[ Upstream commit 6b219431037bf98c9efd49716aea9b68440477a3 ]
In order to debug the kernel successfully with gdb you need to run
'make scripts_gdb' nowadays.
This was changed with the following commit:
Commit 67274c083438340ad16c ("scripts/gdb: delay generation of gdb
constants.py")
In order to have a complete guide for beginners this remark
should be added to the offial documentation.

docs: disable KASLR when debugging kernel2017-07-17T20:49:01ZZhouyi Zhouzhouzhouyi@gmail.com2017-07-07T08:51:45Zurn:sha1:e604f1cb85367d2e5fd4cf253296d190996da81a
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.
