- # For the pre-R6 code in arch/mips/vdso/vdso.h for locating
- # the base address of VDSO, the linker will emit a R_MIPS_PC32
- # relocation in binutils > 2.25 but it will fail with older versions
- # because that relocation is not supported for that symbol. As a result
- # of which we are forced to disable the VDSO symbols when building
- # with < 2.25 binutils on pre-R6 kernels. For more references on why we
- # can't use other methods to get the base address of VDSO please refer to
- # the comments on that file.
- #
- # GCC (at least up to version 9.2) appears to emit function calls that make use
- # of the GOT when targeting microMIPS, which we can't use in the VDSO due to
- # the lack of relocations. As such, we disable the VDSO for microMIPS builds.
