Continue Spectre v4 review:
* x86/bugs: Provide boot parameters for the
spec_store_bypass_disable mitigation
-> skip, no change
* x86/bugs/intel: Set proper CPU features and setup RDS
-> skip, no change but note that we keep using
ibrs_inuse() instead of the feature bit.
* x86/bugs: Whitelist allowed SPEC_CTRL MSR values
-> skip, no change
* x86/bugs/AMD: Add support to disable RDS on Fam[15,
16, 17]h if requested
-> skip, no change
* x86/speculation: Create spec-ctrl.h to avoid include
hell
-> skip, no change
* prctl: Add speculation control prctls
-> skip, no change
* x86/process: Optimize TIF checks in __switch_to_xtra()
-> skip, no change
* x86/process: Correct and optimize TIF_BLOCKSTEP switch
-> pick, no change
* x86/process: Optimize TIF_NOTSC switch
-> pick, context
* x86/process: Allow runtime control of Speculative
Store Bypass
-> skip, no change
* x86/speculation: Add prctl for Speculative Store
Bypass mitigation
-> skip, no change
* nospec: Allow getting/setting on non-current task
-> skip, no change
* proc: Provide details on speculation flaw mitigations
-> skip, no change
* seccomp: Enable speculation flaw mitigations
-> skip, no change
* prctl: Add force disable speculation
-> skip, no change
* seccomp: Use PR_SPEC_FORCE_DISABLE
-> skip, no change
* seccomp: Add filter flag to opt-out of SSB mitigation
-> skip, no change
* seccomp: Move speculation migitation control to arch
code
-> skip, no change
* x86/speculation: Make "seccomp" the default mode for
Speculative Store Bypass
-> skip, no change
* x86/bugs: Rename _RDS to _SSBD
-> skip, no change
* proc: Use underscores for SSBD in 'status'
-> skip, no change
* Documentation/spec_ctrl: Do some minor cleanups
-> skip, no change
* x86/bugs: Fix __ssb_select_mitigation() return type
-> skip, no change
* x86/bugs: Make cpu_show_common() static
-> skip, no change
* x86/bugs: Fix the parameters alignment and missing
void
-> skip, no change
* x86/cpu: Make alternative_msr_write work for 32-bit
code
-> skip, no change
* x86/speculation: Use synthetic bits for
IBRS/IBPB/STIBP
-> skip, no change
* x86/cpufeatures: Disentangle MSR_SPEC_CTRL
enumeration from IBRS
-> skip, no change
* x86/cpufeatures: Disentangle SSBD enumeration
-> skip, no change
* x86/cpu/AMD: Fix erratum 1076 (CPB bit)
-> pick and revert previous version
The upstream commit does this by adding the
Zen specific init function.
* x86/cpufeatures: Add FEATURE_ZEN
-> pick, partial
The bit is already define in a previous patch.
Likely needs proper revert sequence later.
* x86/speculation: Handle HT correctly on AMD
-> skip, no change
* x86/bugs, KVM: Extend speculation control for
VIRT_SPEC_CTRL
-> skip, no change
* x86/speculation: Add virtualized speculative store
bypass disable support
-> skip, no change
* x86/speculation: Rework
speculative_store_bypass_update()
-> skip, no change
* x86/bugs: Unify x86_spec_ctrl_{set_guest,
restore_host}
-> skip, no change
* Expose x86_spec_ctrl_base directly
-> skip, no change
* x86/bugs: Remove x86_spec_ctrl_set()
-> skip, no change
* x86/bugs: Rework spec_ctrl base and mask logic
-> skip, no change
* x86/speculation, KVM: Implement support for
VIRT_SPEC_CTRL/LS_CFG
-> skip, no change
* x86/bugs: Rename SSBD_NO to SSB_NO
-> skip, no change
* x86/xen: Add call of speculative_store_bypass_ht_init()
to PV paths

re-read

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:
