21389c0613 score: Make EDF the default SMP scheduler 
The EDF SMP scheduler supports simple thread processor affinities
(see #3059) with a small run-time overhead. The current default SMP
scheduler lacks support for thread processor affinities at all. The EDF
SMP scheduler offers a good feature set for most applications. So, use
it by default. Run-time libraries like libgomp, MTAPI, work stealing
schedulers, language interpreters (e.g. Erlang virtual machine),
maintainence of per-processor data (e.g. Universal Memory Allocator
(UMA)), etc. use a one-to-one thread processor affinity for example.

Update #3063.

16347a6b39 score: Fix default set affinity 
The set of online processors must be a subset of the thread processor
affinity for the schedulers without arbitrary processor affinity support
to avoid problems in case of processor addition and removal.

_Processor_mask_To_uint32_t() to enable its use in device specific
routines, e.g. interrupt affinity register in an interrupt controller.

3e7827434d arm: Fix ARMv7-M interrupt processing 
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() did not check that a thread dispatch is
allowed.  Move this test from _ARMV7M_Interrupt_service_leave() to
_ARMV7M_Pendable_service_call().

Update #3060.
