6.18-stable review patch. If anyone has any objections, please let me know. ------------------ From: Zongmin Zhou commit edba6017c19f97ecc718fad6b50e0908392247ac upstream. BIT() is a kernel-internal macro that is not available to userspace, but the MIPS vendor extension uapi header uses it without defining or including it. Any userspace program that includes this header and uses RISCV_HWPROBE_VENDOR_EXT_XMIPSEXECTL fails to build. Use _BITULL(0) from linux/const.h instead, which keeps the value at 1, so there is no ABI change.
