From 390dfd95c5df1ab3921dd388d11b2aee332c3f2c Mon Sep 17 00:00:00 2001 From: Tejun Heo Date: Thu, 29 Oct 2009 22:34:14 +0900 Subject: percpu: make misc percpu symbols unique This patch updates misc percpu related symbols such that percpu symbols are unique and don't clash with local symbols. This serves two purposes of decreasing the possibility of global percpu symbol collision and allowing dropping per_cpu__ prefix from percpu symbols. * drivers/crypto/padlock-aes.c: s/last_cword/paes_last_cword/ * drivers/lguest/x86/core.c: s/last_cpu/lg_last_cpu/ * drivers/s390/net/netiucv.c: rename the variable used in a macro to avoid clashing with percpu symbol * arch/mn10300/kernel/kprobes.c: replace current_ prefix with cur_ for static variables. Please note that percpu symbol current_kprobe can't be changed as it's used by generic code. Partly based on Rusty Russell's "alloc_percpu: rename percpu vars which cause name clashes" patch.
