Pull RISC-V fixes from Palmer Dabbelt:

 - Avoid accessing the early boot ACPI tables via unsafe memory
   attributes, which can result in incorrect ACPI table data appearing.
   This can cause all sorts of bad behavior.

 - Avoid compiler-inserted library calls in the VDSO.

 - GCC+Rust builds have been disabled, to avoid issues related to ISA
   string mismatched between the GCC and LLVM Rust implementations.

 - The NX flag is now set in the EFI PE/COFF headers, which is necessary
   for some distro GRUB versions to boot images.

 - A fix to avoid leaking DT node reference counts on ACPI systems
   during cache info parsing.

 - CPU numbers are now printed as unsigned values during hotplug.

 - A pair of build fixes for usused macros, which can trigger warnings
   on some configurations.
