llama.cpp b9112
llama.cpp b9112 fixes a CUDA grid-dimension overflow in im2col that caused failed kernel launches when processing audio longer than roughly 4 seconds with Conv1d encoders.
CUDA: handle OW > 65535 in im2col (2D and 3D) (#22944) `im2col_cuda` and `im2col_3d_cuda` both dispatch with `block_nums.y = OW`. CUDA caps grid Y at 65535. Conv1d encoders on raw 16 kHz audio with T > 65535 (~ 4 s) trip the limit -- e.g. SEANet at 11 s lands at OW = 176000 -- and the launch returns `invalid configuration argument`. Clamp `block_nums.y` to `MIN(OW, MAX_GRIDDIM_Y)` and loop inside the kernel with stride `MAX_GRIDDIM_Y`. Same in-kernel stride pattern already used for the z axis (`MAX_GRIDDIM_Z`). Both 2D `im2col_kernel` and 3D `im2col_3d_kernel` need the same fix.
