Don't pass NULL pointers to fput() in the error handling paths of the NOMMU
do_mmap_pgoff() as it can't handle it.
The following can be used as a test program:
int main() { static long long a[1024 * 1024 * 20] = { 0 }; return a;}
Without the patch, the code oopses in atomic_long_dec_and_test() as called by
fput() after the kernel complains that it can't allocate that big a chunk of
memory. With the patch, the kernel just complains about the allocation size
and then the program segfaults during execve() as execve() can't complete the
allocation of all the new ELF program segments.

/sys/devices/system/cpu/cpu#/topology/core_siblings

The descriptions in Documentation/cputopology.txt weren't very
informative, so I attempted a better description based on code
reading and hopeful guessing.
Updated Documentation/cputopology.txt with the better descriptions and
fixed some style issues.

Platform drivers registered via platform_driver_probe() can be bound
to devices only once, upon registration, because discard their probe()
routines to save memory. Unbinding the driver through sysfs 'unbind'
leaves the device stranded and confuses users so let's not create
bind and unbind attributes for such drivers.

In this patch:
http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=16dc42e018c2868211b4928f20a957c0c216126c
the check was added for another driver to already claim the same device
on the same bus. But the returned error code was wrong: to modprobe, the
-EEXIST means that _this_ driver is already installed. It therefore
doesn't produce the needed error message when _another_ driver is trying
to register for the same device. Returning -EBUSY fixes the problem.

The xfs_quota returns ENOSYS when remove command is executed.
Reproducable with following steps.
# mount -t xfs -o uquota /dev/sda7 /mnt/mp1
# xfs_quota -x -c off -c remove
XFS_QUOTARM: Function not implemented.
The remove command is allowed during quotaoff, but xfs_fs_set_xstate()
checks whether quota is running, and it leads to ENOSYS.
To solve this problem, add a check for X_QUOTARM.

Commit bd169565993b39b9b4b102cdac8b13e0a259ce2f seems
to have a slight regression where this code path:
if (!--searchdistance) {
/*
* Not in range - save last search
* location and allocate a new inode
*/
...
goto newino;
}
doesn't free the temporary cursor (tcur) that got dup'd in
this function.
This leaks an item in the xfs_btree_cur zone, and it's caught
on module unload:
===========================================================
BUG xfs_btree_cur: Objects remaining on kmem_cache_close()
-----------------------------------------------------------
It seems like maybe a single free at the end of the function might
be cleaner, but for now put a del_cursor right in this code block
similar to the handling in the rest of the function.

pte_unmap(pte - 1);
But if the loop breaks at the first loop, pte_unmap() unmaps invalid pte.
This patch is a fix for this problem.
