Yes

Yes. I add Your patch to -rc4 and rfkill works OK:
Enable by button:
root@...is:/home/maciek# rfkill list
0: phy0: Wireless LAN
        Soft blocked: no
        Hard blocked: no
1: hci0: Bluetooth
        Soft blocked: no
        Hard blocked: no
2: hp-wifi: Wireless LAN
        Soft blocked: no
        Hard blocked: no
3: hp-bluetooth: Bluetooth
        Soft blocked: no
        Hard blocked: no

Disable by button:
root@...is:/home/maciek# rfkill list
0: phy0: Wireless LAN
        Soft blocked: no
        Hard blocked: yes
2: hp-wifi: Wireless LAN
        Soft blocked: no
        Hard blocked: no
3: hp-bluetooth: Bluetooth
        Soft blocked: no
        Hard blocked: no

After resume from s2disk:
root@...is:/home/maciek# rfkill list
2: hp-wifi: Wireless LAN
        Soft blocked: no
        Hard blocked: no
3: hp-bluetooth: Bluetooth
        Soft blocked: no
        Hard blocked: no
4: phy1: Wireless LAN
        Soft blocked: no
        Hard blocked: yes

(are some differences after and before s2disk)

Enable by button:
root@...is:/home/maciek# rfkill list
2: hp-wifi: Wireless LAN
        Soft blocked: no
        Hard blocked: no
3: hp-bluetooth: Bluetooth
        Soft blocked: no
        Hard blocked: no
4: phy1: Wireless LAN
        Soft blocked: no
        Hard blocked: no
5: hci0: Bluetooth
        Soft blocked: no
        Hard blocked: no

And wifi/bluetooth works without manual enable. Thanks.
