d_count == 1 is no guarantee that dentry is on the dentry_unused list, even
if it has just been incremented inside dcache_lock, as dput can decrement
at any time.

This test from Greg Banks is much safer, and is more transparently correct.

From: Kevin Corry <kevcorry@us.ibm.com>

Some testing of DM multipath has turned up a problem with the DEVICE_WAIT
command.  In the tests, while performing a DEVICE_WAIT on a multipath device,
the command sometimes returns immediately, even though the event-number is
correct and no path-failure has occurred to trigger an event.  The problem was
tracked down to the call to schedule() in dev_wait(), which would return even
though it was not woken up by a DM table event.

This patch moves the responsibility for waiting from the ioctl interface into
the core driver, and uses wait_event_interruptible() instead of relying on
wait-queues and schedule().

I noticed that my vmlinux BSS had grown from 17k to 45k between 2.6.5 and
2.6.6.  8k was moving a pair of objects in head.S from the text section to
bss, 8k was the introduction of IRQ stacks, while the remainder (12k) was
page alignment slop, some of it spurious.  The following patch brings BSS
down to the expected 33k.

Throw the IRQ stacks into the page aligned section to avoided wasted BSS
space.  While we'd expect this to save up to 4k, this saves over 10k of BSS
here due to gcc3.3 spuriously aligning other objects in the vicinity.

Currently the get_vsid() and get_kernel_vsid() functions have a test which
enables a different VSID algorithm for debugging.  Using a dumb VSID
algorithm for stressing the hash table is a reasonable debugging tool, but
switching it at runtime makes no sense at all.  Plus it adds another test
and memory access to the performance critical SLB miss path.

This patch removes the test, replacing it with a compile time switch.  It
seems to make a measurable, although small speedup to the SLB miss path
(maybe 0.5%).
