0bfad43298 Include ABI note tag in shared libraries.
Split the ELF feature note into a separate file that is linked into
*crt1.o the same as crtbrand.S was before.  crtbrand.o is now linked
into crti.o on all platforms in addition to *crt1.o.

7a61fe3a30 Don't imply that all action values can be OR'd.
This is neither POSIX compliant nor what the implementation does.
This could be allowed by changing the value of TCSAFLUSH from 2 to 3,

a9ea004745 Avoid rebuilding libpmc in every incremental rebuild
Generate libpmc_events.c in a temporary file first and only overwrite it
if the files are actually different.

f4f16af1d3 Avoid copying out kernel pointers from msgctl(IPC_STAT).
While this behaviour is harmless, it is really just an artifact of the
fact that the msgctl(2) implementation uses a user-visible structure as
part of the internal implementation, so it is not deliberate and these
pointers are not useful to userspace.  Thus, NULL them out before
copying out, and remove references to them from the manual page.

bbfbc439f2 Fix printf(3) output of long doubles on RISC-V
When the RISC-V port was initially committed to FreeBSD, GCC would
generate 64-bit long doubles, and the definitions in _fpmath.h reflected
that. This was changed to 128-bit in GCC later that year [1], but the
definitions were never updated, despite the documented workaround. This
causes printf(3) and friends to interpret only the low 64-bits of a long
double in ldtoa, thereby printing incorrect values.

Update the definitions now that both clang and GCC generate 128-bit long
doubles.

f045cfb816 Chroot actually appeared in 7th Edition Unix.
Chroot appeared during the development of 7th edition Unix. The FreeBSD jail
documents, incorrectly, that Bill Joy added this to 4.2BSD on 18 March
1982. That was when Bill Joy converted from a statically coded system call glue
to dynamically generated assembler. Chroot was present in 32V, 3BSD, 4.0BSD, 4.1BSD
and 4.1cBSD well in advance of this. Kirk McKusick agrees with this analysis.

See also:
	V7: https://minnie.tuhs.org/cgi-bin/utree.pl?file=V7/usr/src/libc/sys/chroot.s
	32V: https://minnie.tuhs.org/cgi-bin/utree.pl?file=32V/usr/src/libc/sys/chroot.s

	4BSD: https://minnie.tuhs.org/cgi-bin/utree.pl?file=4BSD/usr/src/libc/sys/chroot.s
	4.1cBSD: https://minnie.tuhs.org/cgi-bin/utree.pl?file=4.1cBSD/usr/src/libc/sys/chroot.s

The 6th and earlier editions do not have this system call, nor do they have
anything named chroot in the trees available from TUHS.

2d143336de Enable long double tests on RISC-V
Some of the NetBSD contributed tests are gated behind the
__HAVE_LONG_DOUBLE flag. This flag seems to be defined only for
platforms whose long double is larger than their double. I could not
find this explicitly documented anywhere, but it is implied by the
definitions in NetBSD's sys/arch/${arch}/include/math.h headers, and the
following assertion from the UBSAN code:

  #ifdef __HAVE_LONG_DOUBLE
      long double LD;
      ASSERT(sizeof(LD) > sizeof(uint64_t));
  #endif

RISC-V has 128-bit long doubles, so enable the tests on this platform,
and update the comments to better explain the purpose of this flag.

assumed a "timestamp" field exists when it doesn't and an exception is thrown.

Add a space to the search string so we match exactly "timestamp" rather than
anything with that as a suffix.
