#     Merge branch 'l1tf-final' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
#     
#     Merge L1 Terminal Fault fixes from Thomas Gleixner:
#      "L1TF, aka L1 Terminal Fault, is yet another speculative hardware
#       engineering trainwreck. It's a hardware vulnerability which allows
#       unprivileged speculative access to data which is available in the
#       Level 1 Data Cache when the page table entry controlling the virtual
#       address, which is used for the access, has the Present bit cleared or
#       other reserved bits set.
#     
#       If an instruction accesses a virtual address for which the relevant
#       page table entry (PTE) has the Present bit cleared or other reserved
#       bits set, then speculative execution ignores the invalid PTE and loads
#       the referenced data if it is present in the Level 1 Data Cache, as if
#       the page referenced by the address bits in the PTE was still present
#       and accessible.
#     
#       While this is a purely speculative mechanism and the instruction will
#       raise a page fault when it is retired eventually, the pure act of
#       loading the data and making it available to other speculative
#       instructions opens up the opportunity for side channel attacks to
#       unprivileged malicious code, similar to the Meltdown attack.
#     
#       While Meltdown breaks the user space to kernel space protection, L1TF
#       allows to attack any physical memory address in the system and the
#       attack works across all protection domains. It allows an attack of SGX
#       and also works from inside virtual machines because the speculation
#       bypasses the extended page table (EPT) protection mechanism.
#     
#       The assoicated CVEs are: CVE-2018-3615, CVE-2018-3620, CVE-2018-3646
#     
#       The mitigations provided by this pull request include:
#     
#        - Host side protection by inverting the upper address bits of a non
#          present page table entry so the entry points to uncacheable memory.
#     
#        - Hypervisor protection by flushing L1 Data Cache on VMENTER.
#     
#        - SMT (HyperThreading) control knobs, which allow to 'turn off' SMT
#          by offlining the sibling CPU threads. The knobs are available on
#          the kernel command line and at runtime via sysfs
#     
#        - Control knobs for the hypervisor mitigation, related to L1D flush
#          and SMT control. The knobs are available on the kernel command line
#          and at runtime via sysfs
#     
#        - Extensive documentation about L1TF including various degrees of
#          mitigations.
#     
#       Thanks to all people who have contributed to this in various ways -
#       patches, review, testing, backporting - and the fruitful, sometimes
#       heated, but at the end constructive discussions.
#     
#       There is work in progress to provide other forms of mitigations, which
#       might be less horrible performance wise for a particular kind of
#       workloads, but this is not yet ready for consumption due to their
#       complexity and limitations"
