We need some alignement of those structs for proper operations especially
with FP and Altivec, or SLAB_DEBUG can break us.

This patch just adds some proc entries for the virtual tape and cdrom
drivers to allow mapping between linux devices and OS/400 ones.  This is
expected by existing users and there is no other way to do this
translation.

Without this the task struct gets unaligned when using SLAB_DEBUG, causing
random problems with FP and Altivec.

The patch below from Michael E.  Brown properly sets the owner field of a
sysfs attribute.  Without this patch, it is possible to crash the kernel with
a simultaneous insmod/rmmod while reading files exported by the module.

This patch fixes loading viocd as a module.  It would oops because I was
passing the address of a static buffer to dma_map_single and when loaded as
a module, this address is not valid for that purpose.

There are a couple of simple cleanups here as well.

It no longer has any callers.

Brad Spengler <spender@grsecurity.net> found an exploitable bug in the proc handler
of cpufreq, where a user-supplied unsigned int is cast to a signed int and then
passed on to copy_[to|from]_user() allowing arbitary amounts of memory to be written
(root only thankfully), or read (as any user).

The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned
the name CAN-2004-0228 to this issue.

From Dominik.

One big limitation of the ACPI specification is that it's impossible to
detect the current P-State by reading from ACPI-defined registers. And the
CPU isn't always at P0 when the system boots. So, try to "guess" the current
P-State by analyzing cpu_khz.

From Dominik.

If used as a bootparam, this would've become powernow-k7.powernow_acpi_force which looks silly.

This updates the lkkbd driver to it's current version.

It also incorporates two patches suggested on LKML (fixing
some leading whitespace and an unneccessary check).

This  updates the vsxxx driver to it's current version.

Even DEC tablet support (VSXXX-AB) is now tested - it works:)
You can even hotplug between mouse and digitizer...

This patch is needed due to other patches that were applied in parallel
with the inclusion of the iSeries virtual ethernet driver.

From: Pavel Roskin <proski@gnu.org>

The "ide-cs" module cannot be unloaded because it uses obsolete
MOD_INC_USE_COUNT and MOD_DEC_USE_COUNT macros.  In fact, they are not
needed in ide-cs.c in 2.6 kernels.  The generic PCMCIA code already
increases use count for every device served by the driver, so it's
impossible to unload the ide-cs driver while it's in use.

I was told that the removal of IDE interfaces may be unsafe in 2.6
kernels.  However, MOD_INC_USE_COUNT only prevents removal of the module,
not the interface.  It's also the first obstacle, albeit a trivial one,
for anybody debugging those problems (i.e. loading a modified module
requires "rmmod -f" or reboot to unload the old version).

If I eject IDE CompactFlash card, I get a stack dump from
devfs_remove() because ide/host2/bus0/target0/lun0 doesn't exist.

After del_gendisk() is called from idedisk_cleanup() drive->devfs_name refers
to a non-existent directory and should be erased, so that ide_unregister()
doesn't try to remove that directory again.

I have found small inconsistency in loop_set_fd().  It checks if
->sendfile() is implemented for passed block device file.  But in fact,
loop back device driver never calls it.  It uses ->sendfile() from backing
store file.

From: William Lee Irwin III <wli@holomorphy.com>

i386 does hardware interpretation of pagetables, so pte_clear() can't be
used on present ptes, as it sets the upper half of the hugepte prior to
setting the lower half (which includes the valid bit).  i.e.  there is a
window where having a hugepage mapped at 56GB and doing pte_clear() in
unmap_hugepage_range() allows other threads of the process to see a
hugepage at 0 in place of the original hugepage at 56GB.

This patch corrects the situation by using ptep_get_and_clear(), which
clears the lower word of the pte prior to clearing the upper word.

There is another nasty where huge_page_release() needs to wait for TLB
flushes before returning the hugepages to the free pool, analogous to the
issue tlb_remove_page() and tlb_flush_mm() repair.
