   4 Subject: [PATCH] ARM: 5882/1: ARM: Fix uncompress code compile for different defines of flush(void)
   5
   6 Because of the include of the decompress_inflate.c file from
   7 boot/compress/misc.c, there are different flush() defines:
   8
   9 In file included from arch/arm/boot/compressed/misc.c:249:
  10 arch/arm/boot/compressed/../../../../lib/decompress_inflate.c:138:29: error: macro "flush" passed 2 arguments, but takes just 0
  11
  12 Fix this by removing the define of flush() in misc.c for
  13 CONFIG_DEBUG_ICEDCC as it's already defined in mach/uncompress.h,
  14 and that is being included unconditionally.
  15
  16 Also use a static inline function instead of define
  17 for mach-mxc and mach-gemini to avoid similar bug
  18 for those platforms.
