# powerpc: Avoid broken GCC __attribute__((optimize)) # # Commit 7053f80d9696 ("powerpc/64: Prevent stack protection in early # boot") introduced a couple of uses of __attribute__((optimize)) with # function scope, to disable the stack protector in some early boot # code. # # Unfortunately, and this is documented in the GCC man pages [0], # overriding function attributes for optimization is broken, and is only # supported for debug scenarios, not for production: the problem appears # to be that setting GCC -f flags using this method will cause it to # forget about some or all other optimization settings that have been # applied. # # So the only safe way to disable the stack protector is to disable it # for the entire source file. # # [0] https://gcc.gnu.org/onlinedocs/gcc/Common-Function-Attributes.html # # Fixes: 7053f80d9696 ("powerpc/64: Prevent stack protection in early boot") # Signed-off-by: Ard Biesheuvel <ardb@kernel.org> #
