Big, very risky change: Remove all occurrences of up_maskack_irq() that disable and enable interrupts with up_ack_irq() that only acknowledges the interrupts. This is only used in interrupt decoding logic. Also remove the logic that unconditionally re-enables interrupts with the interrupt exits. This interferes with the drivers ability to control the interrupt state. This is a necessary, sweeping, global change and unfortunately impossible to test.

ARMv7-A: Modify up_fullcontextrestore() for CONFIG_BUILD_KERNEL. It changed CPSR while in kernel. That will crash is the new CPSR is user mode while executing in kernel space. Fixed by adding a SYS_context_restore system call. There is an alternative, simpler modification to up_fullcontextrestore() that could have been done: It might have been possible to use the SPSR instead of the CPRSR and then do an exception return from up_fullcontextrestore(). That would be more efficient, but I never tried it.
