  riscv: set the permission of vdso_data to read-only (2020-06-10 19:47:35 -0700)

----------------------------------------------------------------
RISC-V Patches for the 5.8 Merge Window, Part 2

* Select statements are now sorted alphanumerically.
* Our first-level interrupts are now handled via a full irqchip driver.
* CPU hotplug is fixed.
* Our vDSO calls now use the common vDSO infrastructure.

----------------------------------------------------------------
Anup Patel (7):
      RISC-V: self-contained IPI handling routine
      RISC-V: Rename and move plic_find_hart_id() to arch directory
      irqchip: RISC-V per-HART local interrupt controller driver
      clocksource/drivers/timer-riscv: Use per-CPU timer interrupt
      RISC-V: Remove do_IRQ() function
      RISC-V: Force select RISCV_INTC for CONFIG_RISCV
      RISC-V: Don't mark init section as non-executable
