On some platforms, eg sparc64, dma_addr_t is not the same size as a
pointer, so printing dma_addr_t values by casting to void * and using
a %p format generates warnings. Fix this by casting to unsigned long
and using %lx instead. This fixes the warnings:
drivers/infiniband/hw/nes/nes_verbs.c: In function 'nes_setup_virt_qp':
drivers/infiniband/hw/nes/nes_verbs.c:1047: warning: cast to pointer from integer of different size

nes_netdev_exit() has no callers, so delete it.

nes_unregister_ofa_device() dereferences the nesibdev pointer before
testing if it's NULL. Also, the test is doubly redundant because the
only caller of nes_unregister_ofa_device() is nes_destroy_ofa_device(),
which already tests if nesibdev is NULL. Remove the unnecessary test.
This was spotted by the Coverity checker (CID 2190).

Christoph Hellwig wants to unexport get_empty_filp(), which is an ugly
internal interface. Change the modular user in ib_uverbs_alloc_event_file()
to use the better alloc_file() interface; this makes the code cleaner too.
Signed-off-by: Roland Dreier <rolandd@cisco.com>

The file member of struct ib_uverbs_event_file was only used to keep
track of whether the file had been closed or not. The only thing we
ever did with the value was check if it was NULL or not. Simplify the
code and get rid of the need to keep track of the struct file * we
allocate by replacing the file member with an is_closed member.

The struct mlx4_interface.event() method was supposed to get an enum
mlx4_dev_event, but the driver code was actually passing in the
hardware enum mlx4_event values. Fix up the callers of
mlx4_dispatch_event() so that they pass in the right type of value,
and fix up the event method in mlx4_ib so that it can handle the enum
mlx4_dev_event values.
This eliminates the need for the subtype parameter to the event
method, so remove it.
This also fixes the sparse warning
drivers/net/mlx4/intf.c:127:48: warning: mixing different enum types
drivers/net/mlx4/intf.c:127:48: int enum mlx4_event versus

The num_interrupt_in, num_bulk_in, and other checks in the usb-serial

many different devices.

Since 43cc71eed1250755986da4c0f9898f9a635cb3bf, the platform modalias is
prefixed with "platform:". Add MODULE_ALIAS() to the hotpluggable serial
platform drivers, to re-enable auto loading.
NOTE that Kconfig for some of these drivers doesn't allow modular builds, and
thus doesn't match the driver source's unload support. Presumably their
unload code is buggy and/or weakly tested...

This fixes DMA on architectures where DMA is nontrivial, like PPC64.
We must use the host-device's (PCI) struct device for any DMA
operation instead of the SSB device. For this we add a new
struct device pointer to the SSB device structure that will always
point to the right device for DMAing.
Without this patch b43 and b44 drivers won't work on complex-DMA
architectures, that for example need dev->archdata for DMA operations.
