Palmer Dabbelt	8606544890	RISC-V: Don't include irq-riscv-intc.h ... This file has never existed in the upstream kernel, but it's guarded by an #ifdef that's also never existed in the upstream kernel. As a part of our interrupt controller refactoring this header is no longer necessary, but this reference managed to sneak in anyway.

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.

Palmer Dabbelt	76d2a0493a	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. Signed-off-by: Palmer Dabbelt <palmer@dabbelt.com>	2017-09-26 15:26:44 -07:00
