  [ Balint Reczey ]
  * XFAIL tst-sigcontext-get_pc on ppc64el (LP: #1907298)
  * Merge 2.31-9 changes from Debian unstable:
    - Build memusage and memusagestat in the libc pass and ship them into
      libc-devtools. Move mtrace, sotruss and sprof into that package.
      Closes: #91815.
    - debian/sysdeps/arm64.mk: enable static PIE support on arm64.
      Closes: #973430.
    - debian/debhelper.in/*.lintian-overrides: update for recent lintian
      versions.
    - other changes less interesting for Ubuntu users
  * Support disabling hwcaps on amd64 and arm64, too
  * Optimize checking /etc/ld.so.nohwcap
  * New upstream release 2.33
    - security fixes:
      - CVE-2021-3326: An assertion failure during conversion from the
        ISO-20220-JP-3 character set using the iconv function has been fixed.
        This assertion was triggered by certain valid inputs in which the
        converted output contains a combined sequence of two wide characters
        crossing a buffer boundary.  Reported by Tavis Ormandy.
      - CVE-2020-29562: An assertion failure has been fixed in the iconv
        function when invoked with UCS4 input containing an invalid character.
      - CVE-2019-25013: A buffer overflow has been fixed in the iconv function
        when invoked with EUC-KR input containing invalid multibyte input
        sequences.
  * Refresh patches
  * debian/symbols.wildcards: Update for 2.33
  * Don't ship /etc/default/nss.
    It set only ADJUNCT_AS_SHADOW=TRUE to change NSS module behaviour to be
    more secure, but upstream disagrees that the default (FALSE) value poses
    a security problem since the data leaked by NSS is made available by
    other tools as well.
    See: https://sourceware.org/bugzilla/show_bug.cgi?id=11134
  * debian/debhelper.in/libc-bin.install: Keep installing zdump
    adjust .install to upstream's changes
  * XFAIL rounding test failures on armhf (and armel)
  * XFAIL elf/tst-cpu-features-cpuinfo on amd64 and i386
  * XFAIL nptl/tst-cancel28 on i386
  * debian/copyright: Add GFDL for the manual sources.
    Override the Lintian error about GFDL, Ubuntu ships the documentation
    in main already.
