Patch 3/5 (Update to version 6.17)
* Add: Removed SkNumber and SkDoDiv
* Add: Counter output as (unsigned long long)

Patch 1/5 (Update to version 6.17)
* Add: Better parameter check
* Add: UDP and TCP HW Csum changes
* Add: Interrupt Moderation infos

Add proper management of jiffies and time values, rather than punting
and doing long long arithmetic on usecs.

Still more driver data which was updated but never used.

Convert bogus test_and_set local wait, to a real spin_lock so it
has a chance of working on an SMP.  This also does the right thing
and locks out interrupts while giving commands on UP;  maybe the
comment in Kconfig was because there was never a proper mutex...

Don't have real hardware to try this, but it can't be worse than
the previous code.

Still more places state is saved and never used.

Get rid of extra trailing semicolons

Get rid of unneeded casts to cleanup readability.

This code is littered with unused structure elements and globals.
Eliminate some of the fields set and never used.

More in later patches.

The arlan driver tries to build it's /proc interface into a separate module,
which leads to circular dependencies and other ugliness.  This patch
moves arlan.c to arlan-main.c and changes initialization builds one module arlan.o

Patch is for 2.6.0-test5

here is a new version of the sk98lin driver (v6.18) with some changes
for kernel 2.6.0-test4. This is a diff between the latest patched kernel
version with sk98lin driver v6.17.

Patch 1/3
* Remove bogus config stuff

	Fix for typo in arch/mips/kernel/sysirix.c (spotted by Milton Miller)

From: Stephen Smalley <sds@epoch.ncsc.mil>

I believe that the patch below fixes the legitimate leaks in the SELinux
code.  In some cases, it rearranges the code (moving the allocation later
to reduce the need for further cleanup or linking the object into a
containing structure earlier so that the policydb_destroy will handle it
upon any subsequent errors).

From: Christoph Hellwig <hch@lst.de>

Still three arches keep an unused copy around and quite a few places refer
to it in comments still.

Two of the two arches also include it in their _ksyms.c file, but given
that softirq.h only contains macros (which are in hardirq.c as well) that's
just a leftover as well.

Use common (normalized) asm syntax for lidt/lgdt, specifying that the
operand is an input value instead of output.

Fix wanxl for older gcc's, and fix a couple of warnings.

From: Dave Olien <dmo@osdl.org>

this patch fixes a bug that appeared only on Alpha hardware with
DAC960 controllers.  The Command->PciDevice structure member was
never initialized.  This was passed to the pci scatter/gather functions.
This didn't cause a problem for x86 platforms because the scatter/gather
funtions never really used that information.  Alpha platforms do use
that pointer.

The Command->PciDevice field was also redundant with the Controller->PCIDevice
field, which IS initialized properly.  So, eliminating the redundant
structure member and substituting the Controller's member fixes the bug.

CONFIG_SERIAL_21285_OLD depends on the non-existent option CONFIG_OBSOLETE,
IOW it's not selectable, and the help text says "This is obsolete and will
be removed during later 2.5 development.".

	I noticed that contrary to what was happening with 2.4.x kernel, suid

	Is this the intended behaviour or a bug ?

	Example :

	[root@localhost test]# chown root ~cartaljp/test/suid_test
	[root@localhost test]# chmod 4775 ~cartaljp/test/suid_test
	[root@localhost test]# exit
	[cartaljp@localhost test]$ cp /bin/ls suid_test
	[cartaljp@localhost test]$ ls -l
	total 72
	-rwsrwxr-x    1 root     cartaljp    67668 Sep 19 07:56 suid_test <-
	Suid bit is still set whereas with 2.4.x kernel it was reset.

Yes. Here 2.4 had the terrible code

     mode = (inode->i_mode & S_IXGRP)*(S_ISGID/S_IXGRP) | S_ISUID;

while 2.6 does things via notify_change().  However, in 2.6 notify_change()
does not allow removal of the SUID bit because you are not owner of the
file :-).  So, we have to convince inode_change_ok() to do it anyway.

At present you can set CONFIG_HUGETLB_PAGE and not CONFIG_HUGETLBFS, which
give the kernel low-level hugepage support, but no userspace API with which
to access it.

And with the recent hugetlbfs-accounting fix, the low-level code needs
functions which are in hugetlbfs, so CONFIG_HUGETLBFS=n,
CONFIG_HUGETLB_PAGE=y doesn't even link.

So we flip things around: CONFIG_HUGETLB_PAGE is set if CONFIG_HUGETLBFS is
set and CONFIG_HUGETLB_PAGE is unset if CONFIG_HUGETLBFS is unset.  The
CONFIG_HUGETLB_PAGE option hence disappears from the per-arch configuration
menus.

From: "Chen, Kenneth W" <kenneth.w.chen@intel.com>

We found a problem in hugetlbfs file system quota when using huge page
via mmap.  The mmap method in hugetlbfs_file_operation always takes
quota for every mmap even for pages that are already allocated on that
inode.  This results in taxing the same hugepage multiple times and
causing mmap to fail on existing file when quota mistakenly runs out.

All drivers that compile on ppc with CONFIG_ISA set (= all but
some m68-only drivers), I looked at the compile warnings very
closely and there are no new warnings or even errors this time :)

drivers/char/Makefile needed to be reordered big time to keep
the intialization order the same.

From: Ethan Benson <erbenson@alaska.net>

Currently Linux allows the use of the utime() and utimes() syscalls on
immutable or append-only files, this is incorrect.

utime{s}() is not supposed to work if you lack write access to a file,
in the case of an immutable file NOBODY has write access.

for an append-only file it only makes sense to be able to update its
time to present, not the past.

I have checked BSD, and they implement the behavior I propose, for
immutable files utime() and utimes() fail.  for append-only files they
fail if the time argument is not NULL.

From: John Levon <levon@movementarian.org>

Not that many people are going to be using GCC 3.4 currently, but it
might help a bit to prevent compilation bugs like that just witnessed
in procfs.

(And it consolidates the check_gcc implementation nicely)

Some junk which was needed before we did the big cleansweep for the sysrq
syncing stuff.

From: Christoph Hellwig <hch@lst.de>

Richard hasn't touched it for about a year and since then only bugfixes and
my changes to the kernel interface went in.  No one has stepped up to
maintain it and with udev we have a proper replacement now.

I will do some more work before 2.6 (mainly trying to implement Al's
refcounting scheme to avoid stale entries), but that's it.

From: "David S. Miller" <davem@redhat.com>

It's from Ingo Molnar.  ksoftirqd kicks in way too early, so do more work in
interrupt context before falling back.

We can probably sysctl this thing, that way everyone gets what they want
probably...

(has been in -mm since 2.5.71 and I haven't heard a peep).

From: Manfred Spraul <manfred@colorfullife.com>

- Remove cache_alloc_one_tail and cache_alloc_listfixup - there is no
  reason for their existance.

- Print a bit more debugging info when slab corruption is detected.

	Argh.  A couple of places where we needed ..._encode_dev() had
been lost in reordering the patchset - the most notable being ctty number in
/proc/<pid>/stat.  Fix follows:

This fixes several things including fixing the character ioctl polling
to use wait_event_interruptible_timeout() instead of
interruptible_sleep_on_timeout() and several other fixes.

These changes were already applied to 2.4.22.
