The code has long contained a backing_dev_info structure, but it
was never attached to anything. Initialize its use properly with
bdi_init, and attach it to i_mapping for every newly filled inode.
bdi_init and bdi_destroy are needed for proper initialization of
some percpu counters, otherwise we get some oopses.

When calling ctime on an afs_int32, always use a wrapper that assigns the
variable to a time_t before passing it in rather than conditionally doing
so on hosts with a large time_t. This eliminates a configure test,
removes a bunch of warnings in vos.c on platforms with 32-bit time_t, and
will make no difference in generated code with any decent compiler.

Use AS_HELP_STRING for every AC_ARG_WITH invokation and add proper quoting
to all of them. Based heavily on a patch by Simon Wilkinson, but with
less indentation and more quoting.

Add --with-linux-kernel-packaging configure flag which disables building
multiple kernels for different MP flavors, sets the kernel module name to
openafs.ko with no version, and installs the modules into the standard
Linux location.

exportfs - NFS translator:
- The exportfs code is updated for the new export ops. The changes are made
conditional on a new configure test that detects the new ops. fh_to_dentry()
basically replaces decode_fh and uses our own get_dentry function instead of the
now defunct find_exported_dentry.
- A check for fh_len=4 is removed - in testing this value is always 6, possibly
because of changes in the kernel code.
- The check for authtab in osi_nfssrv.c assumes that an undefined weak symbol is
0. On my system, an unresolved weak symbol in a loaded module gets the value
0xfffffffe (-2 or -ENOENT) - again, probably a change on the kernel side. Check
that the pointer is not an error constant using IS_ERR().
- In osi_vfsops.c, only use the export_ops bits if building the translator
afspag: the problem here was dealing with unresolved symbols
- afs_showflags is redefined in afs_pag_call.c so it's available for the afspag
module
- A new source file afs_warn.c gets the afs_warn* functions from afs_util.c.
This allows the afspag module to get the afs_warnuser function without dragging
in too many symbols. The new file is attached separately.
other:
- d_path() now takes a struct path argument - includes a new configure test
- osi_vfsmnt -> osi_vfsmount in osi_misc.c Looked like a typo?
- reorder the remove_proc_entry() calls - we need to remove the children before
the parent (introduced with my earlier patch)

The checkin message with each commit was inconsistent.

adapted from marc dionne's patch, but works more directly like the darwin port,
further, i'm guessing iget_locked will go away evewntually. maybe this is

FIXES 80463
Include linux/key-type.h in osi_groups.c, if it exists. Fix
do_sync_read test for recent kbuild (maybe break it for [some older 2.6]).
To prevent stripping, specify the '--disable-strip-binaries' option on
the ./configure command line. fileserver and volserver are never stripped.
When --enable-debug is specified, binaries will not be stripped by default.

1 - task_struct loses thread_info, which is now accessible through the
task_thread_info() macro. A configure test is added to deal with this.
2 - the SLAB_CTOR_VERIFY flag is gone
Background: OpenAFS is vulnerable to crashing in the linux kernel symlink
code when running on kernel versions between 2.6.10 to 2.6.12. This also
includes all RHEL4 kernels, because RHEL4 includes the code from 2.6.10. The
problem is that the symlink text caching API, page_follow_link() et al, is
unsuitable for network filesystems where the page cache may be invalidated
in parallel with a path lookup.
This crash can be triggered easily by doing a bunch of path lookups
involving symlinks (e.g., stat() on various files pointed to through links),
while simultaneously running 'fs flushvol' on the volume containing the
symlinks.
The simplest way to fix this problem is to disable the use of symlink text
caching when the kernel does not provide a usable symlink API.
