New MIPS processors, starting with the Warrior
MIPS32r6 code requires FP64 (ie. FR=1) support. Building a kernel with support for MIPS32r6 binaries but without support for O32 with FP64 is therefore a problem which can lead to incorrectly executed userland. CONFIG_MIPS_O32_FP64_SUPPORT is already selected when the kernel is configured for MIPS32r6, but not when the kernel is configured for MIPS64r6 with O32 compat support. Select CONFIG_MIPS_O32_FP64_SUPPORT in such configurations to prevent building kernels which execute MIPS32r6 userland incorrectly.
