From 48ae93fdd133849cf8e0a46a525cb09229933c8b Mon Sep 17 00:00:00 2001 From: Paul Burton Date: Wed, 1 Aug 2018 13:15:18 -0700 Subject: MIPS: Delete unused code in linux32.c The A() & AA() macros have been unused since commit 05e4396651ca ("[MIPS] Use SYSVIPC_COMPAT to fix various problems on N32"), which switched to the more standard compat_ptr(). RLIM_INFINITY32, RESOURCE32() & struct rlimit32 have been present but unused since the beginning of the git era. Remove the dead code.
