[PATCH] 2TB files: add blkcnt_t

Browse Source 
Add blkcnt_t as the type of inode.i_blocks.  This enables you to make the size
of blkcnt_t either 4 bytes or 8 bytes on 32 bits architecture with CONFIG_LSF.

- CONFIG_LSF
  Add new configuration parameter.
- blkcnt_t
  On h8300, i386, mips, powerpc, s390 and sh that define sector_t,
  blkcnt_t is defined as u64 if CONFIG_LSF is enabled; otherwise it is
  defined as unsigned long.
  On other architectures, it is defined as unsigned long.
- inode.i_blocks
  Change the type from sector_t to blkcnt_t.
