Remove the usage of LASSERT() and CLASSERT() from lustre_idl.h, so
that it is usable from userspace programs if needed. These have
crept in over the years, but are not intended to be there.
The CLASSERT() checks for fid swabbing were largely redundant, and
have been moved to lustre/fid/fid_handler.c.
There are still a few LASSERTs that need to be removed when FID-on-OST
is landed, but I don't want to remove them before that code lands.
There are also uses of CERROR() that could be removed at that time.

Mnt root dentry will never be revalidated, but its d_op->d_compare
will be called for its children, to simplify code, we use the same
ll_d_ops as normal dentries.
But its attribute may be invalid before access, this won't cause
any issue because it always exists, and the only operation depends
on its attribute is .permission, which has revalidated it in lustre
code.
So it's okay to remove ll_d_root_ops, and remove unnecessary checks
in lookup/revalidate/statahead.

Pull parisc updates from Helge Deller:
"The three major changes in this patchset is a implementation for
flexible userspace memory maps, cache-flushing fixes (again), and a
long-discussed ABI change to make EWOULDBLOCK the same value as
EAGAIN.
parisc has been the only platform where we had EWOULDBLOCK != EAGAIN
to keep HP-UX compatibility. Since we will probably never implement
full HP-UX support, we prefer to drop this compatibility to make it
easier for us with Linux userspace programs which mostly never checked
for both values. We don't expect major fall-outs because of this
change, and if we face some, we will simply rebuild the necessary
applications in the debian archives"
* 'parisc-3.14' of git://git.kernel.org/pub/scm/linux/kernel/git/deller/parisc-linux:
parisc: add flexible mmap memory layout support
parisc: Make EWOULDBLOCK be equal to EAGAIN on parisc
parisc: convert uapi/asm/stat.h to use native types only
parisc: wire up sched_setattr and sched_getattr
parisc: fix cache-flushing
parisc/sti_console: prefer Linux fonts over built-in ROM fonts
HPFS needs to load 4 consecutive 512-byte sectors when accessing the
directory nodes or bitmaps. We can't switch to 2048-byte block size
because files are allocated in the units of 512-byte sectors.
Previously, the driver would allocate a 2048-byte area using kmalloc,
copy the data from four buffers to this area and eventually copy them
back if they were modified.
In the current implementation of the buffer cache, buffers are allocated
in the pagecache. That means that 4 consecutive 512-byte buffers are
stored in consecutive areas in the kernel address space. So, we don't
need to allocate extra memory and copy the content of the buffers there.
This patch optimizes the code to avoid copying the buffers. It checks
if the four buffers are stored in contiguous memory - if they are not,
it falls back to allocating a 2048-byte area and copying data there.

Previously, hpfs scanned all bitmaps each time the user asked for free
space using statfs. This patch changes it so that hpfs scans the
bitmaps only once, remembes the free space and on next invocation of
statfs it returns the value instantly.
New versions of wine are hammering on the statfs syscall very heavily,
making some games unplayable when they're stored on hpfs, with load
times in minutes.
This should be backported to the stable kernels because it fixes
user-visible problem (excessive level load times in wine).
