  riscv: Avoid interrupts being erroneously enabled in handle_exception() (2019-09-20 08:42:34 -0700)

----------------------------------------------------------------
RISC-V additional updates for v5.4-rc1

Some additional RISC-V updates for v5.4-rc1.  This includes one
significant fix:

- Prevent interrupts from being unconditionally re-enabled during
  exception handling if they were disabled in the context in which the
  exception occurred

Also a few other fixes:

- Fix a build error when sparse memory support is manually enabled

- Prevent CPUs beyond CONFIG_NR_CPUS from being enabled in early boot

And a few minor improvements:

- DT improvements: in the FU540 SoC DT files, improve U-Boot
  compatibility by adding an "ethernet0" alias, drop an unnecessary
  property from the DT files, and add support for the PWM device

- KVM preparation: add a KVM-related macro for future RISC-V KVM
  support, and export some symbols required to build KVM support as
  modules

- defconfig additions: build more drivers by default for QEMU
  configurations
