Vineet Gupta	eb1357d942	ARC: module: Fix !CONFIG_ARC_DW2_UNWIND builds ... commit d65283f7b6 added mod->arch.secstr under CONFIG_ARC_DW2_UNWIND, but used it unconditionally which broke builds when the option was disabled. Fix that by adjusting the #ifdef guard. And while at it add a missing guard (for unwinder) in module.c as well Reported-by: Waldemar Brodkorb <wbx@openadk.org> Cc: stable@vger.kernel.org #4.9 Fixes: d65283f7b6 ("ARC: module: elide loop to save reference to .eh_frame") Tested-by: Anton Kolesov <akolesov@synopsys.com> Reviewed-by: Alexey Brodkin <abrodkin@synopsys.com> [abrodkin: provided fixlet to Kconfig per failure in allnoconfig build] Signed-off-by: Vineet Gupta <vgupta@synopsys.com>	2017-01-18 11:17:44 -08:00
Vineet Gupta	d65283f7b6	ARC: module: elide loop to save reference to .eh_frame ... The loop was really needed in .debug_frame regime where wanted make it as SH_ALLOC so that apply_relocate_add() would process it. That's not needed for .eh_frame, so we check this in apply_relocate_add() which gets called for each section. Note that we need to save reference to "section name strings" section in module_frob_arch_sections() since apply_relocate_add() doesn't get that Signed-off-by: Vineet Gupta <vgupta@synopsys.com>	2016-10-28 10:10:28 -07:00
