Subject: [PATCH v2 2/6] common: elf: fix warning on 32 bits architectures
Date: Thu, 23 Apr 2020 10:17:07 +0200 [thread overview]
Message-ID: <20200423081712.4022-3-cleger@kalray.eu> (raw)
In-Reply-To: <20200423081712.4022-1-cleger@kalray.eu>
When pointers are 32 bits wide and we cast a potentially 64 bits
value in it, the compiler will yield an error. Cast that value first
into a phys_addr_t to match the architecture pointer size and then
in a void *.
