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) { Signed-off-by: Alexandre Ghiti <alexghiti@rivosinc.com> --- drivers/firmware/efi/libstub/kaslr.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-)
