That makes all related topology # functions work correctly and does not affect the actual APIC driver # code at all. # # - Don't evaluate logical IDs during early boot as the local APIC IDs # are not yet enumerated and the invoked function returns an error # code. Nothing requires the logical IDs before the final CPUID # enumeration takes place, which happens after the enumeration. # # - Cure the fallout of the per CPU rework on UP which misplaced the # copying of boot_cpu_data to per CPU data so that the final update to # boot_cpu_data got lost which caused inconsistent state and boot # crashes. # # - Use copy_from_kernel_nofault() in the kprobes setup as there is no # guarantee that the address can be safely accessed. # # - Reorder struct members in struct saved_context to work around another # kmemleak false positive # # - Remove the buggy code which tries to update the E820 kexec table for # setup_data as that is never passed to the kexec kernel. # # - Update the resource control documentation to use the proper units. # # - Fix a Kconfig warning observed with tinyconfig # # * tag 'x86-urgent-2024-03-24' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: #
