With UBSAN enabled, this leads to a crash during boot when\nis_midr_in_range_list() is inlined (which was more common prior to\nc8c2647e69be (\"arm64: Make \u00a0_midr_in_range_list() an exported\nfunction\")):\n\n |  Internal error: aarch64 BRK: 00000000f2000001 [#1] PREEMPT SMP\n |  pstate: 804000c5 (Nzcv daIF +PAN -UAO -TCO -DIT -SSBS BTYPE=--)\n |  pc : spectre_bhb_loop_affected+0x28/0x30\n |  lr : is_spectre_bhb_affected+0x170/0x190\n | [...]\n |  Call trace:\n |   spectre_bhb_loop_affected+0x28/0x30\n |   update_cpu_capabilities+0xc0/0x184\n |   init_cpu_features+0x188/0x1a4\n |   cpuinfo_store_boot_cpu+0x4c/0x60\n |   smp_prepare_boot_cpu+0x38/0x54\n |   start_kernel+0x8c/0x478\n |   __primary_switched+0xc8/0xd4\n |  Code: 6b09011f 54000061 52801080 d65f03c0 (d4200020)\n |  ---[ end trace 0000000000000000 ]---\n |  Kernel panic - not syncing: aarch64 BRK: Fatal exception\n\nAdd the missing sentinel entries.\n\ud83d\udccf Published: 2025-05-20T15:21:55.253Z\n\ud83d\udccf Modified: 2025-06-27T10:21:19.345Z\n\ud83d\udd17 References:\n1. https://git.kernel.org/stable/c/e68da90ac00d8b681561aeb8f5d6c47af3a04861\n2. https://git.kernel.org/stable/c/6266b3509b2c6ebf2f9daf2239ff8eb60c5f5bd3\n3. https://git.kernel.org/stable/c/446289b8b36b2ee98dabf6388acbddcc33ed41be\n4. https://git.kernel.org/stable/c/3821cae9bd5a99a42d3d0be1b58e41f072cd4c4c\n5. https://git.kernel.org/stable/c/090c8714efe1c3c470301cc2f794c1ee2a57746c\n6. https://git.kernel.org/stable/c/333579202f09e260e8116321df4c55f80a19b160\n7. https://git.kernel.org/stable/c/fee4d171451c1ad9e8aaf65fc0ab7d143a33bd72", "creation_timestamp": "2025-06-27T10:49:53.000000Z"}]}
