Subject: [PATCH net-next 2/2] net: Remove the obsolte u64_stats_fetch_*_irq() users (net).

From: Thomas Gleixner <tglx@...utronix.de>

Now that the 32bit UP oddity is gone and 32bit uses always a sequence
count, there is no need for the fetch_irq() variants anymore.

Convert to the regular interface.
