xtensa: don't use module_init for non-modular core network.c code

2015-06-16T18:12:31+00:00

The network.c code is piggybacking off of the arch independent CONFIG_NET, which is bool. So the code is either built in or absent. It will never be modular, so using module_init as an alias for __initcall is rather misleading. Fix this up now, so that we can relocate module_init from init.h into module.h in the future. If we don't do this, we'd have to add module.h to obviously non-modular code, and that would be a worse thing. Direct use of __initcall is discouraged, vs prioritized ones. Use of device_initcall is consistent with what __initcall maps onto, and hence does not change the init order, making the impact of this change zero. Should someone with real hardware for boot testing want to change it later to arch_initcall or something different, they can do that at a later date.

xtensa: ISS: fix locking in TAP network adapter

2015-04-13T06:01:00+00:00

- don't lock lp->lock in the iss_net_timer for the call of iss_net_poll, it will lock it itself; - invert order of lp->lock and opened_lock acquisition in the iss_net_open to make it consistent with iss_net_poll; - replace spin_lock with spin_lock_bh when acquiring locks used in iss_net_timer from non-atomic context; - replace spin_lock_irqsave with spin_lock_bh in the iss_net_start_xmit as the driver doesn't use lp->lock in the hard IRQ context; - replace __SPIN_LOCK_UNLOCKED(lp.lock) with spin_lock_init, otherwise lockdep is unhappy about using non-static key.

The code doesn't handle dynamic TAP interface allocation, so there's no point tracking this case. Signed-off-by: Max Filippov Signed-off-by: Chris Zankel

Without proper MAC setup network device doesn't work. IP setup is redundant and may be done with 'ip=...' kernel parameter. Signed-off-by: Max Filippov Signed-off-by: Chris Zankel
