There's only the one, in XFS.

  - Add the library function read_cache_pages(), which is used in a
    similar fashion to the single page 'read_cache_page()'. It hides
    the details of the LRU cache etc. from a filesystem that wants to
    to populate an address space with a list of pages.

  - Fix NFS so that readahead uses the ->readpages() interface. Means
    that we can immediately schedule an RPC call in order to complete
    the I/O, rather than relying on somebody later triggering it by
    calling lock_page() (and hence sync_page()). The sync_page()
    method is race-prone, since the waiting page may try to call it
    before we've finished initializing the 'struct nfs_page'.

  - Clear out nfs_sync_page(), the nfs_inode->read list, and
    friends. When the I/O completion gets scheduled in ->readpage(),
    ->readpages(), they have no reason to exist.

The following patch makes the ->readpages() address_space_operation
take a struct file argument just like ->readpage().

This is the second iteration of thread-aware coredumps.

Changes:

- Ulrich Drepper has reviewed the data structures and checked actual
  coredumps via readelf - everything looks fine and according to the spec.

- a serious bug has been fixed in the thread-state dumping code - it was
  still based on the 2.4 assumption that the task struct points to the
  kernel stack - it's task->thread_info in 2.5. This bug caused bogus
  register info to be filled in for threads.

- properly wait for all threads that share the same MM to serialize with
  the coredumping thread. This is CLONE_VM based, not tied to
  CLONE_THREAD and/or signal semantics, ie. old-style (or different-style)
  threaded apps will be properly stopped as well.

  The locking might look a bit complex, but i wanted to keep the
  __exit_mm() overhead as low as possible. It's not quite trivial to get
  these bits right, because 'sharing the MM' is detached from signals
  semantics, so we cannot rely on broadcast-kill catching all threads. So
  zap_threads() iterates through every thread and zaps those which were
  left out. (There's a minimal race left in where a newly forked child
  might escape the attention of zap_threads() - this race is fixed by the
  OOM fixes in the mmap-speedup patch.)

- fill_psinfo() is now called with the thread group leader, for the
  coredump to get 'process' state.

 - initialize the elf_thread_status structure with zeroes.

the IA64 ELF bits are not included, yet, to reduce complexity of the
patch. The patch has been tested on x86 UP and SMP.

In order to conserve CPU, the read(2) syscall would schedule_timeout
unconditionally.  This also crippled speed, and was a bad design
decision.  This cset merges the updated read(2) logic of the sister
driver amd768_rng from Alan, which schedules only when it needs to.
  
On my test system, by one microbenmark, read(2) output jumped
from 0.08 kbit/s to "what Intel expects" of 20 kbit/s.
  
End users may notice a significant decrease in idle time after
this change (and a correspondingly large increase in /dev/hwrng user
speed), if /dev/hwrng is used to its maximum capacity.

Dereferencing hcd.pdev will always oops with SA-1111.  It has to be
treated as a cookie, not a pointer in any common OHCI HCD code.

Apparently we need a clean way to go from struct device * to struct
ohci_hcd *.  I added dev_to_ohci that does the obvious thing and added
separate implementations for PCI and SA-1111.  Two implementations is
ugly but I didn't think it wise (for me) to hack on the PCI/driverfs
interface, so I just cut & paste the old code.

Two patches.  The first is a diff from linux-2.5.44 and
linux-2.5.44-rmk1.  It is from rmk and adds a struct device pointer to
ohci_hcd.  The second depends on the first and contains my changes to
clean up to the pdev oops problems.  (Some fuzz may occur as I have
ohci-1024 applied.)

With these changes, SA111 OHCI-HC/HCD is showing some signs of life on
linux-2.5.44-rmk1.  usb-storage is currentl blowing chunks, but I think
I saw some patches go by against 2.5.44 that I haven't yet tried.

- Add LDFLAGS_BLOB definitions
- Tweak kernel_thread for better code
- Fix vmlinux-armv.lds.in to prevent ld complaining about the
  architecture private flags.
(I'm not certain that the last item isn't a hole in some bug fix in
ld - this fix appears to work with every binutils I've found thus
far.  However, if this suspected bug gets fixed, we're going to have
to rethink how we combine binary objects into ELF objects.)

2.5.46 appears to require drivers/scsi/scsi.h to be included before
drivers/scsi/hosts.h.  Make this happen in the Acorn SCSI drivers.

This completes the kernel-wide audit.

handling (it's "current_text_addr()", not the home-brew
gcc label magic)

Ahm.

No. It must be i_version = 1

Otherwise there is a trivial bug:
    mkdir("dir");
    <force the directory out of dcache>
    dir = open("dir");
    lseek(dir,1,SEEK_SET);
    readdir();

lseek sets f_version to 0, and readdir() trusts f_pos, because i_version
is 0, too. This applies to all filesystems.

The ext2 patch already sets i_version to 1.

This fixes the new ACL bits in fs/ext3 to use C99 designated
initializers.
