This reverts commit 39d61db0edb34d60b83c5e0d62d0e906578cc707.

The commit was buggy in multiple ways:
 - the conversion to ilog2() was incorrect to begin with
 - it tested the wrong #defines, so on all architectures but FRV you'd
   never see the bug except for constant arguments.
 - the new "get_order()" macro used its arguments multiple times, and
   didn't even parenthesize them properly
 - despite the comments, it was not true that you could use it for
   constant initializers, since not all architectures even use the
   generic page.h header file.

All of the problems are individually fixable, but it all boils down to:
better just revert it, and re-do it from scratch.

[PATCH] Fix buffer overflow in Omnikey CardMan 4040 driver (CVE-2007-0005)

Based on a patch from Don Howard <dhoward@redhat.com>

When calling write() with a buffer larger than 512 bytes, the
driver's write buffer overflows, allowing to overwrite the EIP and
execute arbitrary code with kernel privileges.

In read(), there exists a similar problem, but coming from the device.
A malicous or buggy device sending more than 512 bytes can overflow
of the driver's read buffer, with the same effects as above.

[PATCH] suspend regression: sysfs deadlock

Suspend deadlocks when trying to unregister /sys/block/sr0.

This comes from Oliver's commit 94bebf4d1b8e7719f0f3944c037a21cfd99a4af7
"Driver core: fix race in sysfs between sysfs_remove_file() and
read()/write()".

sysfs_write_file downs buffer->sem while calling flush_write_buffer, and
flushing that particular write buffer entails downing buffer->sem in
orphan_all_buffers, resulting in the obvious self-deadlock.

[IA64] kexec: Use EFI_LOADER_DATA for ELF core header

The address where the ELF core header is stored is passed to the secondary
kernel as a kernel command line option.  The memory area for this header is
also marked as a separate EFI memory descriptor on ia64.

The separate EFI memory descriptor is at the moment of the type
EFI_UNUSABLE_MEMORY.  With such a type the secondary kernel skips over the
entire memory granule (config option, 16M or 64M) when detecting memory.
If we are lucky we will just lose some memory, but if we happen to have
data in the same granule (such as an initramfs image), then this data will
never get mapped and the kernel bombs out when trying to access it.

So this is an attempt to fix this by changing the EFI memory descriptor
type into EFI_LOADER_DATA.  This type is the same type used for the kernel
data and for initramfs.  In the secondary kernel we then handle the ELF
core header data the same way as we handle the initramfs image.

This patch contains the kernel changes to make this happen.  Pretty
straightforward, we reserve the area in reserve_memory().  The address for
the area comes from the kernel command line and the size comes from the
specialized EFI parsing function vmcore_find_descriptor_size().

The kexec-tools-testing code for this can be found here:

[IA64] permon use-after-free fix

Perfmon associates vmalloc()ed memory with a file descriptor, and installs
a vma mapping that memory.  Unfortunately, the vm_file field is not filled
in, so processes with mappings to that memory do not prevent the file from
being closed and the memory freed.  This results in use-after-free bugs and
multiple freeing of pages, etc.

Provide a module param "pool_mode" for sunrpc.ko which allows a sysadmin to
choose the mode for mapping NFS thread service pools to CPUs.  Values are:

auto     choose a mapping mode heuristically
global     (default, same as the pre-2.6.19 code) a single global pool
percpu     one pool per CPU
pernode     one pool per NUMA node

Note that since 2.6.19 the hardcoded behaviour has been "auto", this patch
makes the default "global".

The pool mode can be changed after boot/modprobe using /sys, if the NFS and
lockd services have been shut down.  A useful side effect of this change is to

[PATCH] knfsd: fix recently introduced problem with shutting down a busy NFS server

When the last thread of nfsd exits, it shuts down all related sockets.  It
currently uses svc_close_socket to do this, but that only is immediately
effective if the socket is not SK_BUSY.

If the socket is busy - i.e.  if a request has arrived that has not yet been
processes - svc_close_socket is not effective and the shutdown process spins.

So create a new svc_force_close_socket which removes the SK_BUSY flag is set
and then calls svc_close_socket.

Also change some open-codes loops in svc_destroy to use
list_for_each_entry_safe.

[PATCH] knfsd: use recv_msg to get peer address for NFSD instead of code-copying

The sunrpc server code needs to know the source and destination address for
UDP packets so it can reply properly.  It currently copies code out of the
network stack to pick the pieces out of the skb.  This is ugly and causes
compile problems with the IPv6 stuff.

So, rip that out and use recv_msg instead.  This is a much cleaner interface,
but has a slight cost in that the checksum is now checked before the copy, so
we don't benefit from doing both at the same time.  This can probably be

[PATCH] cciss: fix for 2TB support

This patch changes the way we determine if a logical volume is larger than
2TB.

The original test looked for a total_size of 0.  Originally we added 1 to the
total_size.  That would make our read_capacity return size 0 for >2TB lv's.
We assumed that we could not have a lv size of 0 so it seemed OK until we were
in a clustered system.  The backup node would see a size of 0 due to the
reservation on the drive.  That caused the driver to switch to 16-byte CDB's
which are not supported on older controllers.  After that everything was
broken.

It may seem petty but I don't see the value in trying to determine if the LBA
is beyond the 2TB boundary.  That's why when we switch we use 16-byte CDB's
for all read/write operations.  Please consider this for inclusion.
