Remove myself as networking maintainer. I haven't done much for networking
for a long time and it doesn't look likely it'll change anytime soon.
Also David/Alexey are doing a fine job without me.

Here is the big 2.5.21 x86-64 sync patch. It only touches arch/x86_64
and include/asm-x86_64. It requires a few other changes that I'm sending
in separate mail.

Changes:
- merge wit 2.5.21
- merge from 2.5.21/i386 (new PCI code, new LDT code etc.)
- sync with 2.4-x86_64 tree.
- minor updates to 32bit emulation
- better early console; including serial support.
- now set up dummy PDA for booting to avoid problems
- Fix GS reloading in context switch one instruction race
- Remove hardcoded names from mpparse code
- Fix inline assembly for RAID-5 xor (similar change needed for i386)
- Real per cpu data support based on PDA field
- Cleanup of offset.c generation requested by Kai: it only puts structure
  offsets into offset.h now.
- Fix i387 fxsave signal frame problems.
- Add uname emulation via personality ("linux32")
- New SSE optimized checksum-copy, copy*user, memcpy, clear_page, copy_page
  functions. Other tunings/cleanups in checksum and other user memory
  access function.
- check if exception table is really sorted
- Cleanups in page table handling in preparation of non executable pages
  support.
- Cleanup PDA access to not require offset.h (thanks to kai for kicking me
  to this)
- use long long for u64/s64 to avoid more warnings
- remove CONFIG_ISA
- fix various bugs and other cleanups

  enable/disable preemption to not spend too much time with
  preemption disabled. wait_task_inactive() can take quite some
  time occasionally ...

  set p->thread_info->cpu directly if the task is not running
  and is not on any runqueue.

Recent header cleanup broke this driver. Needs #include <linux/init.h>

ACPI interpreter update
Change non-interpreter code to account for the interpreter changes.

This update gets things compiling again after a device model change.

This adds preliminary support for _TRA resource on PCI root bridges (Bjorn
Helgaas)

end_request(int) turned to end_request(req, int); all old callers
are converted to end_request(CURRENT, value).  Now we can start
killing CURRENT/QUEUE - end_request() was the last obstacle to
that.

ditto for DEVICE_INTR/CLEAR_INTR.  do_mfm/do_acsi/do_hd/... are
explicitly declared in the drivers that use DEVICE_INTR stuff;
DEVICE_INTR/CLEAR_INTR is gone from blk.h.

#define DEVICE_NAME ... removed from the drivers that never use
that macro.

monstrous cascade of #ifdefs is gone from blk.h.  This is the first
step of cleanup - we move #define in question into the code that
includes blk.h (i.e. DEVICE_NR, DEVICE_NAME and DEVICE_INTR are
explicitly set by drivers).

->s_dev is switched to dev_t.  Everything that uses it uses it as
a number - i.e. all instances are either minor() or kdev_t_to_nr().

->j_dev is gone from reiserfs journal.  All its uses had been replaced
with use of ->j_dev_bd; it's simply not used anymore.

get_super() split in two functions - get_super(bdev) and
user_get_super(dev_t).  Callers that used get_super() to get superblock
by (dev_t) syscall argument switched to the latter; the rest had
block_device in question and switched to passing it.

ROOT_DEV converted to dev_t.  There's no reason for it to be kdev_t -
it's both used as a number and set as a number.

do_getattr() renamed to vfs_getattr(), exported and used by
loop.c and nfsd - both blindly accessed ->i_dev/->i_ino of
random inodes when they ought to be calling ->getattr() to
get that information.

misc gratitious kdev_t uses fixed (janitorial stuff - e.g. quota
patches had reintroduced kdevname(sb->s_dev) in places where we'd
switched to sb->s_id, etc.)

added bdev_read_only() - analog of is_read_only() using block_device.
Almost all callers of is_read_only() converted.

sget()/generic_shutdown_super() cleaned up; fixed error handling
in sget()

FS_NOMOUNT is gone, initialization for pseudo-filesystems
(bdev, pipe, sock) switched to use of a common helper.

compile fixes (missing includes + obvious fix in adfs/map.c)

pay attention to the return value of usb_control_msg as found by the CHECKER tool.

pay attention to return value of usb_submit_urb as found by the CHECKER tool.

This is a collected patch for USB drivers to use the new list macros
(list_del_init, list_move*).

 - Sync with 2.5.21

 - Don't call put_device inside idedisk_cleanup(). This is apparently triggering
   some bug inside the handling of device trees. Or we don't register the device
   properly within the tree. Check this later.

 - Further work on the channel register file access locking.  Push the locking
   out from __ide_end_request to ide_end_request.  Rename those functions to
   respective __ata_end_request() and ata_end_request().

 - Move ide_wait_status to device.c rename it to ata_status_poll().

 - Further work on locking scope issues.

 - devfs showed us once again that it changed the policy from agnostic numbers
   to unpleasant string names.

The subject says it all...

Contrary to other proposed patches I realized that there is
no such thing as vmalloc_dma.
