Brian spotted a stupid bug in the slab initialization:

If multiple objects fit into one cacheline, then the allocator ignores
SLAB_HWCACHE_ALIGN and squeezes the objects into the same cacheline.  The
implementation contains an off by one error and thus doesn't work correctly:
For Athlon optimized kernels, the 32-byte slab uses 64 byte of memory.

From: Eric Piel <Eric.Piel@Bull.Net>

Fixes some long/int confusion on 64-bit machines which was causing failures
on ia64 - we end up trying to set bits in the 32-63 range on an int and the
kernel locks up.

Also cleans up idr.h.

George has acked this change.

The patch is designed to help locate where the kernel is dying during the
startup sequence.

- Boot parameter "initcall_debug" causes the kernel to print out the
  address of each initcall before calling it.

  The kallsyms tables do not cover __init sections, so printing the
  symbolic version of these symbols doesn't work.  They need to be looked up
  in System.map.

- Detect whether an initcall returns with interrupts disabled or with a
  locking imbalance.  If it does, complain and then try to fix it up.

Don't allow "bind_request" to be called before "register_pccard_driver".

This fixes ipmi compilation (with some documentation updates and another
minor fix, too).

It also fixes a problem with the state machine getting stuck in a
certain error condition.

we're writing over TCP and have done a partial send.

  The following patch by Joe Korty removes an over-zealous check in the NFS
  read code that causes pages to be incorrectly marked with PG_error and
  hence causes an EIO to be returned to userland.

  The test is incorrect as it ignores the fact that we may be caching a
  write that will extend the file on the server (and hence will create a
  hole in the region concerned.).

a null 'p_proc' procedure pointer.

and drop the 'flags' argument (it was always set too LOOKUP_PARENT).

If the user supplies and empty path, return -ENOENT.

Doing this ensures that we keep probing the connection to the server
rather than just waiting for the entire congestion window to time out.
The latter can be very expensive due to the exponential backoff rule.

Also reformat some printks so lines don't exceed 80chars.

This fixes an oops caused by incorrect usage of sector_div()
in which_dev() in md/linear.c.  It was dereferencing an non-existent
hash table entry.

We currently hold a read_lock of dparent_lock
while calling exp_get_by_name on several ancestors
of a given dentry.  However exp_get_by_name can
malloc(GFP_KERNEL), so that isn't a good idea.

Now we only claim the lock while actually
stepping up the parent chain.

This addresses bug 29 @ bugme.osdl.org

encode_read: change 'len' variable from unsigned long to a long for
'(len > 0)' comparison.  don't set up a tail iovec for zero length
reads.

NFSv4 operations after WRITE are decoded into wr_vec[] pages, thus the
argp->pagelen can be non-zero at the end of decoding the WRITE
operation.

This patch correctly sets argp->pagelen, and correctly advances argp->p
after the WRITE operation

Fix some misleading comments, and correct the test for requesting more
than one page.
