byteswap: try to avoid __builtin_constant_p gcc bug

2016-05-06T00:38:53Z

This is another attempt to avoid a regression in wwn_to_u64() after that started using get_unaligned_be64(), which in turn ran into a bug on gcc-4.9 through 6.1. The regression got introduced due to the combination of two separate workarounds (commits e3bde9568d99: "include/linux/unaligned: force inlining of byteswap operations" and ef3fb2422ffe: "scsi: fc: use get/put_unaligned64 for wwn access") that each try to sidestep distinct problems with gcc behavior (code growth and increased stack usage). Unfortunately after both have been applied, a more serious gcc bug has been uncovered, leading to incorrect object code that discards part of a function and causes undefined behavior. As part of this problem is how __builtin_constant_p gets evaluated on an argument passed by reference into an inline function, this avoids the use of __builtin_constant_p() for all architectures that set CONFIG_ARCH_USE_BUILTIN_BSWAP. Most architectures do not set ARCH_SUPPORTS_OPTIMIZED_INLINING, which means they probably do not suffer from the problem in the qla2xxx driver, but they might still run into it elsewhere. Both of the original workarounds were only merged in the 4.6 kernel, and the bug that is fixed by this patch should only appear if both are there, so we probably don't need to backport the fix. On the other hand, it works by simplifying the code path and should not have any negative effects.

Revert "ipv6: Revert optional address flusing on ifdown."

2016-04-26T15:47:41Z

This reverts commit 841645b5f2dfceac69b78fcd0c9050868d41ea61. Ok, this puts the feature back. I've decided to apply David A.'s bug fix and run with that rather than make everyone wait another whole release for this feature. Signed-off-by: David S. Miller

ipv6: Revert optional address flusing on ifdown.

2016-04-25T19:33:55Z

This reverts the following three commits: 70af921db6f8835f4b11c65731116560adb00c14 799977d9aafbf0ca0b9c39b04cbfb16db71302c9 f1705ec197e705b79ea40fe7a2cc5acfa1d3bfac The feature was ill conceived, has terrible semantics, and has added nothing but regressions to the already fragile ipv6 stack.

[media] v4l2-dv-timings.h: fix polarity for 4k formats

2016-04-25T13:19:56Z
