How do
This patch ports the feature Kernel Address SANitizer (KASAN).
Note: The start address of shadow memory is at the beginning of kernel
space, which is 2^64 - (2^39 / 2) in SV39. The size of the kernel space
is 2^38 bytes so the size of shadow memory should be 2^38 / 8. Thus, the
shadow memory
6 matches
