irqchip/sifive-plic: set max threshold for ignored handlers (2019-09-05 01:59:55 -0700)
----------------------------------------------------------------
RISC-V updates for v5.4-rc1
Add the following new features:
- Generic CPU topology description support for DT-based platforms,
including ARM64, ARM and RISC-V.
- Sparsemem support
- Perf callchain support
- SiFive PLIC irqchip modifications, in preparation for M-mode Linux
and clean up the code base:
- Clean up chip-specific register (CSR) manipulation code, IPIs, TLB
flushing, and the RISC-V CPU-local timer code
- Kbuild cleanup from one of the Kbuild maintainers
----------------------------------------------------------------
Atish Patra (4):
dt-binding: cpu-topology: Move cpu-map to a common binding.
cpu-topology: Move cpu topology code to common code.
arm: Use common cpu_topology structure and functions.
RISC-V: Parse cpu topology during boot.
Bin Meng (1):
riscv: Using CSR numbers to access CSRs
Christoph Hellwig (7):
riscv: refactor the IPI code
riscv: cleanup send_ipi_mask
riscv: optimize send_ipi_single
riscv: cleanup riscv_cpuid_to_hartid_mask
riscv: don't use the rdtime(h) pseudo-instructions
riscv: move the TLB flush logic out of line
irqchip/sifive-plic: set max threshold for ignored handlers
Logan Gunthorpe (1):
RISC-V: Implement sparsemem
Mao Han (3):
riscv: Add perf callchain support
riscv: Add support for perf registers sampling
