The check to determine which format string is appopriate for u64 and
friends works in most cases, but UML on x86_64 doesn't define CONFIG_X86_64,
so it results in screen fulls of compile-time warnings.
This patch fixes it to handle that case.

This patch adds mm->task_size to keep track of the task size of a given mm
and uses that to fix the powerpc vdso so that it uses the mm task size to
decide what pages to fault in instead of the current thread flags (which
broke when ptracing).
(akpm: I expect that mm_struct.task_size will become the way in which we
finally sort out the confusion between 32-bit processes and 32-bit mm's. It
may need tweaks, but at this stage this patch is powerpc-only.)

If negative entries (nodeid == 0) were sent in reply to LOOKUP requests,
two bugs could be triggered:
- looking up a negative entry would return -EIO,
- revaildate on an entry which turned negative would send a FORGET
request with zero nodeid, which would cause an abort() in the
library.
The above would only happen if the 'negative_timeout=N' option was used,
otherwise lookups reply -ENOENT, which worked correctly.

I'm currently at the POSIX meeting and one thing covered was the
incompatibility of Linux's link() with the POSIX definition. The name.
Linux does not follow symlinks, POSIX requires it does.
Even if somebody thinks this is a good default behavior we cannot change this
because it would break the ABI. But the fact remains that some application
might want this behavior.
We have one chance to help implementing this without breaking the behavior.
For this we could use the new linkat interface which would need a new
flags parameter. If the new parameter is AT_SYMLINK_FOLLOW the new
behavior could be invoked.
I do not want to introduce such a patch now. But we could add the
parameter now, just don't use it. The patch below would do this. Can we
get this late patch applied before the release more or less fixes the
syscall API?

This change reverts the 033b96fd30db52a710d97b06f87d16fc59fee0f1 commit
from Kay Sievers that removed the mount/umount uevents from the kernel.
Some older versions of HAL still depend on these events to detect when a
new device has been mounted. These events are not correctly emitted,
and are broken by design, and so, should not be relied upon by any
future program. Instead, the /proc/mounts file should be polled to
properly detect this kind of event.
A feature-removal-schedule.txt entry has been added, noting when this
interface will be removed from the kernel.

Fix a deadlock possible in the ext2 file system implementation. This
deadlock occurs when a file is removed from an ext2 file system which was
mounted with the "sync" mount option.
The problem is that ext2_xattr_delete_inode() was invoking the routine,
sync_dirty_buffer(), using a buffer head which was previously locked via
lock_buffer(). The first thing that sync_dirty_buffer() does is to lock
the buffer head that it was passed. It does this via lock_buffer(). Oops.
The solution is to unlock the buffer head in ext2_xattr_delete_inode()
before invoking sync_dirty_buffer(). This makes the code in
ext2_xattr_delete_inode() obey the same locking rules as all other callers
of sync_dirty_buffer() in the ext2 file system implementation.

If 2 threads attached to the same process are blocking on different locks on
different files (maybe even on different servers) but have the same lock
arguments (i.e. same offset+length - actually quite common, since most
processes try to lock the entire file) then the first GRANTED call that wakes
one up will also wake the other.
Currently when the NLM_GRANTED callback comes in, lockd walks the list of
blocked locks in search of a match to the lock that the NLM server has
granted. Although it checks the lock pid, start and end, it fails to check
the filehandle and the server address.
By checking the filehandle and server IP address, we ensure that this only
happens if the locks truly are referencing the same file.

With David Woodhouse <dwmw2@infradead.org>
select() presently has a habit of increasing the value of the user's
`timeout' argument on return.
We were writing back a timeout larger than the original. We _deliberately_
round up, since we know we must wait at _least_ as long as the caller asks
us to.
The patch adds a couple of helper functions for magnitude comparison of
timespecs and of timevals, and uses them to prevent the various poll and
select functions from returning a timeout which is larger than the one which
was passed in.
The patch also fixes a bug in compat_sys_pselect7(): it was adding the new
timeout value to the old one and was returning that. It should just return
the new timeout value.
(We have various handy timespec/timeval-to-from-nsec conversion functions in
time.h. But this code open-codes it all).

The *at patches introduced fstatat and, due to inusfficient research, I
used the newfstat functions generally as the guideline. The result is that
on 32-bit platforms we don't have all the information needed to implement
fstatat64.
This patch modifies the code to pass up 64-bit information if
__ARCH_WANT_STAT64 is defined. I renamed the syscall entry point to make
this clear. Other archs will continue to use the existing code. On x86-64
the compat code is implemented using a new sys32_ function. this is what
is done for the other stat syscalls as well.
This patch might break some other archs (those which define
__ARCH_WANT_STAT64 and which already wired up the syscall). Yet others
might need changes to accomodate the compatibility mode. I really don't
want to do that work because all this stat handling is a mess (more so in
glibc, but the kernel is also affected). It should be done by the arch
maintainers. I'll provide some stand-alone test shortly. Those who are
eager could compile glibc and run 'make check' (no installation needed).
The patch below has been tested on x86 and x86-64.

Direct backport of 2.4 fix that didn't get propagated to 2.6; original
comment follows:
<quote>
When I specify the NFS port for nfsroot (e.g.,
nfsroot=<dir>,port=2049), the
kernel uses the wrong port. In my case it tries to use 264 (0x108)
instead
of 2049 (0x801).
This patch adds the missing htons().

A bunch of asm/bug.h includes are both not needed (since it will get
pulled anyway) and bogus (since they are done too early). Removed.
