[PATCH] NTFS: Critical bug fix (affects MIPS and possibly others)

[PATCH] NTFS: Critical bug fix (affects MIPS and possibly others)

It fixes a crash in NTFS on architectures where flush_dcache_page()
is a real function.  I never noticed this as all my testing is done on
i386 where flush_dcache_page() is NULL.

Many thanks to Pauline Ng for the detailed bug report and analysis!
