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.
