From 3a1c0fc5927f001d2c70998c08cad42ee5f64849 Mon Sep 17 00:00:00 2001 From: Paul Burton Date: Wed, 1 Aug 2018 13:15:17 -0700 Subject: [PATCH] MIPS: Remove unused sys_32_mmap2 The sys_32_mmap2 function has been unused since we started using syscall wrappers in commit dbda6ac08976 ("MIPS: CVE-2009-0029: Enable syscall wrappers."), and is indeed identical to the sys_mips_mmap2 function that replaced it in sys32_call_table. Remove the dead code.
