From 8d0e051cc75e2b1a7e2fd51fc56af332c9619618 Mon Sep 17 00:00:00 2001 From: Helge Deller Date: Fri, 10 May 2019 17:00:01 +0200 Subject: parisc: Enable the ro_after_init feature This patch modifies the initial page mapping functions in the following way: During bootup the init, text and data pages will be mapped RWX and if supported, with huge pages. At final stage of the bootup, the kernel calls free_initmem() and then all pages will be remapped either R-X (for text and read-only data) or RW- (for data). The __init pages will be dropped. This reflects the behaviour of the x86 platform.
