In file included from <command-line>:
arch/powerpc/kernel/module.c: In function 'module_alloc':
include/linux/compiler_types.h:320:38: error: call to '__compiletime_assert_171'
declared with attribute error: BUILD_BUG_ON failed: TASK_SIZE > MODULES_VADDR
I don't think there is much we can do about that.
TASK_SIZE is set to 0xb0000000 by default on BOOK3S/32 in Kconfig.
If the user forces a greater value without increasing PAGE_OFFSET accordingly, it won't work. The
BUILD_BUG_ON() is there to catch it.
