Subject: docs: disable KASLR when debugging kernel

From: Zhouyi Zhou <[email protected]>

commit e604f1cb85367d2e5fd4cf253296d190996da81a upstream.

commit 6807c84652b0 ("x86: Enable KASLR by default") enables KASLR by default on x86. While KASLR will confuse gdb which resolve kernel symbol address from symbol table of vmlinux. We should turn off KASLR for kernel debugging.
