[ Upstream commit a222061b85234d8a44486a46bd4df7e2cda52385 ]
__uint128_t crops up in a few files that export symbols to modules, so teach genksyms about it and the other GCC built-in 128-bit integer types so that we don't end up skipping the CRC generation for some symbols due to the parser failing to spot them:
| WARNING: EXPORT symbol "kernel_neon_begin" [vmlinux] version | generation failed, symbol will not be versioned. | ld: arch/arm64/kernel/fpsimd.o: relocation R_AARCH64_ABS32 against | `__crc_kernel_neon_begin' can not be used when making a shared | object | ld: arch/arm64/kernel/fpsimd.o:(.data+0x0): dangerous relocation: | unsupported relocation
