This allows machine classes to override ISA_DMA_THRESHOLD as
necessary.

Clean up bzImage target, remove a couple of obsolete testing targets,
and add better bootpImage help text.

This fixes the buggy decompressor assembly, and fixes PCMCIA IO
to use the correct byte lane when accessing certain PCMCIA cards.

Static data causes GOTOFF relocations to be used, which won't work
because we want to relocate the .data section separately from the
.text section.  Therefore, force all data to be nonstatic.

- use 'Image' target for kernel image to be compressed rather than
  duplicating its generation.
- use .incbin-based generation of ELF objects from binary data rather
  than 'ld'-based generation.

For clarity and consistency, use the same name for makefile and
linker symbols.

Since this is where these two variables are used, it makes sense to
have them in that makefile.  Also, consolidate "targets"
initialisation, fixes a missing FORCE dependency for the uImage rule,
and remove more FTVPCI code.

- fix up for kbuild changes
- run users own kernel install script if present

CAP_DAC_OVERRIDE fails to give search permission in a directory with

For each node there are a defined list of MAX_NR_ZONES zones.  These are
selected as a result of the __GFP_DMA and __GFP_HIGHMEM zone modifier flags
being passed to the memory allocator as part of the GFP mask.  Each node
has a set of zone lists, node_zonelists, which defines the list and order
of zones to scan for each flag combination.  When initialising these lists
we iterate over modifier combinations 0 ..  MAX_NR_ZONES.  However, this is
only correct when there are at most ZONES_SHIFT flags.  If another flag is
introduced zonelists for it would not be initialised.

This patch introduces GFP_ZONETYPES (based on GFP_ZONEMASK) as a bound for
the number of modifier combinations.

Like a few other drivers the vc driver is doing unlocked careless
references to file offsets.  Its got kind of 2.2 locking that hasnt been
updated in the lseek function so someone at least tried. 

Fortunately we have a real lock for this and can just make lseek use that
too.

Here's the accel capabilities patch for radeonfb.  It updates radeonfb to
advertise its acceleration capabilities via fbinfo.flags.  I've tested this
on my box, and it gives me a nice fast console.

defect: "$ fbset -accel 0" doesn't work for radeonfb -- disabling accel
will only work from the kernel command line :-/

This has been reported a couple of times and is consistently causing some
folks grief, so Urban, would you mind terribly if i send this patch to at
least clear current bug reports.  If there is additional stuff you want
ontop of this let me know and i can send a follow up patch.

The bug is that at times we haven't completed setting up the smb_ops so we
have a temporary 'null' ops in place until the connection is completely up.
 With this setup it's possible to hit ->readdir() whilst the null ops are
still in place, so we put the process to sleep until the connection setup
is complete and then call the real ->readdir().

If a fault in the kernel leads to an unexpected protection fault whilst in
a code path which holds mmap_sem we will deadlock in do_page_fault() while

we can detect and OOPS on the vast majority of these, greatly enhancing

Jeremy Katz of Red Hat reported that his iSeries machine would not boot
with 2.6.7 based kernels.

It appears that with the inclusion of Paul Mackerras' patch "Optimize
exception/syscall entry/exit" a small previous patch got reverted.  Here
is that patch again.  The lack of this patch does not stop all iSeries
machines booting, but it does stop some.

We permanently hold the i_sem of swapfiles so that nobody can addidentally
ftruncate them, causing subsequent filesystem destruction.

Problem is, it's fairly easy for things like backup applications to get
stuck onthe swapfile, sleeping until someone does a swapoff.

So take all that out again and add a new S_SWAPFILE inode flag.  Test that
in the truncate path and refuse to truncate an in-use swapfile.

Synchronisation between swapon and truncate is via i_sem.

ext3_direct_io_get_blocks() is misinterpreting the return value from
ext3_journal_extend(), and is consequently running out of buffer credits and
going BUG on tremendously large direct-io writes.  Fix that up.

Also, I note that the really large direct-io writes can hold a transaction
open for the entire duration, which can be minutes.  This violates ext3's
attempt to commit data at regular intervals.  Fix that up by looking at the
transaction state: if it's T_LOCKED, shut off the current handle so the
pending commit can complete.

Vladimir Saveliev reported anon_vma_unlink list_del BUG (LKML 24 June). 
His testing is still in progress, but we believe it comes from a nasty
locking deficiency I introduced in 2.6.7's anon_vma_prepare.

Andrea's original anon_vma_prepare was fine, it needed no anon_vma lock
because it was always linking a freshly allocated structure; but my
find_mergeable enhancement let it adopt a neighbouring anon_vma, which of
course needs locking against a racing linkage from another mm - which the
earlier adjust_vma fix seems to have made more likely.

Does anon_vma->lock nest inside or outside page_table_lock?  Inside, but
that's not obvious without a lock ordering list: instead of listing the
order here, update the list in filemap.c; but a separate patch because
that's less urgent and more likely to get wrong or provoke controversy.

(Could do it with anon_vma lock after dropping page_table_lock, but a long
comment explaining why some code is safe suggests it's not.)
