- Correct a few problems in the x86 and the generic membarrier implementation. Small corrections for assumptions about visibility which have turned out not to be true. - Make the PAT bits for memory encryption correct vs. 4K and 2M/1G page table entries as they are at a different location. - Fix a concurrency issue in the the local bandwidth readout of resource control leading to incorrect values - Fix the ordering of allocating a vector for an interrupt. The order missed to respect the provided cpumask when the first attempt of allocating node local in the mask fails. It then tries the node instead of trying the full provided mask first. This leads to erroneous error messages and breaking the (user) supplied affinity request. Reorder it. - Make the INT3 padding detection in optprobe work correctly. -----BEGIN PGP SIGNATURE----- iQJHBAABCgAxFiEEQp8+kY+LLUocC4bMphj1TA10mKEFAl/WOw0THHRnbHhAbGlu dXRyb25peC5kZQAKCRCmGPVMDXSYodUhEACW02Al+mlpZjOhzIGwNUALGX7YGEOi wJoiIDTV2vOtKhcJ/AOVn05CznoWXa6PN1+7pm0nR2M1XaiXZ3B6HMjy1+0rpSqK 5dCCEqr+QowwMRsKd4hnuJowR/7Og66FiYIcknDJg/1egg+RXy7yKds577W6/KW0 2VV/x35xDywERiQ28qIftQ4L7NREyiioomN/GFpeoQf8tQF06Rb4t12T5pdA6D8S /C1wj0IKVRMJo/7HbB/X6skxPOK0PWAEBpaT0+Q66VKSNnFVN5ap+rGTKdUoTmuM NdxHOukpHyFCQtbRPOjRUeeSZJLKSX5oXsBO1GUvyyxcT2XNlTOdNamYLWyO+RfV uP97qhzYDKL+cgDkwypJ0WOzOb9EIXOh4P9BTnJFBGhc4EQwen3cpb3CyWWftjnv /obXiRDnAOE6P6H2AGiwrK3Pny+SvgrFYKMe+iy+ntToz1yrDh7ZrZ0DQKVoFWEr n3qUnlPZmVvRzHIRVYoK69nS/UgmNN0LssavzRBzab3BcK93f23QkW86P42kNCLa 9kL+ZgGwlpqUZZR/p3pHq9Mv2ZXGEdUYY99h2vy1fgMwOw/RQZnPDAj/131UXlsU 4DL0mAlTK1/0/81H6/V1GDBkMkO+hN4x6Y3asi7bPHEKEzlLe+P1tUt3YELd3CEC dc8ebICG1InXsw== =t31y -----END PGP SIGNATURE----- Merge tag 'x86-urgent-2020-12-13' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull x86 fixes from Thomas Gleixner: "A set of x86 and membarrier fixes: - Correct a few problems in the x86 and the generic membarrier implementation.
