From 0fc74d820a012550be006ba82dd8f1e3fe6fa9f7 Mon Sep 17 00:00:00 2001 From: Linus Torvalds Date: Mon, 25 Apr 2022 01:28:01 -0700 Subject: no-MMU: expose vmalloc_huge() for alloc_large_system_hash() It turns out that for the CONFIG_MMU=n builds, vmalloc_huge() was never defined, since it's defined in mm/vmalloc.c, which doesn't get built for the no-MMU configurations. Just implement the trivial wrapper for the no-MMU case too. In fact, just make it an alias to the existing __vmalloc() function that has the same signature.
