b55fcb22d4 revert "proc: fix the threaded proc self"
Revert commit c6caeb7c45 ("proc: fix the
threaded /proc/self"), since Eric says "The patch really is wrong.
There is at least one corner case in procps that cares."

8811930dc7 splice: missing user pointer access verification
vmsplice_to_user() must always check the user pointer and length
with access_ok() before copying. Likewise, for the slow path of
copy_from_user_mmap_sem() we need to check that we may read from
the user region.

66191dc622 quota: turn quotas off when remounting read-only
Turn off quotas before filesystem is remounted read only.  Otherwise quota
will try to write to read-only filesystem which does no good...  We could
also just refuse to remount ro when quota is enabled but turning quota off
is consistent with what we do on umount.

28ae094c62 ext3 can fail badly when device stops accepting BIO_RW_BARRIER requests
Some devices - notably dm and md - can change their behaviour in response
to BIO_RW_BARRIER requests.  They might start out accepting such requests
but on reconfiguration, they find out that they cannot any more.

ext3 (and other filesystems) deal with this by always testing if
BIO_RW_BARRIER requests fail with EOPNOTSUPP, and retrying the write
requests without the barrier (probably after waiting for any pending writes
to complete).

However there is a bug in the handling for this for ext3.

When ext3 (jbd actually) decides to submit a BIO_RW_BARRIER request, it
sets the buffer_ordered flag on the buffer head.  If the request completes
successfully, the flag STAYS SET.

Other code might then write the same buffer_head after the device has been
reconfigured to not accept barriers.  This write will then fail, but the
"other code" is not ready to handle EOPNOTSUPP errors and the error will be
treated as fatal.

This can be seen without having to reconfigure a device at exactly the
wrong time by putting:

		if (buffer_ordered(bh))
			printk("OH DEAR, and ordered buffer\n");

in the while loop in "commit phase 5" of journal_commit_transaction.

If it ever prints the "OH DEAR ..." message (as it does sometimes for
me), then that request could (in different circumstances) have failed
with EOPNOTSUPP, but that isn't tested for.

My proposed fix is to clear the buffer_ordered flag after it has been
used, as in the following patch.

2dafe1c4d6 reduce large do_mount stack usage with noinlines
do_mount() uses a whopping 616 bytes of stack on x86_64 in 2.6.24-mm1,
largely thanks to gcc inlining the various helper functions.

noinlining these can slim it down a lot; on my box this patch gets it down
to 168, which is mostly the struct nameidata nd; left on the stack.

These functions are called only as do_mount() helpers; none of them should
be in any path that would see a performance benefit from inlining...

535ee2fbf7 buffer_head: fix private_list handling
There are two possible races in handling of private_list in buffer cache.

1) When fsync_buffers_list() processes a private_list, it clears
   b_assoc_mapping and moves buffer to its private list.  Now
   drop_buffers() comes, sees a buffer is on list so it calls
   __remove_assoc_queue() which complains about b_assoc_mapping being
   cleared (as it cannot propagate possible IO error).  This race has been
   actually observed in the wild.

2) When fsync_buffers_list() processes a private_list,
   mark_buffer_dirty_inode() can be called on bh which is already on the
   private list of fsync_buffers_list().  As buffer is on some list (note
   that the check is performed without private_lock), it is not readded to
   the mapping's private_list and after fsync_buffers_list() finishes, we
   have a dirty buffer which should be on private_list but it isn't.  This
   race has not been reported, probably because most (but not all) callers
   of mark_buffer_dirty_inode() hold i_mutex and thus are serialized with
   fsync().

Fix these issues by not clearing b_assoc_map when fsync_buffers_list()
moves buffer to a dedicated list and by reinserting buffer in private_list
when it is found dirty after we have submitted buffer for IO.  We also
change the tests whether a buffer is on a private list from
!list_empty(&bh->b_assoc_buffers) to bh->b_assoc_map so that they are
single word reads and hence lockless checks are safe.

d20894a237 Remove a.out interpreter support in ELF loader
Following the deprecation schedule the a.out ELF interpreter support
is removed now with this patch. a.out ELF interpreters were an transition
feature for moving a.out systems to ELF, but they're unlikely to be still
needed. Pure a.out systems will still work of course. This allows to
simplify the hairy ELF loader.

1ed161718a udf: fix 3 signedness & 1 unitialized variable warnings
sparse generated:
fs/udf/inode.c:324:41: warning: incorrect type in argument 4 (different signedness)
fs/udf/inode.c:324:41:    expected long *<noident>
fs/udf/inode.c:324:41:    got unsigned long *<noident>

inode_getblk always set 4th argument to uint32_t value
3rd parameter of map_bh is sector_t (which is unsigned long or u64)
so convert phys value to sector_t

udf_get_filelongad and udf_get_shortad are called always for uint32_t
values (struct extent_position->offset), so it's safe to convert offset
parameter to uint32_t

gcc warned:
fs/udf/inode.c: In function 'udf_get_block':
fs/udf/inode.c:299: warning: 'phys' may be used uninitialized in this function
initialize it to 0 (if someday someone will break inode_getblk we will catch it immediately)

sparse generated:
fs/udf/dir.c:78:5: warning: symbol 'udf_readdir' was not declared. Should it be static?
there are 2 different prototypes of udf_readdir - remove them and move
code around to make it still compile

a9ca663578 kill UDFFS_{DATE,VERSION}
Printing date and version of a driver makes sense if there's a maintainer
who's maintaining and using these, but printing ancient version information
only confuses users.
