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.

"Driver core: fix race in sysfs between sysfs_remove_file() and

sysfs_write_file downs buffer->sem while calling flush_write_buffer, and
flushing that particular write buffer entails downing buffer->sem in

[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:

compile problems with the IPv6 stuff.
So, rip that out and use recv_msg instead. This is a much cleaner interface,

[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.

rcutorture does all of its initialization and thread startup when loaded
and relies on the parameters not changing during execution, so they should
not permit writing. However, reading seems fine.
