[PATCH net-next v2 0/4] Remove vermagic header from global include folder

[Leon Romanovsky]

From: Leon Romanovsky <leonro@mellanox.com>

Changelog:
v2:
 * Changed the implementation of patch #4 to be like Masahiro wants.
I personally don't like this implementation and changing it just to move forward
this this patchset.
v1:
https://lore.kernel.org/lkml/20200415133648.1306956-1-leon@kernel.org
 * Added tags
 * Updated patch #4 with test results
 * Changed scripts/mod/modpost.c to create inclusion of vermagic.h
   from kernel folder and not from general include/linux. This is
   needed to generate *.mod.c files, while building modules.
v0:
https://lore.kernel.org/lkml/20200414155732.1236944-1-leon@kernel.org
----------------------------------------------------------------------------

Hi,

This is followup to the failure reported by Borislav [1] and suggested
fix later on [2].

The series removes all includes of linux/vermagic.h, updates hns and
nfp to use same kernel versioning scheme (exactly like we did for
other drivers in previous cycle) and removes vermagic.h from global
include folder.

[2] https://lore.kernel.org/lkml/20200413080452.GA3772@zn.tnic

------------------------------------------------------------
1. Honestly, I have no idea if it can go to net-rc, clearly not all my
patches are fixes, so I'm sending them to the net-next.
2. Still didn't get response from kbuild, but it passed my own
compilation tests.

Thanks

[PATCH net-next v2 1/4] drivers: Remove inclusion of vermagic header

[Leon Romanovsky]

From: Leon Romanovsky <leonro@mellanox.com>

Get rid of linux/vermagic.h includes, so that MODULE_ARCH_VERMAGIC from
the arch header arch/x86/include/asm/module.h won't be redefined.

  In file included from ./include/linux/module.h:30,
                   from drivers/net/ethernet/3com/3c515.c:56:
  ./arch/x86/include/asm/module.h:73: warning: "MODULE_ARCH_VERMAGIC"
redefined
     73 | # define MODULE_ARCH_VERMAGIC MODULE_PROC_FAMILY
        |
  In file included from drivers/net/ethernet/3com/3c515.c:25:
  ./include/linux/vermagic.h:28: note: this is the location of the
previous definition
     28 | #define MODULE_ARCH_VERMAGIC ""
        |

Dave,

I see in the patchworks that this series is marked as "Needs Review/ACK".
Can you please help me to understand who is needed to be approached?

Thanks
