  "message": "arm: use BASEPRI_MAX instead of BASEPRI to mask interrupts\n\nWhen locking interrupt in a critical session, it is\nsafer to do MSR BASEPRI_MAX instead of BASEPRI. The\nrationale is that when writing to BASEPRI_MAX, the\nwriting is conditional, and is only applied if the\nchange is to a higher priority level. This commit\nreplaces BASEPRI with BASEPRI_MAX in operations that\naim to lock some specific interrupts:\n- irq_lock()\n- masking out PendSV\nSo, for example, it is not possible to actually\nunmask any interrupts by doing an irq_lock operation.\nThe commit does not introduce behavioral changes.\nHowever, it makes irq_lock() more robust against\nfuture changes to the IRQ locking mechanism.\n\nSigned-off-by: Ioannis Glaropoulos \u003cIoannis.Glaropoulos@nordicsemi.no\u003e\n",
