[PATCH] arm64: Allow disabling of the compat vDSO

2019-09-25 Thread Catalin Marinas
The compat vDSO building requires a cross-compiler than produces AArch32 binaries, defined via CONFIG_CROSS_COMPILE_COMPAT_VDSO or the CROSS_COMPILE_COMPAT environment variable. If none of these is defined, building the kernel always prints a warning as there is no way to deselect the compat vDSO.
