Hi all,

Should we support intel-microcode package.

See tracker.debian.org/intel-microcode . It is a way to update Processor 
microcode firmware for Intel CPUs

 From today's changelog -

intel-microcode (3.20151106.1) unstable; urgency=medium

   * New upstream microcode data file 20151106
     + New Microcodes:
       sig 0x000306f4, pf mask 0x80, 2015-07-17, rev 0x0009, size 14336
       sig 0x00040671, pf mask 0x22, 2015-08-03, rev 0x0013, size 11264
     + Updated Microcodes:
       sig 0x000306c3, pf mask 0x32, 2015-08-13, rev 0x001e, size 21504
       sig 0x000306d4, pf mask 0xc0, 2015-09-11, rev 0x0022, size 16384
       sig 0x000306f2, pf mask 0x6f, 2015-08-10, rev 0x0036, size 30720
       sig 0x00040651, pf mask 0x72, 2015-08-13, rev 0x001d, size 20480
     * This massive Haswell + Broadwell (and related Xeons) update fixes
       several critical errata, including the high-hitting BDD86/BDM101/
       HSM153(?) which triggers an MCE and locks the processor core
       (LP: #1509764)
     * Might fix critical errata BDD51, BDM53 (TSX-related)
   * source: remove superseded upstream data file: 20150121
   * Add support for supplementary microcode bundles:
     + README.source: update and mention supplementary microcode
     + Makefile: support supplementary microcode
       Add support for supplementary microcode bundles, which (unlike .fw
       microcode override files) can be superseded by a higher revision
       microcode from the latest regular microcode bundle.  Also, fix the
       "oldies" target to have its own exclude filter (IUC_OLDIES_EXCLUDE)
     * Add support for x32 arch:
     + README.source: mention x32
     + control,rules: enable building on x32 arch (Closes: #777356)
   * ucode-blacklist: add Broadwell and Haswell-E signatures
     Add a missing signature for Haswell Refresh (Haswell-E) to the "must
     be updated only by the early microcode update driver" list.  There
     is at least one report of one of the Broadwell microcode updates
     disabling TSX-NI, so add them as well just in case

The controversial part is because the firmware packages are just 
blackboxes you actually do not know what you are installing, is it just 
correcting processor behaviour or also installing a back-door for the NSA.
