic by pressing keys during autoconf(9).

Also explicitly initialize sc->sc_status = HIL_STATUS_BUSY in hil_attach().

Previously hil_intr(9) returned immediately during 'cold', but
all interrupts are enabled at the end of configure() (actually
in MD cpu_configure()) and cold is cleared in confiugre2()
after configure(), so there is a small window when hil interrupts
can be triggered during cold.

It looks there is no problem to process hil_intr() before
hil_attach_deferre() is called via configure2() because
we already check 'sc->sc_status != HIL_STATUS_BUSY' on
processing a kthread.

Fix integer overflow of strtol(3) for "loadpoint" address on ILP32 hosts.

This strtol(3) was introduced in rev 1.12 for PR/57909 after netbsd-10,
but it returns LONG_MAX (0x7FFFFFFF) for 0xFFF00000 on ILP32 hosts and
the wrong loadpoint causes "NOT ENOUGH MEMORY" error by the BOOTROMs
on loading uboot.lif on (at least) my 9000/360 and 9000/425t.

s_rintl.c: Reduce FreeBSD diff and fix on ld128 platforms.

EXT_FRACBITS, the number of bits in the _binary encoding_ that stores
the trailing significand field, is never 113.  In IEEE 754 binary128,
it is 112, even though there are 113 bits of precision in the set of
floating-point numbers -- the leading 1 bit is implicit in binary128.
So ld128 platforms like aarch64 and sparc64 were skipping the real
definition and just defining rintl as an alias for rint, which is
wrong.

In contrast, LDBL_MANT_DIG, the number of bits of precision in the set
of floating-point numbers (p, in IEEE 754 parlance), is 113 in IEEE 754
binary128.  This is also the constant used in FreeBSD libm anyway.  So
let's just use that instead of trying to translate it to our private
EXT_FRACBITS (not defined in FreeBSD) with a fencepos terror.  And
delete the buggy rintl=rint alias.

radixtree: allocate memory with KM_NOSLEEP to prevent pagedaemon hangs

Revert the part of rev 1.32 (reapplying "Do away with separate pool_cache
for some kernel objects") that changed the memory allocation for radixtree
nodes from PR_NOWAIT to KM_SLEEP as part of changing from a pool to kmem.
uvm_pageinsert_tree() calls into the radixtree code while holding
the object's vmobjlock, but that same lock is taken by the pagedaemon
in the process of reclaiming pages, and if the pagedaemon happens to
choose the same object to reclaim from that uvm_pageinsert_tree()
is being called on, then these two threads will deadlock.
The previous code already handled memory allocation failures
in uvm_pageinsert_tree() so we can simply change it back to nosleep.

Fixes a hang reported by simonb@, and the fix was also tested by him.

Add a device tree for the Red Pitaya SDRlab 122-16.

To boot NetBSD on the 122-16, copy the .dtb built from
zynq-red-pitays-122-16.dts, the first-stage bootloader (called
boot.bin) and U-Boot that came with the 122-16 and a kernel image,
netbsd.ub, built for earmv7hf to an MS-DOS partition on an
MBR-partitioned SD card.  At the U-Boot prompt, "Zynq> ", type these
commands:

i2c dev 0
eeprom read 0 0x50 0 0x1804 0x400
env import -b 0 0x400 hw_rev serial ethaddr
setenv bootargs "root=ld0a"
fatload mmc 0 0x01f00000 device~1.dtb
fatload mmc 0 0x02000000 netbsd.ub
fdt addr 0x01f00000
fdt set /axi/ethernet@e000b000 local-mac-address $ethaddr
bootm 0x02000000 - 0x01f00000

Note that the ethernet PHY will not attach unless you have applied
the patches from Lloyd Parkes in kern/58083.

Initialize `struct consdev` members cn_dev and cn_pri like other
UART drivers do.  If cn_dev is 0 instead of NODEV, then the kernel
may redirect console writes to major 0, minor 0, which is /dev/mem.

console message in this way.

Add dhcpcd to riscv ramdisk, etc.

Be consistent with configs for pretty much every other (modern) arch

surprised (as happened relatively recently with evbmips images). This
means of course we also need bpf.

While here, add a few wedge devices, too. This aligns us with the
device definitions evbmips uses (that appears to be where the riscv
Makefile was copied from back in 2015).

Even though the test only uses fixed-size types, lint's computed size of

are wrong, probably due to the unrelated struct declaration above, as
already mentioned in the comments.

lint: measure the alignment in bytes, not bits

While measuring the alignment in bits makes sense when building a struct
type with bit-fields, in all other places it is more confusing than
helpful.

The only visible change is that in debug mode, the format of type sizes
and alignment changed.  Since the size of all complete types is a
multiple of a byte (as defined in the C standard), sizes and alignments
are reported in bytes as well.  Only while a struct is being built, the
type size may include an additional '+x' for the bits of a bit-field.
