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

- defconfig additions: build more drivers by default for QEMU

RISC-V: Enable VIRTIO drivers in RV64 and RV32 defconfig
KVM: RISC-V: Add KVM_REG_RISCV for ONE_REG interface
