From 9132a2e82adc6e5a1c7c7385df3bfb25576bdd80 Mon Sep 17 00:00:00 2001 From: Christophe Leroy Date: Thu, 1 Apr 2021 13:30:42 +0000 Subject: [PATCH] powerpc/8xx: Define a MODULE area below kernel text On the 8xx, TASK_SIZE is 0x80000000. The space between TASK_SIZE and PAGE_OFFSET is not used. In order to benefit from the powerpc specific module_alloc() function which allocate modules with 32 Mbytes from end of kernel text, define MODULES_VADDR and MODULES_END. Set a 256Mb area just below PAGE_OFFSET, like book3s/32.
