isfinite(x) error

Add missing STM32_BKP_BASE

Added missing ARCH_HAVE_RESET for F7

SMP:  Fix timer related issues:  Round robin and sporadic scheduling were only being performed for tasks running on the CPU that processes the system timer interrupt.  Similary, CPU load measurements were only be processed for running on the CPU that receives the sampling interrupt.

Shared Libraries:  In the FLAT build mode, kernel modules may be used to provide minimal shared library functionality.

Fix a compile error: in sched_cpuload.c:Line136, the variables ts and secs are not defined if CONFIG_CPULOAD_ONESHOT_ENTROPY = 0. However, these variables are used regardless of CONFIG_CPULOAD_ONESHOT_ENTROPY at lines~180:onwards.

ARM memcpy():  Use DWord vs. HWord offset.  ARM 32-bit instructions must be aligned to DWord boundaries and this gives us more range in the jump tables.

Adding missing CONFIG_ prefix
