Subject: [PATCH 0/9] TAA v2
Hi,
lemme send the pile out one more time before I leave for OSS EU in Lyon.
Patch 6 is still there until Paolo and Tony have figured out what should
happen with guests.
changelog:
==========
v1:
here's the pile I've picked up. I've incorporated as much of the
feedback as possible, scream loudly if something's missing. First
testing looks good.
We'll cast them in stone in the coming days because distros and stable
have to start backporting soon. All fixes will go ontop, as in previous
occasions.
Michal Hocko (1):
x86/tsx: Add config options to set tsx=on|off|auto
Pawan Gupta (8):
x86/msr: Add the IA32_TSX_CTRL MSR
x86/cpu: Add a helper function x86_read_arch_cap_msr()
x86/cpu: Add a "tsx=" cmdline option with TSX disabled by default
x86/speculation/taa: Add mitigation for TSX Async Abort
x86/speculation/taa: Add sysfs reporting for TSX Async Abort
kvm/x86: Export MDS_NO=0 to guests when TSX is enabled
x86/tsx: Add "auto" option to the tsx= cmdline parameter
x86/speculation/taa: Add documentation for TSX Async Abort
