x86: oprofile: remove NR_CPUS arrays in arch/x86/oprofile/nmi_int.c
Change the following arrays sized by NR_CPUS to be PERCPU variables:
static struct op_msrs cpu_msrs[NR_CPUS];
static unsigned long saved_lvtpc[NR_CPUS];
Also some minor complaints from checkpatch.pl fixed.
Based on:
git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux-2.6.git
git://git.kernel.org/pub/scm/linux/kernel/git/x86/linux-2.6-x86.git
All changes were transparent except for:
static void nmi_shutdown(void)
{
+ struct op_msrs *msrs = &__get_cpu_var(cpu_msrs);
nmi_enabled = 0;
on_each_cpu(nmi_cpu_shutdown, NULL, 0, 1);
unregister_die_notifier(&profile_exceptions_nb);
- model->shutdown(cpu_msrs);
+ model->shutdown(msrs);
free_msrs();
}
The existing code passed a reference to cpu 0's instance of struct op_msrs
to model->shutdown, whilst the other functions are passed a reference to
<this cpu's> instance of a struct op_msrs. This seemed to be a bug to me
even though as long as cpu 0 and <this cpu> are of the same type it would
have the same effect...?
