Subject: [PATCH] Remove missed ->fds_bits from cessation use of fd_set structs
 internally

Fix places where ->fds_bits needed to be removed as the core kernel no longer
uses fd_set internally for file descriptor table management.  There are two
places:

 (1) drivers/staging/android/binder.c

 (2) arch/mips/kernel/kspd.c

     Question: Should sp_cleanup() in the MIPS arch be using find_next_bit()
     or fls()?
