#3060: ARMv7-M interrupt processing is broken
-----------------------------+-----------------------------
Reporter: Sebastian Huber | Owner: Sebastian Huber

-----------------------------+-----------------------------
Right after a "msr basepri_max, %[basepri]" instruction an interrupt
service may still take place (observed at least on Cortex-M7). However,
pendable service calls that are activated during this interrupt service
may be delayed until interrupts are enable again. The
_ARMV7M_Pendable_service_call() does currently not check that a thread
dispatch is allowed. Move this test from
_ARMV7M_Interrupt_service_leave() to _ARMV7M_Pendable_service_call().
