Subject: [PATCH v3 0/2] printk: CONFIG_BASE_SMALL fix for LOG_CPU_MAX_BUF_SHIFT and removal

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 replace CONFIG_BASE_SMALL usages by the
equivalent !CONFIG_BASE_FULL.

Patch history:
v2 -> v3: Applied Luis Chamberlain's comments (Thanks!):
* Split the single commit in two : one functional fix, one global
  removal.

v2 patch was named "printk: Remove redundant CONFIG_BASE_SMALL"
https://lore.kernel.org/all/20240127220026.1722399-1-yoann.congal@smile.fr/
* Reviewed-by: Masahiro Yamada <masahiroy@...nel.org>
* Reviewed-by: John Ogness <john.ogness@...utronix.de>

v1 -> v2: Applied Masahiro Yamada's comments (Thanks!):
* Changed from "Change CONFIG_BASE_SMALL to type bool" to
  "Remove it and switch usage to !CONFIG_BASE_FULL"
* Fixed "Fixes:" tag and reference to the mailing list thread.
* Added a note about CONFIG_LOG_CPU_MAX_BUF_SHIFT changing.

v1 patch was named "treewide: Change CONFIG_BASE_SMALL to bool type"
https://lore.kernel.org/all/20240126163032.1613731-1-yoann.congal@smile.fr/
