Palmer Dabbelt	cc6c98485f	RISC-V: Move to the new GENERIC_IRQ_MULTI_HANDLER handler The existing mechanism for handling IRQs on RISC-V is pretty ugly: the irq entry code selects the handler via Kconfig dependencies. Use the new generic IRQ handling infastructure, which allows boot time registration of the low level entry handler. This does add an additional load to the interrupt latency, but there's a lot of tuning left to be done there on RISC-V so it's OK for now.

RISC-V: Move to the new GENERIC_IRQ_MULTI_HANDLER handler

The existing mechanism for handling IRQs on RISC-V is pretty ugly: the irq
entry code selects the handler via Kconfig dependencies.

Use the new generic IRQ handling infastructure, which allows boot time
registration of the low level entry handler.

This does add an additional load to the interrupt latency, but there's a
lot of tuning left to be done there on RISC-V so it's OK for now.

RISC-V: Init and Halt Code

This contains the various __init C functions, the initial assembly
kernel entry point, and the code to reset the system.  When a file was
init-related this patch contains the entire file.
