Subject: [PATCH v4 0/3] printk: CONFIG_BASE_SMALL fix for LOG_CPU_MAX_BUF_SHIFT and removal of CONFIG_BASE_FULL

This series focuses on CONFIG_BASE_SMALL.
The first patch fixes LOG_CPU_MAX_BUF_SHIFT when CONFIG_BASE_SMALL is
used.
The second patch globally changes the type of CONFIG_BASE_SMALL and
adapts usages.
The third patch removes the now redundant BASE_FULL and puts BASE_SMALL
in its place in the config menus.

Thanks everyone for your reviews! :)
