Bug#863682: superseeding with new version
retitle 863682 jessie-pu: package intel-microcode/3.20170707.1~deb8u1
thanks
Intel released the fixes for Kaby Lake as well, so I am updating this
s-p-u bug for the newer version of the intel-microcode package.
Attached are the new diffs and diffstats. The reasoning for the stable
update is still the same, so I will quote it below.
Thank you!
For the record, this is related to:

As usual, I have removed the noise caused by the binary blob changes
from upstream from the debdiff output for clarity. The abridged debdiff
is attached.

Other than the microcode blob, the changes are only to documentation and
the changelogs.
Please note that the new upstream "releasenote" file is not going to be
shipped in the binary packages, since it has way too much incorrect
information. It is present only in the source package.
Thank you!

+-- Microcode update instructions --
+This package contains Intel microcode files in two formats:
+* microcode.dat
+* intel-ucode directory
+
+microcode.dat is in a traditional text format. It is still used in some
+Linux distributions. It can be updated to the system through the old microcode
+update interface which is avaialble in the kernel with
+CONFIG_MICROCODE_OLD_INTERFACE=y.
+
+To update the microcode.dat to the system, one need:
+1. Ensure the existence of /dev/cpu/microcode
+2. Write microcode.dat to the file, e.g.
+ dd if=microcode.dat of=/dev/cpu/microcode bs=1M
+
+intel-ucode dirctory contains binary microcode files named in
+family-model-stepping pattern. The file is supported in most modern Linux
+distributions. It's generally located in the /lib/firmware directory,
+and can be updated throught the microcode reload interface.
+
+To update the intel-ucode package to the system, one need:
+1. Ensure the existence of /sys/devices/system/cpu/microcode/reload
+2. Copy intel-ucode directory to /lib/firmware, overwrite the files in
+/lib/firmware/intel-ucode/
+3. Write the reload interface to 1 to reload the microcode files, e.g.
+ echo 1 > /sys/devices/system/cpu/microcode/reload
