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...?

All kobjects require a dynamically allocated name now. We no longer
need to keep track if the name is statically assigned, we can just
unconditionally free() all kobject names on cleanup.

The latest Intel processors (the 45nm ones) have a model number of 23
(old ones had 15); they're otherwise compatible on the oprofile side.
This patch adds the new model number to the oprofile code.
