Continue Spectre v4 review:
* x86/speculation: Update Speculation Control microcode
blacklist
-> skip, we do not carry the blacklist
* x86/speculation: Correct Speculation Control
microcode blacklist again
-> skip, again firmware blacklist
* x86/speculation: Clean up various Spectre related
details
-> pick, adjusted to match intended goals (low risk
as this is only removing line breaks or updating
printks).
* x86/speculation: Add <asm/msr-index.h> dependency
-> skip, no change
* x86/spectre_v2: Don't check microcode versions when
running under hypervisors
-> skip, we do not check for bad microcode versions
* x86/speculation: Use IBRS if available before calling
into firmware
-> pick, adapted to current environment. We already
had alternative_msr_write() ported.

Title:
Xenial update to 4.4.144 stable release
Status in linux package in Ubuntu:
Invalid
Status in linux source package in Xenial:
In Progress
Bug description:
SRU Justification
Impact:
The upstream process for stable tree updates is quite similar
in scope to the Ubuntu SRU process, e.g., each patch has to
demonstrably fix a bug, and each patch is vetted by upstream
by originating either directly from a mainline/stable Linux tree or
a minimally backported form of that patch. The 4.4.144 upstream stable
patch set is now available. It should be included in the Ubuntu
kernel as well.
git://git.kernel.org/
TEST CASE: TBD
The following patches from the 4.4.144 stable release shall be
applied:
