Pull x86 apic updates from Thomas Gleixner: - Cleanup the apic IPI implementation by removing duplicated code and consolidating the functions into the APIC core. - Implement a safe variant of the IPI broadcast mode. Contrary to earlier attempts this uses the core tracking of which CPUs have been brought online at least once so that a broadcast does not end up in some dead end in BIOS/SMM code when the CPU is still waiting for init. Once all CPUs have been brought up once, IPI broadcasting is enabled. Before that regular one by one IPIs are issued. - Drop the paravirt CR8 related functions as they have no user anymore - Initialize the APIC TPR to block interrupt 16-31 as they are reserved for CPU exceptions and should never be raised by any well behaving device. - Emit a warning when vector space exhaustion breaks the admin set affinity of an interrupt. - Make sure to use the NMI fallback when shutdown via reboot vector IPI fails. The original code had conditions which prevent the code path to be reached. - Annotate various APIC config variables as RO after init. [ The ipi broadcase change came in earlier through the cpu hotplug branch, but I left the explanation in the commit message since it was shared between the two different branches - Linus ] * 'x86-apic-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (28 commits) x86/apic/vector: Warn when vector space exhaustion breaks affinity x86/apic: Annotate global config variables as "read-only after init" x86/apic/x2apic: Implement IPI shorthands support x86/apic/flat64: Remove the IPI shorthand decision logic x86/apic: Share common IPI helpers x86/apic: Remove the shorthand decision logic x86/smp: Enhance native_send_call_func_ipi() x86/smp: Move smp_function_call implementations into IPI code x86/apic: Provide and use helper for send_IPI_allbutself() x86/apic: Add static key to Control IPI shorthands x86/apic: Move no_ipi_broadcast() out of 32bit x86/apic: Add NMI_VECTOR wait to IPI shorthand x86/apic: Remove dest argument from __default_send_IPI_shortcut() x86/hotplug: Silence APIC and NMI when CPU is dead x86/cpu: Move arch_smt_update() to a neutral place x86/apic/uv: Make x2apic_extra_bits static x86/apic: Consolidate the apic local headers x86/apic: Move apic_flat_64 header into apic directory x86/apic: Move ipi header into apic directory x86/apic: Cleanup the include maze ... |
