[PATCH v9 13/20] x86/asm/crypto: Move .Lbswap_mask data to .rodata section

From: Josh Poimboeuf
Date: Fri Aug 07 2015 - 12:54:07 EST


stackvalidate reports the following warning:

stackvalidate: arch/x86/crypto/aesni-intel_asm.o: _aesni_inc_init(): can't find starting instruction

stackvalidate gets confused when it tries to disassemble the following
data in the .text section:

.Lbswap_mask:
.byte 15, 14, 13, 12, 11, 10, 9, 8, 7, 6, 5, 4, 3, 2, 1, 0

Move it to .rodata which is a more appropriate section for read-only
data.
