Patch by Zan Dobersek <[email protected]> on 2021-07-22
Reviewed by Adrian Perez de Castro.
Detect when compiling for the RISC-V 64-bit architecture and define
the WTF_CPU_RISCV64 macro under that condition, enabling use of
CPU(RISCV64) build guards.
* wtf/PageBlock.h: Use 4 kB as the page size ceiling for CPU(RISCV64).
* wtf/PlatformCPU.h:
