Here's a lightly tested backport of the Spectre v1 swapgs mitigation, for 4.9.
Hm, you backported 64dbc122b20f ("x86/entry/64: Use JMP instead of JMPQ") which is not in 4.14.y,
For 4.14, it was apparently folded into the backport of "x86/speculation: Prepare entry code for Spectre v1 swapgs mitigations".
yet you did not backport 4c92057661a3 ("Documentation: Add swapgs description to the Spectre v1 documentation") which should go to this kernel too, right?
That touches a file that doesn't exist. We'd first need a backport of commit 6e88559470f5 "Documentation: Add section about CPU vulnerabilities for Spectre".
