- Simplification and distangling of the MSI related functionality - Let IO/APIC construct the RTE entries from an MSI message instead of having IO/APIC specific code in the interrupt remapping drivers - Make the retrieval of the parent interrupt domain (vector or remap unit) less hardcoded and use the relevant irqdomain callbacks for selection. - Allow the handling of more than 255 CPUs without a virtualized IOMMU when the hypervisor supports it. This has made been possible by the above modifications and also simplifies the existing workaround in the HyperV specific virtual IOMMU. - Cleanup of the historical timer_works() irq flags related inconsistencies. -----BEGIN PGP SIGNATURE----- iQJHBAABCgAxFiEEQp8+kY+LLUocC4bMphj1TA10mKEFAl/Xxd8THHRnbHhAbGlu dXRyb25peC5kZQAKCRCmGPVMDXSYoYpOD/9C5TppNlPMUyx2SflH6bxt37pJEpln +hYTKsk+jSThntr5mfj+GifGvgmHOVBTGnlDUnUnrpN7TQmLFBzwTOtnBLW53AO2 16/u0+Xci4LNCtEkaymf0Rq4MfsfriXHPJr0A/CnZ0tpHSf5QKHAiitSiGujdMlb gbq43+zXd+jNkH7vkOLPX/7dZVI1hNASQEevJu2tRR4xYTuXFdBxvLgYkHtYKKrK R1sbs6nI6yIzye2u4m4xGu29SxgUft+zdUf+UehJKM3yFmf51d9qpkX+kLaTWuaL VPsMItbn0kdvxwXQWO6DYnIAAnVKCklyHQJTZCoNq9Fe91OoByak1CEVspSOa1av JmycNSch4IYWasR4vVCB1gbb+V9SejcKu5SV3CDrEDqwkOIpfiqpriUXSCJTLlFd QOEDOLuuk/79Qs//J/tb/nJ4IuKv8WPudDfIlMro8wUsAr67DjD4mnXprZ+svwWx Ct/0/Memk+BSa0cw6pvg24BUZGN6zrufkBu2HKT9GOXRUdNkdLkiPhT8mK4T/O0l f90QCLjPSOJ/K/pLEWdUHEPmgC5Q9RsXOmwVGqX+RbjfP7mYTJXlmWnBb+cFNch0 xFIH3SxVGylxxT06NX3SkvinrHj10CoAlmneefBlLtx6dF+2P84DAMZSF0OFToVI c2KMg5zoesI4bg== =8Gfs -----END PGP SIGNATURE----- Merge tag 'x86-apic-2020-12-14' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull x86 apic updates from Thomas Gleixner: "Yet another large set of x86 interrupt management updates: - Simplification and distangling of the MSI related functionality - Let IO/APIC construct the RTE entries from an MSI message instead of having IO/APIC specific code in the interrupt remapping drivers - Make the retrieval of the parent interrupt domain (vector or remap unit) less hardcoded and use the relevant irqdomain callbacks for selection. - Allow the handling of more than 255 CPUs without a virtualized IOMMU when the hypervisor supports it.
