[CIFS] Allow reset of file to ATTR_NORMAL when archive bit not set
When a file had a dos attribute of 0x1 (readonly - but dos attribute
of archive was not set) - doing chmod 0777 or equivalent would
try to set a dos attribute of 0 (which some servers ignore)
rather than ATTR_NORMAL (0x20) which most servers accept.
Does not affect servers which support the CIFS Unix Extensions.

[CIFS] Fix oops when Windows server sent bad domain name null terminator
[CIFS] cifs sprintf fix
[CIFS] Remove 2 unneeded kzalloc casts
[CIFS] Update CIFS version number

Fixes RedHat bug 211672
Windows sends one byte (instead of two) of null to terminate final Unicode
string (domain name) in session setup response in some cases - this caused
cifs to misalign some informational strings (making it hard to convert
from UCS16 to UTF8).
Thanks to Shaggy for his help and Akemi Yagi for debugging/testing

Run this:
#!/bin/sh
for f in $(grep -Erl "\([^\)]*\) *k[cmz]alloc" *) ; do
echo "De-casting $f..."
perl -pi -e "s/ ?= ?\([^\)]*\) *(k[cmz]alloc) *\(/ = \1\(/" $f
done
And then go through and reinstate those cases where code is casting pointers
to non-pointers.
And then drop a few hunks which conflicted with outstanding work.

Fixes Samba bugzilla #4176
When users do not specify their domain on mount, 2.6.18 started sending
default domain instead of a null domain (which was the only way on some
servers to use a default domain). Users of 2.6.18 who did not specify
their domain name on mounts to certain common Windows servers that were
members of a domain, but not the domain controller, would get mount
failures which they did not get in 2.6.18
This fixes that issue and should remove complaints about mount
behavior changing.

In some places, particularly drivers and __init code, the init utsns is the
appropriate one to use. This patch replaces those with a the init_utsname
helper.
Changes: Removed several uses of init_utsname(). Hope I picked all the
right ones in net/ipv4/ipconfig.c. These are now changed to
utsname() (the per-process namespace utsname) in the previous
patch (2/7)

When a filesystem decrements i_nlink to zero, it means that a write must be
performed in order to drop the inode from the filesystem.
We're shortly going to have keep filesystems from being remounted r/o between
the time that this i_nlink decrement and that write occurs.
So, add a little helper function to do the decrements. We'll tie into it in a
bit to note when i_nlink hits zero.
