db50a77a61 Revert r322418, LDBL_MAX_EXP unsuitable for macro pasting on some arches
Either need a different way to spell HALF_LDBL_MAX, or a different way
to spell LDBL_MAX_EXP, or a different approach.

d68f9d50f6 Improve standard compliance for memset_s() and abort_handler_s().
abort_handler_s() currently simply calls abort(), though the standard
specifies more: "Writes an implementation-defined message to stderr
which must include the string pointed to by msg and calls abort()."

memset_s() is missing error condition "n > smax", and does not invoke
the constraint handler after filling the buffer: "following errors are
detected at runtime and call the currently installed constraint
handler function after storing ch in every location of the destination
range [dest, dest+destsz) if dest and destsz are themselves valid",
one of the errors is "n > smax" itself.

9561259347 lib/msun: avoid referring to broken LDBL_MAX
LDBL_MAX is broken on i386:
https://lists.freebsd.org/pipermail/freebsd-numerics/2012-September/000288.html

Gcc has produced +Infinity for LDBL_MAX on i386 and amd64 with -m32
for some time, and newer versions of gcc are now warning that the
"floating constant exceeds range of 'long double'".  Avoid this by
referring to half the value of LDBL_MAX instead.

Now when pidfile_remove() uses unlinkat(2) to remove the pidfile
it is safe to use this function in capability mode.

The fix involves a change over r254091 and now the behavior matches the

b002bfbade Support for v1.10 (latest) of RISC-V privilege specification.
New version is not compatible on supervisor mode with v1.9.1
(previous version).

Highlights:
    o BBL (Berkeley Boot Loader) provides no initial page tables
      anymore allowing us to choose VM, to build page tables manually
      and enable MMU in S-mode.
    o SBI interface changed.
    o GENERIC kernel.
      FDT is now chosen standard for RISC-V hardware description.
      DTB is now provided by Spike (golden model simulator). This
      allows us to introduce GENERIC kernel. However, description
      for console and timer devices is not provided in DTB, so move
      these devices temporary to nexus bus.
    o Supervisor can't access userspace by default. Solution is to
      set SUM (permit Supervisor User Memory access) bit in sstatus
      register.
    o Compressed extension is now turned on by default.
    o External GCC 7.1 compiler used.
    o _gp renamed to __global_pointer$
    o Compiler -march= string is now in use allowing us to choose
      required extensions (compressed, FPU, atomic, etc).

39ef9da694 Pick 'Remove external linkage for spin_adaptive' from upstream jemalloc
Apply the changes from upstream jemalloc 048c6679.  This is actually not
quite a cherry pick due to makefile difference and because FreeBSD does
not carry the msvc project files which were also modified in that

db45713071 libusb(3): Expose device caps as libusb_bos_descriptor::dev_capability
Some libusb consumers in Linux-land (in this case, libusb4java) expect a
dev_capability member that they can use to enumerate the device
capabilities.

No particular layout is expected of this, just that it can be traversed
using the bLength member until bNumDeviceCapabilities are read and that the
consumer may then use one of the libusb_get_*_descriptor methods to extract
specific (usb 2.0 vs. ss) capability information.

a067da9017 regex(3): Refactor fast/slow stepping bits in the matching engine
Adding features for matching is fairly straightforward, but this requires
some duplication because of this fast/slow setup. They can be fairly

39d016e70f regex(3): Handle invalid {} constructs consistently and adjust tests
Currently, regex(3) exhibits the following wrong behavior as demonstrated
with sed:

 - echo "a{1,2,3}b" | sed -r "s/{/_/"     (1)
 - echo "a{1,2,3}b" | sed "s/\}/_/"       (2)
 - echo "a{1,2,3}b" | sed -r "s/{}/_/"    (3)

Cases (1) and (3) should throw errors but they actually succeed, and (2)
throws an error when it should match the literal '}'. The correct behavior
was decided by comparing to the behavior with the equivalent BRE (1)(3) or
ERE (2) and consulting POSIX, along with some reasonable evaluation.

Tests were also adjusted/added accordingly.

3364e8aea9 o Replace __riscv__ with __riscv

RISC-V is extensible ISA and the idea here is to have built-in define
per each extension, so together with __riscv we will have some subset
of these as well (depending on -march string passed to compiler):

__riscv_compressed
__riscv_atomic
__riscv_mul
__riscv_div
__riscv_muldiv
__riscv_fdiv
__riscv_fsqrt
