kernel/module: Hide vermagic header file from general use
VERMAGIC* definitions are not supposed to be used by the drivers,
see this [1] bug report, so introduce special define to guard inclusion
of this header file and define it in kernel/modules.h and in internal
script that generates *.mod.c files.
In-tree module build:
➜ kernel git:(vermagic) ✗ make clean
➜ kernel git:(vermagic) ✗ make M=drivers/infiniband/hw/mlx5
➜ kernel git:(vermagic) ✗ modinfo drivers/infiniband/hw/mlx5/mlx5_ib.ko
filename: /images/leonro/src/kernel/drivers/infiniband/hw/mlx5/mlx5_ib.ko
<...>
vermagic: 5.6.0+ SMP mod_unload modversions
Out-of-tree module build:
➜ mlx5 make -C /images/leonro/src/kernel clean M=/tmp/mlx5
➜ mlx5 make -C /images/leonro/src/kernel M=/tmp/mlx5
➜ mlx5 modinfo /tmp/mlx5/mlx5_ib.ko
filename: /tmp/mlx5/mlx5_ib.ko
<...>
vermagic: 5.6.0+ SMP mod_unload modversions
