Remove the old backward-compatible quota interface.

The patch also contains a renaming of functions vfs_{get|set}_info() to
vfs_{get|set}_dqinfo() and minor compilation fix needed for 2.5.18
(include <linux/namei.h>).

This changes the sysctl interface to use reasonable names in
/proc/sys/fs/quota/

I ported the quota changes to 2.5.18.  The first one is just a minor
change to Makefile and Config.in to not build quota.c when not needed.

- Simplify the ide-pci code further.

 - Merge ide-probe.c and ide-features.c in to one single file.  They are
   mutually doing basically the same and in esp. in case of the device ID
   retrieval there *is* quite a lot of code duplication between them.
   ide-geometry.c fits there as well.

 - Remove ide_xfer_verbose - it wasn't really used.

 - Don't allow check_partition to be more clever then the writer of a driver.
   It was interfering with drivers which check partitions as they go and
   finally if we want to spew something about it - we can do it ourself.

 - Eliminate ide_geninit(). We scan for partitions now inside the recently
   introduced attach method. register_disk() is broken by the way and 90% of
   places where it's used it is doing literally nothing. Either some one didn't
   finish some code or the code is basically just junk from the past.

   Anyway we grok the partitions now one by one as we detect the channels.

 - ide_driveid_update is gone. We don't report the drive id through /proc/ide
   and we don't have to update it any longer on the fly. Still someone out there
   complaining that it went away!?

 - Use the global driver spin-lock to protect data structure access in the
   ide_register_subdriver() function instead of blatantly disabling all
   interrupts.

This patch fixes the bug which happens when utf8 option was used,
by using iocharset for upper/lower conversion.

It's a bit strange that utf8 use iocharset, but this is still needed.

This implements what we discussed, basically just maintaing a plug list
from the block layer as a direct parallel to the tq_disk task queue we
had before.  blk_run_queues() now splices the blk_plug_list to avoid
holding the blk_plug_lock across all the request_fn calls.

Don't include Rules.make in the top-level Makefile, we don't
actually build anything from there, so we don't need the rules.

If asked to build some file in a subdirectory, descend into the
subdir and build it from there - only there we can know what
extra flags etc we have to add.

This also works for building preprocessed [.i] and assembler
output [.s].

The asm stub for thermal_interrupt was not being created.

Targets should always be built from the Makefile local to the subdir
they are in. So build scripts/* from scripts/Makefile.

Clean up scripts/Makefile as we go.

Basically only cosmetics, and move the 'update-modverfile:'
rule from Rules.make to the top-level Makefile, since that's the
only place where it's used.

My name is *not* GPL: you may not derive works without approval.

PS.  I've also applied for a patent...

access to it by the time we start copying arguments.

We don't actually use it at this point yet.

We currently decide whether we need to descend into the subdirs of
drivers/ in drivers/Makefile, but link the resulting objects from
the top-level Makefile.

Making these two decisions at the same time (in drivers/Makefile) cleans
up the top-level Makefile quite a bit.

Link order does not change at all apart from sound/, which is now linked
last.

The remaining cleanups are to switch to using pfn instead of vaddr, and
improve readability.

This revised patch starts untangling the mess in arch/i386/mm/init.c
- Pull setting bits in cr4 out of the loop
- Make __PAGE_KERNEL a variable and cache the global bit there.
- New pfn_pmd() for large pages.

Cleans up some redundant code in head.S:
- Combine checking of AC and ID eflags.
- Streamline the setting of %cr0.

This will eventually allow us to copy argc/argv without
any intermediate storage (removing current argument size
limitations).

Many Makefiles did a put an own rule in front of 
"include $(TOPDIR)/Rules.make" for no good reason at all,
the only places where it made sense are converted to using
EXTRA_TARGETS now.

Remove obsolete NFS and RPC routines.
Remove 'inline' attribute from xdr_decode_fattr().

Remove another class of rpciod deadlocks on HIGHMEM systems. Kick habit of
keeping pages kmap()ed for the entire duration of NFS
read/readdir/readlink operations.

Use struct page directly in RPC client data receive buffer. TCP and UDP
sk->data_ready() bottom-halves copy (and checksum when needed) data into
pages rather than iovecs. atomic_kmap() of single pages is used for the
copy.

include/linux/xdr.h
   Declare structure for copying an sk_buff here rather than in xprt.c.
   Forward declaration of new functions.

include/linux/sunrpc/xprt.h
   RPC client receive buffer changed to use new format 'struct xdr_buf'.

net/sunrpc/clnt.c
   Initialize new format receive buffer.

net/sunrpc/sunrpc_syms.c
   Export xdr_inline_pages(), xdr_shift_buf()

net/sunrpc/xdr.c
   xdr_inline_pages() inlines pages into the receive buffer.
   xdr_partial_copy_from_skb() replaces csum_partial_copy_to_page_cache()
	and copy code in tcp_read_request(). Provides sendfile()-style
	method for copying data from an skb into a struct xdr_buf.
   xdr_shift_buf() replaces xdr_shift_iovec() for when we overestimate
	the size of the RPC/NFS header.

net/sunrpc/xprt.c
   Adapt UDP and TCP receive routines to use new format xdr_buf.

include/linux/nfs_xdr.h
   struct nfs_readargs, nfs_readdirargs, nfs_readlinkargs,
	nfs3_readdirargs, nfs3_readlinkargs all transmit page information.
   struct nfs_readdirres, nfs_readlinkres, nfs3_readlinkres obsoleted.
   struct nfs_rpc_ops->readlink(), readdir(), read() now send pages

fs/nfs/dir.c
   Adapt to new format ->readdir().
   Avoid kmap() around the RPC call.

fs/nfs/read.c
   Adapt to new format ->read() and struct nfs_readargs.

fs/nfs/symlink.c
   Adapt to new format ->readlink().

fs/nfs/proc.c
   Convert nfs_proc_readlink(), nfs_proc_readdir(), nfs_proc_read()

fs/nfs/nfs2xdr.c
   Convert XDR routines to transmit page information.
   Remove duplicate zeroing of pages when server returns a short read.

fs/nfs/nfs3proc.c
   Convert nfs3_proc_readlink(),nfs3_proc_readdir(),nfs3_proc_read()

fs/nfs/nfs3xdr.c
   Convert XDR routines to transmit page information.
   Remove duplicate zeroing of pages when server returns a short read.

Stop rpciod from deadlocking against itself in map_new_virtual() on HIGHMEM
systems. RPC client currently has to keep all pages that are scheduled for
transmission kmap()ed into an iovec for the entire duration of the call.
We only actually need to kmap() pages while making the (non-blocking)
call to sock_sendmsg().

NOTE: When transmitting several pages in one RPC call, sock_sendmsg()
requires us to kmap() *all* those pages at the same time. Opens for
deadlocks between rpciod and some other process that also kmaps more
than 1 page at a time.
For the TCP case we can solve later by converting to TCP_CORK+sendpage().

include/linux/sunrpc/xdr.h
   Introduce 'struct xdr_buf' in order to allow RPC layer to handle
   pages directly.

include/linux/sunrpc/xprt.h:
   Convert the RPC client send-buffer to the new format.

net/sunrpc/clnt.c
   Initialize the new format RPC send-buffer.

net/sunrpc/sunrpc_syms.c
   Export xdr_encode_pages()

net/sunrpc/xdr.c
   xdr_kmap() kmap()+copy a struct xdr_buf into an iovec array.
   xdr_kunmap() clean up after xdr_kmap().
   xdr_encode_pages() used to inline pages for transmission.

net/sunrpc/xprt.c
   xprt_sendmsg() needs to kmap() the pages into an iovec for transmission.

include/linux/nfs_xdr.h
   struct nfs_writeargs transmits full page information.
   Convert nfs_rpc_ops->write() to send pages.

fs/nfs/write.c
   Adapt to new format nfs_writeargs / nfs_rpc_ops->write()

fs/nfs/proc.c
   Convert nfs_proc_write().

fs/nfs/nfs2xdr.c
   Convert nfs_xdr_writeargs()

fs/nfs/nfs3proc.c
   Convert nfs3_proc_write().

fs/nfs/nfs3xdr.c
   Convert nfs3_xdr_writeargs()

PPPoATM uses tasklet_disable() on a tasklet inside a struct and then
frees the struct, leaving a pointer to the freed tasklet inside tasklet
lists.

This patch replaces tasklet_disable() with tasklet_kill().
