Document that depmod needs to be executed by hand

External modules don't seem to actually execute depmod on make install,
even though the console output says so. Document that it needs to be
manually executed in the README file.

Makefile: do not run depmod manually

The modules_install target of the kernel build infrastructure already
runs depmod properly, taking into account the cross-compilation
case. Therefore, it is useless to re-run depmod here, and also harmful
since it does not work in cross-compilation contexts (it does the
depmod on the modules installed on the host and not the ones being
built for the target).

ARM: Set bit 0 for thumb mode in kallsyms_lookup_name returned address

This patch fixes the undefined instruction oops due to execution
of thumb-2 code in ARM mode. The zero bit in the symbol address
returned by kallsyms_lookup_name is not set, leading to switching
to ARM mode that generates oops while executing thumb-2 code. For
detailed discussion, see [1].
