Use copy_to_user/get_char with user buffers.

This patch against 2.5.70-bk2 removes the buffer allocation from resource.c
and lets seq_read do it instead.

From: Hugh Dickins <hugh@veritas.com>

Remove shmem_nrpages, no use is made of it (even 2.4-ac, though it counts
it, does nothing with it): reintroduce if it becomes useful.  Replace GPL
oneliner by the block from 2.4-ac, extend Copyright to 2003, remove two
white spaces.

From: Hugh Dickins <hugh@veritas.com>

Dissatisfied with earlier fix to race where swapoff sneaks page into tmpfs
page cache after truncate_inode_pages cleaned it: calling it a second time
can be too heavy, instead fix shmem_unuse_inode to check i_size.
(Actually, one part of this fix is in the previous patch: shmem_file_write
now has a hold on the page when it raises i_size.)

From: Hugh Dickins <hugh@veritas.com>

generic_file_aio_write_nolock has recently been corrected for when partial
writes hit -EFAULT: now bring shmem_file_write into line.

loop_get_buffer loses PF_MEMDIE if it's added while in loop_copy_bio: not a
high probability since it's not waiting there, but could happen, and sets a
bad example (compare with add_to_swap fixed a while back).

From: Hugh Dickins <hugh@veritas.com>

loop_copy_bio uses one gfp_mask for bio_alloc and alloc_page calls.  The
bio_alloc obviously can't use highmem, but the alloc_page can.  Yes, the
underlying device might be unable to use highmem, and have to use one of
its bounce buffers, with an extra copy: so be it.

(Originally I did propagate the underlying device's bounce needs down to
the loop device, to avoid that possible extra copy; but let's keep this
simple, the low end doesn't have highmem and the high end can I/O it.)

What purpose does loop_make_request's blk_queue_bounce serve?  None, it's
just a relic from before the kmaps were added to loop's transfers, and ties
up mempooled resources - in the file-backed case, with no guarantee they'll
soon be freed.  And what purpose does loop_set_fd's blk_queue_bounce_limit
serve?  None, blk_queue_make_request did that.

From: Hugh Dickins <hugh@veritas.com>

Jonah Sherman <jsherman@stuy.edu> pointed out back in February how
LO_FLAGS_BH_REMAP is never actually set, since loop_init_xfer only calls
the init for non-0 encryption type.  Fix that or scrap it?  Let's scrap it
for now, that path (hacking values in bio instead of copying data) seems
never to have been tested, and adds to the number of paths through loop:
leave that optimization to some other occasion.

From: Hugh Dickins <hugh@veritas.com>

Remove unused IV from loop_make_request (loop_transfer_bio does that).

From: Hugh Dickins <hugh@veritas.com>

Remove copy flag and code from loop_copy_bio: wasn't used when reading, and
waste of time when writing - the loop transfer function does that.  And
don't initialize bio fields immediately reinitialized by caller.

From: Hugh Dickins <hugh@veritas.com>

Now it's in loop not bio, better rename bio_copy to loop_copy_bio: loop
prefers names that way; and bio_transfer better named loop_transfer_bio.
Rename bio,b to rbh,bio to follow call from loop_get_buffer more easily.

From: Hugh Dickins <hugh@veritas.com>

bio_copy is used only by the loop driver, which already has to walk the bio
segments itself: so it makes sense to change it from bio.c export to loop.c
static, as prelude to working upon it there.

bio_copy itself is unchanged by this patch, with one exception.  On oom
failure it must use bio_put, instead of mempool_free to static bio_pool:
which it should have been doing all along - it was leaking the veclist.

(Grudgingly acked by Jens)

From: Hugh Dickins <hugh@veritas.com>

When loop restricts underlying file's allocation mask to avoid deadlock, it
unintentionally masks out its highmem capability, making failures at the
underlying level much more likely.

currently only x86_64 and ia64 don't use the generic irq_cpustat code
and both have to workaround it's brokenness for the non-default case.

x86_64 defines an empty irq_cpustat_t even if it doesn't need one and
ia64 adds CONFIG_IA64 ifdefs around all users.  What about this patch
instead to make __ARCH_IRQ_STAT useable?

Ensure that the arch exit routines are always called when needed,
previously we could end up with a nasty crash if using oprofile.timer=1,
or the FS register failed.

Remove some useless code, from Philippe Elie.

Update the version information.

Export the task->tgid to userspace as well. This is needed
for forthcoming thread profiling stuff and should have been
done in the original patch ... oh well.

This requires an upgrade to oprofile 0.5.3. You can get it from
the website, or, for the impatient, here :

Patch from Nicolas Pitre

The -march=armv5te issue looks to be fixed in gcc-3.3.
Since gcc-3.3 is the only gcc version >= 3 that seems to correctly
compile kernels out of the box I think it would be reasonable to
apply this patch and no bother with older gcc versions.

Yet gcc-3.3 emits V5TE instructions only when -mcpu=xscale is used,
but that seems to have been fixed in current CVS so next gcc release
will use all available instructions properly with -march=armv5te.

Patch from Deepak Saxena

This patch adds some hooks to arch/arm/Makefile to enable proper building
of big-endian kernels.  It also adds an option to the the top level
arm KConfig that only allows a big-endian kernel to be built if the sub-arch
KConfig sets the CONFIG_ARCH_SUPPORTS_BIG_ENDIAN boolean to true. This is
mainly there to keep people from attemtpting to build a big-endian kernel
for a system that is not capable of running in big-endian mode.

Rename the socket_info_t inside tcic.c to struct tcic_socket. At one
time there were at least five different "socket_info_t" within cardmgr
/ linux/drivers/pcmcia. Let's get rid of all of them to avoid
confusion in future.

Rename the socket_info_t inside tcic.c to struct i82365_socket. At one
time there were at least five different "socket_info_t" within cardmgr
/ linux/drivers/pcmcia. Let's get rid of all of them to avoid
confusion in future.

The i82365 doesn't work unless CONFIG_ISA is set -- see this from
i82365_init:

...

    sockets = 0;

#ifdef CONFIG_ISA
    isa_probe();
#endif

    if (sockets == 0) {
        printk("not found.\n");
        driver_unregister(&i82365_driver);
        return -ENODEV;
    }

...

So, remove all instances of CONFIG_ISA from i82365.c and add a
dependency to the Kconfig file.

Get rid of the

typedef struct pcmcia_socket socket_info_t;

by replacing all remaining usages of cs_internal's socket_info_t with
struct pcmcia_socket.

Linus said [on April 25th of this year]:
> There are two reasons I did pci_socket, and one of them is stale
> and the other one is a matter of taste.

As the second reason is stale now, too, unify yenta.c and
pci_socket.c.

Remove socket_no from struct pcmcia_bus_socket - it's only used in
printks, and the one additional level of indirection doesn't hurt there.
