3d73c2884f mlx4_core: Fix section mismatches
Commit ee49bd93 ("mlx4_core: Reset device when internal error is
detected") introduced some section mismatch problems when
CONFIG_HOTPLUG=n, because the error recovery code tears down and
reinitializes the device after everything is loaded, which ends up
calling into lots of code marked __devinit and __devexit from regular
.text.  Fix this by getting rid of these now-incorrect section
markers.

ee49bd9397 mlx4_core: Reset device when internal error is detected
Reset the device when an internal error is detected.

Also, detect errors by polling the error buffer rather than using
interrupts.  This is more robust and doesn't depend on MSI-X.  Remove
the old interrupt handler entirely, since we don't want to support two
mechanisms for detecting internal errors.

2c5cb23558 mlx4_core: Free catastrophic error MSI-X interrupt with correct dev_id
We need to pass the same dev_id to free_irq() and request_irq().  When
using MSI-X, the MLX4_EQ_CATAS interrupt uses a different dev_id from
the other interrupts.

225c7b1fee IB/mlx4: Add a driver Mellanox ConnectX InfiniBand adapters
Add an InfiniBand driver for Mellanox ConnectX adapters.  Because
these adapters can also be used as ethernet NICs and Fibre Channel 
HBAs, the driver is split into two modules: 
 
  mlx4_core: Handles low-level things like device initialization and 
    processing firmware commands.  Also controls resource allocation 
    so that the InfiniBand, ethernet and FC functions can share a 
    device without stepping on each other. 
 
  mlx4_ib: Handles InfiniBand-specific things; plugs into the 
    InfiniBand midlayer.
