-Subject: [PATCH] sparc: Fix -Wstringop-overflow warning
|
|
|
-
|
|
|
-Greetings,
|
|
|
-
|
|
|
-GCC 7 introduced the -Wstringop-overflow flag to detect buffer overflows
|
|
|
-in calls to string handling functions [1][2]. Due to the way
|
|
|
-``empty_zero_page'' is declared in arch/sparc/include/setup.h, this
|
|
|
-causes a warning to trigger at compile time in the function mem_init(),
|
|
|
-which is subsequently converted to an error. The ensuing patch fixes
|
|
|
-this issue and aligns the declaration of empty_zero_page to that of
|
|
|
-other architectures. Thank you.
|
|
|
-
|
|
|
-Cheers,
|
|
|
-Orlando.
