The rc.initdiskless functionality is used by NanoBSD to allow configuration files to live on a separate configuration slice, which acts as NVRAM, whilst the system image is mounted read-only. Normally, if the remount command fails during boot, this is regarded as a fatal error. If /conf/T/M/remount_optional is present, this error is non-fatal. If the file is not present, the default behaviour is unchanged. This is very useful for people building live CD images using FreeBSD, where the NVRAM lives somewhere completely differently from the system image, and may be present on removable media which is not present during the initial boot.

Instead, detect the pipe and set up a special exec handler that indirects write() calls through stdout. This fixes the problem where ``set device "!ssh -e none host ppp -direct label"'' no longer works with an openssh-5.2 server side as that version of openssh ignores the USE_PIPES config setting and *always* uses pipes (rather than socketpair) for stdin/stdout channels.

Log:
  MFC 181019, 183474, 191277, and 191626:
  - Move the code for doing out-of-memory grass from vm_pageout_scan()
    into the separate function vm_pageout_oom(). Supply a parameter for
    vm_pageout_oom() describing a reason for the call.
  - Call vm_pageout_oom() from the swp_pager_meta_build() when swap zone
    is exhausted.
  - In both pageout oom handler and vm_daemon, acquire the reference to
    the vmspace of the examined process instead of directly accessing its
    vmspace, that may change. Also, as an optimization, check for P_INEXEC
    flag before examining the process.

  Fix a few issues with the lib32 dist so that it includes ldd32.
  - Use a better find invocation to purge empty directories from all the dist
    trees during a release build.  The previous version did not purge
    directories whose contents were all empty directories.
  - Explicitly blacklist a few files from the lib32 dist instead of using a
    whitelist.  A better longterm solution is to fix the few offenders to not
    install data files during a lib32 install.

New Revision: 196602
URL: http://svn.freebsd.org/changeset/base/196602

Log:
  MFC r196512:
  
    Fix handling of .note.ABI-tag section for GNU systems [1].
    Handle GNU/Linux according to LSB Core Specification 4.0,
    Chapter 11. Object Format, 11.8. ABI note tag.
  
    Also check the first word of desc, not only name, according to
    glibc abi-tags specification to distinguish between Linux and
    kFreeBSD.
  
    Add explicit handling for Debian GNU/kFreeBSD, which runs
    on our kernels as well [2].
  
    In {amd64,i386}/trap.c, when checking osrel of the current process,
    also check the ABI to not change the signal behaviour for Linux
    binary processes, now that we save an osrel version for all three
    from the lists above in struct proc [2] (slightly different to HEAD).
  
    These changes make it possible to run FreeBSD, Debian GNU/kFreeBSD
    and Linux binaries on the same machine again for at least i386 and
    amd64, and no longer break kFreeBSD which was detected as GNU(/Linux).
  
  PR:		kern/135468
  Submitted by:	dchagin [1] (initial patch)
  Suggested by:	kib [2]
  Tested by:	Petr Salinger (Petr.Salinger seznam.cz) for kFreeBSD

Log:
  MFC 196224:
  Adjust the handling of the local APIC PMC interrupt vector:
  - Provide lapic_disable_pmc(), lapic_enable_pmc(), and lapic_reenable_pmc()
    routines in the local APIC code that the hwpmc(4) driver can use to
    manage the local APIC PMC interrupt vector.
  - Do not enable the local APIC PMC interrupt vector by default when
    HWPMC_HOOKS is enabled.  Instead, the hwpmc(4) driver explicitly
    enables the interrupt when it is succesfully initialized and disables
    the interrupt when it is unloaded.  This avoids enabling the interrupt
    on unsupported CPUs which may result in spurious NMIs.

New Revision: 196646
URL: http://svn.freebsd.org/changeset/base/196646

Log:
  MFC 196478:
  Prior to the dire warning about values of network_interfaces other than
  AUTO the biggest mistake users made was leaving lo0 off the list. Since
  lo0 is effectively mandatory, check for it and add it to the list if
  it's not there.
  
  MFC 196523:
  Improve the case test to detect the presence of lo0 in the list of
  network_interfaces.
