bpf: Fix pointer cast warning
kp->addr is a pointer, so it cannot be cast directly to a 'u64' when it gets interpreted as an integer value: kernel/trace/bpf_trace.c: In function '____bpf_get_func_ip_kprobe': kernel/trace/bpf_trace.c:968:21: error: cast from pointer to integer of different size [-Werror=pointer-to-int-cast] 968 | return kp ? (u64) kp->addr : 0; Use the uintptr_t type instead. Fixes: 9ffd9f3ff719 ("bpf: Add bpf_get_func_ip helper for kprobe programs") Signed-off-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Andrii Nakryiko <andrii@kernel.org> Link: https://lore.kernel.org/bpf/20210721212007.3876595-1-arnd@kernel.org
