The existing upstream kernel doesn't boot for non-smp
configuration. This patch series address various issues
with non-smp configurations.

Tested on QEMU and HiFive Unleashed board.

Changes from v1->v2

1. Move the cpuid to hartd id map to smp.c from setup.c
2. Split 3rd patch into several small patches based on
logical grouping.
3. Added a new patch that fixes an issue in hwcap query.
4. Changed the title of the patch series.

Atish Patra (8):
RISC-V: Do not wait indefinitely in __cpu_up
RISC-V: Move cpuid to hartid mapping to SMP.
RISC-V: Remove NR_CPUs check during hartid search from DT
RISC-V: Allow hartid-to-cpuid function to fail.
RISC-V: Compare cpuid with NR_CPUS before mapping.
RISC-V: Add required checks during clock source init
RISC-V: Check and continue in case of an invalid cpuid.
RISC-V: Assign hwcap only according to current cpu.
