Christoph Hellwig	2f12dbf190	riscv: don't use the rdtime(h) pseudo-instructions ... If we just use the CSRs that these map to directly the code is simpler and doesn't require extra inline assembly code. Also fix up the top-level comment in timer-riscv.c to not talk about the cycle count or mention details of the clocksource interface, of which this file is just a consumer.

Palmer Dabbelt	6d60b6ee0c	RISC-V: Device, timer, IRQs, and the SBI ... This patch contains code that interfaces with devices that are mandated by the RISC-V supervisor specification and that don't have explicit drivers anywhere else in the tree. This includes the staticly defined interrupts, the CSR-mapped timer, and virtualized SBI devices. Signed-off-by: Palmer Dabbelt <palmer@dabbelt.com>	2017-09-26 15:26:47 -07:00
