[PATCH] arm64/mm: Drop redundant extern declaration for rodata_full

From: Anshuman Khandual

Date: Tue Oct 14 2025 - 22:36:16 EST


Drop the redundant extern declaration 'rodata_full' which can be included
via the header <asm/setup.h> after moving exiting declaration outside the
function arch_parse_debug_rodata(). While here also drop 'rodata_enabled'
which is anyways available via the generic header <linux/init.h>.
