From e4c4bf9968cb4f0fceb1b8fb54790ccae73caf4e Mon Sep 17 00:00:00 2001 From: Jeff Dike Date: Sun, 15 Jul 2007 23:38:56 -0700 Subject: uml: Eliminate kernel allocator wrappers UML had two wrapper procedures for kmalloc, um_kmalloc and um_kmalloc_atomic because the flag constants weren't available in userspace code. kern_constants.h had made kernel constants available for a long time, so there is no need for these wrappers any more. Rather, userspace code calls kmalloc directly with the userspace versions of the gfp flags. kmalloc isn't a real procedure, so I had to essentially copy the inline wrapper around __kmalloc. vmalloc also had its own wrapper for no good reason. This is now gone.
