Merge branch 'fixes' of git://ftp.arm.linux.org.uk/~rmk/linux-arm

Pull ARM fixes from Russell King:
 "Two fixes for ARM and one for clkdev:

   - Fix another build issue with vdsomunge on non-glibc systems
   - Fix a randconfig build error caused by an invalid configuration
   - Fix a clkdev problem causing the Nokia n700 to no longer boot"

* 'fixes' of git://ftp.arm.linux.org.uk/~rmk/linux-arm:
  clkdev: fix clk_add_alias() with a NULL alias device name
  ARM: 8445/1: fix vdsomunge not to depend on glibc specific byteswap.h
  ARM: make RiscPC depend on MMU
