Subject: objtool, perf: Fix GCC 8 -Wrestrict error

Starting with recent GCC 8 builds, objtool and perf fail to build with
|
|||
|
|
the following error:
|
|||
|
|
|
|||
|
|
../str_error_r.c: In function ‘str_error_r’:
|
|||
|
|
../str_error_r.c:25:3: error: passing argument 1 to restrict-qualified parameter aliases with argument 5 [-Werror=restrict]
|
|||
|
|
snprintf(buf, buflen, "INTERNAL ERROR: strerror_r(%d, %p, %zd)=%d", errnum, buf, buflen, err);
|
|||
|
|
|
|||
|
|
The code seems harmless, but there's probably no benefit in printing the
|
|||
|
|
'buf' pointer in this situation anyway, so just remove it to make GCC
|
|||
|
|
happy.
