# 
#     Merge tag 'riscv/for-v5.4-rc1-b' of git://git.kernel.org/pub/scm/linux/kernel/git/riscv/linux
#     
#     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"
