Okay, it turns out that it should be included in 5.15.y and 5.10.y, and I was missing it because unlike in 6.x, in 5.15.y and 5.10.y the problem only affects Clang builds (using the integrated assembler), since their versions of the commit in the Fixes tag are different to the ones in 6.1.y and 6.2.y. As you point out, 5.4.y and 4.19.y are also affected, and in fact 4.14.y is too. But porting to these kernels is harder, because they don't include 15d5761ad31d, which introduced asflags-remove-y. --gd5km4os56rsu45y Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- iQIzBAABCAAdFiEEH9wgcxqlHM/ARR3h+dvtSFmyccAFAmQ+ukUACgkQ+dvtSFmy ccDzcA/9EQ7cj4EYhSMOlYuQWTJMEfxQJgE1jKXV4/fVRzN744u9i1PnI6BHu4yi TVeP97xtYFQ0+M9cjWHbqUghZUVJNoMIvYYJnhhzRRjjo9QP9py5R1JPHZ83Es4k UeFnpo1uocxOmesGGLNz/LL5ie161BqkJ5REpuRXe3VBRqWd5idhraajI0W8vmrb g9siq3u8zJ2amlpigBPqNDk0vkFy9h68dHiafkoIUpiQ/dyLEk8CKT2VkQG2ZuG9 2C65bE14bTWbbrAvegqLpz7sykGwRiWNkAs62SjTwC9oyocPYi1YPjwGAEGQAjsO 8VFZ6nmweOpRuc/9Y5537SjsUlj8SGKX5LAytq7RICi+WwxAyNNnMn+MufJ3cx9V BmL+WO5PF+aXfGKcCvBBa2Uc/mTbkjO+uTKhmwUdeTTgyllF4nSE//Ao5U02lPad Pz6H3n69qApyt9k1DZfgf7F7guzp4e3J/Kfo/UsOTgc2OyBX3jLLeVOc5CN8EQXk 4RK+4+VbqCh7iEQsfRnZPopFM/GDffnKq+wY9VwaS8l9iEyvXz8QW5/rBouu1+La ESWryqQ3++fEloOeWeAmQbct9Ikk9hfjf0vk5CUkaNAljVoZkl0f0q/lWA3XqUqE LAJpBWDkZd/N8mp76gVCiHCmMUmJLYuDkNHWLbOlAoSzmMnaY18= =G2gG -----END PGP SIGNATURE----- --gd5km4os56rsu45y--
