-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.
