The PCI MSI interface is stubbed out properly so that all the
functions just return failure if PCI_MSI=n, so there's no reason to
have "#ifdef CONFIG_PCI_MSI" blocks in ipath_iba7220.c.

Before IBA7220 support was added, the ipath driver didn't support any
hardware unless PCI_MSI and/or HT_IRQ was enabled. However, the
IBA7220 can generate INTx interrupts, so it makes sense to allow the
driver to be build even if PCI_MSI=n and HT_IRQ=n.

The new IBA7220 code added a call to ipath_init_iba7220_funcs() that
is compiled unconditionally, but only built the IBA7220 code if
PCI_MSI is enabled. Fix this by building the IBA7220 file
unconditonally.
This fixes build breakage when PCI_MSI=n, HT_IRQ=y and
INFINIBAND_IPATH=y reported by Ingo Molnar <mingo@elte.hu>:
drivers/built-in.o: In function `ipath_init_one':

Commit 124b4dcb ("IB/ipath: add calls to new 7220 code and enable in
build") inadvertently added core to set dev->class_dev.dev back into
ib_ipath. This is completely redundant since commit 1912ffbb ("IB: Set
class_dev->dev in core for nice device symlink"), which removed
class_dev setting from low-level drivers, and also will break the build
when class_dev is removed completely from struct ib_device.

Fixed trivial conflict in include/linux/memory.h due to semaphore header
file change (made irrelevant by the change to mutex).
This sets us up to be able to convert the srp_host to use a struct
device instead of a class_device.
Based on a original patch from Tony Jones, but split up into this piece
by Greg.

None of these files use any of the functionality promised by
asm/semaphore.h. It's possible that they rely on it dragging in some
unrelated header file, but I can't build all these files, so we'll have
fix any build failures as they come up.

If a P_Key is deleted and then re-added at the same index, then IPoIB
gets confused because __ipoib_ib_dev_flush() only checks whether the
index is the same without checking whether the P_Key was present, so
the interface is stopped when the P_Key is deleted, but the event when
the P_Key is re-added gets ignored and the interface never gets
restarted.
Also, switch to using ib_find_pkey() instead of ib_find_cached_pkey()
everywhere in IPoIB, since none of the places that look for P_Keys are
in a fast path or in non-sleeping context, and in general we want to
kill off the whole caching infrastructure eventually. This also fixes
consistency problems caused because some IPoIB queries were cached and
some were uncached during the window where the cache was not updated.
Thanks to Venkata Subramonyam <vsubramo@cisco.com> for debugging this
problem and testing this fix.

When a RDMA_CM_EVENT_DEVICE_REMOVAL event is raised, iSER should

This is necessary when the IB HCA module is unloaded while open-iscsi

Move the free_irq() call in nes_remove() to before the tasklet_kill();
otherwise there is a window after tasklet_kill() where a new interrupt
can be handled and reschedule the tasklet, leading to a use-after-free
