+Subject: [PATCH] MIPS: decompressor: fix build failure on memcpy() in
+ decompress.c
+
+The decompress.c file includes linux/kernel.h which causes the following
+inclusion chain to be pulled:
+linux/kernel.h ->
+ linux/dynamic_debug.h ->
+ linux/string.h ->
+ asm/string.h
+
+We end up having a the GCC builtin + architecture specific memcpy() expanding
+into this:
+
+void *({ size_t __len = (size_t n); void *__ret; if
+(__builtin_constant_p(size_t n) && __len >= 64) __ret = memcpy((void *dest),
+(const void *src), __len); else __ret = __builtin_memcpy((void *dest), (const
+void *src), __len); __ret; })
+{
+ [memcpy implementation in decompress.c starts here]
+ int i;
+ const char *s = src;
+ char *d = dest;
+
+ for (i = 0; i < n; i++)
+ d[i] = s[i];
+ return dest;
+}
+
+raising the following compilation error:
+arch/mips/boot/compressed/decompress.c:46:8: error: expected identifier or '('
+before '{' token
+
+There are at least three possibilities to fix this issue:
+
+1) define _LINUX_STRING_H_ at the beginning of decompress.c to prevent
+ further linux/string.h definitions and declarations from being used, and add
+ an explicit strstr() declaration for linux/dynamic_debug.h
+
+2) remove the inclusion of linux/kernel.h because we actually use no definition
+ or declaration from this header file
+
+3) undefine memcpy or re-define memcpy to memcpy thus resulting in picking up
+ the local memcpy() implementation to this compilation unit
+
+This patch uses the second option which is the less intrusive one.
