A simple 'grep memset.*\<0);' shows argument order errors in several
uses of memset.

This grep was inspired by Al Viro's recent patch, megaraid_mbox fix,
which fixed this problem in the megaraid driver.

This removes the CRs from the kernel file of Eicon ISDN driver.

Patch from Lennert Buytenhek

The alignment trap handler in arch/arm/mm/alignment.c performs halfword
and word accesses by translating them into byte accessing and then
combining the pieces.  However, it assumes little-endian byte ordering
in doing so, which causes unaligned accesses on big-endian platforms
to erroneously load or store byteswapped data.
This patch was pulled from an old 2.4 -ds tree, and appears to fix the
issue.  It was submitted for 2.4 at the time (ARM patch ID 1205/1206),
but rejected since big-endian ARM platforms are not supported in 2.4.

This fixes the raid5 and raid6 prolems that crept in with the recent
introduction of "bi_max_vecs".

Since raid5/raid6 allocate their own bio's, they need to make sure
that bi_max_vecs is updated along with bi_vcnt.

The vmap vmalloc rework in 2.5 had a unintended side effect.  vmalloc uses
kmalloc now to allocate an array with a list of pages.  kmalloc has a 128K
maximum.  This limits the vmalloc maximum size to 64MB on a 64bit system
with 4K pages.  That limit causes problems with other subsystems, e.g.
iptables relies on allocating large vmallocs for its rule sets.

This is a bug IMHO - on 64bit platforms there shouldn't be such a low limit
on the vmalloc size.  And even on 32bit it's too small for custom kernels
with enlarged vmalloc area.

Another problem is that this makes vmalloc unreliable.  After the system
has been running for some time it is unlikely that kmalloc will be able to
allocate >order 2 pages due to memory fragmentation.

This patch takes the easy way out for fixing this by just allocating this
array with vmalloc when it is larger than a page.  While more complicated
and intrusive solutions would be possible they didn't use vmalloc
recursively they didn't seem it worth to handle this very infrequent case.

Please note that the vmalloc recursion is strictly bounded because each
nested allocation will generate a much smaller stack frame.  Also the
kernel stack can handle even a few recursion steps easily because vmalloc
has only a small stack frame.

This fixes an issue related to the second PCI host controller working on
MPC8555/41 systems.

We track the last PCI bus number on PCI1 so that the PCI2 host
controller can properly exclude itself at the right time, exclusion
should occur after initial setup so that the early pci config cycles in
setting PCI2 actually get to the controller.

My recent do_munmap hugetlb fix has proved inadequate.  There are
other places (madvise, mbind, mlock, mprotect) where split_vma is
called.  Only mprotect excludes a hugetlb vma: the others are in
danger of splitting at a misaligned address, causing later BUGs.

So move the ~HPAGE_MASK check from do_munmap to split_vma itself;
and fix up those places (madvise and mlock) which expect split_vma
can fail only with -ENOMEM, and wish to convert that to -EAGAIN.
(It appears genuine that some of these syscalls should be failing
with -ENOMEM and some with -EAGAIN, so respect those behaviours.)

madvise_dontneed doesn't use split_vma, but is equally in danger
of causing a hugetlb BUG via zap_page_range.  Whereas elsewhere the
patch is permissive (allowing the operation on a hugetlb vma even when
pointless, so long as it doesn't missplit it), here we must use -EINVAL
on any hugetlb vma, since a page fault would hit the BUG in its nopage.

This fixes the mincore syscall in three ways:

 (1) It moves as much argument checking outside of the semaphore-holding
     region as possible.

 (2) It checks the region parameters against TASK_SIZE so that a 32-bit binary
     on a 64-bit platform will get the right error when calling this syscall
     on a region that overlaps the end of the 32-bit address space.

 (3) It tidies up the VMA checking loop a little.

It adds the sleep support for newer powermacs, improve power saving on some
laptops, makes use of the new fbdev modelist management routines, and fixes
a few backlight related issues.

I tested it on a thinkpad T30 and a few PPC boxes with success.  It should
be less invasive than the previous one (I don't try to restore the mode on
exit, that is what breaks the thinkpad and possibly other stuffs that boot
in VGA text mode), plus fixed a couple of bugs in the mode detection code. 
I also reverted the memory map fix on ppc since it doesn't work properly on
some recent laptops where the firmware sets a tiled display.  I'll rework
that completely to update the memory map as part of the mode setting later.
That should fix various issues when switching with X/DRI on x86.

This patch updates aty128fb power management code to the changes of the

chip, etc...  This patch shouldn't break non-ppc, but this should be

The new PowerMac sleep code provides an arch hook that can be used by video
drivers on laptops to bring back the screen very early, pretty much before
anything else.  This basically turns reports of the style "my laptop doesn't
wakeup" to "I get this or this oops/error/panic on wakeup", making fixing the
PM related bugs possible on a whole range of them.

However, the fbdev wakeup code triggers WARN_ON's in the VT subsystem if
called without the console semaphore when redrawing the screen (I added those
warnings a couple of kernel versions ago), and we can't call
acquire_console_sem() since we are so early in the wakeup process that we are
considered as in_atomic() (we hold irqs off too).

This patch addds a try_acquire_console_sem() function that can be used by
those video drivers that implement this early wakeup hook.  If the acquire
fails (which should never happen in practice), wakeup is delayed to the normal
PCI callback which does a blocking acquire_console_sem().

In linux 2.6, PTRACE_SETOPTIONS is redefined to 0x4200, while the old 2.4
value (21) is still available as PTRACE_OLDSETOPTIONS.

So, if UML uses PTRACE_SETOPTIONS, an UML-kernel built on a 2.6 won't run
on a 2.4 host.  Hence we must use PTRACE_OLDSETOPTIONS.

For cases when PTRACE_OLDSETOPTIONS does not exists (i.e.  2.4 host or
archs which miss it because they don't have a "deprecated" value), we
fallback this macro to PTRACE_SETOPTIONS.
