From acf7c8972775a35be318744cc436bdb20b65cebe Mon Sep 17 00:00:00 2001 From: Sasha Levin Date: Thu, 5 Mar 2026 09:48:33 -0500 Subject: Revert "x86/kexec: add a sanity check on previous kernel's ima kexec buffer" This reverts commit c5489d04337b47e93c0623e8145fcba3f5739efd. The commit introduces a call to ima_validate_range() in arch/x86/kernel/setup.c, but the function declaration is not available in the 6.12 stable tree, resulting in build failures due to implicit function declaration errors across multiple stable branches.
