From 4e7d9f25f137a7f5d765439dceb35826378a925a Mon Sep 17 00:00:00 2001 From: Leon Hwang Date: Wed, 15 Jul 2026 21:12:58 +0800 Subject: mm/mseal: fix mseal documentation for 32-bit kernels MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit mseal.o is built only for 64-bit kernels, so 32-bit kernels fall back to sys_ni_syscall() and return -ENOSYS rather than -EPERM. Drop architecture description in mseal.rst, since the arch feature doc has the latest state of mseal for each architecture. Fix the CONFIG_MSEAL_SYSTEM_MAPPINGS typo in init/Kconfig.
