6.12-stable review patch. If anyone has any objections, please let me know.

------------------

From: Helge Deller <deller@gmx.de>

commit 8e732934fb81282be41602550e7e07baf265e972 upstream.

The 32MB initial kernel mapping can become too small when CONFIG_KALLSYMS
is used. Increase the mapping to 64 MB in this case.
