From e8c44319c691dfb4a0b039b095204c040df9b01a Mon Sep 17 00:00:00 2001 From: Ralf Baechle Date: Thu, 18 Oct 2007 03:07:07 -0700 Subject: Replace __attribute_pure__ with __pure To be consistent with the use of attributes in the rest of the kernel replace all use of __attribute_pure__ with __pure and delete the definition of __attribute_pure__.
