Subject: target/riscv: make CPUCFG() macro public
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=238fd586e0bc06d104d2d095170945b97ea56e19;p=qemu.git

target/riscv: make CPUCFG() macro public

The RISC-V KVM driver uses a CPUCFG() macro that calculates the offset
of a certain field in the struct RISCVCPUConfig. We're going to use this
macro in target/riscv/cpu.c as well in the next patches. Make it public.

Rename it to CPU_CFG_OFFSET() for more clarity while we're at it.
