Subject: [PATCH RESEND v4 4/5] libstub: Fix compilation warning for rv32
Date: Thu, 13 Jul 2023 17:07:59 +0200 [thread overview]
Message-ID: <20230713150800.120821-5-alexghiti@rivosinc.com> (raw)
In-Reply-To: <20230713150800.120821-1-alexghiti@rivosinc.com>
Fix the following warning which appears when compiled for rv32 by using
unsigned long type instead of u64.
../drivers/firmware/efi/libstub/efi-stub-helper.c: In function 'efi_kaslr_relocate_kernel':
../drivers/firmware/efi/libstub/efi-stub-helper.c:846:28: warning: cast from pointer to integer of different size [-Wpointer-to-int-cast]
846 | (u64)_end < EFI_ALLOC_LIMIT) {
