X-Git-Tag: v2.6.25-rc1~1143^2~466 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=bfd074e05bdb69652d24ebc60b126899174ca788;p=platform%2Fkernel%2Flinux-3.10.git replace x86_read/write_per_cpu with a common function. x86_read_per_cpu() and its writeish sister are not present in x86_64. So in this patch, we replace them with __get_cpu_var(), which is present in both Signed-off-by: Glauber de Oliveira Costa Signed-off-by: Ingo Molnar Signed-off-by: Thomas Gleixner --- diff --git a/arch/x86/kernel/paravirt.c b/arch/x86/kernel/paravirt.c index 864be04..c20b4f8 100644 --- a/arch/x86/kernel/paravirt.c +++ b/arch/x86/kernel/paravirt.c @@ -238,18 +238,18 @@ static DEFINE_PER_CPU(enum paravirt_lazy_mode, paravirt_lazy_mode) = PARAVIRT_LA static inline void enter_lazy(enum paravirt_lazy_mode mode) { - BUG_ON(x86_read_percpu(paravirt_lazy_mode) != PARAVIRT_LAZY_NONE); + BUG_ON(__get_cpu_var(paravirt_lazy_mode) != PARAVIRT_LAZY_NONE); BUG_ON(preemptible()); - x86_write_percpu(paravirt_lazy_mode, mode); + __get_cpu_var(paravirt_lazy_mode) = mode; } void paravirt_leave_lazy(enum paravirt_lazy_mode mode) { - BUG_ON(x86_read_percpu(paravirt_lazy_mode) != mode); + BUG_ON(__get_cpu_var(paravirt_lazy_mode) != mode); BUG_ON(preemptible()); - x86_write_percpu(paravirt_lazy_mode, PARAVIRT_LAZY_NONE); + __get_cpu_var(paravirt_lazy_mode) = PARAVIRT_LAZY_NONE; } void paravirt_enter_lazy_mmu(void) @@ -274,7 +274,7 @@ void paravirt_leave_lazy_cpu(void) enum paravirt_lazy_mode paravirt_get_lazy_mode(void) { - return x86_read_percpu(paravirt_lazy_mode); + return __get_cpu_var(paravirt_lazy_mode); } struct pv_info pv_info = {
