Benoit Cousson [Wed, 29 Feb 2012 18:40:31 +0000 (19:40 +0100)]
mfd: Move twl-core IRQ allocation into twl[4030|6030]-irq files

During DT adaptation, the irq_alloc_desc was added into twl-core, but
due to the rather different and weird IRQ management required by the twl4030,
it is much better to have a different approach for it.
The issue is that twl4030 uses a two level IRQ mechanism but handles all the
PWR interrupts as part of the twl-core interrupt range. It ends up with a
range of 16 interrupts total for CORE and PWR.

The other twl4030 functionalities already have a dedicated driver and thus
their IRQs and irqdomain can and should be defined localy.

twl6030 is using a single level IRQ controller and thus does not require any
trick.

Move the irq_alloc_desc and irq_domain_add_legacy in twl4030-irq and
twl6030-irq.

Allocate together CORE and PWR IRQs for twl4030-irq.

   problem, from Jan Weitzel.

4) Fix buffer overrun and unicast sterring bugs in mellanox mlx4 driver,
   from Eugenia Emantayev.

5) Swapped kcalloc() args in RxRPC and mlx4, from Axel Lin.

6) PHY MDIO device name regression fixes from Florian Fainelli.

7) If the wake event IRQ line is different from the netdevice one, we
   have to properly route it to the stmmac interrupt handler.  From
   Francesco Virlinzi.

8) Fix rwlock lock initialization ordering bug in mac80211, from
   Mohammed Shafi Shajakhan.

9) TCP lost_cnt can get out of sync, and in fact go negative, in certain
   circumstances.  Fix the way we specify what sequence range to operate
   on in tcp_sacktag_one() to fix this bug.  From Neal Cardwell.
