[PATCH net 0/3] wireguard fixes for 6.4.2/6.5-rc1

["Jason A. Donenfeld" <Jason@zx2c4.com>]

Hi Jakub,

Sorry to send these patches during the merge window, but they're net
fixes, not netdev enhancements, and while I'd ordinarily wait anyway,
I just got a first bug report for one of these fixes, which I originally
had thought was mostly unlikely. So please apply the following three
patches to net:

1) Make proper use of nr_cpu_ids with cpumask_next(), rather than
   awkwardly using modulo, to handle dynamic CPU topology changes.
   Linus noticed this a while ago and pointed it out, and today a user
   actually got hit by it.

2) Respect persistent keepalive and other staged packets when setting
   the private key after the interface is already up.

3) Use timer_delete_sync() instead of del_timer_sync(), per the
   documentation.

Thanks,
Jason

    key
