Hi Victor,
It seems this patch broke kernel build after the recent patch to
upgrade -Wincompatible-pointer-types to an error:
00:00:56
/home/tcwg-buildslave/workspace/tcwg_kernel_1/abe/builds/destdir/x86_64-pc-linux-gnu/lib/gcc/aarch64-linux-gnu/14.0.0/include/arm_neon.h:
In function ‘vldap1_lane_s64’:

error: passing argument 1 of ‘__builtin_aarch64_vec_ldap1_lanev1di’

__vec, __lane);

note: expected ‘const long int *’ but argument is of type ‘const
int64_t *’ {aka ‘const long long int *’}
Looking cursorily at the code, should __src be casted to
(__builtin_aarch64_simd_di *) before passing it to
__builtin_aarch64_vec_ldap1_lanev1di ?
For more details, please see:

Thanks,
