Subject: [PATCH] ARM: boot/compressed/decompress.c cleanup

Changes against Linus' tree

- Remove unused declarations and includes
- Remove the ARCH_HAS_DECOMP_WDOG define
  because it is only used in lib/deflate.c, which
  only the alpha architecture uses. No other architecture
  uses this define
- Remove the Trace<xx> and Assert functions which aren't used
  in decompression routines.

Tested successfully on Linux 3.3.0-rc3
