[PATCH 6.19 096/844] gendwarfksyms: Fix build on 32-bit hosts

[Sasha Levin]

From: Sami Tolvanen <samitolvanen@xxxxxxxxxx>

[ Upstream commit ddc54f912a551f6eb0bbcfc3880f45fe27a252cb ]

We have interchangeably used unsigned long for some of the types
defined in elfutils, assuming they're always 64-bit. This obviously
fails when building gendwarfksyms on 32-bit hosts. Fix the types.

Closes: https://lore.kernel.org/linux-modules/aRcxzPxtJblVSh1y@xxxxxxxxxxxxxxx/
