gem5 cache automate benchmarks, and remove results that were scattered all over. Move console fun under linux kernel section, since not important enough for getting started. Set arch x86_64 by default through common on all scripts.

# ### lx-symbols after continue
|
|
#
|
|
# lx symbols must be run after continue.
|
|
#
|
|
# running it immediately after the connect on the bootloader leads to failure,
|
|
# likely because kernel structure on which it depends are not yet available.
|
|
#
|
|
# With this setup, continue runs, and lx-symbols only runs when a break happens,
|
|
# either by hitting the breakpoint, or by entering Ctrl + C.
|
|
#
|
|
# Sure, if the user sets a break on a raw address of the bootloader,
|
|
# problems will still arise, but let's think about that some other time.
|
|
#
|
|
# ### lx-symbols autoload
|
|
#
|
|
# The lx-symbols commands gets loaded through the file vmlinux-gdb.py
|
|
# which gets put on the kernel build root when python debugging scripts are enabled.
