Pull more RISC-V updates from Paul Walmsley:
 "Some additional RISC-V updates.

  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"
