  "message": "arch: arm64: mmu: keep page table diagnostics printable before the MMU\n\nThe page table helpers run before the MMU is enabled, while the tables\nare being built, and again at run time from arch_mem_map(). In the first\nphase neither the logging subsystem nor printk()\u0027s spinlock is usable,\nbecause the atomics under them need the shareable memory attributes the\nMMU provides, so a diagnostic there faults instead of printing. That is\nwhere this started: a page table failure during early bring-up produced\nsilence.\n\nTest the MMU and pick the path accordingly. mmu_is_enabled() reads\nSCTLR_EL1 and tests M, which compiles to an mrs and a tbz. With the MMU\non the messages take the ordinary LOG_*() path, keeping level filtering,\ntimestamps, the backends and serialized output. With it off they degrade\nto an unlocked printk() to the character hook.\n\nGating on the log core\u0027s own Z_LOG_CONST_LEVEL_CHECK() keeps the\nbuild-time level filtering: a filtered-out level drops both branches and\nits arguments. Verified on qemu_cortex_a53, where the INF format string\nis in the binary with CONFIG_KERNEL_LOG_LEVEL_INF and gone with\nCONFIG_KERNEL_LOG_LEVEL_ERR.\n\nErrors here precede a k_panic() and must appear with logging compiled out\ntoo, so they keep this file\u0027s existing printk() fallback.\n\nSigned-off-by: Nicolas Pitre \u003cnpitre@baylibre.com\u003e\n",
