This patch series address various issues with non-smp configurations. The patch series is based on 5.0-rc5. Tested on QEMU and HiFive Unleashed board using both OpenSBI & BBL. Changes from v2->v3 1. Fixed spurious white space. 2. Added lockdep for smpboot completion variable. 2. Added a sanity check for hwcap. 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. clocksource/drivers/riscv: Add required checks during clock source init irqchip/irq-sifive-plic:: Check and continue in case of an invalid cpuid. RISC-V: Assign hwcap only according to boot cpu. arch/riscv/include/asm/smp.h | 14 ++++++++--- arch/riscv/kernel/cpu.c | 4 --- arch/riscv/kernel/cpufeature.c | 52 +++++++++++++++++++++++++++------------ arch/riscv/kernel/setup.c | 9 ------- arch/riscv/kernel/smp.c | 10 +++++++- arch/riscv/kernel/smpboot.c | 20 ++++++++++++--- drivers/clocksource/timer-riscv.c | 23 ++++++++++++++--- drivers/irqchip/irq-sifive-plic.c | 5 ++++ 8 files changed, 98 insertions(+), 39 deletions(-) -- 2.7.4
