Mark Rutland b02faed15d arm64: Use larger stacks when KASAN is selected ... AddressSanitizer instrumentation can significantly bloat the stack, and with GCC 7 this can result in stack overflows at boot time in some configurations. We can avoid this by doubling our stack size when KASAN is in use, as is already done on x86 (and has been since KASAN was introduced). Regardless of other patches to decrease KASAN's stack utilization, kernels built with KASAN will always require more stack space than those built without, and we should take this into account.
