[PATCH 0/3] Resolve ARM kCFI build failure in idpf xsk.c

[Nathan Chancellor]

Hi all,

This series resolves a build failure that is seen in
drivers/net/ethernet/intel/idpf/xsk.c after commit 9705d6552f58 ("idpf:
implement Rx path for AF_XDP") in 6.18-rc1 with ARCH=arm and
CONFIG_CFI=y. See patch 3 for a simplified reproducer on top of
defconfig.

I think this could go via hardening or net.
