Three things bundled because they were verified together in the same deploy cycle on ohm (kernel built fresh on boltzmann 2026-05-18): 1. 0002 (Patch I) refined: refuse only multi-channel 5 GHz scans (n_channels > 1). Original Patch I refused everything, which blocked NM's per-frequency BSS discovery and made 5 GHz association impossible. Tighter guard preserves the storm fix and unblocks 5 GHz attachment via NM 802-11-wireless.band=a profiles. Verified on ohm with pkgrel=3: associated to BSSID c0:25:06:e6:5b:33 on 5240 MHz (ch.48), TX 150 Mbit/s MCS 7 HT40 short-GI vs 72.2 Mbit/s on 2.4 GHz. Pattern A still 0. Source-of-truth: marfrit/bes2600-dkms branch bes2600/scan-filter-5ghz commits 093a503 + 8cd10f4 (squashed into this single 0002 file). 2. 0003 (new): arm64 xor-neon Makefile workaround for GCC 15.2.1 strict pragma validator vs arm_neon.h target() blocks losing -ffixed-x18 under SCS=y. This is a defensive workaround; currently dead-coded (SCS=n below) but in place for the day SCS re-enable becomes possible (tracked in besser#20). 3. config: CONFIG_SHADOW_CALL_STACK=n override for the current GCC 15.2.1 toolchain issue. Restore to =y once GCC upstream fixes the arm_neon.h pragma interaction (besser#20). pkgrel bumped 2 -> 3. Refs: besser#1 (closed), besser#20, kernel-agent#25 (PR mirroring this into the kernel-agent patch tree — needs follow-up to pick up the refinement).
